Abstract

A 3D pointing device includes a keyboard for character entry. In pointing mode, data from at least one motion sensor is provided, e.g., to be transmitted to a user interface for movement of a cursor. In text entry mode, data from at least one depressed key is provided, e.g., to be transmitted to a user interface for display thereon.

Claims

1. A 3D pointing device whose 3D pointing determines a position of a cursor displayed on a remote user interface, comprising:

a housing;

at least one inertial sensor mounted within said housing and configured to detect motion of said 3D pointing device and to output motion data associated therewith, wherein the at least one inertial sensor includes at least one rotational sensor configured to detect rotational motion of the 3D pointing device about at least two axes and at least one accelerometer configured to detect acceleration about at least three axes,

wherein said motion data includes outputs of the at least one inertial sensor and the at least one accelerometer;

a processing unit configured to receive and process said motion data configured to output values associated with said motion of said 3D pointing device;

a keyboard including a first set of keys disposed on said housing and configured to enable text input to said processing unit;

a scroll wheel disposed on said housing and configured to enable scroll input to said processing unit;

at least one button disposed on said housing and configured to enable input associated with pointing; and

a transmitter configured to transmit said output values associated with said motion of said 3D pointing device and said text input received from said processing unit, from said 3D pointing device towards said remote user interface,

further wherein said 3D pointing device is configured to switch between a 3D pointing mode and a text entry mode wherein movement of the 3D pointing device corresponds to cursor movement on said remote user interface, wherein by pointing to an icon displayed on said remote user interface and selecting said icon, said remote user interface changes to said text entry mode and disregards any further movement of the 3D pointing device.

2. The 3D pointing device of claim 1, wherein said keyboard is a QWERTY keyboard.

3. The 3D pointing device of claim 1, wherein said keyboard is a non-QWERTY keyboard.

4. The 3D pointing device of claim 1, wherein said at least one sensor includes a gyroscope.

5. The 3D pointing device of claim 1, wherein said processing unit processes said motion data to compensate for tilt of said 3D pointing device to output said values.
