Tullio, Joe, Huang, Elaine, Wheatley, David, Zhang, Harry, Guerrero, Claudia and Tamdoo, Amruta (2010): Experience, adjustment, and engagement: the role of video in law enforcement. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 1505-1514.
Questions about the effectiveness of increasingly ubiquitous video technology in law enforcement have prompted an examination of the practices surrounding this technology. We present the results of a multi-site study aimed at understanding the use of video in several phases of law enforcement, from crime prevention and response to investigation and prosecution. Our findings show that while video has provided numerous benefits to law enforcement agencies, in many cases the technology either fails to support key facets of work or introduces new tasks that present an additional burden to workers. We discuss the need to incorporate human experience and tacit knowledge, operator engagement, and the greater ecosystem of work into video deployments.

Huang, Elaine M., Harboe, Gunnar, Tullio, Joe, Novak, Ashley, Massey, Noel, Metcalf, Crysta J. and Romano, Guy (2009): Of social television comes home: a field study of communication choices and practices in tv-based text and voice chat. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 585-594.
Social television applications have emerged as a potentially valuable convergence of media and communication, but questions remain about the utility and nature of the communication experiences they will provide. We present our study of STV3, an application that adds freeform text and voice chat capabilities to the conventional television-viewing experience. We conducted an in-depth field study of STV3 to understand how friends integrate communication through social television into their lives. Our results reveal users' choices of communication modality, their topics of conversation, and the sense of connectedness that was fostered through their use of STV3. Our findings indicate that participants overwhelmingly preferred text chat to voice chat, and that they often communicated about topics unrelated to the television content.

Harboe, Gunnar, Metcalf, Crysta J., Bentley, Frank, Tullio, Joe, Massey, Noel and Romano, Guy (2008): Ambient social tv: drawing people into a shared experience. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 1-10.
We examine how ambient displays can augment social television. Social TV 2 is an interactive television solution that incorporates two ambient displays to convey to participants an aggregate view of their friends' current TV-watching status. Social TV 2 also allows users to see which television shows friends and family are watching and send lightweight messages from within the TV-viewing experience. Through a two-week field study we found the ambient displays to be an integral part of the experience. We present the results of our field study with a discussion of the implications for future social systems in the home.

In order to develop intelligent systems that attain the trust of their users, it is important to understand how users perceive such systems and develop those perceptions over time. We present an investigation into how users come to understand an intelligent system as they use it in their daily work. During a six-week field study, we interviewed eight office workers regarding the operation of a system that predicted their managers' interruptibility, comparing their mental models to the actual system model. Our results show that by the end of the study, participants were able to discount some of their initial misconceptions about what information the system used for reasoning about interruptibility. However, the overarching structures of their mental models stayed relatively stable over the course of the study. Lastly, we found that participants were able to give lay descriptions attributing simple machine learning concepts to the system despite their lack of technical knowledge. Our findings suggest an appropriate level of feedback for user interfaces of intelligent systems, provide a baseline level of complexity for user understanding, and highlight the challenges of making users aware of sensed inputs for such systems.

In this paper, we describe Augur, a groupware calendar system to support
personal calendaring practices, informal workplace communication, and the
socio-technical evolution of the calendar system within a workgroup. Successful
design and deployment of groupware calendar systems have been shown to depend
on several converging, interacting perspectives. We describe calendar-based
work practices as viewed from these perspectives, and present the Augur system
in support of them. Augur allows users to retain the flexibility of personal
calendars by anticipating and compensating for inaccurate calendar entries and
idiosyncratic event names. We employ predictive user models of event
attendance, intelligent processing of calendar text, and discovery of shared
events to drive novel calendar visualizations that facilitate interpersonal
communication. In addition, we visualize calendar access to support privacy
management and long-term evolution of the calendar system.

(2001): Support for multitasking and background awareness using interactive peripheral displays. 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. 41-50.
In this paper, we describe Kimura, an augmented office environment to
support common multitasking practices. Previous systems, such as Rooms, limit
users by constraining the interaction to the desktop monitor. In Kimura, we
leverage interactive projected peripheral displays to support the perusal,
manipulation and awareness of background activities. Furthermore, each activity
is represented by a montage comprised of images from current and past
interaction on the desktop. These montages help remind the user of past
actions, and serve as a springboard for ambient context-aware reminders and

Mynatt, Elizabeth D. and Tullio, Joe (2001): Inferring Calendar Event Attendance. In: International Conference on Intelligent User Interfaces 2001 January 14-17, 2001, Sanata Fe, New Mexico, USA. pp. 121-128.
The digital personal calendar has long been established as an effective tool for supporting workgroup coordination. For the new class of ubiquitous computing applications, however, the calendar can also be seen as a sensor, providing both location and availability information to these applications. In most cases, however, the calendar represents a sequence of events that people could (or should) attend, not their actual daily activities. To assist in the accurate determination of user whereabouts and availability, we present Ambush, a calendar system extension that uses a Bayesian model to predict the likelihood of one's attendance at the events listed on his or her schedule. We also present several techniques for the visual display of these likelihoods in a manner intended to be quickly interpreted by users examining the calendar.

Hinckley, Ken, Tullio, Joe, Pausch, Randy, Proffitt, Dennis and Kassell, Neal F. (1997): Usability Analysis of 3D Rotation Techniques. In: Robertson, George G. and Schmandt, Chris (eds.) Proceedings of the 10th annual ACM symposium on User interface software and technology October 14 - 17, 1997, Banff, Alberta, Canada. pp. 1-10.
We report results from a formal user study of interactive 3D rotation using the mouse-driven Virtual Sphere and Arcball techniques, as well as multidimensional input techniques based on magnetic orientation sensors. Multidimensional input is often assumed to allow users to work quickly, but at the cost of precision, due to the instability of the hand moving in the open air. We show that, at least for the orientation matching task used in this experiment, users can take advantage of the integrated degrees of freedom provided by multidimensional input without necessarily sacrificing precision: using multidimensional input, users completed the experimental task up to 36% faster without any statistically detectable loss of accuracy. We also report detailed observations of common usability problems when first encountering the techniques. Our observations suggest some design issues for 3D input devices. For example, the physical form-factors of the 3D input device significantly influenced user acceptance of otherwise identical input sensors. The device should afford some tactile cues, so the user can feel its orientation without looking at it. In the absence of such cues, some test users were unsure of how to use the device.
