welcome to the recording of the exhibitor presentation from May 27th, 2026 new smart glasses for the visually impaired Biel Glasses SL enjoy watching hi my name is Jaume Puig I'm the CEO and co founder of Biel Glasses and uh um uh no I cannot admit the the the for the recording of the session should this session is being recorded by the organization of uh SightCity so I guess that uh SightCity will uh publish this this session uh later on OK I don't know I don't know the details but you can ask OK and OK and I'm admitting other people right now still waiting okay so uh well uh we I will want to try to do this session uh like a bit of a workshop so I have a presentation but I would like you to ask me whatever you you want and and in any any moment OK uh OK so let's start well today I'm came here to talk about our solution uh Biel Smart Gaze uh this is a solution that we created because of my son Biel who was born with a low vision and um I have our last version here I'm trying it's not that I have a big camera here but I will try to show you how it works it consists of a device that I can wear like this and the glasses OK and glasses are connected to the device like this and this device helps the people with low vision to move around safely uh it indicates any obstacle or risk for for them so they can move around safely and it also improves vision as you can you will I cannot demonstrate how the glasses work right now but we have a presentation that you will see how they work okay so let's start I'm sharing my screen we like to work with hands ist das einer unserer dienstleister der für meine landung aufpassen muss so you should be seeing my screen right now yes we see it OK so as I said we started the our project because of my son Biel when he was 3 years old we realized that realized that something was wrong with him because uh it took too long for him learning to walk and even when he started walking he was falling all the time and getting lost and after visiting many doctors we realized that the problem was with his eyes because he has a low vision okay and his main challenges were the mobility issues falls and collisions and well actually we started this project uh with my son with a child but later on we realized that the most of people that suffers low vision mobility issues because of it are elder people people over 50 years old for them this the consequence of uh this mobility issues the falls injuries and dependency and isolation are much worse and 50 forty percent of patients with a vision fall at least once a year and 36% of them suffered medical consequences because of these falls and in a study that was carried out in UK as a consequence of that they realized that 33% of people who had hip fracture had also low vision so it's a major cause of hip fracture our solution is as I told you these are the Biel Glasses the glasses that adapt the reality to the remaining vision of the patients so they can move around safely and we also have vision improvement functions like zoom and contrast and light adaptations to uh provide a a complete solution I have some questions here so as you can see this is a medical device is already certified and it's patented and I want to to highlight that this is the newest and latest version that uh we are about to release and it improves a lot the the size reducing the size and making it lighter and much more discreet than any previous version and uh this is uh thanks to the use of AI that allowed us to reduce the number of sensors that we that we were using in in in previous version so we can now we can make it look like like quite a normal a common sunglasses moreover as I said before in order to wear it more comfortable uncomfortably you can sorry we have the Bellas Margay's Aura this aura is the new version the one Aura means air in Catalan and um the we also have the order back so you can wear it easily uh uncomfortably like in you can see in this video for doing so we we use different technologies robotics uh AI similar to the one of autonomous driving uh AI segmentation and mixed reality as I said before we had a long evolution long way to to reach the the current version we started in 2021 with the first version and I'm sorry for the accessibility of this of this screen because there is a lot of information but what I want to to show with this screen is that it has been a long way of research and development to get to to the current stage of the product you can see for example here the difference among the the last version that we actually we were here in Inside City one year ago and we were showing this previous version it's much bigger and now you can see this is by the way this is Biel right now he's 14 we started when he was three and now you can see here the the the difference of the size and and and the aspect of of the glasses so now we will get into how the glasses work uh this is the the function of obstacle detection obstacle detection okay it uh use graphic indications and audio cues synchronized to show the if there is any obstacle positive or negative positive means over the ground negative means like holes descending the steps everything that is below the ground uh so the patients can avoid it so this is an example of a quite a risky a street a this is in Barcelona and you can see that we have a chair in this case uh in a road that is difficult to know uh if you are working in the where where the the the the cars can can go through or you are in the the walking side so and you you there are plenty of obstacles that uh you may not realize if you have low vision like in this case like you have a tunnel vision like it may happen in the case of glaucoma or um redinitis so in this case the the screen of the