US Patent:

6809723, Oct 26, 2004

Filed:

May 14, 2001

Appl. No.:

09/855013

Inventors:

Jeffery Davis - Mountain View CA

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G09G 508

US Classification:

345166, 345160, 345165

Abstract:

An apparatus for controlling the position of a screen pointer for an electronic device having a display screen includes a pushbutton for selecting an item displayed on the display screen. The pushbutton includes an imaging surface against which a portion of the tip of a human digit may be placed. A light source illuminates that portion of the tip of the digit that is placed against the imaging surface, thereby generating reflected images. The apparatus includes a motion transducer. A lens receives the reflected images and directs the reflected images onto the motion transducer. The motion transducer generates digital representations of the reflected images. The motion transducer generates a first set of movement data based on the digital representations of the reflected images. The first set of movement data is indicative of motion of the tip of the digit across the imaging surface.

Appl. No.:

09/812754

Inventors:

Jeffery Davis - Mountain View CA, US
Michael John Brosnan - Fremont CA, US

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G09G005/00

US Classification:

345684

Abstract:

A method of scrolling through information displayed on a display screen of an electronic device includes providing a first plurality of user selectable scrolling zones on the display screen. Each scrolling zone in the first plurality of scrolling zones is associated with a scrolling technique. The display screen includes a screen pointer controllable by a user with a screen pointing device. Zone selection information identifying a first one of the scrolling zones selected by a user with the screen pointing device is received. The displayed information is scrolled through based on the scrolling technique associated with the selected scrolling zone.

International Classification:

G09G 5/08

US Classification:

345166

Abstract:

An apparatus for controlling the position of a screen pointer for an electronic device having a display screen includes a light source for illuminating an imaging surface, thereby generating reflected images. The apparatus includes a single chip for receiving the reflected images, generating digital representations of the reflected images, and generating a first set of movement data based on the digital representations of the reflected images. The first set of movement data is indicative of relative motion between the chip and the imaging surface. The single chip includes a serial interface for outputting motion data in a serial format based on the movement data.
