Some commentary on several examples of forthcoming 'touch' sensitive technologies.
M$ continue to develop vision systems for 'augmented reality' – "Most augmented-reality systems must be able to orient themselves accurately in order to function reliably. Some locate their position using GPS or by triangulating several Wi-Fi signals, and determine which way they are pointing using an accelerometer and a digital compass. Microsoft's augmented-reality device focuses on being able to recognize objects within a scene, using sophisticated computer-vision algorithms. Since the demonstration is carried out in the controlled environment of the conference hall, the researchers are not using location-detecting sensors; instead, they're relying solely on computer vision."
