Abstract

An apparatus that includes a touch panel configured to receive user input, a display configured to show content, a motion quality improvement functionality for the display, at least one sensor configured to detect a pointing device approaching the apparatus, and a control unit configured to selectively activate the motion quality improvement functionality for the display in response to the detection of an approaching pointing device by the sensor.

Claims

1. An apparatus comprising

a touch panel configured to receive user input,

a display configured to show content,

a motion quality improvement functionality for the display,

at least one sensor configured to detect a pointing device approaching the apparatus, and

a control unit configured to selectively activate the motion quality improvement functionality for the display in response to the detection of an approaching pointing device by the at least one sensor.

2. An apparatus of claim 1, wherein the at least one sensor employs proximity sensing technology.

3. An apparatus of claim 1, wherein the pointing device is one of a finger of a user of the apparatus and a stylus.

4. An apparatus of claim 1, wherein the touch panel and the display are part of an integrated touch display.

5. An apparatus of claim 1, wherein the at least one sensor is part of the touch panel.

6. An apparatus of claim 1, wherein the at least one sensor and the touch panel are separate components.

7. An apparatus of claim 1, wherein the at least one sensor is configured to detect a movement vector with which the pointing device is approaching the apparatus, and the control unit is configured to decide whether to activate the motion quality improvement functionality at least on the basis of the movement vector.

8. An apparatus of claim 1, wherein the at least one sensor is configured to detect an arrival angle with which the pointing device is approaching the apparatus, and the control unit is configured to decide whether to activate the motion quality improvement functionality at least on the basis of the arrival angle.

9. An apparatus of claim 1, wherein the control unit is configured to determine the gesture the pointing device is likely to make and to decide whether to activate the motion quality improvement functionality at least on the basis of the determined gesture.

10. An apparatus of claim 9, wherein the determined gesture is a tapping gesture and the control unit is configured to decide whether to activate the motion quality improvement functionality on the basis of a combination of the determined gesture and an application that the approaching pointing device is likely to select.

11. An apparatus of claim 9, wherein the determined gesture is sweeping or scrolling gesture and the control unit is configured to decide whether to activate the motion quality improvement functionality on the basis of a combination of the determined gesture and an application that is currently active in the apparatus.

12. An apparatus of claim 1, wherein the control unit is configured to decide whether to activate the motion quality improvement functionality at least on the basis of location of the approaching pointing device and the content shown on the display.

13. An apparatus of claim 1, wherein the control unit is configured to decide whether to activate the motion quality improvement functionality at least on the basis of an application that the approaching pointing device is likely to select.

14. An apparatus of claim 1, wherein the control unit is configured to decide whether to activate the motion quality improvement functionality at least on the basis of an application that is currently active in the apparatus.

15. An apparatus of claim 1, wherein the control unit is configured to control level of the motion quality improvement functionality in response to the detection of an approaching pointing device.

16. A method comprising

automatically detecting that a pointing device is approaching an apparatus that comprises a display, and

selectively performing automatic activation of a motion quality improvement functionality for the display in response to the detection of the approaching pointing device.

17. A method of claim 16, further comprising

determining a movement vector with which the pointing device is approaching the apparatus, and

deciding whether to activate the motion quality improvement functionality at least on the basis of the movement vector.

18. A method of claim 16, further comprising

deciding whether to activate the motion quality improvement functionality at least on the basis of an application that the approaching pointing device is likely to select.

19. A method of claim 16, further comprising

deciding whether to activate the motion quality improvement functionality at least on the basis of an application that is currently active in the apparatus.

20. A computer program embodied on a computer readable medium comprising computer executable program code which, when executed by at least one processor of an apparatus that comprises a display, causes the apparatus to:

detect that a pointing device is approaching the apparatus, and

selectively perform activation of a motion quality improvement functionality for the display in response to the detection of the approaching pointing device.
