1. A handheld electronic device having user interface, the handheld device comprising:
- (a) a sensor that generates information associated with an environmental condition for the handheld electronic device, changes in the environmental condition resulting, at least in part, based on movement of the handheld device relative to the environment;
(b) a controller that processes the data generated by the sensor (c) a computer program executable by the controller for;
tracking movement of the handheld device in three-dimensional free space according to the data generated by the sensor;
translating the tracked movement of the device to a corresponding movement of digital content; and
displaying the corresponding movement in digital content via the user interface.

Abstract
A gestural input system provides an intuitive man-machine interface that converts human locomotion in free space, independent of fiducials and references surfaces to data that may be processed by a controller. A gestural input translates movement of a human and/or manipulation of a device in free space to data or signals for navigating digital content such as a 2D or 3D virtual or augmented reality.

20. A gestural input device, comprising:
-
a camera configured to capture a sequence of picture frames of a field of view of the camera;
means for tracking features captured in the picture frames;
means for converting tracked features captured in the picture frames to movement of the input device; and
means for translating movement of the input device to movement in digital content. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)

28. A computer-readable medium having computer-executable instructions stored therein, the computer-executable instructions causing a controller to execute:
-
receiving data representative of changes in environmental conditions affected by a motion of the controller in free space in the environment;
identifying the motion of the controller according to the data; and
translating the motion of the controller to an instruction to be executed by the controller. - View Dependent Claims (29, 30)