glasses will be showing something like this an arrow pointing to the obstacle and then a bounding box around the obstacle uh so the user can identify which obstacle are being indicated like this so the user will be seeing the arrow pointing to the obstacle and then if he moves his eyes following the arrow to get to know what's the potential risk that the glasses are pointing to then uh he or she or she uh should see the this chair that uh the user should avoid in case that the obstacle is right in front of the user arrows are not good to way to to point at it so uh in this case we have again this low vision simulation and then the glasses in this case will show a ring so the user will see this ring and it means that the the obstacle is right in front the color of the of the indications depend on the distance in this case you can see um orange ring but actually depending on the distance it could go from yellow up to red this is a scale of of colors that that goes from the minimum minimum uh from the maximum distance that would be yellow and to the minimum distance that should be red this is something that can be configured to fit with the conditions of the of the patients so if the patients have any problems recognizing some uh colors then the optician can configure the device to use other colors but at the end the the the different colors mean always different distance this is a video example so you get you okay are you going to play it again we have the audio indications that synchronize with the video indications that there is we have this arrow and then we have this bounding box and then if you move forward you can see that both the arrow and the the bounding box got more orange because we are getting close to the to the obstacle and then also the sound changes because the the sound also can change depending on the distance to the obstacle dice si se da el ejemplo OK eh understood any question so far I see somebody in the chat the sound well seems that well I'm sorry because I'm you know this is a life from Frankfurt from SightCity I don't have much uh uh an infrastructure for doing online webinar so the sound is the one that I'm speaking from my laptop uh I will try to speak as clearly as possible okay you want me some to repeat anything let me know yes well everything not everything I mean we are not doing different glasses for different people the device is the same for everybody but there are plenty of functions that can be customized by the optician there first of all there are there is the possibility of the for for the user to to activate and deactivate some of the functions with these buttons that you can see here OK and also in the glasses so for example we will see later but zoom window and uh the sound and all the functions can be activated and deactivated by the user and also the opticians they have a configuration tool uh the technicians the the the eye care specialist configuration tool to uh to customize the size of the arrows uh the the the colors the the size of the square I mean the the square the bounding box has the size of the the the obstacles that we are pointing at so it is not something that we should customize because uh if we had uh let's say a size for the bounding box it we do not fit with the different obstacles okay but yeah the arrow the arrow and the ring is something that we can that that uh the eye care specialist can customize and not only with the size the size the colors and the position position within the visual field of the of the patient OK so let's go on I'm going forward this this other case this is a negative obstacle this is also in in Barcelona it's quite funny but we had places like that in the city and um so in this case the user may see something like this so it could be dangerous so the device will show something like this so in this case is a blue arrow so we are using a complete different colour scale for negative obstacles and uh in this case is uh starts with a with blue and points again we have this bounding box around this negative obstacle so the user will see the arrow and then the bottom box and we'll know that the the obstacle is negative because in this case the arrow is is blue and for positive obstacle uh a blue is not included in the scale so positive go from in this case from yellow to red and then uh the the the blue scale is from uh dark blue to light blue you can see an example here OK the also the sound is different as you heard OK the the sound is completely different of the bells and the drops of water that were for the positive obstacles so far we explained the the the the function of obstacles detection and now we will go through the vision improvement functions yes so there are zoom zoom in zoom out we have light adaptations contrast improvement and edge enhancement so let's start with the zoom window in the same situation we have the also again the simulation of low vision and then the user can activate when when the user wants not not necessarily all the time a zoom window this the place of this zoom window is something that should be configured by the the eye care specialist and that could be any place in the in the screen and also the size OK so in this case this zoom window has been zoomed out zoom out is useful for when the user want to have more context to get to know more about the whole um environment scenario uh so because it is able to fit more information within the visual field and so the user if moving uh his eyes or her eyes to to the place where the the window is uh can see the whole street but also it's possible to do zoom in for example if he realized that there is something that may be uh like in this case a hole in the in the way a hole for the for this tree then can zoom