Abstract

Techniques for providing a common input for multiple users are disclosed. Two separate input detection systems can be provided. One input detection system detects the identity of user while the other detects the location of input for processing. The information provided by the two detection systems is effectively reconciled to determine whether a particular user identified by the first system has provided input in a particular location indicated by the second system. Information can be reconciled, for example, at least partially based on the timing information provided by the two systems (e.g., whether the times indicated by the two systems are within an acceptable range). It will also be appreciated that both input system can be integrated into a single device which can be presented, for example, as multi-user touchscreen. The multi-user touch screen can provide a common input surface to serve numerous applications.

an input portion capable of being touched by said plurality of users;

a user-identifier component configured to;

detect that a particular one of the plurality of users has touched the input portion of the multi-user input device, and

provide a first indication indicating that a touch by the particular user has been detected at a first time by the user-identifier component;

a touch-locator component configured to;

detect a touch at a particular location of the input portion of the multi-user input device, and

provide a second indication indicating that a touch at the particular location has been detected at a second time by said touch-locator component; and

a controller configured to;

determine, based on the first indication and the second indication, whether the particular user has touched the input portion at the particular location of the input portion of the multi-user multi-touch input system, and

generate an output indicating that the particular user identified by the user-identifier component has touched the input portion of the multi-user multi-touch system at the particular location identified by the touch-locator component when the determining determines that the particular user has touched the input portion at the particular location of the input portion of the multi-user multi-touch input system.

2. The multi-user multi-touch input system of claim 1, wherein said user-identifier component is further configured to:

detect a change in Radio Frequency (RF) energy received by a RF receiver associated with the particular user when the particular user touches said input portion of said multi-user multi-touch input system.

3. The multi-user multi-touch input system of claim 1, wherein the controller is further configured to:

determine whether the first time and the second time are within an acceptable range; and

determine whether the particular user has touched the input portion at the particular location when it is determined that the first and second time are within said acceptable range.

4. The multi-user multi-touch input system of claim 3, wherein the acceptable range is about 10 milliseconds (10 ms).

5. The multi-user multi-touch input system of claim 1, wherein the controller is further configured to:

ignore touches detected by the touch-locator component when the user-identifier component does not detect a touch by one of the plurality of users, thereby allowing touches of non-users to be ignored.

6. The multi-user multi-touch input system of claim 1, wherein the controller is further configured to:

ignore one or more touches detected by the touch-locator component when within a determined time period the user-identifier component identifies two or more users that have touched the input surface.

7. The multi-user multi-touch input system of claim 1, wherein said controller is further configured to:

detect that the same user identified by the user-identifier component has touched the particular location multiple times during a determined period of time.

8. The multi-user multi-touch input system of claim 7, wherein the controller is further configured to detect that the particular user had held a constant touch at the particular location.

9. The multi-user multi-touch input system of claim 1, wherein the user-identifier component comprises:

at least one radio frequency (RF) generator; and

a plurality RF receivers capable of detecting RF energy from the RF generator, wherein for each of the plurality of users at least one RF receiver is provided to detect a change in the RF energy transmitted by the RF generator when a user touches the input portion of the multi-user multi-touch input system.

10. The multi-user multi-touch input system of claim 9, wherein the touch locator component includes an Acoustic Pulse Recognition (APR) or a capacitance touch screen configured to detect a touch at a particular location.

11. The multi-user multi-touch input system of claim 10, wherein the Acoustic Pulse Recognition (APR) touch screen or a capacitance touch screen are multi-touch screen capable of detecting multiple touches at the same time.

12. A computer-implemented method for providing a multi-user input system for use as input device by a plurality of users, said computer-implemented method comprising:

initiating a user-identifier component and a touch-locator component;

identifying, by the user-identifier component, a particular user of the plurality of users when the user-identifier component detects that the particular user has provided input to the multi-user input system;

providing to a controller a first indication indicating that a touch by the particular user has been detected at a first time by the user-identifier component;

identifying, by the touch-locator component, an input at a particular location of the multi-user input system;

providing to the controller a second indication indicating that a touch at a particular location has been detected at a second time by the touch-locator component;

reconciling, at the controller, the first and second indications to determine, based on the first and second times, whether the particular user has provided input to the multi-user input system at the particular location; and

reporting, at the controller, a touch by the particular user at the particular location of the multi-user input system.

13. The computer-implemented method of claim 12, wherein the reconciling of the first and second indications comprises one or more of the following:

determining timing information provided by the first and second indications,

determining whether multiple users have been identified within a determined period of time by said user-identifier component;

determining whether multiple input has been detected by the touch-locator component within a determined amount of time that the user-identifier component has identified the particular user; and

determining whether multiple input has been detected at the same location by said touch-locator component within a determined amount of time that the user-identifier component has indicated that one or more users have provided input.

14. A gaming apparatus for a plurality of players, comprising:

a touch-surface that serves as a common input area for playing a game by the plurality of players;

a user-identifier component configured to;

detect which one of the players has touched said common input area and communicate an identifier associated with the player to a controller, and

provide a first indication indicating that a touch by the player has been detected at a first time;

a touch-location component configured to;

detect a touch at a particular location of the common input area,

provide a second indication indicating that a touch at the particular location has been detected at a second time, and

receive from the user-identifier component the first indication,

receive from the touch-location component the second indication,

determine, based on first and second indications, whether the player has touched the input portion at the particular location of said common input area, and

generate as output indicating that the player identified by the user-identifier component has touched the common input area at the location indicated by the touch-location component when said determining determines that the player has touched the input portion at the location of the common input area.

15. A gaming apparatus as recited in claim 14, wherein the controller is provided by a gaming server that is in communication with the gaming apparatus.
