[Effects of digital information display time on human and machines monitoring performance].

Objective: To provide an index for function allocation of information monitoring between human and machine by studying the effect of digital information display time on human or machine monitoring performance.

Method: Two computers were used. One computer, ten numbers with two decided digits were displayed randomly for three times.

[Experimental study on human reaction of determination and performance in virtual environment].

Objective: To study factuality of ergonomic experimental data from subjects performing virtual environment wearing head mounted display (HMD) and data gloves, so as to improve the reliability of the application of virtual reality in manned spaceflight (e.g. human-machine interface design scheme ergonomic evaluation, and virtual training).
