Abstract

A system having a finger-wearable sleeve having an IR light-emitting diode (LED), an IR camera; and a controller associated with the IR camera. The controller is configured to communicate with a host computer that utilizes a visual content projector to project visual content onto the screen. And based on signals received from the IR camera (1) trigger a first input functionality in the host computer, wherein the first input functionality is based on a location on the screen where an IR beam from the IR laser impinges, and (2) trigger a second input functionality in the host computer, wherein the second input functionality is based on a location on the screen near where an IR beam from the IR LED is emitted.

Claims

1. A system comprising:

at least two hand-operable devices, each comprising;

a button,

a light source,

a radio frequency (RF) transmitter, and

a controller configured to transmit a command via said RF transmitter responsive to said button being pressed;

a camera;

an RF receiver; and

a computer associated with said camera and said RF receiver, wherein said computer is configured to;

cause a screen to display visual content,

detect, using said camera;

the light emitted by said light sources, and

locations from which said light sources emit the light,

receive the commands via said RF receiver,

trigger different input functionalities in said computer based on;

the received commands, and

the detected locations from which said light sources emit the light.

2. The system according to claim 1, wherein:

each of said hand-operable devices comprises one or more components selected from the group consisting of;

an accelerometer, and a gyro; and

the computer is configured to trigger the different input functionalities also based on readings of said one or more components.

3. The system according to claim 2, wherein one of the different input functionalities is a cursor position control functionality that moves the cursor position on the screen responsive to motion of at least one of said hand-operable device, wherein the motion is determined by:

the detecting changes in the location from which said light sources emit the light; and

the readings of said one or more components.

4. The system according to claim 1, wherein one of the different input functionalities is a cursor position control functionality that moves the cursor position on the screen responsive to motion of at least one of said hand-operable device, wherein the motion is determined by the detecting changes in the location from which said light sources emit the light.

5. The system according to claim 1, wherein one of the different input functionalities is a clicking functionality.

6. The system according to claim 5, wherein the clicking functionality is applied at a location in the displayed digital content that corresponds to a location from which at least one of said light sources emits the light when the respective command is received.

7. The system according to claim 1, wherein:

10. The system according to claim 1, wherein one of the different input functionalities is:

a gesture mode that activates a specific operation in said computer based on a path of motion of at least one of said hand-operable devices,

wherein the motion is determined by the detecting changes in a location from which said light sources emit the light.

11. The system according to claim 10, wherein said computer is further configured to record multiple ones of the paths of motion, and to associate each of the paths of motion with a different one of multiple ones of the specific operation.

12. The system according to claim 2, wherein one of the different input functionalities is:

a gesture mode that activates a specific operation in said computer based on a path of motion of at least one of said hand-operable devices,

wherein the motion is determined by reading of said one or more components.

13. The system according to claim 12, wherein said computer is further configured to record multiple ones of the paths of motion, and to associate each of the paths of motion with a different one of multiple ones of the specific operation.
