  • Patent number: 10057730
    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.

  • Publication number: 20070201432
    Abstract: A method and system for providing seamless mobility. The seamless mobility system includes a computer having at least a dial up modem and an Internet access port. The dial up modem is coupled to a first telephone network and the Internet access port is coupled to a high-speed Internet access point providing Internet access. A first telephone is coupled to the first telephone network to originate a call to a second telephone. The dial up modem detects and answers the call placed by the first telephone, the call is processed by the computer, and couples the call to the high speed Internet access point for delivery of the call over the Internet. The call is coupled through the Internet to deliver the call to a second computer or coupled through the Internet to a second telephone network to deliver the call to the second telephone.

  • Patent number: 6424707
    Abstract: A method and apparatus for establishing a point-to-point-to-point telephone connection between a remote telephone and a desired called telephone. The method and apparatus use a two-line base telephone unit, e.g., a home or office telephone, as an intermediary point in the telephone call to reduce long distance rates and/or to utilize features and/or information stored in the base telephone unit when the user is away from the home or office. In a first embodiment, the remote telephone makes a local call to the base telephone unit and instructs the base telephone unit to establish a telephone call with, and interconnect the remote telephone to, a called third party. In a second embodiment, the remote telephone makes a quick call to the base telephone unit instructing the base telephone unit to establish and interconnect both a telephone call back to the remote telephone and a second telephone call to the desired called telephone.
