Touchscreen to feel like keyboard
Sunday, February 15, 2015
New research could allow your touchscreen keyboard to
actually feel like a keyboard, scientists say.
Northwestern University and Carnegie Mellon University
researchers have made discoveries that could bring
texture to your flat touchscreen.
The researchers said their new mathematical model and
experimental results on "haptic illusions" could one day
lead to flat-screen displays featuring active touch-back
technology, such as making your touchscreen's keyboard
actually feel like a keyboard.
Tactile information also could benefit the blind, users
of dashboard technology in cars and players of video
games. Forces felt by the fingers as they travel along a
flat surface can lead to the illusion that the surface
actually contains bumps. This so-called "virtual bump
illusion" is well known in the haptics field, said J
Edward Colgate at Northwestern's McCormick School of
Engineering and Applied Science.
