Titel
Effects of bandwidth reduction of transmitted motion picture sequences on human recognition performance
Abstract
The Research Institute for Human Engineering (FAT) has been working in the field of land telerobot systems for the last six years. The main goal of current research work is the optimization of remote control and supervision of semiautomatic vehicles from a single control station for various missions. The research work done on a particular aspect of robot deployment in a driving task will be described in this paper. Robots are likely to be positioned at particular locations or to be moving in a terrain overlooking areas of military interest, such as likely enemy positions, contested areas, or supply lines. During the moving operation the robot is autonomous and ready to detect obstacles in a selected part of the landscape in front of it. After the robot is programmed with its mission there is no need for further radio communication until an obstacle is sensed which it cannot interpret because the automatic recognition system cannot recognize all threatening object situations for the driving task. 'Upon request', the vehicle requires help and support from humans. In this case the human acts as a remote controller and supervisor. In a remote control station he receives still pictures or picture sequences obtained from the vehicle over a communication channel.
