Martinson, Eric and Brock, Derek (2007): Improving human-robot interaction through adaptation to the auditory scene. In: Proceedings of the ACM/IEEE International Conference on Human-Robot Interaction 2007. pp. 113-120.

“Effective communication with a mobile robot using speech is a difficult problem even when you can control the auditory scene. Robot ego-noise, echoes, and human interference are all common sources of decreased intelligibility. In real-world environments, however, these common problems are supplemented with many different types of background noise sources. For instance, military scenarios might be punctuated by high decibel plane noise and bursts from weaponry that mask parts of the speech output from the robot. Even in non-military settings, however, fans, computers, alarms, and transportation noise can cause enough interference that they might render a traditional speech interface unintelligible. In this work, we seek to overcome these problems by applying robotic advantages of sensing and mobility to a text-to-speech interface. Using perspective taking skills to predict how the human user is being affected by new sound sources, a robot can adjust its speaking patterns and/or reposition itself within the environment to limit the negative impact on intelligibility, making a speech interface easier to use.”

Martinson, Eric and Brock, Derek (2006): Auditory perspective taking. In: Proceedings of the 1st ACM SIGCHI/SIGART Conference on Human-Robot Interaction 2006. pp. 345-346.

“Auditory perspective taking is the process of imagining the auditory scene from another's place and inferring what that person can (and cannot) hear, as well as how this affects his or her auditory comprehension. With this inferred knowledge, a conversational partner can then adapt his or her vocal presentation to overcome or cope with competing sounds and other auditory challenges to ensure that what is being said can be understood. In this poster, we explore several aspects of auditory perspective taking in the context of a robot speech and listening interface.”

Brock, Derek, Hix, Deborah, Dievendorf, Lynn and Trafton, J. Gregory (1995): Extending the User Action Notation for Research in Individual Differences. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 253-257.

“Software user interfaces that provide users with more than one device, such as a mouse and keyboard, for interactively performing tasks, are now commonplace. Concerns about how to represent individual differences in patterns of use and acquisition of skill in such interfaces led the authors to develop modifications to the standard format of the User Action Notation (UAN) that substantially augment the notation's expressive power. These extensions allow the reader of an interface specification to make meaningful comparisons between functionally equivalent interaction techniques and task performance strategies in interfaces supporting multiple input devices. Furthermore, they offer researchers a new methodology for analyzing the behavioral aspects of user interfaces. These modifications are documented and their benefits discussed.”
