Smartphone nderstands Gestures
The gesture control program recognizes six different gestures and executes their corresponding commands.

ETH Zurich researchers have developed an app that enables users to use hand gestures to operate their smartphones. The app is based on an algorithm developed by the researchers that uses a smartphone's built-in camera to register its environment. The app registers the shape of hand gestures and the parts of the hand to receive commands. The program then executes the command associated with the gestures it observes. The program also can recognize the hand's distance from the camera and warn users if their hand is too close or too far away.
ETH Zurich professor Otmar Hilliges says the app's minimal processing footprint means it also could be used in smart watches or in augmented-reality glasses. The program currently recognizes six different gestures and executes their corresponding commands. "To expand its functionality, we're going to add further classification schemes to the program," Hilliges says.
The researchers aim to keep the gestures as simple as possible to make operating the devices easier for users.
