VRP04_DESCR= This project will seek to address some issues of human- machine interaction. We will primarily be interested in the question of what adaptations occur when a human finds himself/herself dealing with a simulated environment as opposed to the real environment. We will be interested in the relationship between the human's perceived model of the simulated environment and the simulated graphical model. Interaction is composed of aspects of input devices which control the robot and also of viewing conditions. Input devices can vary in the ease of specification of the direction and speed of motion. The joystick (2 dof at each setting of a 3-way switch controls in total 6 joint angles of the robot), mouse (mimics action of joystick, controlled by cursor position on screen and switch setting selected by mouse buttons), and 6 dof Polhemus device will be used in turn as the input device. The viewing conditions may be non- immersive screen displays (can also incorporate different viewing angles, stereoscopic vision) or immersive (using hmd). We will seek to identify performance level (using measures such as time of completion or error count in completing the task) and also strategy (by tracking the changes of state of input device in the case of the mouse and joystick and by tracking hand motion trajectory in the case of the Polhemus). A hypothesis regarding the outcome of this comparison of the different interfaces is that the less sophisticated conditions (eg. joystick and non-immersive display) may prove their effectiveness to exceed that of the more complex interfaces using the Polhemus and immersive display.
