Abstract

The present invention relates to a computer device comprising a detector for detecting a user's eye and a processor. The processor is configured to determine if the position of the user's eye is kept in a zone for a first time period, and if the position of the user's eye is kept in the zone for the first time period, suspend for a second time period detecting the user's eye and determining the position of the user's eye.

First claim

The invention claimed is:

1. A device for managing power consumption comprising:
a detector for detecting an eye in one of a plurality of view zones; and
a processor configured to:
determine if a position of the eye is kept in the one of the plurality of view zones for a first time period; and
if the position of the eye is kept in the one of the plurality of view zones for the first time period, reproduce a video content and suspend detecting the eye and determining the position of the eye for a second time period thereby reducing the power consumption of the device;
present for display a stereoscopic image including left and right views in the plurality of view zones, the plurality of view zones including alternately arranged first and second view zones in which the first view zone includes the left view to be presented to a left eye and the right view to be presented to a right eye and the second view zone includes the left view to be presented to the right eye and the right view to be presented to the left eye;
determine if the position of the eye moves from the first view zone into the second view zone; and
if it is determined that the position of the eye moves from the first view zone into the second view zone, switch the arrangement of left and right views in the second view zone to be displayed on the display so that the left view is presented to left eye and the right view is presented to right eye.

2. The device according to claim 1 , wherein the processor is further configured to:
after the second time period, repeat determining if the position of the eye is kept in the one of the plurality of view zones for the first time period and, if the position of the eye is kept in the one of the plurality of view zones for the first time period, suspend for the second time period detecting the eye and determining the position of the eye.

3. The device according to claim 2 , wherein the processor is further configured to:
reproduce a content even while the processor suspends detecting the eye and determining the position of the eye during the second time period.

4. The device according to claim 1 , wherein the processor is further configured to:
if the eye is not detected for a third time period, suspend detecting the eye and determining the position of the eye in the one of the plurality of view zones and pause reproducing of the video content.

5. A method of managing power consumption comprising:
detecting an eye in one of a plurality of view zones;
determining if a position of the eye is kept in the one of the plurality of view zones for a first time period;
if the position of the eye is kept in the one of the plurality of the view zones for the first time period, reproducing a video content and suspending detecting the eye and determining the position of the eye for a second time period thereby reducing the power consumption of the device
displaying on a display a stereoscopic image including left and right views in several view zones, the several view zones including alternately arranged first and second view zones in which the first view zone includes the left view to be presented to a left eye and the right view to be presented to a right eye and the second view zone includes the left view to be presented to the right eye and the right view to be presented to left eye;
determining if the position of the eye moves from the first view zone into the second view zone; and
if it is determined that the position of the eye moves from the first view zone into the second view zone, switching the arrangement of left and right views to be displayed on the display so that the left view is presented to the left eye and the right view is presented to the right eye.

6. The method according to claim 5 , further comprising repeating, after the second time period, determining if the position of the eye is kept in the one of the plurality of view zones for the first time period and, if the position of the eye is kept in the one of the plurality of view zones for the first time period, suspending for the second time period detecting the eye and determining the position of the eye.

7. The method according to claim 5 , further comprising reproducing a content even while suspending detecting the eye and determining the position of the eye during the second time period.

8. The method according to claim 5 , further comprising
if the eye is not detected in one of the plurality of the view zones for a third time period, suspending detecting the eye and determining the position of the eye, and pausing reproducing of the video content.

9. A non-transitory storage medium readable by a computer, the storage medium storing a program for a device comprising:
a detector for detecting an eye in one of a plurality of view zones; and
a processor,
the program causing the processor to:
determine if the position of the eye is kept in the one of the plurality of the view zones for a first time period; and
if the position of the eye is kept in the one of the plurality of the view zones for the first time period, reproduce a video content and suspend detecting the eye and determining the position of the eye for a second time period thereby reducing the power consumption of the device;
display on a display a stereoscopic image including left and right views in several view zones, the several view zones including alternately arranged first and second view zones in which the first view zone includes the left view to be presented to a left eye and the right view to be presented to a right eye and the second view zone includes the left view to be presented to the right eye and the right view to be presented to left eye,
determine if the position of the eye moves from the first view zone into the second view zone; and
if it is determined that the position of the eye moves from the first view zone into the second view zone, switch the arrangement of left and right views to be displayed on the display so that the left view is presented to the left eye and the right view is presented to the right eye.
