Understanding Human Factor Issues of the Shared Control System: a literature review

Abstract

The aim of this study is to identify human factor issues related to the shared control system. With the rapid development of machine and robot technology, an enormous number of system introduces the human-machine cooperation to reduce physical and psychological workload. In the shared control system, which is one type of the human-machine cooperation, the machine agent senses the environment and then autonomously takes the initiative to choose its activity responding to the environment. There are many human factor issues in this kind of system. However, most of the research on the shared control system is focused on the performance improvement of the machine, not on human factor issues. Literature review was conducted to collect and understand the academic literature that containing information about the shared control system. The topic varies from defining the shared control system to evaluating the system. Collected problems and guidelines are classified from the perspective of the human agent. Control authority, trust, workload and performance are frequently appeared issues. In addition, it is found that there are relationships between issues. By considering the derived human factor issues in the system design step, it is possible to develop more effective the shared control system. The result of this study can be applied to other types of human-machine cooperation system.
