User control input device

摘要

An optical input card is shaped and sized for removable slidable insertion within a slot of a portable computer. The optical input card comprises an optical navigation sensor, a control panel and a wireless communication module. The optical navigation sensor is disposed on the first side of the card for exposure to a navigation surface and is configured to capture a first user control input. The control panel on a second side of the card is configured to capture at least one second user control input. The wireless communication module is configured to wirelessly communicate the first user control input and the at least one second user control input to the portable computer.

1. An input device comprising:
a mouse shell configured to support a spherical member that is rotatably coupled to the mouse shell so that user can manually rotate the spherical member, the mouse shell including:
a wireless communication module;a control panel configured to capture a first user control input for controlling at least one function of a computing device via the wireless communication module; anda slot sized and shaped for slidable removable insertion of an optical navigation card including an optical navigation sensor into the slot of the mouse shell to position the optical navigation card such that a surface of the spherical member attached to the mouse shell is exposed to the optical navigation sensor of the optical navigation card when the optical navigation card is inserted into the slot for detection of relative motion between the optical navigation card and the surface of the spherical member to capture a second user control input for controlling the at least one function of the computing device via the wireless communication module, the optical navigation card being configured such that the surface of the spherical member is optically imaged by the optical navigation sensor as the surface of the spherical member is rotated relative to the optical navigation sensor to capture the second user control input.
