The Novint Falcon lets you control a game in three dimensions, and also lets you feel high-fidelity three-dimensional force feedback. The Falcon controller moves right and left, forwards and backwards, like a mouse, but also moves up and down. When you hold the Falcon’s detachable Grip and move your cursor to interact with a virtual object, environment, or character, motors in the device turn on and are updated approximately 1000 times a second, letting you feel texture, shape, weight, dimension, and dynamics. The Falcon lets you control and interact with games in more realistic way, allowing you to develop real physical skill and muscle memory, adding a new dimension to gaming.

There’s no more natural control interface than yourself. This robot, developed by engineer Tsuyoshi Horo at Tokyo University, watches you with an array of eight cameras and creates a 3D model of your body. If you point your finger, the cameras will recognize the shape, and send commands to the robot to respond to your gesture. It’s way cool, but it’s not exactly portable, since the cameras are stationary. It’s able to do all kinds of things besides robot control; here’s a video of someone playing Half-Life 2 with body motions:

Eyebox 2 uses a design that allows the camera to automatically detect when you are looking at it from up to 10 meters, without calibration.

Oliver Irschitz has created the iTube. In the iTube, participants use natural interfaces to explore the virtual 3D spaces projected onto its large screen with a small set of pointing and command gestures. A robust computer-vision-based, full-body immersive interface empowers surfing inside the cityscape. A separate computer-vision-based hand-tracking and gesture-recognition system drives navigation inside the BrainSpace. These interfaces work in real time and require only standard computers and small cameras. They do not require special calibration procedures, do not limit body movements with cables or tethers, nor do they require wearing special suits with markers for tracking.

Joa Ebert and Thibault Imbert have created the framework to control flash animations using the Wiimote. You can download this software from their website. It is becoming possible to control flash movies through gesture.

Researchers at Prime Sense have created the ability to navigate using hand gestures in midair. Prime Sense’s concept is a device, which allows a computer to perceive the world in 3D and derive an understanding of the world based on sight, just the way humans do.

The device includes a sensor, which sees a user (including their complete surroundings), and a digital component, or “brain” which learns and understands user movement within those surroundings.

Prime Sense’s interactive device can see, track and react to user movements outside the computer, all without change of environment or wearable equipment for the end user. The closed device is plug and play and platform independent.
