Investigation of Multiple Resource Theory Design Principles on Robot Teleoperation and Workload Management

To investigate whether a combination of audio and visual communication channels reduce workload and improve performance, we set up a test course and had a graphical interface (top left) for robot operators to control a robot for a search and threat-defusal task (red block as threat, see bottom left).

Robot interfaces often only use the visual channel. Inspired by Wickens’ Multiple Resource Theory, we investigated if the addition of audio elements would reduce cognitive workload and improve performance. Specifically, we designed a search and threat-defusal task (primary) with a memory test task (secondary). Eleven participants – predominantly first responders – were recruited to… Continue reading Investigation of Multiple Resource Theory Design Principles on Robot Teleoperation and Workload Management
