HCI graduate students sponsor and contribute to a seminar program in the Center for Human Computer Interaction. This is both a professional and a social event. Come and meet your fellow HCI students. Graduate students can take advantage of this venue to practice a talk in advance of a conference or to present ongoing research, and receive feedback from the CHCI community. This is also a good opportunity for new students interested in doing research in HCI to get to learn more about HCI, and learn about the research being done by each research group in the center. Refreshments are provided!
For more information, please see the seminar schedule.
When: 12:30pm on 2nd and 4th Fridays of the month. Seminars by visitors might be at other days/times.
Where: GLC Room B.
If you would like to present, please contact Dr. Andrea Kavanaugh (firstname.lastname@example.org).
Presenter: Panagiotis Apostolellis
Abstract: Free-choice or informal learning has gained considerable ground in education during the last years, either through online platforms, serious games, or interactive museums. Informal learning spaces provide ample opportunities for students to learn contextually, socially, and in an entertaining manner as long as available technologies are integrated. Additionally, virtual reality environments in the form of 3d games have become so widely available that most teenagers are nowadays avid games and can interact proficiently with such systems. Thus, we have conducted an empirical study with middle school students in groups of three watching or playing a computer 3d game about olive oil production on a large display. Students had to either watch someone play the game or they had to play together using Xbox controllers to navigate an olive oil factory and produce olive oil by operating collaboratively all the machinery involved in the process. Preliminary findings have not confirmed our hypothesis that group collaboration with increased game control will afford greater learning compared to the passive condition, which is the norm in groups of students visiting such technology-enhanced spaces. We will also discuss our findings about measures of game experience (immersion, challenge, affect, etc.) and social presence and how we expect them to affect the results, once all data have been gathered.
Bio: Panagiotis Apostolellis is a PhD candidate of Computer Science at VT working under the guidance of Dr. Doug Bowman at the Center for Human Computer Interaction. His working experience in an interactive museum for more than a decade intrigued his interest to explore how the combination of various commodity technologies can be exploited for the benefit of informal learning, specifically for groups of school-age students. Before joining his former occupation at the Foundation of the Hellenic World in Athens (Greece) and Virginia Tech, he completed a BSc in Electrical Engineering (Patras, Greece) and a MSc in Human-Centered Computer Systems at Sussex University (UK).
Presenter: Prof. Steven Sheetz
Abstract: We apply Interpersonal Deception Theory (IDT), augmented by auditor affect, to predict auditors' perceptions of deception in client communications. Ninety participants assessed their perceptions of the client, the interaction, their own affect regarding the client, and their perceptions of deception within two audit simulation tasks. Results suggest unfavorable perceptions of the interaction with the client increase perceptions of deception and lower auditor affect. Components of client disposition, e.g., sociability, do not directly influence perceptions of deception, although sociability does influence auditor affect. Lower affect contributes to higher perceptions of deception, suggesting that negative affect improves the auditor's ability to detect deception. Using structural equation modeling to test IDT constructs in a nomological network with auditor affect extends literature on deception detection in accounting and psychology. Our results suggest that an awareness of situational factors, including one's own affective state, may be leveraged to improve deception detection. Additionally, results imply that the role of affect in decision-making is dependent upon situational context.

Presenter: Prof. Sile O\'Modhrain
Abstract: As Al Bregman has so eloquently noted, the auditory system routinely accomplishes a phenomenal feat, that of parsing the motion of waves in a 3-dimensional soup of gas to uniquely identify individual auditory objects located anywhere in the space around us. Using discrepancies in time that range from less than a millisecond for phase shifts at high frequencies to numbers of seconds for reverberation times of large rooms, we are able to organise the motion of air around us into the temporal, spectral and spatial attributes of sounding objects and their reflections. From this, we can identify such properties as the size of a room, the voice of a friend or the number of violins playing in an orchestra. In this talk, I will propose that the mechanisms that underlie our ability to perform Auditory Scene Analysis such as fusion and stream segregation can be drawn upon to reveal patterns and relationships within large, complex, dynamic data sets. To illustrate this, I will discuss the work of a Ph.D. student currently collaborating with scientists at NASA Goddard that is revealing hitherto undiscovered relationships between frequency components in data from solar wind.
Bio: Sile O'Modhrain is a professor in Performing Arts Technology at the school of Music, Theatre and Dance at the University of Michigan. Her research focuses on human-computer interaction, especially interfaces incorporating haptic and auditory feedback. She earned her master's degree in music technology from the University of York and her PhD from Stanford University's Center for Computer Research in Music and Acoustics (CCRMA). She has also worked as a sound engineer and producer for BBC Network Radio. In 1994, she received a Fulbright scholarship, and went to Stanford to develop a prototype haptic interface augmenting graphical user interfaces for blind computer users. Before taking up her position at the University of Michigan, Sile taught at the Sonic Arts Research Centre at Queens University Belfast and, from 2001-2005 directed the Palpable Machines group at Media Lab Europe. Here her work focused on new interfaces for hand-held devices that tightly couple gestural input and touch or haptic display.
Presenter: Prof. Craig Woolsey
Abstract: The Virginia Center for Autonomous Systems (www.unmanned.vt.edu) is an ICTAS/College of Engineering research center which facilitates interdisciplinary research in autonomous systems. VaCAS hosts research activities spanning every application domain (water, land, air, and space). Member research activities range from fundamental control theory to vehicle development to applications for science, security, and commerce. In this presentation, Dr. Woolsey will review a selection of research activities within VaCAS. Examples include motion planning and control strategies for underwater gliders, mapping and navigation methods for unmanned surface vessels in river environments, an unmanned ground vehicle that supports light infantry, an autonomous aircraft that can perform precise, aggressive maneuvers, and a concept for exploring Europa's ice-covered liquid ocean. One of the speaker's objectives is to encourage an open discussion of the human/computer interaction challenges related to autonomous systems.

He is also the founding Director of the Virginia Center for Autonomous Systems. The principal aim of Dr. Woolsey's research is to improve performance and robustness of autonomous vehicles, particularly ocean and atmospheric vehicles. The theoretical focus is nonlinear control, particularly energy-based methods for mechanical control systems. Dr. Woolsey is a past recipient of the NSF Career Award and the ONR Young Investigator Program Award, as well as the SAE Ralph R. Teetor Educational Award.
Presenter: Michael Stewart
Abstract: Many Computer-Supported Cooperative Work (CSCW) applications go to great lengths to maximize transparency by making available participants' actions and respective application states to all others in real-time. Designers might intend to enhance coordination through increased transparency, but what other outcomes might be influenced by these choices? How might the minute details of how we carry out our daily moment-to-moment coordinative activities be affected?
