One aim of a telepresence system is to make users? collaborations become more
natural and gives a more ?accurate? sensation of nearness to the people who are
interacting with other people through the system. There are many factors that can
directly influence people?s perceptions about telepresence systems. This thesis
helps to find out what typical factors are and how they can influence the perceptions
of telepresence systems.
One of the most important factors that influences the quality a telepresence
system is delay. Hence, in order to have a control of the delay, a telepresence
experimental model was established, and a serous of tests had been carried out
with the model. Based on the measurement results, we can conclude that the
optical delay is directly related to the frame rate of the camera and the refreshing
rate of the screen.
In addition, a lot of stimulus-reaction time measurements had been done.
Based on the test results, we got indications that the perception and reaction time
is directly involved with age, tiredness, and concentration of the people using the
system. The perception and reaction time does not seem to correlate with the
education of the people using the system.
Finally, in order to find out whether the space perception can influence the perception
and reaction time, two stereoscopic system models had been constructed.
A lot of pilot tests had been done with the model. According to the measurements,
we can conclude that with the same contents and same frame rates of videos, the
perception and reaction time with 3D videos seem to be shorter than that with 2D
