Abstract
Systems, devices, methods, and non-transitory computer-readable media are provided for receiving data input via touch-free gestures and movements. For example, a data input device includes at least one processor for receiving information from a sensor. The processor may be configured to receive sensor data from the sensor of a user's hand spaced a distance from a displayed keyboard and in non-contact with the displayed keyboard, and track, using the received sensor data, one or more fingers in air a distance from the displayed keyboard image. The processor may also be configured to correlate locations of the one or more fingers in the air with images of a plurality of keys in the displayed keyboard, and select keys from the keyboard image based on the correlated locations of the one or more fingers in the air, and a detection of a predefined gesture performed by the user.
