Abstract

A method and apparatus for providing a virtual push-to-talk (PTT) button is provided herein. During operation, an augmented reality and object recognition circuitry will detect user'"'"'s fingers and a free surface near the fingers by analyzing image captured by camera. A virtual PTT button is placed upon an object that is near to user'"'"'s finger. Gesture recognition will be performed by the circuitry to determine if a user presses the virtual PTT button. When a user presses the virtual PTT button, the circuitry identifies the action and transmits a message to a PTT radio, causing the PTT radio to activate a PTT call.

Claims

1. An augmented-reality system comprising:

circuitry configured to detect a location of a user'"'"'s hand or fingers;

a projector configured to project a virtual PTT button onto eyeglasses, and in a position so that the virtual PTT button appears at a location based on the location of the user'"'"'s hand or fingers, wherein the virtual PTT button is not visible unless viewed through the eyeglasses;

a transmitter; and

the circuitry configured to detect when a user presses the virtual PTT button and instruct the transmitter to transmit a PTT signal to a radio upon the detection that the user has pressed the virtual push-to-talk button.

2. The system of claim 1 wherein the push-to-talk signal causes the radio to enter a ½

-duplex mode of operation.

3. A method comprising the steps of:

detecting a location of a user'"'"'s hand or fingers;

projecting a virtual PTT button onto eyeglasses, the virtual PTT button projected at a position so that the virtual PTT button appears at a location based on the location of the user'"'"'s hand or fingers, wherein the virtual PTT button is not visible unless viewed through the eyeglasses;

detecting when the user presses the virtual push-to-talk button; and

transmitting a wireless push-to-talk signal to a radio upon the detection that the user has pressed the virtual push-to-talk button.

4. The method of claim 3 wherein the push-to-talk signal causes the radio to enter a ½

-duplex mode of operation.
