A silver nanowires-based flexible capacitive touch screen in tactile displays for individuals with visual impairment using gesture recognition (Conference Presentation)

Tactile displays are very popular among visually disabled and blind people for haptic reading and accessing graphs. Navigating through a haptic display would be easier through touch instead of buttons. Therefore, a touch screen is a necessity particularly when dealing with graphics. We developed a flexible capacitive touch screen based on silver nanowires (AgNWs) on a polyimide (PI) substrate with a total thickness of 210 µm. To classify eight hand gestures, we have implemented a hand gesture recognition application using deep learning and achieved an accuracy of 97% acquired from 300 measurements per gesture.
