Design and Evaluation of Human-Centered Visualization Interfaces in Construction Teleoperation

Teleoperation is widely used in hazardous and uncertain site settings, allowing scheduled procedures to be carried out across long distances while workers are away from the sites. Teleoperators in off-sites collect both the site information and feedback from the interfaces which provide synthesized information that a robot collects. This interface mainly conveys visionary information for the operator's intuitiveness such as the spatial awareness of objects and surroundings. To achieve a rich visual understanding of the site, the interface should fully contain and intuitively convey the associated contextual information. Excessive or unintuitive information not only makes it difficult for operators to exert their full potential but also increases their cognitive load. This study explores how different visual interface configurations affect operators' work performance and their cognitive load during the teleoperation task. The findings from the experimental studies are expected to help develop human-centered interfaces for teleoperation in the context of construction tasks and provide the cornerstone for not only an intuitive but fruitfully informative interface in a provided task setting.
