Abstract
Abstract A device particularly for use with a computer comprises a housing for location at least partly between two fingers of a user's hand and an electronic circuit mounted on a board within the housing. The circuit includes a switch responsive to pressure selectively to open and close an electronic circuit, and conductive elements arranged on the board mounting the electronic circuit. A first control element is mounted with the housing and responsive to finger pressure such that pressure applied to the first control element causes the element to operate the switch. The first control element is movable with respect to a hinge such that finger action acts to cause the control element to swivel as a trigger about the hinge and thereby interact with the switch. The second control element includes a flexible material mounted such that pressure applied to the flexible material in different directions and positions acts to change the electrical relationship between the conductive elements on the board and thereby vary an output signal from the electronic circuit. The rear portion of the housing includes a receptacle for receiving removable battery power supply for powering the electronic circuit. There is an infra-red output signal transmitted to a receiver for operating the computer. The first control element is located substantially below the second control element, and the first control element being in a bottom face of the housing.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
274 words
A portable, trigger operated pointing device for use with an electronically responsive system, comprising: a housing for location at least partly between first and second fingers of a user's hand, the housing having an elongate profile defining a longitudinal axis and having a forward end, a rear end, opposed sides, a top face, and a bottom face, the bottom face including a contoured step positioned medially of the forward and rear ends and transversely of the opposed sides, the contoured step having a first face for generally providing a rest location for the first finger of the user's hand; an electronic circuit mounted on a board contained within the housing, the circuit including on opposite sides of the board a switch responsive to pressure selectively to open and close an electronic circuit and a transducer responsive element; a first control element mounted with the housing at the first face of the contoured step and operatively connected to the switch to respond to pressure applied by the first finger of the user's hand to operate the switch; a second control element mounted with the housing at the top face and responsive to force applied by the second finger of the user's hand such that force applied to the second element in a selected direction acts to cause a change in a condition of the transducer responsive element and thereby cause the electronic circuit to provide a corresponding output signal; and an output signal emitter responsive to the output signal provided by the electronic circuit and positioned to transmit from the forward end a transmitted output signal propagating in a direction generally along the longitudinal axis.
Claim 2
Dependent Claim
274 words
A portable, trigger operated pointing device for use with an electronically responsive system, comprising: a housing for location at least partly between first and second fingers of a user's hand, the housing having an elongate profile defining a longitudinal axis and having a forward end, a rear end, opposed sides, a top face, and a bottom face, the bottom face including a contoured step positioned medially of the forward and rear ends and transversely of the opposed sides, the contoured step having a first face for generally providing a rest location for the first finger of the user's hand; an electronic circuit mounted on a board contained within the housing, the circuit including on opposite sides of the board a switch responsive to pressure selectively to open and close an electronic circuit and a transducer responsive element; a first control element mounted with the housing at the first face of the contoured step and operatively connected to the switch to respond to pressure applied by the first finger of the user's hand to operate the switch; a second control element mounted with the housing at the top face and responsive to force applied by the second finger of the user's hand such that force applied to the second element in a selected direction acts to cause a change in a condition of the transducer responsive element and thereby cause the electronic circuit to provide a corresponding output signal; and an output signal emitter responsive to the output signal provided by the electronic circuit and positioned to transmit from the forward end a transmitted output signal propagating in a direction generally along the longitudinal axis.
Claim 3
Dependent Claim
53 words
A device as claimed in claim 1, wherein the first control element is located in a position to act as a trigger movable under pressure at least partly towards the rear end, such movement acting to operate the switch for the electronic circuit, and the switch being a mechanical element for the circuit.
