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.
