Motivated by and grounded in observations of foot patterns in a human-human dialogue, this study explores expressions of spatial interest through feet at public displays. We conducted an observation and recorded user foot orientation and position in a public information display environment leading to data about 84 interaction sessions. Our observations show that characteristic foot patterns can be matched with two user intentions: (A) Users who seek access to specific information, and (B) users who don't seek specific information. With the goal to detect intention through foot patterns, we classified characteristic foot patterns with a SVM pattern recognition algorithm, which resulted in a detection accuracy of 84.4%. This work can be valuable for researchers designing context-aware public displays.

In this paper, we present the design of Hero, a suite of learning tools that combine teacher-created extracurricular challenges with in-class motivational tools to help parents become more involved in their child's education, while also engaging students in their own learning. To inform the design, we conducted field studies and interviews involving 7 primary teachers and 15 different families. We analyzed Chinese parenting styles and problems related to parental involvement, and developed three major themes from the data. We then proposed three design goals and created a high-fidelity prototype after several iterations of user testing. A preliminary evaluation showed that teachers, parents, and students could all benefit from the design.

Personal informatics systems that help people both collect and reflect on various kinds of personal information are growing rapidly. Despite the importance of journaling and the main role it has in tracking one's personal growth, a limited number of studies have examined journaling in the area of personal informatics in detail. In this paper, we critically examine the process of reflection on experiences, thoughts and evolving insights through a qualitative research study. We also present the design research process we conducted to develop the Wandering Mind as a support tool to help individuals record and reflect on their experiences.

Effective communication between patients and their clinicians during clinical encounters has a positive impact on health outcomes. Technology has the potential to help transform this synchronous interaction, but re-searchers are still at early stages of developing interventions to assess and improve patient-clinician communication. In this workshop, we envision opening up a dialogue among researchers and clinicians who wish to discuss directions for future research in this domain. In particular, the workshop will focus on exploring how technologies available today, as well as projected for the future, can support the communication needs of clinicians and patients.

Graphical password schemes can provide better usability than text passwords, especially on smartphones where typing complex passwords on a virtual keyboard can be tedious. However, in order to achieve password strength comparable to text passwords, graphical password schemes require multiple rounds and, therefore, have longer entry times. We propose MIBA as an image-based authentication method that leverages multitouch in order to increase the password space by supporting multiple fingers for click point selection. We outline the MIBA concept, report on practical constraints for multitouch click point selection, and discuss preliminary results that indicate short entry times and the usability of MIBA.

We present initial work towards recognizing reading activities. This paper describes our efforts detect the English skill level of a user and infer which words are difficult for them to understand. We present an initial study of 5 students and show our findings regarding the skill level assessment. We explain a method to spot difficult words. Eye tracking is a promising technology to examine and assess a user's skill level.

In recent years there has been a widespread installation of large interactive public displays. Longitudinal studies however show that these interactive displays suffer from interaction blindness - the inability of the public to recognize the interactive capabilities of those surfaces. In this paper, we explore the use of curiosity-provoking artifacts, (curiosity objects) to overcome interaction blindness. Our study confirmed the interaction blindness problem and shows that introducing a curiosity object results in a significant increase in interactivity with the display as well as changes in movement in the spaces surrounding the interactive display.

Non-light-emissive textile displays have become a popular research area that allows subtle and ambient animations on our textiles. This work explores one such existing technology which uses thermochromic inks and peltier semiconductors to implement touch sensitive non-light-emissive textile display. To achieve this we investigate a new method that detects temperature transients (caused by a touch) in order to detect a touch which allows interactive touch sensitive textile displays without any changes to the existing hardware.
