Abstract

An electronic wristwatch operable in two power modes. The wristwatch has an inertial sensor for detecting a gesture on a cover glass of the wristwatch. A touch panel is provided underneath the cover glass for detecting the gesture. Gesture detection by the inertial sensor is combined with gesture detection by the touch panel for triggering a switch from a first power mode to a second power mode.

Claims

1. A method for switching a wristwatch from a first power mode to a second power mode, comprising:

using an accelerometer for detecting a wristturn, and

switching said wristwatch from said first power mode to said second power mode when a wristturn has been detected,

wherein said step of detecting a wristturn comprises;

detecting that an orientation of the wristwatch is in a starting position, wherein said step of detecting that the orientation is in the starting position comprises detecting that the orientation of the wristwatch is held within a first range for a defined time;

detecting that an orientation of the wristwatch is then in a final position, wherein said step of detecting that the orientation is in the final position comprises detecting that the orientation is in a second range different from said first range,

in response to a detection that the orientation of the wristwatch is in the second range, detecting that the wristwatch remains substantially immobile during a predetermined duration and that a duration between the starting position and the final position is in a predefined range.

2. The method of claim 1, wherein

said first range is an angle range from 25°

to 155°

relatively to the horizontal.

3. The method of claim 1, wherein

said second range is an angle range from −

25°

to −

75°

relatively to the horizontal.

4. The method of claim 1, wherein said step of detecting that the wristwatch remains substantially immobile during a predetermined duration comprises:

detecting that an orientation of the wristwatch is held in a range from −

25°

to −

60°

relatively to the horizontal during said predetermined duration.

5. The method of claim 1, wherein said defined time is 50 ms.

6. The method of claim 1, wherein comprising a step of

in response to a detection that the orientation of the wristwatch is held within this second range for a defined time, registering that an orientation of the wristwatch is in the final position;

wherein

said duration between the starting position and the final position is provided by measuring a duration between the starting position and the registering of the final position.

7. The method of claim 6, wherein said defined time is 50 ms.

8. The method of claim 1, wherein said step of detecting that the orientation of the wristwatch is in a second range comprises:

detecting that a duration between the wristwatch being held in the first range and the wristwatch being held in the second range is in a predefined third range.

9. The method of claim 1, wherein

said step of detecting that the orientation of the wristwatch is then in a second range comprises detecting that a display of the wristwatch is oriented towards a face of the user.

10. The method of claim 1, wherein said steps of detecting that the orientation of the wristwatch is in a first range and then in a second range comprise:

in response of a detection of the orientation of the wristwatch is in the second range, checking if the orientation of the wristwatch was in the first range during a previous step.
