One of the most beautiful of the iPad, and IOS devices in general, is that they are ready to be tested in any way! Here then begin to rise projects like the one we will discuss now called Air Touches.
Carried out by the developer Greg Hartstein, Air Touches sees an iPad 2 working similarly to a Kinect. All of this happens naturally through the rooms of the Apple device, which initially were used in a completely dark room and could simply measure the distance of the object from iPad according to light levels.
Now, after a while ‘time of testing, things have evolved and, thanks to a video posted on YouTube below by the developer, we are aware of the fact that, through a narrow object in his hand used for tracking, all is simplified compared to the early days and no longer requires such strict environmental conditions.
Unfortunately the video is not of the highest quality, but you can understand how things are progressing and how to create the Air Touches seems to work.
At present work, however, in addition to the detection of distance and rotation, Hartstein has worked on-air swipes and other gestures that would be nice to use without having to be forced to touch the screen.
