Bionic contact lens will give sensory vision to the blind

Bionic contact lens

Much like a braille is used provide a sense of vision to the blind, now touch can also be deciphered to the brain and visualize what the blind is looking at. Israeli researcher Professor Zeev Zalevsky (Bar-IIAN University) has invented new bionic contact lens that uses electrical signals from transponder and then transmits that encoded image via the lens to the wearer’s camera, thereafter the image is translated into tactile sensation that can be felt by the visually impaired. In the eye there are 600 times more sensors in the cornea than the fingertips so the blind can sense the image at very high resolution. This sensation is very close to feeling person’s face with one hand. Somehow this new innovation differs from the artificial retinas as they last only couple of years and provide image at very low resolution.

Touchscreen Braille Phone for blind people developed by Indian student

Touchscreen Braille Phone  by Sumit Dagar

Tactile mobile phone concept by Peter Lau is quite intuitive and taking a huge leap forward from the concept stage an Indian post graduate student Sumit Dagar from the National Institute of Design (NID) has made his own version of a smartphone for blind. Deemed as the world’s first smartphone for blind and visually impaired users, Braille Phone is based on a never before seen haptic touchscreen that has components that can elevate and depress to create patterns that can be read by the blind just like a braille. To represent the character or letter the phone’s screen has grid of pins that move up or down. The basic concept of this smartphone is based on the Shape Memory Alloy technology that expands and contracts to the original shape after use.

Touching tactile mobile phone concept by Peter Lau designed specifically for blind people

Touching tactile concept mobile phone for blind and visually impaired

We all go on cribbing about our touchscreen smartphones with a very user friendly interface but people who are blind can’t even think of using them, simply because they don’t have any other means of operating the phone. Keeping this in mind an intuitive designer Peter Lau has come up with the design of a tactile mobile phone for the blind, visually impaired, elederly users and sighted users which is good news for people with such unfortunate disability. Called as Touching, this concept mobile phone works on claw and fingertip action to initiate various functions like dialing numbers or searching through the phonebook for specific contacts. This ergonomic user experience comprises fourteen functional button that are easily locatable with finger tips or hand and for ease of use the main button are located in a grip for fast navigation with thumb. Although there is no outgoing SMS function right now but one can send SMS by recognizing the voice message and then translating it to send the message. On top of that the mobile phone has voice recording, MP3 playback, NFC (Near Field Communication) and wireless power recharging capabilities.

Eye microchip device infuses new hope for the blind who want to see this beautiful world

Eye experts in UK have come up with a very innovative solution to give bling eyes of their own so that they can see the world in colors just like we do. So far the technology seems to be going well as the initial batch of British patients to receive electronic microchips were regaining basic vision just weeks after fitting the microchip inside the eye. Lending new hope to patients suffering from retinitis pigmentation (RP), a genetic condition responsible for permanent blindness, Retina Implant AG (leading subretinal implants developer) successfully implanted the wireless microchip inside to RP suffering patients.

Shortly, ten more British RP patients will be fitted with this device by the team led by Tim Jackson, a consultant retinal surgeon at King’s College Hospital and Robert MacLaren, a professor of Ophthalmology at the University of Oxford and a consultant retinal surgeon at the Oxford Eye Hospital. Robin Milla, aged 60 from London is one of the patients fitted with the microchip and 1500 electrodes implanted below the retina and says that since the device was installed he is able to detect light and identify outlines of objects.
