If there's one downside to the proliferation of touchscreen technology, it's the lack of tactile feedback. Tactus is one of many companies that aims to alleviate this problem. This week, at SID 2012, the company demoed a product that offers disappearing physical touch keys. As seen in the demo video here, these buttons can raise on command and disappear when they're not needed. Which sounds like something out of science fiction.
At the moment, the display can only be configured for preset layouts. Meaning, you configure it for a landscape QWERTY layout, that's all you'll get. No gaming controls, no dialer configurations.
