In mission critical communications, speed, accuracy, and visibility of information are necessary for success. The CONTEX® GTX, which is a user interface specifically designed for voice consoles in U.S. air defense operations centers, takes a technological leap forward by enabling users to customize voice console screens with background text, images and colors. This customization provides operators with important contextual information and gives more meaning to their displays. For example, background maps can show geographic locations of radios. Speed-dial buttons can be placed over a control room map, giving the ability to quickly dial other operators. Mission-specific instructions can be pushed to users in real time. The GTX greatly enhances user experience in any mission voice system where a large number of voice assets must be managed.
