Abstract
An optical pointing device comprising an optical navigation sensor and an adjustment module for adjusting an operational height of the optical navigation sensor is provided in one embodiment. In another embodiment, an optical pointing device comprising a housing and an optical navigation sensor contained in the housing is provided where the optical navigation sensor is configured to provide movement information to a processing system to cause a pointer to continue moving in response to detecting that the housing has been lifted from a navigation surface.
Claims24
An optical pointing device comprising:
- an optical navigation system;
- and
- an adjustment module for adjusting an operational height of the optical navigation system.
A method performed by an optical navigation sensor in an optical pointing device, the method comprising:
- receiving a navigation parameter;
- and
- adjusting an operational height of the optical pointing device using the navigation parameter.
A program product executable by a processing system for causing the processing system to:
- receive a calibration selection from a user;
- prompt the user to adjust an optical navigation device coupled to the processing system;
- perform a calibration to generate at least one navigation parameter configured to adjust an operation height of the optical navigation device;
- and
- provide the navigation parameter to the optical navigation device.
A method performed by an optical navigation sensor, the method comprising:
- detecting a lift between an optical pointing device that includes the optical navigation sensor and a navigation surface;
- and
- providing movement information to a processing system to cause a pointer to continue moving in response to detecting the lift.
An optical pointing device comprising:
- a housing;
- and
- an optical navigation sensor contained in the housing;
- wherein the optical navigation sensor is configured to provide movement information to a processing system to cause a pointer to continue moving in response to detecting that the housing has been lifted from a navigation surface.
