Sensor glasses support retinal prosthesis

The Johns Hopkins Applied Physics Lab and Second Sight are developing  glasses with embedded vision and eye tracking sensors to be used with a  new retinal prosthesis system.  The system will identify obstacles, doorways, hallways, and household objects and their relative positions. The information will be projected into the retinal prosthesis, bypassing the damaged rods and cones […]

Carbon nanotube artificial retina restores light sensitivity

Tel Aviv University, The Hebrew University of Jerusalem and Newcastle University researchers are developing an artificial retina that sends sensory signals to the brain to address vision loss.  Several groups are attempting this, but have had issues with metallic parts, cumbersome wiring, or a low resolution outcome. The TAU, HUJI and Newcastle team is working on […]

Bluetooth headset guides the visually impaired

Microsoft is collaborating with Guide Dogs for the Blind and AfterShokz on Cities Unlocked, a prototype headset, smartphone and navigation system for the visually impaired. The technology helps a user find his/her way, describes potential hazards, such as low-hanging trees, and highlights attractions, including restaurants, on the route. The headset uses bone-conducting audio that does not […]

More realistic virtual reality — Google hopes

Little is known about MagicLeap, recently backed by Google, representing an assumed commitment to the gaming space, with potential BCI applications.  Patent applications suggest that the company provides display technology that can trick the human visual system better than existing virtual reality displays. Reports discuss an improved virtual reality user interface that lets one’s eyes focus on […]

Google/Novartis “smart lens” monitors diabetic eyes, helps presbyopia

Google announced its “smart lens” prototype 6 months ago.  (See ApplySci,  January 14 2014).  Today they have partnered with Novartis to accelerate its development as a tool to manage eye conditions. Non-invasive sensors and microchips embedded in the lens monitor fluid to provide continuous, minimally invasive glucose measurement. The data is sent wirelessly to a […]

Kinect/Android system guides the visually impaired

Students at the Technion – Israel Institute of Technology have created a system for the visually impaired that detects  obstacles and uses audio messages and signals to alert users before a collision.The “seeing app,” developed by Tzahi Simkin, Gal Dalal and Danny Zilber, uses a Kinect 3D camera, a computer and an Android phone for audio interaction.  They […]

Ultrasound improves virtual “touch”

Ultrahaptics uses ultrasound waves to make one feel as if he/she is  touching virtual objects and surfaces with bare hands. It’s creator, a University of Bristol graduate student, claims that it improves upon touch-free interfaces such as Kinect and Leap Motion by reflecting air pressure waves off the hand to create different sensations for each fingertip. Applications could include interacting with moving […]
