Fingertip mouse and base

摘要

The subject matter of this specification can be embodied in, among other things, a system that includes a tracking device to generate movement information for use in moving a user interface object on a graphical user interface. The tracking device is configured to receive at least a portion of a user's finger. The system also includes a base device configured to receive the tracking device. The base device is configured to translate movement of the base device relative to an adjacent surface for use in moving the user interface object.

主权项

1. A wireless finger-worn motion tracking device comprising:
a housing configured to be worn on a finger of a user, the housing having a passage therethrough, the passage defining a passage axis generally coaxial with a longitudinal axis of the user's finger when the user's finger is extending through the passage of the housing in a finger-worn position, the housing including an internal finger contact surface that is facing generally radially inward toward the passage axis, the internal finger contact surface making contact with the user's finger when in the finger-worn position, the housing passage and internal finger contact surface configured such that an end portion of the user's finger can be extended through the passage entirely to the finger-worn position such that the end portion of the user's finger is out of contact with the internal finger contact surface in the finger-worn position, the housing further including an external outside surface that is facing generally radially outward from the passage axis, the external outside surface being not in contact with the user's finger when in the finger-worn position, the housing further including an inner space between the internal finger contact surface and the external outside surface, wherein the inner space is configured to contain all electronics for operating the wireless finger-worn motion tracking device; wireless communication components disposed within the inner space, the wireless communication components configured and operable to wirelessly communicate with a separate computing system; a motion tracking mechanism disposed within the inner space and configured and operable to generate, in response to movements of the housing, tracked movement information for use in controlling the separate computing system, the motion tracking mechanism comprising an accelerometer; a selection mechanism coupled to the housing and configured and operable to generate, in response to an activation of the selection mechanism, selection information for use in controlling the separate computing system; and a display device located on the housing, wherein the display device is configured and operable to output information.
