An App To Help ALS Patients To Communicate With Their Eye Gestures

Scientists, including one of Indian origin, have developed a low-cost smartphone app that allows people with ALS and other motor impairments to easily communicate with eye gestures in real time. For people with amyotrophic lateral sclerosis (ALS) or other motor impairments, the current eye-tracking input systems are expensive, not robust under sunlight, and require frequent re-calibration and substantial, relatively immobile setups, said researchers. Eye-gaze transfer (e-tran) boards, a low-tech alternative, are challenging to master and offer slow communication rates. To mitigate the drawbacks of these two status quo approaches, researchers including Harish Kulkarni from Microsoft Research and Xiaoyi Zhang from University of Washington in the US, created GazeSpeak. GazeSpeak can interpret eye gestures in real time, decode these gestures into predicted utterances and facilitate communication, with different user interfaces for speakers and interpreters.
