Abstract
An input device provides tactile feedback to its user. The input device includes a rotatable control wheel that provides an input signal to a host device, and further includes a control wheel limiter structured to, in response to a received position signal, limit rotatability of the control wheel.
Claims30
An input device structured to provide tactile feedback to a user of the input device, comprising:
- a rotatable control wheel structured to provide an input signal to a host device;
- and
- a control wheel limiter structured to, in response to a position signal from the host device, limit rotatability of the control wheel.
An input device structured to provide tactile feedback to a user of the input device, comprising:
- an input device frame having a frame aperture;
- a rotatable control wheel structured to provide an input signal to a host device, the control wheel mounted to the device frame and protruding sufficiently through the frame aperture to allow it to be rotated by such user;
- a position signal receiver operative to receive a position signal corresponding to a scroll value in a document displayed on the host device;
- and
- a control wheel limiter structured to, in response to a received position signal, limit rotatability of the control wheel.
2 more elements
A method for providing tactile feedback to a user of an input device scroll wheel, comprising:
- determining if a document displayed in a viewing window of a host device is at one of two end positions within the viewing window;
- and
- limiting rotation of the scroll wheel in at least a first direction if the document is at one of the end positions.
