Abstract
Abstract A mouse or trackball comprising a rotationally-symmetrical member (sphere or cylinder). The sphere or cylinder can be braked by means of baking means which receive an appropriate control signal from a data processing apparatus such as a computer. Mechanical feedback to the operator is thus realised. In accordance with the invention, the mouse or trackball also comprises acceleration means which are capable of positively accelerating the sphere or cylinder in a desired direction. The mechanical feedback is thus substantially improved.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
131 words
A data input device for use with a data processing apparatus, said device comprising a housing that contains a physical member having at least one axis of rotational symmetry and allowing rotational manipulation around any said axis with respect to said housing, said device having sensing means for upon said manipulation feeding a sensing signal to said data processing apparatus for thereupon moving a display indicium according to an aggregation of said manipulation on a display means, said device having control means for in response to said sensing signal braking said rotational manipulation, characterized in that said control means control both positive and negative accelerations with respect to said rotational manipulation as governed by said data processing apparatus according to a position signal of said display indicium on said display means.
Claim 2
Dependent Claim
23 words
A device as claimed in Claim 1, wherein said positive and negative accelerations derive from a potential field mapped on said display means.
Claim 3
Dependent Claim
27 words
A device as claimed in Claim 1 or 2, wherein said positive and negative accelerations are at least codetermined by an actual velocity of said rotational manipulation.
Claim 4
Dependent Claim
16 words
A device as claimed in Claim 1, 2 or 3, wherein said physical member is spherical.
Claim 5
Independent Claim
31 words
A device as claimed in any of Claims 1 to 4, wherein said sensing means alow for detecting an actual total force on said member in at least one coordinate direction.
Claim 6
Independent Claim
29 words
A device as claimed in any of Claims 1 to 5, wherein said sensing means allow for detecting an instantaneous velocity of said member with respect to the housing.
Claim 7
Independent Claim
16 words
A device as claimed in any of Claims 1 to 6, wherein said accelerations are multivalued.
Claim 8
Independent Claim
25 words
A device as claimed in any of Claims 1 to 7, provided with assigning means for assigning to the member a predetermined virtual rotational inertia.
Claim 9
Independent Claim
16 words
