Exploring the Benefits of Context in 3D Gesture Recognition for Game-Based Virtual Environments
Eugene M. Taranta II, Thaddeus K. Simons, Rahul Sukthankar, Joseph J. Laviola Jr.
Article No.: 1
DOI: 10.1145/2656345

We present a systematic exploration of how to utilize video game context (e.g., player and environmental state) to modify and augment existing 3D gesture recognizers to improve accuracy for large gesture sets. Specifically, our work develops and...

Human Tutorial Instruction in the Raw
Yolanda Gil
Article No.: 2
DOI: 10.1145/2531920

Humans learn procedures from one another through a variety of methods, such as observing someone do the task, practicing by themselves, reading manuals or textbooks, or getting instruction from a teacher. Some of these methods generate examples...

Gaze and Attention Management for Embodied Conversational Agents
Tomislav Pejsa, Sean Andrist, Michael Gleicher, Bilge Mutlu
Article No.: 3
DOI: 10.1145/2724731

To facilitate natural interactions between humans and embodied conversational agents (ECAs), we need to endow the latter with the same nonverbal cues that humans use to communicate. Gaze cues in particular are integral in mechanisms for...

Emotional States Associated with Music: Classification, Prediction of Changes, and Consideration in Recommendation
James J. Deng, Clement H. C. Leung, Alfredo Milani, Li Chen
Article No.: 4
DOI: 10.1145/2723575

We present several interrelated technical and empirical contributions to the problem of emotion-based music recommendation and show how they can be applied in a possible usage scenario. The contributions are (1) a new three-dimensional...

A Wearable Assistant for Gait Training for Parkinson’s Disease with Freezing of Gait in Out-of-the-Lab Environments
Sinziana Mazilu, Ulf Blanke, Moran Dorfman, Eran Gazit, Anat Mirelman, Jeffrey M. Hausdorff, Gerhard Tröster
Article No.: 5
DOI: 10.1145/2701431

People with Parkinson’s disease (PD) suffer from declining mobility capabilities, which cause a prevalent risk of falling. Commonly, short periods of motor blocks occur during walking, known as freezing of gait (FoG). To slow the progressive...
