Abstract

Technologies are generally described for pausing and resuming a gesture-based game. In some examples, a method performed under control of a gesture-based game system includes receiving a pause command that indicates pausing play of a gesture-based game and in response to the receipt of the pause command, capturing a first image of a player currently playing the gesture-based game, the first image being associated with a first posture of the player substantially at the time of the pause command and generating an outline of the player corresponding to the first image of the player.

Claims

1. A method performed under control of a processor for a gesture-based game system, comprising:

receiving, by the processor, a pause command to pause play of a gesture-based game;

capturing, by the processor, a first image of a player using a camera, the first image including the player in a first posture at a substantially same time as the receiving of the pause command;

generating, by the processor, an outline of the player corresponding to the first image of the player,

wherein the generating the outline of the player includes calculating, by the processor;

x-y coordinates of the outline of the player, and

positions of pixels included in the outline based, at least in part, on the calculated x-y coordinates of the outline of the player;

pausing, by the processor, the play of the gesture-based game;

capturing, by the processor, a second image of the player using the camera, the second image including the player in a second posture after the receiving of the pause command;

determining, by the processor, whether the second image of the player substantially matches the outline of the player corresponding to the first image,

wherein the determining includes;

comparing, by the processor, the second image of the player with the positions of pixels of the outline of the player, and

determining, by the processor, whether the second image of the player is entirely enclosed in the outline of the player based, at least in part, on the comparison of the second image of the player with the positions of pixels of the outline of the player; and

resuming, by the processor, the play of the gesture-based game upon determining that the second image substantially matches the outline of the player corresponding to the first image.

2. The method of claim 1, wherein, if the second image is entirely enclosed in the outline, the determining whether the second image of the player substantially matches the outline of the player corresponding to the first image further includes:

calculating, by the processor, a ratio of an area of the second image to an area of the outline; and

determining, by the processor, whether the ratio of the area of the second image to the area of the outline is greater than a predetermined ratio threshold.

3. The method of claim 1, wherein, if the second image is not entirely enclosed in the outline, the determining whether the second image of the player substantially matches the outline of the player corresponding to the first image further includes:

calculating, by the processor, an area of a part of the second image out of the outline, a ratio of an area of the second image enclosed in the outline to an area of the outline, and a ratio of the area of the part of the second image out of the outline to the area of the outline;

deducting, by the processor, the ratio of the area of the part of the second image out of the outline to the area of the outline from the ratio of the area of the second image enclosed in the outline to the area of the outline; and

determining, by the processor, whether a difference between the ratio of the area of part of the second image out of the outline to the area of outline and the ratio of the area of the second image enclosed in the outline to the area of the outline is greater than a predetermined ratio threshold.

4. The method of claim 1, further comprising:

displaying, by the processor, on a screen coupled to the gesture-based game system, the generated outline of the player.

5. The method of claim 1, further comprising:

identifying, by the processor, an avatar image associated with the first image of the player, and

wherein the generating the outline of the player is based, at least in part, on the avatar image.

6. The method of claim 1, wherein the generating the outline of the player further includes calculating, by the processor, a distance between the player and the gesture-based game system, and

wherein the determining further includes comparing, by the processor, the distance between the player and the gesture-based game system associated with the first image of the player and a distance between the player and the gesture-based game system associated with the second image of the player.

7. The method of claim 1, wherein the pause command includes a speech of the player.

8. The method of claim 1, wherein the pause command includes a gesture of the player.

9. A gesture-based game apparatus, comprising:

an input receiving unit configured to receive a pause command to pause play of a gesture-based game;

a camera configured to capture a first image of a player that includes the player in a first posture at a substantially same time as the receiving of the pause command;

an outline generating unit configured to generate an outline of the player corresponding to the first image of the player,

wherein the outline generating unit is configured to calculate x-y coordinates of the outline of the player and positions of pixels included in the outline based, at least in part, on the calculated x-y coordinates of the outline of the player;

a control unit configured to pause the play of the gesture-based game in response to the receipt of the pause command,

wherein the camera is further configured to capture a second image of the player that includes the player in a second posture after the receiving of the pause command,

a determination unit configured to determine whether the second image of the player substantially matches the outline of the player corresponding to the first image,

wherein the determination unit is configured to;

compare the second image of the player with the positions of pixels of the outline of the player, and

determine whether the second image of the player is entirely enclosed in the outline of the player based, at least in part, on the comparison of the second image of the player with the positions of the pixels of the outline of the player, and

wherein the control unit is further configured to resume the play of the gesture-based game upon determining that the second image substantially matches the outline of the player corresponding to the first image.

10. The apparatus of claim 9, if the second image is entirely enclosed in the outline, wherein the determination unit is further configured to:

calculate a ratio of an area of the second image to an area of the outline; and

determine whether the ratio of the area of the second image to the area of the outline is greater than a predetermined ratio threshold.
