Sony has opened API Floating touch

Floating touch, or “floating touch,” is a technology that allows you to control a touch screen without directly touching the display.

This Sony development was first introduced this spring on the Xperia Sola smartphone, and with a recent update it became more efficient by acquiring another useful skill called glove mode - now the Sola screen can be controlled even when wearing gloves. Destructive feature on the eve of winter.

As for the “soaring touch”, it is still not enough to enjoy it in full, rather narrow possibilities for use, limited to highlighting the links in the smartphone’s native browser. However, now this situation has to change - along with the latest Ice Cream Sandwich update for Xperia sola, the API Floating touch became available - and each developer will be able to use the contactless control capabilities in his application. It will be very interesting to see what happens.

Learn more about this with code examples - in the Floating Touch API tutorial from Andreas Sandblad, software architect Sony.

In the comments, I propose to fantasize about which floating touch applications can be applied with the greatest benefit.
