Explaining voice characteristics to the deaf is not an easy undertaking for their instructors. Furthermore, many existing strategies for conveying these characteristics and teaching the deaf how to perceive them do not seem efficient, especially when dealing with the concept of pitch. As a result, some deaf people are not fully capable of differentiating between voice characteristics. Paradoxically, this doesn.t only apply to the deaf, but many of the hearing do not know the difference between pitch and loudness; when asked to generate a higher-pitched sound, many generate a louder sound. These were some of several reasons that led to my exploration of additional approaches to the visual representation of voice. I developed and employed non-speech voice-controlled applications in analyzing the interaction patterns of seven deaf children. The aim was to explore the potential role of paralinguistic vocal control of interactive media in enabling the deaf to have a greater understanding of voice and to offer their instructors more efficient and engaging strategies for explaining voice characteristics.

We are designing a feedback system to encourage more fuel-efficient driving habits among school-bus drivers. We chose to design for the school bus because as one of the largest public transport systems in the U.S., it is a major contributor to the country's total fuel consumption and pollutant emissions. Our design uses persuasive technology to discourage excessive idling and aggressive driving by providing real-time in-vehicle feedback for self-monitoring.

We are in the midst of an explosion of emerging human-computer interaction techniques that have redefined our understanding of both computers and interaction. We propose the notion of Reality-Based Interaction (RBI) as a unifying concept that ties together a large subset of these emerging interaction styles. Through RBI we are attempting to provide a framework that can be used to understand, compare, and relate current paths of HCI research. Viewing interaction through the lens of RBI can provide insights for designers and allows us to find gaps or opportunities for future development. Furthermore, we are using RBI to develop new evaluation techniques for features of emerging interfaces that are currently unquantifiable.

Recently, researchers have been working to bring the benefits of rigorous software engineering methodologies to end users who find themselves in programming situations, to try to make their software more reliable. End users create software whenever they write, for instance, educational simulations, spreadsheets, or dynamic e-business web applications. Unfortunately, errors are pervasive in end-user software, and the resulting impact is sometimes enormous. This special interest group meeting has three purposes: to bring the results of a recent (February 2007) week-long "Dagstuhl" meeting on end-user software engineering to interested researchers at CHI; to incorporate attendees' ideas and feedback into an emerging survey of the state of this interesting new subarea; and generally to bring together the community of researchers who are addressing this topic, with the companies that are creating end-user programming tools.

This study combines quantitative (target acquisition tasks, subjective ratings and a simple reaction time test) and qualitative (interview) methods to arrive at a more nuanced understanding novice users. experience over time. The progress of training of ten participants has been observed. The study shows that the performance improved over time and plateaued on day four of the five days of the study.

In this paper we investigate the effect of search engine brand (i.e., identifying name that distinguishes a product from its competitors) on evaluation of system performance. Our research is motivated by the large amount of search traffic directed to less than a handful of Web search engines, even though many are of equal technical quality with similar interfaces. We conducted a laboratory experiment with 32 participants measuring the effect of four search engine brands while controlling for the quality of search engine results. Based on average relevance ratings, there was a 25% difference between the most highly rated search engine and the lowest, even though search engine results were identical in both content and presentation. We discuss implications for search engine marketing and the design of empirical studies measuring search engine quality.

In this paper we make the case for the existence and importance of a special class of email user, the high-throughput email user, whose needs are not well-served by current clients. We establish these groups by quantitative and qualitative definitions derived from fieldwork, a large-scale survey, and subsequent analysis of the user population, along with analysis of current email clients. We conclude with directions for future research.

Wikis provide a simple and unique approach to collaborative authoring, allowing any member of the community to contribute new, or change existing information. However, Wikis are typically disconnected from the physical context of users who are utilizing or creating content, resulting in suboptimal support for geographic communities. In addition, geographic communities might find the highly skewed generation of content by a few individuals problematic. Here we present research into addressing these challenges through location-awareness and lightweight user content rating mechanisms. We describe one such location-aware Wiki, CampusWiki and initial results from a field study demonstrating the value of location-linked content and the rating approach. We conclude with a discussion of design implications.

In this paper we discuss the problems faced when trying to design an evaluation protocol for a multimodal system using novel input modalities and in a new domain. In particular, we focus on the problem of trying to minimize bias towards certain modalities and interaction patterns. Such bias might be introduced by experimenters in the instructions given to users which explain how the system can be used.
