Abstract
Currently, there is considerable interest related to the use of computer games as simulators for training. One of the issues with using computer simulations is that the controls should be simple and natural enough that the trainee can focus on the training rather than on complicated simulator controls. The current research examined two versions of a game based simulator for training Soldier tasks in an urban environment. One version employs a common desktop computer interface, while the second version has the computer components, controls, and the display embedded into Soldier field equipment so that the simulator is wearable by the trainee. A heuristic usability evaluation of the two simulators was conducted to determine the ease of use of the controls and displays. The results found the wearable simulator to have more usability concerns than the desktop computer. These findings can be used to improve future simulator interfaces, particularly those employing novel controls that differ from traditional desktop computer interfaces.
