Virginia Tech was one of five institutions nationwide to receive the Microsoft HoloLens Academic Research Grant Award, including $100,000 and two Hololens Development Edition devices. The winning submission, titled "Collaborative Analysis of Large-scale Mixed Reality Data" was awarded to PI Joseph Gabbard (an Associate Professor of Human Factors, ISE @ VT) and Co-PI Doug Bowman (Professor of CS), with support from several faculty in the Center for Human-Computer Interaction's 3DExperiences group.
Housed within the Institute for Creativity, Arts and Technology, the Center for HCI's 3DExperiences Group is one of the largest interdisciplinary AR/VR groups in the world, consisting of faculty from computer science, human factors, psychology, visual arts, communications, geography, engineering and education.
The funded research will investigate multi-user visualization of, and interaction with, big datasets in collaborative mixed reality environments. The research is inspired by large physical spaces (e.g., museums) that allow users to stand around large objects in expansive spaces, each with individual points of view, but with common ground and the ability to understand what others are looking at and talking about. Using the ICAT Cube, the researchers will develop tools allowing users wearing HoloLens devices to explore and analyze large-scale meteorological datasets, representative of big data, to examine core user interaction issues in multi-user collaborative settings.
Check out the official announcement from Microsoft here.
In response to the news, PI Gabbard noted that, "We are honored to have received this award and level of recognition. Indeed, given the highly competitive field, this award suggests to me that Microsoft acknowledges Virginia Tech's world-class faculty, research and facilities in the areas of Augmented and Mixed Reality. We've worked hard to establish ourselves in this area, and are excited to partner with Microsoft to further our collective knowledge."

Ben Hanrahan successfully defended his dissertation, which investigated the effects of email features on users lives, particularly how users attend to email and get lost within it. The balance between promptly responding to emails while trying to limit engagement with the technology, were among his most important findings about the social problems of our interactions with email.

Email has become deeply embedded in many users' daily lives. To investigate how email features in users lives, particularly how users attend to email and get lost within it, I ran a series of studies that probed how users determine relevancy of messages, logged interactions with email, gathered diary entries related to individual sessions, and investigated the gratifications sought from email use. In my studies I found that the majority of attentional effort is around reading email and participating in conversations, as opposed to email management. I also found that participants attended to email primarily based on notifications, instead of the number of unread messages in their inbox. I present my results through answering several research questions, and leverage Conversational Analysis (CA), particularly conversational openings, to explicate several problematic aspects around email use. My findings point to inefficiencies in email as a communication medium, mainly, around how summons are (or are not) issued. This results in an increased burden on email users to maintain engagement and determine (or construct) the appropriate moment for interruption.
My findings have several implications: email triage does not seem to be problematic for the participants of my studies, somewhat in contrast to previous research; much of the problem around email, particularly getting lost in email is in managing the tension between promptly responding to messages while limiting engagement with email; due to the social nature of the problems with email, modifications to the email client are limited in their potential effectiveness to prevent getting lost and reduce email related anxiety.

The paper titled "Towards Crowd-based Customer Service: A Mixed-Initiative Tool for Managing Q&A Sites" with co-authors Tiziano Piccardi (Xerox Research Center Europe), Gregorio Convertino (Informatica Corporation, US), Massimo Zancanaro (FBK, Italy), Cedric Archambeau (Amazon Inc., Germany) was the result of an interdisciplinary project Ji Wang participated at during his internship at Xerox Research in France, last Summer.
Abstract: In this paper, we propose a mixed-initiative approach to integrate a Q&A site based on a crowd of volunteers with a standard operator-based help desk, ensuring quality of customer service. Q&A sites have emerged as an efficient way to address questions in various domains by leveraging crowd knowledge. However, they lack sufficient reliability to be the sole basis of customer service applications. We built a proof-of-concept mixed-initiative tool that helps a crowd-manager to decide if a question will get a satisfactory and timely answer by the crowd or if it should be redirected to a dedicated operator. A user experiment found that our tool reduced the participants' cognitive load and improved their performance, in terms of their precision and recall. In particular, those with higher performance benefited more than those with lower performance.
