An examination of how existing technologies support mutual eye gaze between humans and an avatar

Future warfare concerns information superiority, i.e. supplying decisionmakers with better information than their opponents. Their decisions will be based on information from various sensors such as radars, UAVs, satellites, or any other object that can supply the decision makers with information. A system like this will make use of a huge amount of data, and the decisionmakers may not be able to handle all information that will be presented to them. Because of this, they might make decisions that are not optimal for the task. To enhance tha capability in decision making, the national defence college will create an avatar which will be located in a 3D presentation device, called the Visioscope (tm). If the computer system detects that a person might have made an erroneous decision, the avatar will act and point out the error, i.e. there will be a dialog between the decision makers and the avatar. One important factor when humans communicate with each other is mutual eye gaze. If mutual eye gaze can occur between the users and the avatar, and if the avatar can behave like a human, the communication process will be improved and the users will make less errors. This literature study aims to generate some ideas about how existing technology supports mutual eye gaze between the avatar and the users in the ROLF 2010 environment. The study partly concerns how a computer system can control an avatar so that it behaves like a human
