Understanding user engagement in immersive and interactive stories
(Georgia Institute of Technology, 2008-09-23)Popular science fiction often proffers the Holodeck vision for future immersive media: a seamless and transparent interface connecting users to a virtual world where they transform into a story character and influence ... -
Understanding visual analysis processes from user interactions using visual analytics
(Georgia Institute of Technology, 2016-11-15)Understanding the visual analysis process taken by people when using a visualization application can help its designers improve the application. This goal is typically achieved by observing usage sessions. Unfortunately, ... -
A unified approach to analogical reasoning
(Georgia Institute of Technology, 1990) -
Universal graph literacy: understanding how blind and low vision students can satisfy the common core standards with accessible auditory graphs
(Georgia Institute of Technology, 2013-04-08)Auditory graphs and active point estimation provide an inexpensive, accessible alternative for low vision and blind K-12 students using number lines and coordinate graphs. In the first phase of this research program, a ... -
Universal multihead automata

Unlocking the urban photographic record through 4D scene modeling
(Georgia Institute of Technology, 2010-07-09)Vast collections of historical photographs are being digitally archived and placed online, providing an objective record of the last two centuries that remains largely untapped. We propose that time-varying 3D models can ... -
Unsupervised Activity Discovery and Characterization for Sensor-Rich Environments
(Georgia Institute of Technology, 2005-11-28)This thesis presents an unsupervised method for discovering and analyzing the different kinds of activities in an active environment. Drawing from natural language processing, a novel representation of activities as bags ... -
Unsupervised discovery of activity primitives from multivariate sensor data
(Georgia Institute of Technology, 2008-07-08)This research addresses the problem of temporal pattern discovery in real-valued, multivariate sensor data. Several algorithms were developed, and subsequent evaluation demonstrates that they can efficiently and accurately ... -
Unsupervised learning of disease subtypes from continuous time Hidden Markov Models of disease progression
(Georgia Institute of Technology, 2015-08-21)The detection of subtypes of complex diseases has important implications for diagnosis and treatment. Numerous prior studies have used data-driven approaches to identify clusters of similar patients, but it is not yet clear ... -
Urban 3D scene understanding from images
(Georgia Institute of Technology, 2018-01-22)Human vision is marvelous in obtaining a structured representation of complex dynamic scenes, such as spatial scene-layout, re-organization of the scene into its constituent objects, support of each object, etc. We also ... -
User interface reengineering

User-level state sharing in distributed systems
(Georgia Institute of Technology, 1996-05) -
User’s role in shaping WeChat as an infrastructure: practice, appropriation, creation
(Georgia Institute of Technology, 2020-08-17)The past decade has seen the rapid development of information and communication technologies, particularly online social platforms such as Twitter and Facebook. While online social platforms have existed since the early ... -
Using Availability Indicators to Enhance Context-Aware Family Communication Applications
(Georgia Institute of Technology, 2006-07-05)Family conversation between homes is difficult to initiate at mutually agreeable times as neither participant has exact knowledge of the other's activities or intentions. Whether calling to plan an important family gathering ... -
Using Graphical Context to Reduce the Effects of Registration Error in Augmented Reality
(Georgia Institute of Technology, 2007-11-09)An ongoing research focus in Augmented Reality (AR) is to improve tracking and display technology in order to minimize registration errors between the graphical display and the physical world. However, registration is not ... -
Using Intel® SGX technologies to secure large scale systems in public cloud environments
(Georgia Institute of Technology, 2018-01-09)Intel SGX enables securing applications at the hardware level, which makes it a very useful tool for running applications on untrusted hosts. Security based on hardware mechanisms is a rapidly evolving research area. SGX ... -
Using observations to recognize the behavior of interacting multi-agent systems
(Georgia Institute of Technology, 2008-05-19)Behavioral research involves the study of the behaviors of one or more agents (often animals) in order to better understand the agents' thoughts and actions. Identifying subject movements and behaviors based upon those ... -
Using Student-Generated Notes as an Interface to a Digital Repository
(Georgia Institute of Technology, 2005-11-28)A recent survey of studies related to digital libraries concluded that students use and like electronic resources. However, the results of access studies show that actual use of online content is relatively low, with only ... -
Using ubiquitous communication technology to improve pediatric asthma management
