Abstract

A user input device is described. In an embodiment the user input device is hand held and comprises a sensing strip to detect one-dimensional motion of a user'"'"'s finger or thumb along the sensing strip and to detect position of a user'"'"'s finger or thumb on the sensing strip. In an embodiment the sensed data is used for cursor movement and/or text input at a master device. In an example the user input device has an orientation sensor and orientation of the device influences orientation of a cursor. For example, a user may move the cursor in a straight line in the pointing direction of the cursor by sliding a finger or thumb along the sensing strip. In an example, an alphabetical scale is displayed and a user is able to zoom into the scale and select letters for text input using the sensing strip.

Claims

1. A hand-held user input device comprising:

a sensing strip arranged to detect one-dimensional motion of a user'"'"'s thumb or finger relative to the strip and to detect position of a user'"'"'s thumb or finger on the strip in use;

the sensing strip being sized and shaped such that a user'"'"'s thumb or finger may slide along the strip in use;

a housing supporting the sensing strip and sized and shaped to be held in a user'"'"'s hand in use;

a processor supported in the housing and arranged to receive sensed data from the sensing strip and to control a communication unit supported in the housing;

the communication unit being connected to the processor and arranged to send the sensed data to a master device in order to control movement and position of a cursor at a user interface of the master device in use, the user interface displaying the cursor and a direction beam extending at least forward from the cursor in a direction associated with the orientation of the input device, forward being the direction toward which the cursor is pointed.

2. A device as claimed in claim 1 wherein the sensing strip is a capacitive strip over which an electrical potential difference is applied and wherein changes in the electrical potential difference are monitored according to position and movement of a user'"'"'s thumb or finger along the sensing strip in use.

3. A device as claimed in claim 1 wherein the sensing strip is a potentiometer strip.

4. A user input device as claimed in claim 1 comprising at least one orientation sensor supported in the housing and wherein the communication unit is arranged to send output from the orientation sensor to the master device in order to control orientation of a cursor at a user interface of the master device in use.

5. A user input device as claimed in claim 1 comprising a switch supported by the housing and arranged to be pressed by the user and wherein the communication unit is arranged to send output from the switch to the master device in order to indicate a user selection at a user interface of the master device in use.

6. A user input device as claimed in claim 5 wherein the switch is supported by the housing by any of:

being incorporated in a handle of the device, being under the sensing strip, being between the sensing strip and a handle of the device such that relative movement between the sensing strip and handle activates the switch.

7. A user input device as claimed in claim 1 wherein the sensing strip is approximately the same width as a human thumb.

8. A user input device as claimed in claim 1 wherein the sensing strip is circular or semi-circular.

9. A user input device as claimed in claim 1 comprising a haptic feedback mechanism arranged to provide haptic feedback to a user when a user slides a finger or thumb along the sensing strip in use.

10. A user input device as claimed in claim 1 comprising a video camera and a microphone and wherein the communication unit is arranged to transfer data from the video camera and the microphone to the master device such that the device may be used for video conferencing in conjunction with the master device.

11. A user input device as claimed in claim 1 arranged to enable a user to input text to the master device.

12. A method at a master device having a graphical user interface comprising:

receiving data from a user input device, the data indicating one-dimensional motion of a user'"'"'s thumb or finger relative to a sensing strip and the detected position of a user'"'"'s thumb or finger on the sensing strip;

receiving orientation data from the user input device indicating an orientation of the device;

displaying a cursor at the graphical user interface such that it points in a direction related to the orientation data;

displaying a direction beam extending at least forward from the cursor in the direction associated with the orientation of the input device, forward being the direction toward which the cursor is pointed;

displaying the cursor at the graphical user interface such that the one-dimensional motion of the user'"'"'s thumb or finger maps to motion of the cursor in a straight line extending from the cursor in its pointing direction and such that the detected position of the user'"'"'s thumb or finger on the sensing strip maps to a position of the cursor which is on the straight line;

receiving an instruction to display an alphabetical scale and, responsive to the instruction, displaying the alphabetical scale at an orientation associated with the orientation of the input device; and

receiving motion data from the user input device, the motion data comprising at least one pre-defined gesture, and inserting at least one special character at the cursor location in response to receiving the motion data, the at least one special character being associated with the at least one pre-defined gesture.

13. A method as claimed in claim 12 which comprises displaying an alphabetical scale at the graphical user interface and displaying an indicator at a location on the scale selected according to the detected position of the user'"'"'s thumb or finger on the sensing strip.

14. A method as claimed in claim 13 which comprises receiving user input selection data from the user input device and displaying a zoomed in alphabetical scale according to the user input selection.

15. A method as claimed in claim 14 comprising selecting the letter adjacent the indicator as input to a text box displayed at the graphical user interface.

16. A method at a master device having a graphical user interface comprising:

receiving data from a user input device, the data indicating one-dimensional motion of a user'"'"'s thumb or finger relative to a sensing strip and the detected position of a user'"'"'s thumb or finger on the sensing strip;

receiving orientation data from the user input device indicating an orientation of the user input device;

receiving movement data from the user input device indicating movement of the user input device;

displaying a cursor at the graphical user interface such that it points in a direction related to the orientation data;

displaying a direction beam extending at least forward from the cursor in the direction associated with the orientation of the input device, forward being the direction toward which the cursor is pointed;

displaying the cursor at the graphical user interface such that the one-dimensional motion of the user'"'"'s thumb or finger maps to motion of the cursor in a straight line extending from the cursor in its pointing direction and such that the detected position of the user'"'"'s thumb or finger on the sensing strip maps to a position of the cursor which is on the straight line; and

in response to receiving movement data from the user input device, the movement data being associated with a user shaking the user input device, displaying an alphabetical scale at the graphical user interface, the orientation of the alphabetical scale being related to the orientation data, and displaying an indicator at a location on the scale selected according to the detected position of the user'"'"'s thumb or finger on the sensing strip.

17. A method as claimed in claim 16 which comprises receiving user input selection data from the user input device and displaying a zoomed in alphabetical scale according to the user input selection.

18. A method as claimed in claim 16 comprising selecting the letter adjacent the indicator as input to a text box displayed at the graphical user interface.
