Interactive video display system
View Patent ↗An interactive video display system. A display screen is for displaying a visual image for presentation to a user. A camera is for detecting an object in an interactive area located in front of the display screen, the camera operable to capture three-dimensional information about the object. A computer system is for directing the display screen to change the visual image in response to the object.
1. An interactive video display system comprising:
means for displaying video data to a user;
means for providing three-dimensional information about the user;
means for processing the three-dimensional information;
means for determining a hand gesture of a hand of the user without the hand of the user contacting the means for displaying video data, wherein the hand gesture includes the hand of the user moving toward the video display and through a threshold separating an interactive zone from a touch zone; and
means for generating visual effects on the means for displaying video data, wherein the visual effects are based on the three-dimensional information and the hand gesture.
2. A method for receiving a user selection of an object displayed on an interactive video display, the method comprising:
displaying the object using the interactive video display, the interactive video display being visible to the user;
tracking positions of a hand of the user using a video camera, the video camera configured to provide three-dimensional information about the positions;
selecting the object based on a hand gesture of the hand of the user and without the hand of the user contacting the interactive video display, wherein the hand gesture includes the hand of the user moving toward the object and through a threshold, the threshold separating an interactive zone from a touch zone.
3. The method of claim 2 , wherein the interactive zone and the touch zone are volumetric regions at different distances from the interactive video display.
4. The method of claim 2 , wherein the hand gesture further includes a grabbing motion.
5. The method of claim 2 , further comprising releasing the selected object if the hand of the user is opened.
6. The method of claim 2 , further comprising releasing the selected object if the hand of the user is moved out of the touch zone.
7. The method of claim 2 , further comprising dragging the selected object in response to movement of the hand of the user.
8. The method of claim 2 , further comprising:
tracking the user using the video camera; and
generating visual effects using the interactive video display, the visual effects based on the tracking of the user.
9. The method of claim 8 , further comprising displaying a shape or outline of the user using the interactive video display.
10. The method of claim 2 , further comprising adjusting a volumetric region of the interactive zone when the field of view of the video camera includes a plurality of users.
11. The method of claim 2 , further comprising adjusting a volumetric region of the interactive zone to exclude one or more other users, wherein the one or more other users are beyond a closest user to interactive video display.
12. The method of claim 2 , wherein the object is a virtual button.
13. The method of claim 12 , wherein selecting the object based on the hand gesture includes the hand of the user moving over an image of the virtual button.
14. An interactive video display system comprising:
a video display;
a stereo camera configured to provide three-dimensional information about a user; and
a computer system coupled to the video display and the video camera, the computer system configured to:
execute instructions in memory to generate visual effects using the video display, the visual effects based on the three-dimensional information;
utilize a stereopsis algorithm to generate a depth map; and
determine different volumetric regions based on the depth map.
15. The interactive video display system of claim 14 , wherein the visual effects are responsive to a movement of the user.
16. The interactive video display system of claim 14 , wherein the different volumetric regions are further based on whether a field of view of the stereo camera includes a plurality of users.
17. The interactive video display system of claim 16 , wherein one of the different volumetric regions is adjusted to exclude one or more of the plurality of users when the one or more of the plurality of users is beyond a closest user to the video display.
18. The interactive video display of claim 14 , wherein the visual effects are further based on a hand gesture of the hand of the user and without the hand of the user contacting the video display, wherein the hand gesture includes the hand of the user moving toward the video display and through a threshold, the threshold separating an interactive zone from a touch zone.
19. The interactive video display system of claim 18 , wherein the computer system is further configured to select an object on the video display when the hand of the user moves toward the object.
20. The interactive video display of claim 18 , further comprising a virtual button displayed using the video display.
21. The interactive video display of claim 20 , wherein the computer system is further configured to select the virtual button when the hand of the user is in a touch zone and the hand of the user moves toward the virtual button.
