A new gesture capture system has been created that allows you to wave your hands in front of a computer screen to control objects on the screen. This new system is still in early stages, but a big step up here is that it requires no gloves to control it.
The system works by using a Bi-Directional screen called BiDi that has a screen and behind it that shows a pinhole array pattern. The backlight is alternated with the image allowing the screen to show an image as well as capture what is in front of the screen. By using optical sensors behind the glass a hand can be captured and gestures calculated without the user needing to touch the screen.
Although still in early days it has great potential in my opinion. If hand movements can be detected without the need to touch the screen it opens up a lot of possibilities for interacting with a computer.
Check out the video below that shows the screen in action. The video shows a user manipulating objects on screen by zooming, rotating etc… About 3/4 of the way in to the video you will see a bar on the left side of the screen that represents distance from the screen. It’s very interesting stuff and well worth watching.
