Abstract

A display system (100) comprises: a display device (102) being arranged to generate a first view (112) in a first direction relative to the display device (102) and to generate a second view (114) in a second direction relative to the display device (102), the second direction being different from the first direction; user-input means (104) for accepting user-input by means of detecting a position of a hand (110, 111) of an user (116) or of a pointing device held by the hand, the position relative to the display device (102), the userinput means (104) being arranged to control the first view (112) and the second view (114) on basis of the detection; and observation means (106) for observation of the user (116) and arranged to detect whether the user-input is provided to control the first view (112) or the second view (114), on basis of the observation.

Claims

1. A display-system (100,400,700), comprising:

a display device (102) being arranged to generate a first view (112) in a first direction relative to the display device (102) and to generate a second view (114) in a second direction relative to the display device (102), the second direction being different from the first direction; and

user-input means (104) for accepting user-input by means of detecting a position of a hand (110, 111) of an user (116) or of a pointing device held by the hand, the position relative to the display device (102), the user-input means (104) being arranged to control the first view (112) and the second view (114) on basis of the detection, characterized in further comprising observation means (106) for observation of the user (116) and for detecting whether the user-input is provided to control the first view (112) or the second view (114), on basis of the observation and the first direction.

2. A display system (100,400,700) as claimed in claim 1, characterized in that the observation means (106) are arranged to determine an orientation (123, 124) of the hand (110, 111) of the user (116) relative to the display device (102) and to determine whether a first angle between the orientation (123, 124) of the hand (110, 111) and the first direction is less than a first predetermined threshold.

3. A display system (100,400,700) as claimed in claim 1, characterized in that the observation means (106) are arranged to determine an orientation (414, 418) of the wrist and/or lower arm of the user (116) relative to the display device (102) and to determine whether a second angle between the orientation (414, 418) of the wrist and/or lower arm and the first direction is less than a second predetermined threshold.

4. A display system (100,400,700) as claimed in claim 1, characterized in that the observation means (106) comprise computing means to compute a trajectory (600) of the hand (110a-110c) on basis of a number of detected positions of the hand (110a-110c) and to determine whether a third angle between a vector which represents the trajectory (600) of the hand (110a-110c), and the first direction is less than a third predetermined threshold.

5. A display system (100,400,700) as claimed in claim 1, characterized in that the observation means (106) are arranged to determine the position of the eyes of the user (116) relative to the display device (102) and to determine whether a fourth angle between a direction of a vector from the display device (102) to a first one of the eyes and the first direction is less than a fourth predetermined threshold.

6. A display system (100, 700) as claimed in claim 1, characterized in that the observation means (106) comprise optical means for imaging the user (116).

7. A display system (400,700) as claimed in claim 1, characterized in that the observation means (106) are arranged to observe the user (116) on basis of acoustic, ultraviolet or radio frequency waves.

8. A display system (400,700) as claimed in claim 1, characterized in that the observation means (106) are arranged to observe the user (116) on basis of measuring temperature differences.

9. A display system (400,700) as claimed in claim 7, characterized in that the observation means (106) are located adjacent to the display device (102).

10. A display system (100,400,700) as claimed in claim 1, characterized in that the user-input means (104) comprise the observation means (106).

11. An apparatus (320, 420) comprising the display system (100,400,700) as claimed in claim 1.

12. An apparatus (420) as claimed in claim 11, characterized in that it is a personal digital assistant.

13. An apparatus (320) as claimed in claim 11, characterized in that it is a mobile phone.

14. A vehicle (440) comprising the display system (100,400,700) as claimed in claim 1.

15. A vehicle (440) as claimed in claim 14, characterized in that it is a car.
