Display orientation change for wireless devices
View Patent ↗A method for controlling an orientation of a display of a wireless device using a combination of accelerometer-determined orientation and camera-determined orientation, the camera being a frontal camera used to confirm or reverse the orientation found by the accelerometer.
1. A computer-implemented method for controlling an orientation of a display on a wireless device comprising:
using at least one acceleration measurement to determine a first orientation of the wireless device;
using at least one image to determine a second orientation of the wireless device;
detecting if there is a face in the at least one image and if no face is detected, selecting the first orientation as a display orientation;
if the face is detected and the first and second orientations do not match, selecting the second orientation as the display orientation;
if the face is detected and the first and second orientations match, selecting either one as the display orientation; and
providing the display as a whole on the wireless device in accordance with the display orientation.
2. The method of claim 1 , further comprising activating a frontal camera when the at least one acceleration measurement is received.
3. The method of claim 1 , wherein the using at least one image comprises using multiple images from an input video stream.
4. The method of claim 1 , wherein the display orientation is one of portrait and landscape.
5. The method of claim 1 , wherein the at least one acceleration measurement is an acceleration pattern.
6. The method of claim 1 , wherein the using at least one acceleration measurement from an accelerometer in the wireless device is performed during a predetermined period.
7. The method of claim 1 , further comprising receiving the at least one acceleration measurement from at least one accelerometer in the wireless device.
8. The method of claim 1 , further comprising acquiring the at least one image from a frontal camera of the wireless device.
9. The method of claim 1 , wherein a default orientation corresponds to a predetermined one of the first orientation and the second orientation, and the default orientation is used when the first orientation and the second orientation match.
10. A wireless device comprising:
a processor coupled to a memory, a display screen, at least one accelerometer, and a frontal camera and adapted for:
using at least one acceleration measurement to determine a first orientation of the wireless device;
using at least one image to determine a second orientation of the wireless device;
detecting if there is a face in the at least one image and if no face is detected, selecting the first orientation as a display orientation;
if the face is detected and the first and second orientations do not match, selecting the second orientation as the display orientation;
if the face is detected and the first and second orientations match, selecting either one as the display orientation; and
providing the display as a whole on the wireless device in accordance with the display orientation.
11. The wireless device of claim 10 , further comprising activating the frontal camera when the at least one acceleration measurement is received.
12. The wireless device of claim 10 , wherein the using at least one image comprises using multiple images from an input video stream.
13. The wireless device of claim 10 , wherein the display orientation is one of portrait and landscape.
14. The wireless device of claim 10 , wherein the at least one acceleration measurement is an acceleration pattern.
15. The wireless device of claim 10 , wherein the using at least one acceleration measurement from the accelerometer in the wireless device is performed during a predetermined period.
16. The wireless device of claim 10 , further comprising receiving the at least one acceleration measurement from at least one accelerometer in the wireless device.
17. The wireless device of claim 10 , further comprising acquiring the at least one image from the frontal camera of the wireless device.
18. The wireless device of claim 10 , wherein a default orientation corresponds to a predetermined one of the first orientation and the second orientation, and the default orientation is used when the first orientation and the second orientation match.
19. A non-transitory computer readable medium including program instructions recorded thereon for controlling an orientation of a display of a wireless device, the program instructions when executed configuring a processor of the wireless device for:
using at least one acceleration measurement to determine a first orientation of the wireless device;
using at least one image to determine a second orientation of the wireless device;
detecting if there is a face in the at least one image and if no face is detected, selecting the first orientation as a display orientation;
if the face is detected and the first and second orientations do not match, selecting the second orientation as the display orientation;
if the face is detected and the first and second orientations match, selecting either one as the display orientation; and
providing the display as a whole on the wireless device in accordance with the display orientation.
20. The non-transitory computer readable medium of claim 19 , further comprising receiving the least one acceleration measurement from at least one accelerometer in the wireless device.
21. The non-transitory computer readable medium of claim 19 , further comprising acquiring the at least one image from a frontal camera of the wireless device.
22. The non-transitory computer readable medium of claim 19 , wherein a default orientation corresponds to a predetermined one of the first orientation and the second orientation, and the default orientation is used when the first orientation and the second orientation match.
