1. A computer input apparatus, comprising:
- a base provided with a socket;
a ball segment located in the socket and rotatable in the socket, the ball segment being shaped to support a wrist of a user;
a handle attached to and extending away from the ball segment and configured such that when the user'"'"'s wrist is supported by the ball segment, the handle is adjacent to the user'"'"'s hand and maybe held by the user.

2. A computer input apparatus, comprising:
-
a base, the base being provided with a socket; a ball segment located in the socket and rotatable in the socket, the ball segment being pivotable about a first axis, bankable about a second axis orthogonal to the first axis, and twistable about a third axis orthogonal to the first and second axis; and a twist detection mechanism for measuring twist of the ball about the third axis, the twist detection mechanism comprising a detector and a detectable element moveable relative to each another, one of the detector and the detectable element being slideably and rotatably connected to the ball segment, such that pivoting of the ball segment about the first axis or banking of the ball segment about the second axis does not affect the position of the detector or the detectable element, and such that twisting of the ball about the third axis does affect the position of one of the detector and the detectable element. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

26. A computer input apparatus comprising:
-
a casing, the casing being connected to, and moveable relative to a base; a post, attached to the casing, which extends towards the base; and a return to zero mechanism for returning the position of the post and the casing to an equilibrium position when no pressure is applied to the casing, wherein the return to zero mechanism comprises; a support structure defining an aperture through which the post extends; and a plurality of arms pivotably attached to the support structure, the plurality of arms extending into the aperture and being biased toward the centre of the aperture, the plurality of arms being arranged to return the position of the post, and casing to which it is attached, to a zero position. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)

35. A computer input apparatus comprising:
-
a casing, the casing being connected to, and moveable relative to a base; and an anti-twist device for preventing twist of the casing relative to the base;
wherein the apparatus further comprises a clutch mechanism, comprising;a first surface; a second surface; and a biasing member arranged to bias the first surface away from contact with the second surface when no pressure is applied to the first surface; wherein the clutch mechanism is arranged such that, when sufficient pressure is applied to the first surface to overcome the biasing member, the first surface contacts the second surface and disengages the anti-twist device, thereby allowing twist of the casing relative to the base. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
