## 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

### Claim 1

A system comprising:
(a) a finger-wearable sleeve comprising:
a force sensing actuator,
an infrared (IR) laser,
an IR light-emitting diode (LED), and
a controller configured to:
(i) trigger the IR laser when the force sensing actuator senses a pinching of thumb to finger, and
(ii) trigger the IR LED when the force sensing actuator senses a touching of a screen;
(b) an IR camera; and
(c) a controller associated with the IR camera and 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:
(i) 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
(ii) 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.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the first input functionality is a drag-and-drop functionality, wherein:
dragging starts at a location on the screen where the pinching initiates; and
dropping occurs at a location on the screen where the pinching ceases.

### Claim 3 (depends on 1)

The system according to claim 1, wherein the first input functionality is a swiping or scrolling functionality, wherein:
swiping or scrolling start at a location on the screen where the pinching initiates; and
swiping or scrolling end at a location on the screen where the pinching ceases.

### Claim 4 (depends on 1)

The system according to claim 1, wherein the second input functionality is a clicking functionality.

### Claim 5 (depends on 1)

The system according to claim 1, wherein said force sensing actuator comprises:
a capacitor configured to sense the pinching; and
a physical control configured to sense the touching.

### Claim 6 (depends on 1)

The system according to claim 1, wherein said IR laser is positioned such that it emits its IR beam substantially along a longitudinal axis of said finger-wearable sleeve.

### Claim 7 (depends on 1)

The system according to claim 1, wherein said IR LED is positioned such that it emits its IR beam substantially perpendicularly a longitudinal axis of said finger-wearable sleeve.

### Claim 8 (depends on 1)

The system according to claim 1, wherein:
said finger-wearable sleeve further comprises a radio-frequency (RF) transmitter; and
the system further comprises an RF receiver coupled to said controller that is associated with the IR camera.

### Claim 9 (depends on 8)

The system according to claim 8, wherein:
said finger-wearable sleeve further comprises a touch-sensitive electronic pad;
said controller of said finger-wearable sleeve is further configured to transmit signals from said RF transmitter to said RF receiver, wherein the signals are indicative of motion of a thumb over said touch-sensitive electronic pad; and
said controller that is associated with the IR camera is further configured to trigger a scrolling functionality in the host computer, wherein the scrolling is based on the motion of the thumb over said touch-sensitive electronic pad.

### Claim 10 (depends on 1)

The system according to claim 1, wherein said IR camera is directed towards the screen, such that visual content is within a field of view of the IR camera.

### Claim 11 (depends on 1)

The system according to claim 1, wherein said controller that is associated with the IR camera is further configured to communicate with said host computer by way of masquerading as a computer mouse that triggers the first and the second input functionalities.

### Claim 12 (depends on 1)

The system according to claim 1, wherein said controller that is associated with the IR camera is further configured to facilitate calibration of the system, wherein:
the host computer utilizes the visual content projector to project visual indications onto the screen;
the finger-wearable sleeve is utilized to touch the screen where the visual indications appear; and
said controller that is associated with the IR camera correlates coordinates of where the IR camera detects the touches of the finger-wearable sleeve with coordinates of the visual indications.