in and to to get to know exactly what what is the problem then again I'm checking if there is any and there is another question yes OK OK again this is another question about the the arrow size yeah the arrow size can be customized no problem arrow the arrow size arrows color arrow position within the within the screen so light adaptations this is the same street it's saying in the in the in the evening so there is a low light condition okay and then it may cause night blindness for people with retinitis for example so what the glasses may do adapting light is that the user may see it like this okay it is not that the glasses are able to see by night but this light enhancement this intensification of light allow the users to to be able to walk around some more hours especially uh uh in in winter where the where light uh where the light uh starts to to get dimmer uh soon okay we also have the possibility of improving contrast it also depends these these glasses are not intended for an specific condition so we have some functions that can adapt to the specific problems needs of each patient for example we had patients suffering Stargardt disease that they had problems with the contrast that they wanted the the the the image to be to have more contrast so we can increase the contrast as you can see here then we have the edge enhancement edge enhancement is again to make the most of the remaining vision to to allow the users to improve their capacity of recognizing things with the remaining vision so again the same situation same image and in this case you can see that we enhanced the edges of all the objects the the not only the obstacles everything in the street this this is an example but uh in this case we are painting the the edge in in white but we can do the other way I mean we can do the edges in black so it depends again on the on what is more sweetable for for each patient but at the end they will see there will be it will be easy for them to recognize things with this function so I'm restating again the functions obstacle detection at positive obstacles negative obstacles holes descending a stairs etcetera visual and visual and audible cues zoom window zoom in and zoom out adaptation to light conditions to adapt to avoid the the the light conditions adaptations is not only to avoid night blindness it also works to avoid enlightenment to avoid problems with the changes of in in light when um especially when people go from inside to outside so um for example right now here in Frankfurt it's very sunny outside so if somebody comes out with a patient that may have retinitis or glaucoma they have they have a lot of difficulties for adapting to the changes in in in light so wearing the glasses the glasses will reduce the change so the the the the light within the building and without the building will be quite the same so there is no need to this adaptation and this uh problems that they may have for with with these changes and so we have also the image enhancement that you have seen and this full customization that we have been also talking about the the all these functions not only the the size of the arrows but also the vision enhancement functions the contrast the the the edge enhancement and the the light adaptations this something that can be customized to fit with the specific condition of each user by the Acer specialist and now we have some testimonials of of uh patients that have been using our glasses and they are uh we have subtitles they are spoken in in Spanish uh for somebody that cannot read uh for the case that somebody cannot read the Spanish sub the English subtitles I will explain later what they say me llamo Alejandro eh vivo en martorey me estoy afectado de una Baja visión y de glaucoma ahora me defiendo con un con el bastón y es LA única Manera ahora de moverme a día de hoy en tema de movilidad sería muy muy avanzado ya vería algo más de lo que veo yendo con el bastón Si encima tienes LA ayuda de unas gafas que te pueden facilitar LA visión eh no tropezar con los con toldos ni con pérgola ni con árboles ni nada y tú ves pues escaleras y todo hombre yo creo que que es un buen avance okay so Alex is the name of of this eh of the user eh he said that he he's suffering low vision because uh a glaucoma and a eye ictus and um so um now he's he has about 1% vision and uh he needs the cane all the time the cane and also uh for going out the he needs going with with her his wife and um in this case what he's saying about the glasses is that with the glasses uh as you can have seen he's able to to descend the steps and to perceive things that even with the cane he cannot perceive like potential obstacles that may be uh at the height of his head this is a an important thing we are in this in this example you can see that Alex was walking without the the the cane to test the glasses but this is only for testing I mean we are never never advising the users who use the cane to stop using the cane so the glasses can help can improve their ability to recognize things to avoid obstacles but uh if they're using the cane uh it's better to keep using the cane OK it's more safe it's more secure so the glasses should be something that improve the the uh the capacities of the that the that the cane is is giving them to to move around and to avoid obstacles moreover you maybe you have you realized that during the video that he's not wearing the current version this this test has been done with the with the previous version of the of the glasses but it works exactly the same okay uh so you can hear realize also about the the reduction of of the size that that I've been talking previously Hola me llamo Ivana y tengo Baja visión debido a esta discapacidad visual moverme