Human–Agent Teaming for Multirobot Control: A Review of Human Factors Issues

Abstract: The human factors literature on intelligent systems was reviewed in relation to the following: efficient human supervision of multiple robots, appropriate human trust in the automated systems, maintenance of human operator's situation awareness, individual differences in human-agent (H-A) interaction, and retention of human decision authority. A number of approaches-from flexible automation to autonomous agents-were reviewed, and their advantages and disadvantages were discussed. In addition, two key human performance issues (trust and situation awareness) related to H-A teaming for multirobot control and some promising user interface design solutions to address these issues were discussed. Some major individual differences factors (operator spatial ability, attentional control ability, and gaming experience) were identified that may impact H-A teaming in the context of robotics control.

Theory and evaluation of human robot interactions

Abstract: Human-robot interaction (HRI) for mobile robots is still in its infancy. Most user interactions with robots have been limited to tele-operation capabilities where the most common interface provided to the user has been the video feed from the robotic platform and some way of directing the path of the robot. For mobile robots with semiautonomous capabilities, the user is also provided with a means of setting way points. More importantly, most HRI capabilities have been developed by robotics experts for use by robotics experts. As robots increase in capabilities and are able to perform more tasks in an autonomous manner we need to think about the interactions that humans will have with robots and what software architecture and user interface designs can accommodate the human in-the-loop. We also need to design systems that can be used by domain experts but not robotics experts. This paper outlines a theory of human-robot interaction and proposes the interactions and information needed by both humans and robots for the different levels of interaction, including an evaluation methodology based on situational awareness.

Television schedule system with access control

Abstract: The present invention is directed to a television schedule system (1) with a user interface (38) which allows a user to control access to television programs by, time rating, content, and/or channel. Furthermore, the user may set a limit on pay-per-view (PPV) spending to limit the purchase of PPV programs.

Interactive entertainment network system and method for providing program listings during non-peak times

Abstract: An interactive entertainment network system has a program provider, multiple user interface units in individual homes, and a distribution network interconnecting the program provider and the user interface units. The program provider has a storage medium containing a plurality of program data records which contain programming information about the programs provided by the program provider. An electronic program guide (EPG) executes on each user interface unit. The EPG requests the program data records from the storage medium at the program provider and displays the programming information contained in the program data records. To prevent burdensome demand during certain high activity peak time when a plurality of the electronic program guides are likely to concurrently request the program data records, the program provider transmits at least some of the program data records to a plurality of the user interface units prior to a peak time. The program provider initiates this transmission on its own, and not in response to a request from any EPG. The user interface units store the program data records in a record cache for use by the EPG during the ensuing peak time. In this manner, the EPG can display the programming information contained in the stored program data records during the peak time, rather than requesting the information from the program provider.

ICrafter: A Service Framework for Ubiquitous Computing Environments

Abstract: In this paper, we propose ICrafter, a framework for services and their user interfaces in a class of ubiquitous computing environments. The chief objective of ICrafter is to let users flexibly interact with the services in their environment using a variety of modalities and input devices. We extend existing service frameworks in three ways. First, to offload services and user input devices, ICrafter provides infrastructure support for UI selection, generation, and adaptation. Second, ICrafter allows UIs to be associated with service patterns for on-the-fly aggregation of services. Finally, ICrafter facilitates the design of service UIs that are portable but still reflect the context of the local environment. In addition, we also focus on the system properties such as incremental deployability and robustness that are critical for ubiquitous computing environments. We describe the goals and architecture of ICrafter, a prototype implementation that validates its design, and the key lessons learnt from our experiences.
