1. A user interface for use with a computer, comprising:
- an at least partially transparent roller; and
a sensor system, associated with the transparent roller, operable in a first mode to sense the image of a fingerprint and operable in a second mode to sense the rotational motion of the roller.

Abstract
A user interface including an at least partially transparent roller. The transparency allows the roller to be used as part of a fingerprint scanning system during fingerprint scans. The roller may also be used for other purposes during non-scanning periods. For example, the roller may be used in place of a conventional scroll key to control scrolling.

9. A user interface for use with a computer, comprising:
-
an at least partially transparent roller;
a light source that emits light which passes through the roller;
a light sensor that receives reflected light;
a rotational motion sensor associated with the roller that senses rotational motion of the roller; and
a control system, associated with the light source, light sensor and rotational motion sensor, the control system being operable in a first mode to enable operation of the light source, light sensor and rotation motion sensor and operable in a second mode to enable operation of the rotation motion sensor and disable operation of at least one of the light source and at least a portion of the light sensor. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A computer system, comprising:
-
a user interface including an at least partially transparent roller;
an image sensor associated with the roller that senses the image of a fingerprint and generates fingerprint image data;
a rotational motion sensor associated with the roller that senses rotational motion of the roller and generates roller motion data; and
a control system associated with the image sensor and rotational motion sensor, the control system being operable in a first mode to convert the fingerprint image data and rotational motion data into data representative of the scanned fingerprint and operable in second mode to control an operation of the computer system in response to the roller motion data. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method of operating a computer system including an at least partially transparent roller, the method comprising the steps of:
-
receiving data corresponding to rotational motion of the roller;
using the data corresponding to rotational motion of the roller to generate data corresponding to a fingerprint when the computer system is in a fingerprint scanning mode; and
using the rotational motion of the roller to control a predetermined aspect of computer system operation when the computer system is not in the fingerprint scanning mode. - View Dependent Claims (28, 29)