por LA calle siempre ha sido un desafío puedo chocarme o caerme debido a obstáculos así que dependo de IR acompañada en los últimos meses he podido probar las gafas inteligentes de Biel Glasses estas gafas utilizan inteligencia artificial para analizar lo que me rodea y me proporcionan indicaciones accesibles tanto visuales Como auditivas Que puedo percibir fácilmente y que me permiten caminar con seguridad y confianza con ellas puedo ser MáS independiente e IR sola por lugares donde antes no podía well uh Ivana was a participant of a pilot project that we carried out in Barcelona with more than 40 patients uh also with the previous version of of our device the one that we were showing here in the SightCity a one year ago and uh he's explained that uh he cannot he cannot move around alone and that the last months because the the the the pilot project lasted for about 3 months and she participated in in this pilot project and she she was able to move as you have seen in the video avoiding any kind of of obstacles and so she can move now using this glasses for for in places that that she could not be moving uh alone so and this is uh Fran Hola Buenos días Mi nombre es ferrán eh soy una persona que tiene eh retinosis pigmentaria y el hecho de tener esta enfermedad em el impedimento principal que tengo para para desplazarme el día a día es eh que me tropiezo me tropiezo mucho debido a mi mi campo visual que es muy muy muy estrecho entonces mi principal problemática es eso que no tengo suficiente campo visual y es muy fácil pues que me me tropiezo constantemente no veo los obstáculos que tengo a mi alrededor ferran si tuvieras que describir en una frase LA experiencia de usar las gafas Biel Glasses qué dirías me permite hacerme una idea mucho más detallada de lo que tengo delante de mí y evitar posibles eh posibles colisiones en este vídeo le vemos caminando con las gafas de Biel Glasses observa cómo Las gafas le señalan LA presencia de obstáculos y agujeros a TRAVéS de señales visuales y sonoras en este ejemplo las detecciones se marcan en amarillo y el agujero en azul parce que si tu Mets pas les pieds dedans euh tu fais pas les RèGLES euh tu respectes pas les RèGLES Las señalizaciones se sitúan dentro de su campo visual de modo que pueda percibirlas y los sonidos son complementarios a LA señalización okay so in this case um this video is uh have a part of the testimonial of Iran and also we had a part of explanation of of of but using actually it was recorded from the the glasses that he was wearing during this this uh test and well what he's saying is that uh he's suffering uh retinitis and they had problems for for uh walking around because he runs onto obstacles and and collides with them and uh when we asked him what is the the the best advantage that he's having his feeling with the glasses that he can now perceive all these obstacles and be able to avoid these obstacles and you have seen in the demonstration that that uh in the way that he was working there were both uh positive and negative obstacles and how it they they were shown to him so um just a little bit comments little comments about um how the glasses should be used and and how we sell it okay before using we are not selling it in in in directly to the to the patients we always sell the the glasses through professionals because this is a medical device okay this is not something that could be directly directly bought by by the user and and start using it because it needs to be customized so first of all there should be a vision assessment of the user by a professional an ophthalmologist or an optician optometrist uh depends on on on the country depends on regulations but at the end should be uh this assessment and then the glasses should be customized the configuration should be customized uh with the participation of the of the user so the user and the the the the the the the eye care specialist uh puts the the glasses on on the on the user so the user start wearing the glasses sitting not moving and then all these um configurations the size of the arrows the colors the the where the the the the glasses the the arrows should be placed within the visual field of the user the the zoom window the size of the zoom window and the the the even the the volume of the of the audio many different configurations can be configured by the AK specialist using an applications a tablet and do a single an application within a tablet it takes about the whole process of configuring actually it could be done in technically in five minutes but as you should be trying different possibilities with the patients to to get to know which is the sweet spot I mean the the the best so for example with the with the contrast uh that that that we you can adjust the contrast and you should look for the best um contrast the best uh configuration for the user or the same with the with the size of the colors if for example people with reduced visual field if the the arrows are too big maybe that the the arrows were hampering the the visual field so uh depending of the visual field maybe that uh the this arrow should be reduced but the if the user has also uh low acuity then if you reduce the size too much then maybe they don't see the arrows so you should the the the eye care specialist should look for the the best uh combination of size and colors that fits the the the the condition of of the user so the whole process process takes about half an hour and later on the the specialist should train the users should explain the users how to use the glasses to to how the glasses work the the way that I the the what what I explained to you and there should be some training uh the the user should start working uh being uh with uh with a