Input writing device
First Claim
1. An input device comprising:
- an elongated housing;
a cap removably carried on said housing;
a surface motion sensor carried in said housing and adapted to sense motion of one end of said housing relative to a surface when said cover is removed; and
wherein said cap is adapted to enclose at least a portion of said housing when said cap is carried thereon and enables manual activation of the motion sensor through the cap carried on said housing to at least partially cover said motion sensor adapted to sense motion through a transparent portion of said cap when said cap is coupled to said housing.

Abstract
A writing stylus (100) having a motion sensor (204) for sensing the movement of at least one end 110 of the stylus relative to an adjacent surface is described. The stylus has an elongated housing (104) and a cap (102). The motion sensor generates signals corresponding to the relative motion of the surface to the sensor. The cap is removeably carried on at least one portion of the housing which also has the motion sensor. The cap comprises a light passage (118) adapted to allow the motion sensor to sense the translation of the surface adjacent to the cap, through the cap. In a first input mode the motion sensor is used for sensing manual hand writing motion. In a second mode, when the cap is carried on the housing and is placed over at least the motion sensor, the motion sensor senses the motion of a surface adjacent to the cap such as a users finger. In this mode, the stylus functions a multiple axis input device such as a thumbwheel.

27. A method in a virtual pen device having an interferometer motion sensor and a pen cap, comprising the steps of:
-
placing a cap having a transparent portion over a laser interferometer portion of said pen;
selecting a finger input mode;
sensing the motion of a surface relative to said cap in at least a first axis and a second axis; and
sending motion signals in response to sensing said motion of said surface to control operations on a terminal device. - View Dependent Claims (28, 29, 30)
