Abstract

A data-input device comprises a designator able to point to a position on a screen of a computer system to which the device is intended to be connected and a body intended to be fixed to a workstation, the body comprising a support zone intended to support the hand of an operator as he manipulates the designator. The device further comprises a knob arranged in such a way that it can be manipulated by the fingers of the operator, his hand remaining supported on the support zone. The knob is configured to allow at least two distinct data selections of which one is a choice of values in a series and one is a binary acquisition in relation to the chosen value.

First claim

The invention claimed is:

1. A data-input device comprising a designator able to point to a position on a screen of a computer system to which the device is intended to be connected and a body intended to be fixed to a workstation, the body comprising a base defining a base plane and a support zone intended to support the hand of an operator as he manipulates the designator, the device further comprising two knobs, each of the knobs being configured to rotate about a respective axis of knob rotation, the designator being disposed at the base plane and between the two knobs, the two knobs being disposed on the body and above the designator, wherein the two axes of knob rotation are disposed at an angle relatively closer to parallel to the base plane than perpendicular to the base pane and the two axes of knob rotation are disposed at an angle relatively closer to parallel to each other, the two knobs being arranged in such a way that each knob can be manipulated by the fingers of the operator, his hand remaining supported on the support zone, each knob being configured to allow at least two distinct data selections of which one is a choice of values in a series and one is a binary acquisition in relation to the chosen value, each knob comprising a rotary ring rotating about an axis and allowing the choice of values in a series, the ring having a first zone and a second zone which are joined together and both having a substantially frustoconical shape extending around the axis and on which zones the operator can place his fingers, a smaller diameter (d) of the first zone about the axis being greater than or equal to a larger diameter (d) of the second zone about the axis, in which a vertex angle α2 of the first zone and a vertex angle α1 of the second zone are defined and in which the vertex angles satisfy the relationship:
0°≤α 1 <α 2 ≤90°.

2. The device according to claim 1 , in which the knob comprises a push-button switch configured for the binary acquisition.

3. The device according to claim 2 , in which the switch is arranged at the center of the ring and the switch is configured to be manipulated in a translational movement along the axis of the ring.

4. The device according to claim 1 , in which the knob is configured to allow an additional first data input by means of a rotation of the knob about a first axis perpendicular to the axis of rotation of the ring.

5. The device according to claim 4 , in which the knob is configured to allow a second additional data input by means of a rotation of the knob about a second axis perpendicular to the axis of rotation of the ring and perpendicular to first axis.

6. The device according to claim 4 , in which the additional data input or inputs allow acquisition of a choice of value in a given series.

7. The device according to claim 4 , in which the additional data input or inputs allow access to binary data.

8. The device according to claim 1 further comprising a palm rest on which the support zone is provided, in which device the palm rest extends mainly in an arc closing up toward a zone intended to accept the fingers of that hand of the operator that is manipulating the designator.

9. The device according to claim 8 , in which the arc has two ends and the knob is arranged at one of the ends of the arc.

10. The device according to claim 9 further comprising two knobs, each one arranged at one of the ends of the arc and the two knobs are intended to be manipulated either by one and the same operator or by two operators positioned differently in relation to the designator.
