Abstract
An input device that transmits, to a host device having a display displaying a pointer, information relating to the pointer and includes a sensor detecting contact information, and further includes an area extracting part and a control part. The area extracting part extracts a contact area of the sensor and a finger based on the contact information detected by the sensor. The control part controls the pointer based on the contact area extracted by the area extracting part.
Claims18
An input device that transmits, to a host device having a display displaying a pointer, information relating to the pointer and includes a sensor detecting contact information, comprising:
- an area extracting part extracting a contact area of the sensor and a finger based on the contact information detected by the sensor;
- and
- a control part controlling the pointer based on the contact area extracted by said area extracting part.
A pointer control method of controlling a pointer displayed on a display of a host device based on contact information detected by a sensor, comprising the steps of:
- (a) extracting a contact area of the sensor and a finger;
- and
- (b) controlling the pointer based on the contact area extracted in step (a).
An input device that transmits, to a host device having a display displaying a pointer, information relating to the pointer and includes a sensor detecting contact information, comprising:
- a fingerprint authentication part authenticating a fingerprint of a finger touching the sensor;
- an area detecting part detecting the size of a contact area of the sensor and the finger based on the contact information detected by the sensor;
- and
- a control part controlling a moving speed of the pointer based on the fingerprint authenticated by said fingerprint authentication part and the size of the contact area detected by said area detecting part.
