We examine the role of self-shaping and commitment devices in persuasive systems. Self-shaping refers to the practice of taking purposeful action in modifying one's environment in order to shape or influence one's own future behavior. We present results from a survey of 23 users that assessed the role self-shaping plays in their use of persuasive technologies. A second survey elicited 65 self-shaping designs from 41 expert users, finding the Fogg Behavior Model describes how the designs were indeed persuasive. We then reviewed 85 tools based on this model to show the two dimensions that can be used to organize persuasive devices: (1) salience of a tool's self-shaping features and (2) their intended flexibility. The resulting four categories of tools are useful for researchers and designers of persuasive systems.
This paper addresses how children can collab.rate by leveraging the ubiquity of mobile devices. Specifically we investigate how children (ages 8 - 9) read and share children's stories using two collab.rative confi...

The elder population is rising worldwide;in the US, no longer being able to drive is a significant marker of loss of independence. One of the approaches to helping elders drive more safely is to investigate the use of automotive user interface technology, and specifically, to explore the instrument panel (IP) display design to help attract and manage attention and make information easier to interpret. In this paper, we explore the premise that dashboard displays can be better designed to support elder drivers, their information needs, and their cognitive capabilities. We conducted a study to understand which display design features are critically linked to issues of divided attention and driving performance. We found that contrast of size and reduced clutter are instrumental in enhancing driving performance, particularly for the elder population. Surprisingly, our results showed that color elements have a negative effect on driving performance for elders, while color elements and fills slightly improve performance. We conclude with design implications generated from this work. Copyright 2011 ACM.

The rapid growth of human computation within research and industry has produced many novel ideas aimed at organizing web users to do great things. However, the growth is not adequately supported by a framework with which to understand each new system in the context of the old. We classify human computation systems to help identify parallels between different systems and reveal "holes" in the existing work as opportunities for new research. Since human computation is often confused with "crowdsourcing" and other terms, we explore the position of human computation with respect to these related topics. Copyright 2011 ACM.

TeslaTouch is a technology that provides tactile sensation to moving fingers on touch screens. Based on TeslaTouch, we have developed applications for the visually impaired to interpret and create 2D tactile information. In this paper, we demonstrate these applications, present observations from the interaction, and discuss TeslaTouch's potential in supporting communication among visually impaired individuals.

Children who are not co-located with system developers because of geographic location or time zone difference have ideas that are just as important and valid as children who are easily "availab.e". This problem is the motivation for my thesis work. I propose to design, develop, and research a computer-mediated, geographically distributed, asynchronous tool to facilitate intergenerational participatory design.
In this paper, a valid frequency range of throat signal analyses is presented. Compare to speech signals, the throat signals have many differences in the amount of information. In this context, targeting on throat sig...
