ViviTouch haptic technology hands-on: electroactive polymer giving a 'high definition
Haptic feedback isn't exactly something that'd blow people's mind these days, with most mobile devices and gaming controllers already packing a little vibrator to spice up one's gaming experience. While these motors do the job just fine for delivering the sensation of large engines and explosions, their monotonic performance and relatively high minimum output threshold means they can't reproduce finer vibration. For instance, you wouldn't be able to feel a guitar string fade away after a strum, nor would you feel the finer end of a spring recoil. This is where Bayer MaterialScience's ViviTouch -- previously dubbed Reflex -- tries to fill the void.
