ABSTRACT
Introduction：Coming from the point of emergency room environment, this research studies the motion behavior, the control panel conformation, and the virtual operating movements of surgical nursing staff in the emergency room, in order to provide a reference for instrument design. Method：
The research began with professional interviews, followed by experiments on hand motion of surgical nursing staff in the emergency room. Test participants consist of surgical nursing staff from emergency rooms and the surgical department. A total of 20 participants, 10 females from each department were chosen to take the tests. The research is divided into three categories: (1) The study of wrist joint angle (flexion, extension) during contact with existing control panels. (2) Controlling existing panel buttons in a 66 degree angle to the panel from three directions (left, middle, right). (3) Controlling existing panel buttons in a 66 degree angle to the panel from three directions (left, middle, right) under virtual conditions. Results：Results of this study presented a difference in operation height range between different control panel directions amongst emergency room and non-emergency room surgical nursing staff. In the analysis of variance, the three sets of relationships of the three control directions, actual and virtual control, and emergency room and non-emergency room surgical nursing staff were analyzed against the angles presented in a simple factor variance analysis. The angle presented in the interaction of actual and virtual control in the three directions reached significant level; a significant level was also reached amongst the participants. The interaction between actual and virtual control and emergency surgical and non-emergency surgical also reached significant level, however, the effects amongst participants did now reach significant level. Discussion：From the results we can see that participants with the same height do not necessary present the same wrist angles. Significant difference between actual and virtual controls of emergency surgical staff only came from operations from the right hand side; no significant differences were found in the actual and virtual controls from the middle and the left. As for non-emergency room surgical staff, significant difference occurred in the actual and virtual control from the left and the middle, while no significant difference were presented in the experiment from the right side.