specialist uh that that guides the user uh so the user gets used to to wear the glasses uh to avoid any problem and and this training depends of of the user but may take a couple of sessions of uh 1 hour each depends on uh a lot on on on on on it on it on each patient OK any questions so far yes we have one question okay here how do you change from normal to high contrast or high light no it is not that I mean the glasses work automatically so it is not that the for for the light adaptations the glasses adapt themselves so they they don't need to do the the users don't need to do anything in the case of contrast if the the the users want to increase the contrast they can use one of the of the buttons that we have here that to to activate the the contrast or the h uh the the the h enhancement so contrast and uh and edge enhancement are on demand light adaptations your work automatically but when the the eye care specialist configure the glasses this light adaptation there is a range of adaptation and can be configured by the by by the eye care specialist and also the same for contrast and and and h uh enhancement hey it's okay understood hope so um again um we are selling it through this is our business model so we sell it through optical stores ophthalmologist it's not that we are selling through ophthalmologist but ophthalmologist are very important to prescribe the glasses so we collaborate with ophthalmologist so they know that uh for the cases of of of patients that they may need a solution for in order to be independent to move around safely that they can advise them and then can send the the the these potential users to uh optical stores which specialize in low vision where they can get the this device and the retail price is 4,900 euros and this is including the first year of service fee I have another question here how is the image they use it's full screen well it is the the full screen I mean the screen the screen in the glasses is more than 50 degrees of of screen okay uh there are two ways of wearing the glasses the virtual reality or the the camera mode and the augmented reality mode I've the examples that I've shown is in the camera mode it means that the user is seeing through the camera but there is also the possibility of using the augmented reality mode in the augmented reality mode the users see through the the the glasses so it's like real sunglasses and they all only see the indications so in the augmented reality mode they have the same visual field that they will have that they would have without any glasses in the camera mode where where they see through the camera there is a limitation of the screen of the of the glasses but not the the the the limitation is on more on the screen of the glasses not in the camera the camera is very wide so you have more than 100 degrees of the of the of the camera this is why when you use the zoom window and you do zoom out in the zoom out window you may see more that that that what you see in the main screen I hope that it answers your question Augustine okay and well I was talking about the this price including the service fee and the service fee is comes from the from the 2nd year on and uh includes the software upgrades it also includes something that it is very important it is in the case of the condition of the user the disease that the user is suffering or whatever evolves and the user needs any configurations any reconfiguration to to change the setup of the of the glasses for example changing the size of the position of the any indication or whatever then the user can go again to the optician or to the AC specialist and ask for a reconfiguration and to to to customize again the glasses to fit this uh new condition that the the the that the user may have and it also includes a 50% discount on renewal of the glasses so after 3 years the users can ask for a new device new version uh with a 50% discount and we are doing this because uh we are always evolving our device you have seen before the the the changes in the device that we had since 2021 what was our first prototype so we don't want the users to use old devices we want because old devices will mean that they will not be benefiting from the new improvements in software and hardware and whatever and there is a limit in the we we can always upgrade the software but for example if we reduce the size of the glasses this something that we cannot upgrade in the software okay and so after 3 years the the users can have this they have the right to to have this new version of the the latest version of the device with 50% discount this is not compulsory it means if they don't need to do so they can keep the device that they have but they have this discount if they want to to get a new version comparing with other devices eh we are the only device that solve mobility issues and at the same time improves vision and there are other smart glasses and other wearables for for low vision but uh we are only that focus on mobility and we also have other complementary functions that you have as you have seen you can see here in this graph again I'm sorry because this is not very accessible but this graph is showing the needs that different devices are solving for the for the potential users so there are all the devices that are more intended for reading or for seeing TV or recognizing people or recognizing objects we focus on mobility because we focus on people who suffer mobility issues like because mostly they it happens the most when there is peripheral vision loss like in glaucoma retinitis but there are other conditions actually my son he has an optic nerve hypoplasia uh uh and causes the same so at the end uh mobility is uh the problem that happens the most when