US 7,990,365 B2 · Motion controlled remote controller

Abstract

A handheld device includes a display having a viewable surface and operable to generate an image indicating a currently controlled remote device and a gesture database maintaining a plurality of remote command gestures. Each remote command gesture is defined by a motion of the device with respect to a first position of the handheld device. The device includes a gesture mapping database comprising a mapping of each of the remote command gestures to an associated command for controlling operation of the remote device and a motion detection module operable to detect motion of the handheld device within three dimensions and to identify components of the motion in relation to the viewable surface. The device includes a control module operable to track movement of the handheld device using the motion detection module, to compare the tracked movement against the remote command gestures to determine a matching gesture, and to identify the one of the commands corresponding to the matching gesture. The device also includes a wireless interface operable to transmit the identified command to a remote receiver for delivery to the remote device.

Dependent claims

A motion controlled handheld device, comprising:

a first accelerometer operable to detect acceleration along a first axis;
a second accelerometer operable to detect acceleration along a second axis, the second axis perpendicular to the first axis;
a tilt detection component operable to detect rotation having a component around at least one of the first axis and the second axis, the tilt detection component comprising:
a first camera operable to generate a first video stream;
a video analysis module operable to detect a direction of motion based on the first video stream;
a range finder operable to determine distance information including a distance between the device and an object in the first video stream, wherein the video analysis module is further operable to determine a magnitude of translation of the device using the distance;
a display operable to present a current image;
a motion tracking module operable to track motion of the device in three dimensions using the first accelerometer, the second accelerometer, and the tilt detection component;
and
