Shuttle MIDAS - MIDAS Screen LayoutIn this scenario we see four screens (called viewer windows) related to an operator agent's environment (MIDAS has implemented JACK® as the agent operator in this instantiation). There are four viewer windows in this scenario of the agent as he monitors the cockpit of the Space Shuttle. Starting in the top left, we can see a window of the agent's profile and crewstation as he visually scans the interior environment. The top right screen demonstrates the view from the agent's eyes. This screen demonstrates the operator agent's interior visual scan pattern and fixation points. Changes in the environment get encoded by the agent and update the world representation if the information falls within his attention cones. These changes also trigger workload associated with respective tasks and procedures that the agent is performing. The bottom right screen indicates the workload output along a six-channel representation of workload as the agent deals with the environmental events. The six channels of workload include visual input, auditory input, spatial cognitive processing, verbal cognitive processing, motor output, and voice output. The bottom left viewer window demonstrates the agent's Situation Awareness (SA). This is calculated by taking a calculation (ratio) of perceived SA versus actual SA. Generally speaking this perceived will be lower than the actual SA as the theory upon which this is based indicates that people generally think they know more about their surroundings than they actually do know (see Shively, Brickner & Silbiger, 1997).