there is peripheral vision loss there are other solutions that may be more intended for reading but we also provide this zoom window that may help to read or also to recognize other objects or seeing TV or or recognizing people OK so at the end we want to the the the the users to have a single solution that may be able to solve the most of their uh needs nevertheless the glasses are not intended for seeing TV at home okay it's intended this is a device for mobility it doesn't mean that they cannot use it but this is not the the glasses are not designed for this for this goal we have tested the the glasses in every mobility situation in either in uh in the lab and in the streets in the lab we we collaborated with the faculty of optometry of the UPC UPC University in in Barcelona we built there a a lab which was funded by EIT Health which is a body of the European Union so we were able to build that a lab where we were able to measure the uh improvement for example in the distance of detections of obstacles in the rate of detections and either positive or negative or whatever and we also uh proved it in in the street as uh I mentioned we we carried out uh several pilots uh the biggest of uh them in Barcelona uh with 40 patients um funded by the Barcelona City Council to improve the accessibility of public areas in in Barcelona and the the main result of the of the of the tests was that more than 95% of obstacles were detected by and indicated by by the device okay so I'm trying to restate the advantage of a or last version of Bea Las Margaritas Bea Las Margaritas Ora it's easy to wear we it's very easy to use it's it's intended to to be used by anybody there is no need to know about technology or whatever most of functions have work automatically it makes use of of remaining vision and improve it improves the remaining vision it leaves your hands free so you can do whatever you want with with uh activities with your hands it can be customized for each user to to make the most of this remaining uh vision and in this last version that we are about to to start to commercialize is sleek and light and discreet so that's it uh I'm leaving so if you have any question any comments hello this is Jacob speaking nice to meet you nice to meet you Jacob um a short question are there any spoken hints or just visual errors or other things do if you for example if you can only see colours but you cannot see different forms um are the hints also spoken of the instructions what in front of you what could be dangerous for you or not well if you you mean if you only see colors you you you and you mean you would not be you or or somebody would not be able to see the arrows is what you mean yes or detect is the arrow showing to the right or to the left side are there any spoken hints about this well this is why we have the audio the audible indications okay aural indications are complementary to video indications audio indications are spatial so it means that if you are able to see that there is a red indication okay even if you don't see the arrow where it's pointing at you you will hear the the the the bell I see so the different sounds for different arrows and different colors the the the direction of the bell with the you it's a special sound so so you I see be able to hear uh where the sound is coming from I see thank you you're welcome well uh I see another um coming from Andreas um yeah it's it's a possibility actually we had a some version that had this color filters as an as an as a warning but you know we try to make the most of the remaining vision so if there is a remaining vision with the arrows the indications can be more precise than with just uh um color filters because uh color filters are not pointing are not pointing anywhere nevertheless uh with the with the with the audio you can complement this in the case of the of the arrow is too big yeah it it depends we can do the arrows as small as we well the the the I mean the acre professional can do the arrows as small as required as far as it can they can be seen so there are users that they have very reduced field but within this visual field they can see quite well for example my son he's able to read quite well even small letters he has reduced visual field but within this visual field he can see quite well okay so in this case we can do the arrows quite small and they will work nevertheless again this is a combination we have the combination of the sounds and the and the arrows and we what what what should be done for each user is to combine both to make the most of the perception capacity of the user nevertheless unfortunately there may be users that cannot benefit of the of the glasses if so far people who is completely blind cannot make use of the glasses um we are working on the on the audio to to improve it and to and to try to give as much information as possible with the audio indications but we don't have yet studies that demonstrate that the with only the audio the users can walk safely so we don't we cannot recommend right now to use the glasses if there is no vision at all any other question again it's something that uh it's evolving uh and um we are working so to improve this audio so we really respect and we are collaboration in collaboration with with uh some associations uh uh in Spain patients uh with glaucoma and to get to to get to the point that the glasses can be used by the blind too and but we we need to we need to do more trials uh with the special sound to be sound to to get to the the point that that we can be sure that they work for them OK so thank you very much we hope you enjoyed this presentation for more information visit sightcity.net/O031052 thank you and see you at the next SightCity
