Drummers and non-drummers alike can often be seen making percussive gestures on their chests, knees and feet. Ubiquitous Drums enhances this experience by providing musical feedback for these and other gestures. This paper describes the implementation and evolution of this tangible, wearable musical instrument. © 2010 Copyright is held by the author/owner(s).

Street art and political activism have a rich history of shaping urban landscapes. Our work explores the processes by which public artists and political activists contribute to public spaces, introducing opportunities for HCI researchers to engage with the people who shape the aesthetic feel of our cities. We present WallBots-autonomous, wall-crawling robots as a research probe for public expression across a wide range of surfaces and hard-to-reach places, including bus stops, whiteboards, streetpoles, trashcans, moving vehicles and building walls. We evaluate WallBots as a low-cost DIY authoring tool for public artists and activists. Our study of six individuals who extensively contribute to public spaces offers insights into the materials and practices behind grassroots public expression. We then leverage feedback from participants, among them a graffiti artist, light painter, political activists, and street musician, to evaluate interaction techniques for manipulating WallBots as a medium for public expression across a range of surfaces. Our findings expose a research space for technological interventions in the context of street art, and we conclude with design insights for magnetic kinetic systems as an approach for supporting engagement, expression and creativity in public spaces. © 2010 ACM.

Fast and effective communication is crucial during medical emergencies, but patients' disabilities can make it a challenging task for emergency medical responders. This paper proposes a mobile system to deal with the communication barrier between medical responders and deaf patients. The system allows medical responders to quickly browse a collection of emergency-related sentences, and show videos of the corresponding translations in sign language to the deaf patients. The design process involved experts in emergency medicine as well as experts from the deaf community. The evaluation carried out on ten emergency medical responders and ten deaf subjects showed that the system is useful to support communication with deaf people during medical emergencies. © 2010 ACM.

As an important approach to ensure safety and naturalness, compliant motion is already implemented in large-size robots, but it is still an undeveloped area in child-oriented robots as it calls for a lightweight and compact solution compared with large-size robots. In this paper, we proposed the design of a social robot which aims at conducting safe and playful human-Robot interaction (HRI), especially with children. We built a teddy bear robot prototype based on hybrid passive-active compliant system which consists of flexible joints as passive part and compliant motion controller as active part. The compliant controller detects external perturbation through motor state variables, therefore force and torque sensors could be omitted to keep overall system compact. Experiments conducted in typical HRI scenarios showed that the hybrid passive-active compliant system enabled our robot to conduct safer and more interactive physical interaction compared with robot under traditional control method.

This symposium addresses how different classes of research methods, all based upon the use of log data from educational software, can facilitate the analysis of students' learning strategies and behaviors. To this end, four multi-method programs of research are discussed, including the use of qualitative, quantitative-statistical, quantitative-modeling, and educational data mining methods. The symposium presents evidence regarding the applicability of each type of method to research questions of different grain sizes, and provides several examples of how these methods can be used in concert to facilitate our understanding of learning processes, learning strategies, and behaviors related to motivation, meta-cognition, and engagement. © ISLS.

27th International Conference Extended Abstracts on human Factors in Computing Systems, CHI 2009

This paper describes a research effort to support collaborative translation by monolingual speakers, or people that speak only the source or target language. I hypothesize that sharing knowledge across the language barrier is possible with a combination of automated (but poor quality) machine translation, language-independent communication, and existing background knowledge. I demonstrate this possibility with proof-of-concept experiments.

This paper evaluates the input performance capabilities of Velocity Threshold (I-VT) and Kalman Filter (I-KF) eye movement detection models when employed for eye-gaze-guided interface control. I-VT is a common eye movement identification model employed by the eye tracking community, but it is neither robust nor capable of handling high levels of noise present in the eye position data. Previous research implies that use of a Kalman filter reduces the noise in the eye movement signal and predicts the signal during brief eye movement failures, but the actual performance of I-KF was never evaluated. We evaluated the performance of I-VT and I-KF models using guidelines for ISO 9241 Part 9 standard, which is designed for evaluation of non keyboard/mouse input devices with emphasis on performance, comfort, and effort. Two applications were implemented for the experiment: 1) an accuracy test 2) a photo viewing application specifically designed for eye-gaze-guided control. Twenty-one subjects participated in the evaluation of both models completing a series of tasks. The results indicates that I-KF allowed participants to complete more tasks with shorter completion time while providing higher general comfort, accuracy and operation speeds with easier target selection than the I-VT model. We feel that these results are especially important to the engineers of new assistive technologies and interfaces that employ eye-tracking technology in their design. Copyright 2009 ACM.

An increasing number of temporal categorical databases are being collected: Electronic Health Records in healthcare organizations, traffic incident logs in transportation systems, or student records in universities. Finding similar records within these large databases requires effective similarity measures that capture the searcher's intent. Many similarity measures exist for numerical time series, but temporal categorical records are different. We propose a temporal categorical similarity measure, the M&M (Match & Mismatch) measure, which is based on the concept of aligning records by sentinel events, then matching events between the target and the compared records. The M&M measure combines the time differences between pairs of events and the number of mismatches. To accommodate customization of parameters in the M&M measure and results interpretation, we implemented Similan, an interactive search and visualization tool for temporal categorical records. A usability study with 8 participants demonstrated that Similan was easy to learn and enabled them to find similar records, but users had difficulty understanding the M&M measure. The usability study feedback, led to an improved version with a continuous timeline, which was tested in a pilot study with 5 participants. ©2009 IEEE.

The benefits of pet ownership to physical and mental health are extensive and well documented. Online social networks have the potential to strengthen these relationships and build community among pet owners. In this work, we present several results on the difference in behavior between dog and cat owners in pet-oriented social networks. We extend this analysis to divisions between urban and rural users. Our results show that there are significant differences among these groups. We propose a theory for future testing that more socially isolated the owners are from real-world communities of similar pet owners, the more active they are in forming social connections on these websites, and we offer initial evidence to support this. These results show that these pet social networks are already being used to help support the human-animal bond online, and that different types of pet owners would benefit from different types of support within the systems.
