Swiss researchers have developed a haptic technology that they claim will pave the way for a new generation of touch screens. The technology developed at the École Polytechnique Fédérale de Lausanne (EPFL) uses a vibrating material to create the feeling of raised keys under your finger. The vibrations, caused by voltage changes, are imperceptible to human touch but do create relief effects on a surface. “The term ‘touch screen’ that’s used to describe current technology is really a misnomer, because they only provide visual and auditory feedback,” said Christophe Winter, a PhD student at the EPFL. Winter is part of the team at the organisation’s Integrated Actuators Laboratory (LAI) that developed the technology that can control the texture of screens. “We’re adding the sense of touch to tactile surfaces,” he adds. Researches say this added layer of information will improve usability of touch display and improve user experience. Furthermore it has massive implications on how visually impaired people can interact with touchscreens. Screen Shot On Link Video, Source: InAVate
