Robot tracing (2005)

Adams, J. A. (2005). Human-Robot Interaction Design:Understanding User Needs and Requirements, In Proceedings of the 2005 Human Factors and Ergonomics Society 49th Annual Meeting, September 2005.


In contrast to the previous paper (Robot), this paper uses robots to help in the safety and rescue missions. Author was working in cooperation with the Nashville Metro Police department's Bomb Squad and the Nashville Metro Fire Department’s HAZMAT team. Their aim is to let robots do the job instead of humans. Another goal is to advance Human-Robot Interaction (HRI) research by allowing single human to supervise large number of robots (up to 100 robots). With the current robot design, human can only supervise up to 5 robots at a single time! Author argue that the current robot design needs to be changed to accommodate that initiative. Later, they discussed the initial movement for to change the design of robots to be a Human Centred Design (HCD).

For their multi-robot design to be controlled by single human, they needed to employee Situation Awareness (SA) when designing their robots. SA is a representation of the human understanding of the current situation around him/her and the upcoming consequences in the future.

They used GDTA to identify robot operator to identify: basic goals, major goals, and SA requirements. In their methodology, they started by obtaining HRI SA requirements as its the core part of this work. In order to do that, they used GDTA and SA principals to help them in identifying and modeling the UCD and SA requirements. Since they're working in the field of CBRNE search and rescue domain, they started in two directions: (a) interviewing domain experts to gain a generic understanding of the rescue field, and (b) exploring the supporting document that was provided to them by Nashville Metros Bomb Squad. The previous directions helped them to identified the basic high-level goals and action steps in this field. Their next future step was to use their resulted high-level requirements analysis, and conduct a more focused interviews, and observations to sterengthen their requirements and detailed them.

This work still in its early stages, thus a preliminary results were only discussed on this paper. They provided a goal hierarchy for the communication, in addition to the special task force tasks breakdown. Author, discussed the communication as an essential part of their analysis, he indicated that communication can be very different from a robot controlled to human. For example, a human does not need to communicate while navigating a building, while on the other hand, robot needs to do so.
