Abstract

Methods, apparatus, and computer programs for controlling a view of a virtual scene with a handheld device are presented. In one method, images of a real world scene are captured using a device. The method further includes operations for creating an augmented view for presentation on a display of the device by augmenting the images with virtual reality objects, and for detecting a hand in the images as extending into the real world scene. In addition, the method includes operations for showing the hand in the screen as detected in the images, and for generating interaction data, based on an interaction of the hand with a virtual reality object, when the hand makes virtual contact in the augmented view with the virtual reality object. The augmented view is updated based on the interaction data, which simulates on the screen that the hand is interacting with the virtual reality object.

Claims

1. A method comprising:

capturing images of a real world scene using a handheld device;

creating an augmented view for presentation on a display screen of the handheld device by augmenting the captured images with one or more virtual reality objects;

detecting a user hand in the captured images as extending into the real world scene;

showing the user hand in the display screen as detected in the captured images;

generating interaction data based on an interaction of the user hand with a first virtual reality object from the one or more virtual reality objects when the user hand makes virtual contact in the augmented view with the first virtual reality object; and

updating the augmented view based on the interaction data, wherein the interaction data simulates on the display screen that the user hand is interacting with the first virtual reality object.

2. The method as recited in claim 1, wherein the interaction of the user hand is an action on the first virtual reality object selected from a group consisting of holding, pushing, pulling, moving, hitting, throwing, opening, closing, turning on or off, pushing a button, firing a weapon, or eating the first virtual reality object.

3. The method as recited in claim 1, wherein creating the augmented view further includes:

determining a location of the handheld device utilizing one or more of image analysis of the captured, or data obtained from inertial systems within the handheld device, or GPS, or ultrasonic triangulation, or WiFi communications, or dead reckoning.

4. The method as recited in claim 1, wherein in the augmented view the one or more virtual reality objects change with a geometrical perspective as if the one or more virtual reality objects were in the real world scene.

5. The method as recited in claim 1, wherein creating the augmented view further includes:

detecting a table in the real world scene; and

placing a second virtual reality object on top of the table as if the second virtual reality object was resting on the table.

6. The method as recited in claim 1, wherein the interaction data is associated with the user hand grabbing the first virtual reality object.

7. The method as recited in claim 6, wherein the interaction includes moving the first virtual reality object after the user hand grabs the first virtual reality object.

8. The method as recited in claim 1, wherein the user hand is able to manipulate the first virtual reality object to change a position or a property of the first virtual reality object as if the first virtual reality object were a real object.

9. The method as recited in claim 1, wherein the augmented view simulates that a camera in a back of the handheld device moves within the real world scene.

10. The method as recited in claim 1, wherein the first virtual reality object is a chess piece, wherein the interaction of the user hand includes one or more of grabbing the chess piece, or moving the chess piece, or releasing the chess piece.

11. A method comprising:

capturing images of a real world scene using a plurality of handheld devices associated with a plurality of users;

creating augmented views for presentation on respective display screens of the handheld devices by augmenting the captured images with one or more virtual reality objects;

detecting a user hand in first captured images of a first handheld device, the user hand extending into the real world scene;

showing the user hand in a first display screen of the first handheld device as detected in the first captured images;

generating interaction data based on an interaction of the user hand with a first virtual reality object from the one or more virtual reality objects when the user hand makes virtual contact with the first virtual reality object in a first augmented view of the first handheld device; and

updating the first augmented view based on the interaction data, wherein the interaction data simulates on the first display screen that the user hand is interacting with the first virtual reality object.

12. The method as recited in claim 11, further including:

synchronizing the plurality of handheld devices to a reference point in the real world scene.

13. The method as recited in claim 11, wherein each handheld device is operable to detect a user hand of the respective user and generate interaction data based on the interaction of the respective user with any of the one or more virtual reality objects.

14. The method as recited in claim 11, wherein the interaction of the user hand is an action on the first virtual reality object selected from a group consisting of holding, or opening, or smashing.

15. The method as recited in claim 11, further including:

exchanging among the plurality of handheld devices image information, relative motion, and ping data.

16. The method as recited in claim 11, exchanging among the plurality of handheld devices image information, relative motion, and positional information to synchronize calibrated positions for the plurality of handheld devices in the augmented views.

17. The method as recited in claim 11, wherein augmented views in respective displays from the plurality of handheld devices are independent from each other and the respective augmented views are based on a position of the respective handheld device.

18. The method as recited in claim 11, wherein the augmented view includes a virtual board game, wherein players holding respective handheld devices play a virtual board game.

19. A non-transitory computer-readable storage medium storing a computer program, the computer-readable storage medium comprising:

program instructions for capturing images of a real world scene using a handheld device;

program instructions for creating an augmented view for presentation on a display screen of the handheld device by augmenting the captured images with one or more virtual reality objects;

program instructions for detecting a user hand in the captured images as extending into the real world scene;

program instructions for showing the user hand in the display screen as detected in the captured images;

program instructions for generating interaction data based on an interaction of the user hand with a first virtual reality object from the one or more virtual reality objects when the user hand makes virtual contact in the augmented view with the first virtual reality object; and

program instructions for updating the augmented view based on the interaction data, wherein the interaction data simulates on the display screen that the user hand is interacting with the first virtual reality object.

20. The storage medium as recited in claim 19, wherein creating augmented views further includes:

adding a shadow of the user hand over the one or more virtual reality objects according to lighting conditions in the real world scene.
