Gesture keyboards represent an increasingly popular way to input text on mobile devices today. However, current gesture keyboards are exclusively unimanual. To take advantage of the capability of modern multi-touch screens, we created a novel bimanual gesture text entry system, extending the gesture keyboard paradigm from one finger to multiple fingers. To address the complexity of recognizing bimanual gesture, we designed and implemented two related interaction methods, finger-release and space-required, both based on a new multi-stroke gesture recognition algorithm. A formal experiment showed that bimanual gesture behaviors were easy to learn. They improved comfort and reduced the physical demand relative to unimanual gestures on tablets. The results indicated that these new gesture keyboards were valuable complements to unimanual gesture and regular typing keyboards.

Zhang, Ying, Bern, Marshall, Liu, Juan, Partridge, Kurt, Begole, Bo, Moore, Bob, Reich, Jim and Kishimoto, Koji (2010): Facilitating meetings with playful feedback. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 4033-4038.
Effective group meetings are important for the productivity of corporations. Various types of meeting facilitators have been developed over the past couple of years. We present a prototype that is unique because it captures both individual and group behaviors and provides real time playful feedback. The portable prototype includes a set of table-top microphones with an audio interface to a laptop PC, where audio data are processed and an avatar-based UI displays the shared state of individual and group behaviors during a meeting. The interface reveals not only level of participation, but also several other meaningful but harder to detect behaviors such as turn taking, interruptions, and group laughter. The presentation's design is deliberately playful to keep participants monitor, self-estimate and improve their meeting behavior.

Experiments with a Mixed-Model Recommender for Leisure Activities. In: Proceedings of the 2009 Conference on User Modeling, Adaptation and Personalization 2009. pp. 295-306.
Collaborative filtering (CF) is at the heart of most successful recommender systems nowadays. While this technique often provides useful recommendations, conventional systems also ignore data that could potentially be used to refine and adjust recommendations based on a user's context and preferences. The problem is particularly acute with mobile systems where information delivery often needs to be contextualized. Past research has also shown that combining CF with other techniques often improves the quality of recommendations. In this paper, we present results from an experiment assessing user satisfaction with recommendations for leisure activities that are obtained from different combinations of these techniques. We show that the most effective mix is highly dependent on a user's familiarity with a geographical area and discuss the implications of our findings for future research.

Partridge, Kurt and Price, Bob (2009): Enhancing Mobile Recommender Systems with Activity Inference. In: Proceedings of the 2009 Conference on User Modeling, Adaptation and Personalization 2009. pp. 307-318.
Today's mobile leisure guide systems give their users unprecedented help in finding places of interest. However, the process still requires significant user interaction, for example to specify preferences and navigate lists. While interaction is effective for obtaining desired results, learning the interaction pattern can be an obstacle for new users, and performing it can slow down experienced users. This paper describes how to infer a user's high-level activity automatically to improve recommendations. Activity is determined by interpreting a combination of current sensor data, models generated from historical sensor data, and priors from a large time-use study. We present an initial user study that shows an increase in prediction accuracy

Yatani, Koji, Partridge, Kurt, Bern, Marshall and Newman, Mark W. (2008): Escape: a target selection technique using visually-cued gestures. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 285-294.
Many mobile devices have touch-sensitive screens that people interact with using fingers or thumbs. However, such interaction is difficult because targets become occluded, and because fingers and thumbs have low input resolution. Recent research has addressed occlusion through visual techniques. However, the poor resolution of finger and thumb selection still limits selection speed. In this paper, we address the selection speed problem through a new target selection technique called Escape. In Escape, targets are selected by gestures cued by icon position and appearance. A user study shows that for targets six to twelve pixels wide, Escape performs at a similar error rate and at least 30% faster than Shift, an alternative technique, on a similar task. We evaluate Escape's performance in different circumstances, including different icon sizes, icon overlap, use of color, and gesture direction. We also describe an algorithm that assigns icons to targets, thereby improving Escape's performance.

In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 1157-1166.
This paper presents a context-aware mobile recommender system, codenamed Magitti. Magitti is unique in that it infers user activity from context and patterns of user behavior and, without its user having to issue a query, automatically generates recommendations for content matching. Extensive field studies of leisure time practices in an urban setting (Tokyo) motivated the idea, shaped the details of its design and provided data describing typical behavior patterns. The paper describes the fieldwork, user interface, system components and functionality, and an evaluation of the Magitti prototype.

TiltType is a novel text entry technique for mobile devices. To enter a
character, the user tilts the device and presses one or more buttons. The
character chosen depends on the button pressed, the direction of tilt, and the
angle of tilt. TiltType consumes minimal power and requires little board space,
making it appropriate for wristwatch-sized devices. But because controlled
tilting of one's forearm is fatiguing, a wristwatch using this technique must
be easily removable from its wriststrap. Applications include two-way paging,
text entry for watch computers, web browsing, numeric entry for calculator
watches, and existing applications for PDAs.

In: Marks, Joe and Mynatt, Elizabeth D. (eds.) Proceedings of the 14th annual ACM symposium on User interface software and technology November 11 - 14, 2001, Orlando, Florida. pp. 183-190.
Intrabody communication (IBC) is a wireless communications technology that
uses a person's body as the transmission medium for imperceptible electrical
signals. Because communication is limited to the vicinity of a person's body,
ambiguities arising from communication between personal devices and
environmental devices when multiple people are present can, in theory, be
solved simply. Intrabody communication also potentially allows data to be
transferred when a person touches an IBC-enabled device. We have designed and
constructed an intrabody communication system, modeled after Zimmerman's
original design, and extended it to operate up to 38.4Kbps and to calculate
signal strength. In this paper, we present quantitative measurements of data
error rates and signal strength while varying hand distance to transceiver
plate, electrode location on the body, touch plate size and shape, and several
other factors. We find that plate size and shape have only minor effects, but
that the distance to plate and the coupling mechanism significantly effect
signal strength. We also find that portable devices, with poor ground coupling,
suffer more significant signal attenuation. Our goal is to promote design
guidelines for this technology and identify the best contexts for its effective
