User input device
First Claim
1. A user input device comprising:
- a body portion extending from a first side portion to a second side portion, the body portion movable between a first position and a second position;
a plurality of keys representing a plurality of characters arranged on the body portion between the first and second side portions;
a motion tracking element on the body portion for moving a display image, the motion tracking element operable as a first mode of input when the body is in the first position and operable as a second mode of input when the body is in the second position, wherein the second mode of the motion tracking element comprises a digital pen; and
a transmitter on the body portion for electromagnetically transmitting data away from the body portion.

Abstract
A user input device has a body portion extending from a first end to a second end and having a plurality of keys, for example keys that may be arranged and configured to be a keyboard, and an optical motion element. A wireless transmitter transmits data entered through the keys to a target component, for example a computer, a PDA, a digital watch, and the like. The user input device may include a hinged panel having some of the keys, and when the hinged panel is in an open configuration, the arrangement of the keys may be similar to an alphanumeric keyboard. The optical motion element may be an optical mouse for controlling a cursor on a display, when the hinged panel is open. When the hinged panel is closed the optical motion element may be configured to serve as a digital pen, for sensing natural writing, pen motions used to control a display, such as cursor location or to make selections on a menu, for example. The device may be sized so as to be easily portable, fit inside a pocket, and may be formed to have a shape similar to a writing instrument.

26. A process for controlling an image on a display, the process comprising the steps of:
-
placing a housing within reach of a hand for manipulation of at least one key on the housing, the housing being movable between an open position and a closed position; moving a finger within the field of view of an optical motion element in the housing with the housing in the open position and detecting the magnitude and direction of movement of the finger relative to the optical motion element; moving the housing along a surface with the housing in the closed position and detecting movement of the housing along the surface through the optical motion element; and transmitting from the housing to a receiver electromagnetic signals representing the magnitude and direction of at least one of movement of the finger and movement of the housing. - View Dependent Claims (27, 28)

29. A system for controlling an image on a display, the system comprising:
a user input device having a body portion movable between a first position and a second position, manual input keys for receiving manual input from a user, a motion tracking element on the body portion operable as a first mode of input when the body is in the first position and operable as a second mode of input when the body is in the second position, wherein the second mode of the motion tracking element comprises a digital pen, and a transmitter coupled to the input keys and to the motion tracking element for transmitting signals; and
a display coupled to a receiver for receiving, signals from the transmitter.- View Dependent Claims (30, 31, 32, 33)
