Paper Desperately Seeking Simplicity: How Families with Young Adults with Cognitive Disabilities Adopt Assistive Technologies [Best of CHI Nominee]
Melissa Dawe

HCI, with its roots in Human Factors Engineering has traditionally been focused on efficiency and task completion. Lately, though, there is recognition that the affective aspects of human-machine systems play a role in the users' experience of a system, as well as having important implications for the usability of interfaces. Drawing on a tradition of psychological work on belief and affect, the speakers in this session present papers on how the affective aspects of interfaces can improve interaction, and how to measure and use affect in designing interfaces.

Paper Can a Virtual Cat Persuade You? The Role of Gender and Realism in Speaker Persuasiveness
Presents findings revealing how virtual characters are as persuasive as real people and that cross-gender interactions transfer to virtual speakers. Explains how virtual characters can be exploited for persuasive interfaces.
Catherine Zanbaka, Paula Goolkasian, Larry Hodges

Paper The Sensual Evaluation Instrument: Developing an Effective Evaluation Tool
Describes an instrument for collecting real-time self-assessment of affect. Portable, may work across cultures, offers consistency and flexibility. Can help elicit emotional feedback quickly and easily during the design process.

How can we understand presence in absence?
This research investigated intimacy through cultural probes and contextual inquiry

• Contact is supported by communication acts (saying I m thinking of you)
• Content express the relationship in substance and form
• Context

The Cube is a single shared object between partners used for quick messaging. It uses symbols to represent expression and personal effort through creativity.

Using Linguistic Features to Measure Presence in Computer-Mediated Communication
Presents a new technique for measuring presence in computer-mediated communication using linguistic features of dialogues. Provides an easy-to-use method for assessing the effects of communications technologies on presence.

Adam Kramer
Lui Min Oh
Susan Fussell

Presence is rarely measured in computer-mediated communications and the typical measures of presence are either retrospective or too intrusive.
The study make the hypothesis that people use different words to describe their presence based on their feeling of persence and co-location.
Based on their conclusions, the self-reported presence can be predicted by a small number of linguistic features. Therefore, linguistics markers can be used to measure presence, even if performed after the facts in a video-conferencing session.

The Paradox of the Assisted User: Guidance can be Counterproductive
This paper contributes to the empirical and cognitive foundation of principles underlying human computer interaction. It shows that guidance in interfaces by externalizing information does not always yield better performance.

This paper discusses externalizing information required to run tasks by providing guiding interfaces does not always yield better results. Having information externalized tempt users to not learn what they need to do. This study used the simulation of a conference planner to test the impact of externalization vs internalization of information related to tasks.
The "external" version showed the participants the timeslots where they could place a particular speaker while the "internal" version did not have this information available.
The "internal" version took longer to complete and require less superflous moves but users of this version used "smart strategy" more often and felt less lost. Users of the "internal" version scored higher in terms of declarative knowledge.

This session continues the conversation of deviant behavior in online communities from the original 1994 session. The bulk of this panel session took the format of panelists giving their input to scenarios raised by the facilitator and elicited from the audience members as well.

Some of the issues that were raised in the panel were:
- laws and norms of online communities vary widely depending on the communities being served.
- not all deviant behavior is the same and sometimes the boundaries between legitimate deviant behavior is not clear.
- general avoidance of the term deviant and the parallels between the situation involving graffitti in cities
- whether victims/perpetrators of deviant behavior are allowed to speak out
- the issue of whether social justice can take place in online communities that are mostly owned

The CHI design community is concerned, in one way or another, about the question of how to better incorporate a meaningful and productive dialogue about design work into the conference culture of CHI. There was a general vibe of frustration in the room regarding the difficulty of getting design work accepted in paper form, and this led to questions about whether the current reviewing panels really include enough people who know enough about design to offer a fair and informed critique. David Gilmore and the other committee representatives charged the people in the room to step up to that challenge, saying that they had an incredibly difficult time finding designers who were willing to serve as reviewers this year, so pointing the finger at CHI is not entirely fair.

This challenge seemed to be fairly well received, but other issues arose, including

• frustration with Experience Reports because some tenure committees are apparently not valuing them at the same level as short papers, so researchers feel pressured to avoid them


• frustration with the difficulty of presenting work from the practitioner's perspective - seeing the real process that people go through, and presenting work that is interesting even if there isn't time to write a paper about it


• the question of the relationship between CHI, DUX, and DIS -- what sort of work should be done where? What happens when individuals are required to choose one over the others? If designers feel excluded from CHI publication, and migrate to the more specialized conferences as a result, what will that do to the CHI vibe?

Sorry this is a bit late. I had some technical difficulties. :)

This panel was a discussion of the trend towards the formation of "I-Schools": schools of Information, Informatics, Information Science, or some similar derivative of the "I" word, and the issues that this trend raises for the CHI community as a whole. As HCI matures and becomes more institutionalized, we need to consider what sort of institution we want to be, and this panel was about exploring that question. The panelists were representatives of I-Schools from around the world - John Carroll (Pennsylvania State, US), Paul Dourish (University of California - Irvine, US), Batya Friedman (University of Washington, US), Masaaki Kurosu (Soken-dai, Japan), Gary Olson (University of Michigan, US), and Alistair Sutcliffe (University of Manchester, UK).
The main ideas that the panelists raised were that:

• I-schools explicitly focus on the intersection of information, people, and technology, which leads to a more central role for HCI than is usually the case in schools of Computer Science or Engineering.


• I-schools are interdisciplinary in nature, which:


• provides a supportive and rich work environment within the school itself


• encourages faculty and students to take a broad perspective -- asking a wide range of questions, drawing on a wide range of theories, and reaching out to other areas of the university in order to deepen their work.




• As independent units within the university, I-schools have a high level of autonomy, which gives HCI an institutional clout that it usually does not have when it is a less central component of a larger school.


• I-Schools raise questions regarding the evolution of the relationship between HCI and CS, and not all of these questions are easy or pleasant.
