Abstract
Abstract An orientation-operated cursor control device having a housing which is hand-holdable by a user. The housing rotatably carries a orientation maintaining member having a center of rotation which is offset from a center of gravity. An encoder generates input information for the computer in response to relative rotation of the housing and orientation maintaining member.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
121 words
A gravity operated device for delivering input information to a remote computer, comprising: a hand-held housing; an gravity operated member rotatably carried by said housing, said gravity operated member having a spherical external surface and a depending counterweight whereby the center of rotation of the member is offset from its center of gravity; a ball having a spherical surface portion engageable with the spherical external surface of the member; encoder means operatively engaged with the ball for generating said input information responsive to relative rotation of said housing and said gravity operated member produced by an absolute rotation of said housing in space; and means for coupling the encoder means to the computer to deliver said input information to the computer.
Claim 2
Dependent Claim
121 words
A gravity operated device for delivering input information to a remote computer, comprising: a hand-held housing; an gravity operated member rotatably carried by said housing, said gravity operated member having a spherical external surface and a depending counterweight whereby the center of rotation of the member is offset from its center of gravity; a ball having a spherical surface portion engageable with the spherical external surface of the member; encoder means operatively engaged with the ball for generating said input information responsive to relative rotation of said housing and said gravity operated member produced by an absolute rotation of said housing in space; and means for coupling the encoder means to the computer to deliver said input information to the computer.
Claim 3
Dependent Claim
20 words
The device of claim 1 wherein said gravity operated member has a spherical external surface and a nonuniform internal construction.
Claim 4
Dependent Claim
19 words
The device of claim 1 wherein said gravity operated member is carried by a gimbal mechanism of said housing.
Claim 5
Dependent Claim
27 words
The device of claim 1 wherein said gravity operated member is supported by an interaction of its spherical surface portion with a mating portion of said housing.
Claim 6
Dependent Claim
19 words
The device of claim 1 wherein said gravity operated member includes a counterweight connected to said spherical surface portion.
Claim 7
Dependent Claim
20 words
The device of claim 1 wherein the input information provides control for a pointer on a display of said computer.
Claim 8
Dependent Claim
21 words
The device of claim 1 wherein the means for coupling comprises a wired link between the device and the remote computer.
Claim 9
Dependent Claim
16 words
The device of claim 1 wherein said gravity operated member is located entirely within said housing.
Claim 10
Dependent Claim
32 words
The device of claim 8 wherein said gravity operated member is carried within a fixture portion of said housing, said fixture portion is removeably securable to a base portion of said housing.
Claim 11
Dependent Claim
26 words
The device of claim 9 wherein said fixture portion forms a handle, which handle further has a trigger which may be depressed to activate a switch.
Claim 12
Dependent Claim
21 words
The device of claim 9 further comprising a handle having a grip portion depending from a rear end of the device.
Claim 13
Dependent Claim
54 words
The device of claim 11 wherein said means for coupling the encoder means to the computer comprises wiring passing through the grip portion and wherein the handle has a base portion extending forward from a bottom of the grip portion and a front portion extending upwardly from the base portion to join the fixture.
Claim 14
Dependent Claim
117 words
A fixture for enhancing the operation of a conventional computer mouse having a rotatable member for producing cursor control information to be transmitted to a computer comprising: a housing adopted to be attached to the computer mouse; a gravity operated member rotatably mounted in said housing, said gravity operated member having a center of gravity offset from its center of rotation, the housing being attached to the mouse such that the rotatable member is in surface contact with the gravity operated member whereby side to side rolling movements and pitch and yaw movements of the computer mouse in space produce relative rotation of the gravity operated member and the rotatable member to generate the cursor control information.
Claim 15
Dependent Claim
117 words
A fixture for enhancing the operation of a conventional computer mouse having a rotatable member for producing cursor control information to be transmitted to a computer comprising: a housing adopted to be attached to the computer mouse; a gravity operated member rotatably mounted in said housing, said gravity operated member having a center of gravity offset from its center of rotation, the housing being attached to the mouse such that the rotatable member is in surface contact with the gravity operated member whereby side to side rolling movements and pitch and yaw movements of the computer mouse in space produce relative rotation of the gravity operated member and the rotatable member to generate the cursor control information.
Claim 16
Independent Claim
95 words
A device for modifying a ball-type computer mouse for producing computer input information responsive to pitch and roll orientations of the mouse, comprising: a fixture securable to the mouse; and a gravity operated member rotatably carried by the fixture and having a center of rotation offset from the center of gravity of the member and having a surface portion engageable with the ball of said mouse for producing a rotation of said ball responsive to rotation of the mouse when said device and mouse is held in space and subjected to pitch and roll movement.
Claim 17
Independent Claim
95 words
A device for modifying a ball-type computer mouse for producing computer input information responsive to pitch and roll orientations of the mouse, comprising: a fixture securable to the mouse; and a gravity operated member rotatably carried by the fixture and having a center of rotation offset from the center of gravity of the member and having a surface portion engageable with the ball of said mouse for producing a rotation of said ball responsive to rotation of the mouse when said device and mouse is held in space and subjected to pitch and roll movement.
Claim 18
Dependent Claim
23 words
The device of claim 14 wherein said surface portion is a spherical surface portion engageable with a spherical external surface of the ball.
Claim 19
Dependent Claim
19 words

Claim 20
Dependent Claim
27 words
The device of claim 15 wherein said gravity operated member is supported by an interaction of its spherical surface portion with a mating portion of said fixture.
Claim 21
Dependent Claim
19 words
The device of claim 15 wherein said gravity operated member bears a counterweight external to said spherical surface portion.
