Allowing the user to feel the texture from images as the finger moves across the touch surface is a unique aspect of the new generation of touchscreen technology developed by researchers at the Indian Institute of Technology, Madras
While existing touchscreens can only sense the location of finger touch, the new technology will allow a new level of interaction on smooth physical surfaces enabling the creation of textures that range from crisp edges, switches, and rich textures t…
Called ‘iTad’ for interactive Touch active display, the researchers say it is the next generation in touch display technology as it allows them to create different textures such as crisp edges, switches, and rich textures that range from smooth to gr…
There are no moving parts in iTad. Instead, an in-built multi-touch sensor detects the movement of the finger, and surface friction is adjusted via software. By controlling electric fields via a physical phenomenon known as ‘electroadhesion,’ the sof…
