Abstract
Input devices and methods are provided in which a sensing system is adapted to detect motion of an object on a surface and a processing system is coupled to the sensing system. The processing system is adapted to effect movement of a display pointer on a display in a first direction in response to motion of the object on the surface and effect continued movement of the display pointer in the first direction in response to the object being removed from the surface.
Claims30
An input device comprising:
- a sensing system adapted to detect motion of an object on a surface;
- and
- a processing system coupled to the sensing system, the processing system adapted to:
- effect movement of a display pointer on a display in a first direction in response to motion of the object on the surface;
- effect continued movement of the display pointer in the first direction in response to the object being removed from the surface;
- and
- effect movement of the display pointer in a second direction on the display in response to the display pointer reaching an edge portion of the display during the continued movement in the first direction, the second direction being different from the first direction.
4 more elements
A method comprising:
- effecting movement of a display pointer on a display in a first direction towards an edge portion of the display in response to detecting motion of an object on a surface;
- effecting continued movement of the display pointer in the first direction in response to detecting the object leaving the surface if the object is moving during a selected time period before the object leaves the surface;
- and
- effecting continued movement of the display pointer in a second direction on the display away from the edge portion of the display in response to the display pointer reaching the edge portion of the display during the continued movement in the first direction.
1 more element
A program product comprising:
- an input device program adapted to:
- detect motion of an object on a surface of an input device;
- effect movement of a display pointer on a display in a first direction towards an edge portion of the display in response to motion of the object on the surface;
- effect continued movement of the display pointer in the first direction in response to the object being removed from the surface within a selected time period of the motion of the object on the surface;
- and
- effect movement of the display pointer in a second direction on the display away from the edge portion of the display in response to the display pointer reaching the edge portion of the display during the continued movement in the first direction, the second direction being different from the first direction;
- and
- computer-readable media bearing the input device program.
5 more elements
A user input device comprising:
- a housing;
- at least one sensor coupled to the housing and adapted to detect motion of the housing relative to a surface;
- and
- a processing system coupled to the at least one sensor, the processing system adapted to:
- effect movement of a display pointer on a display in response to motion of the housing across the surface;
- and
- effect continued movement of the display pointer in response to a decreased proximity of the housing with the surface.
4 more elements
A method comprising:
- effecting movement of a display pointer across a display in response to motion of a mouse device across a surface;
- and
- effecting continued movement of the display pointer in response to a decreased proximity of the mouse device with the surface if the mouse device is moving across the surface during a selected time period before the decrease in the proximity of the mouse device with the surface.
