Abstract
Abstract A manipulandum contained in a portable housing unit adapted for grasping by hand and situated at one end thereof within an area reachable by the thumb without rearranging the grasp. In one preferred embodiment, the manipulandum is a joystick extending a short distance from the surface of the housing, with its center of neutral position being essentially perpendicular to the center line of the elongated segment in the neighborhood of the joystick. The joystick has a fixed number of positions, with each position being contained within a preselected solid angle. An additional control dimension is realized by moving the joystick along its axis, against a resilient spring, so as to activate or make contact with an electrical switch.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
75 words
A hand-held device comprising: an elongated segment adapted for grasping by hand; and a pivotable joystick situated toward one end of said elongated segment and protruding from said elongated segment, having a neutral position that is generally perpendicular to a center line of said elongated segment in the neighborhood of said joystick, said joystick being movable to all of its pivotable positions by the face of the thumb of a hand grasping said elongated segment.
Claim 2
Dependent Claim
75 words
A hand-held device comprising: an elongated segment adapted for grasping by hand; and a pivotable joystick situated toward one end of said elongated segment and protruding from said elongated segment, having a neutral position that is generally perpendicular to a center line of said elongated segment in the neighborhood of said joystick, said joystick being movable to all of its pivotable positions by the face of the thumb of a hand grasping said elongated segment.
Claim 3
Dependent Claim
27 words
The hand-held device of claim 1, further comprising a display element displaying N lines of text, with said joystick possessing at least 2N+1 electrically identifiable distinct positions.
Claim 4
Dependent Claim
29 words
The device of claim 1 wherein said joystick is moveable generally in an axial direction to activate an electrical switch regardless of position to which said joystick is pivoted.
Claim 5
Dependent Claim
54 words
A hand-held device comprising: an elongated segment adapted for grasping; and a multi-position manipulandum protruding from a surface that is generally parallel to a centerline of said elongated segment and within reach of the thumb of a hand grasping said elongated segment and extended generally parallel to the center line of said elongated segment.
Claim 6
Dependent Claim
54 words
A hand-held device comprising: an elongated segment adapted for grasping; and a multi-position manipulandum protruding from a surface that is generally parallel to a centerline of said elongated segment and within reach of the thumb of a hand grasping said elongated segment and extended generally parallel to the center line of said elongated segment.
Claim 7
Dependent Claim
26 words
The device of claim 4 wherein said joystick is movable within a hemisphere and has a countable plurality of positions delineated by regions within said hemisphere.
Claim 8
Dependent Claim
44 words
The device of claim 4 wherein said joystick is movable generally along its axis regardless of position to which said joystick is pivoted and further comprising resilient means that, in the absence of applied pressure, maintains said joystick at one of its colinear positions.
Claim 9
Dependent Claim
16 words
The device of claim 5, further comprising a display segment that displays N lines of text.
Claim 10
Dependent Claim
60 words
The device of claim 7 wherein said joystick has N positions that may be reached by moving said joystick to a first side, and N positions that may be reached by moving said joystick to a second side, where said first and second sides are regions separated by a plane containing said joystick when it is at its center position.
Claim 11
Dependent Claim
49 words
The device of claim 8, further comprising a 2N+1th position rached by moving said joystick to one side away from its center position and in said plane, and to a 2N+2th position reached by moving said joystick to another side away from its center position and in said plane.
