This was something we were hoping Nokia would bring out themselves. Here’s Microsoft’s take on it, using piezoelectric actuators and electrostatic haptics technology to ‘feel’ the keys on the screen.
In the mean time, you know I wouldn’t mind the old classic Nokia ‘vibrate’ haptic pressing on keys. They may be generic but better than nothing and would be nice as an option.
With haptic feedback, MS found that people type faster and make less errors.
Not only are they demonstrating button ‘clicks’ but textures. They say that in this 920 demo, the black parts feel sticky. By vibrating the glass at certain frequencies, air can be trapped which supposedly makes the screen smoother.
