Abstract
Abstract An improved interface control advantageously may be operated by one hand. A thumbpiece is slidably disposed within a longitudinal arm member which moves in an arcuate path. Placing his or her thumb in the thumbpiece, a user controls the horizontal positioning of a cursor by moving the arm member along the arcuate path. Vertical positioning of the cursor is controlled by sliding the thumbpiece along the length of the arm member. Trigger functions are implemented by exerting a downward force on the thumbpiece. Since the downward force used to implement the trigger function is orthogonal to motions used to control positioning of the cursor irrespective of the particular positions of the arm member and thumbpiece, the disclosed interface control prevents a user from inadvertently altering the positioning of the cursor during implementation of the trigger function. The arm member and sliding thumbpiece emulate the natural pivoting and curling/extending motions of the thumb, thereby resulting in a precise, easy to use, and ergonomically superior interface control.

Claim 3
Dependent Claim
49 words
The apparatus of claim 1 further comprising: first guide means disposed along said arm member; and second guide means disposed on said contact member, said second guide means matingly coupled with said first guide means so as to facilitate the movement of said contact member along said arm member.
Claim 4
Dependent Claim
49 words
The apparatus of claim 2 wherein said first guide means comprise first and second grooves horizontally disposed in first and second side walls, respectively, of said arm member, said second guide means comprising first and second flanges disposed on first and second side walls of said contact member, respectively.
Claim 5
Dependent Claim
36 words
The apparatus of claim 1 wherein said arm member is pivotally coupled to said support at a pivot point, said arm member moving in said arcuate path as said arm member pivots about said pivot point.
Claim 6
Dependent Claim
61 words
The apparatus of claim 1 further comprising: a track means disposed within said support, said track means defining said arcuate path; and one or more guide elements disposed on an outer surface of said arm member, said one or more guide elements being matingly coupled to said track means for facilitating the movement of said arm member in said arcuate path.
Claim 7
Dependent Claim
34 words
The apparatus of claim 1 wherein said first sensor detects the magnitude and direction of arcuate movement of said arm member along said arcuate path and generates a first control signal in response thereto.
Claim 8
Dependent Claim
30 words
The apparatus of claim 1 wherein said second sensor detects the magnitude and direction of linear movement of said contact member and generates a second control signal in response thereto.
Claim 9
Dependent Claim
39 words
The apparatus of claim 1 further comprising a third sensor coupled to said arm member, said third sensor detecting a downward pressure on said contact member and in response thereto generating a signal for implementing a first predetermined function.
Claim 10
Independent Claim
93 words
An apparatus for generating at least two control signals, said apparatus comprising: a support; an arm member having a first end portion pivotally coupled to said housing at a point, said arm member being rotatable about said point; a contact member slidably mounted on said arm member, said contact member being slidable along said arm member; a first sensor coupled to said arm member for sensing arcuate movement of said arm member; and a second sensor coupled to said contact member for sensing linear movement of said contact member along said arm member.
Claim 11
Independent Claim
93 words
An apparatus for generating at least two control signals, said apparatus comprising: a support; an arm member having a first end portion pivotally coupled to said housing at a point, said arm member being rotatable about said point; a contact member slidably mounted on said arm member, said contact member being slidable along said arm member; a first sensor coupled to said arm member for sensing arcuate movement of said arm member; and a second sensor coupled to said contact member for sensing linear movement of said contact member along said arm member.
