Audience response is an important indicator of the quality of performing arts. Psychophysiological measurements enable researchers to perceive and understand audience response by collecting their bio-signals during a live performance. However, how the audience respond and how the performance is affected by these responses are the key elements but are ...
Keywords: Audience engagement, adaptive user interface, brain-computer interface (BCI), digital performance

Audience engagement is an important indicator of the quality of the performing arts but hard to measure. Psychophysiological measurements are promising research methods for perceiving and understanding audience's responses in real-time. Currently, such research are conducted by collecting biometric data from audience when they are watching a performance. In this ...

External self-image is often used as an effective tool to enhance dancing technique, choreography, creativity, and expression. The traditional tools of presenting external image, such as mirrors or videos, are limited in their mobility, perspective, and immediacy. To address the issue, we present OutsideMe, a vision-sync mixed reality system that ...
Keywords: mixed reality, choreography, external self-image, augmented human, visual blending

This paper addresses temporal synchronization of human actions under multiple view situation. Many researchers focused on frame by frame alignment for sync these multi-view videos, and expolited features such as interesting point trajectory or 3d human motion feature for event detecting individual. However, since background are complex and dynamic in ...

Automatic understanding of human activities is a huge challenge in multimedia analysis field. This challenge is especially critical in small-scale activities, such as finger motions, and activities in complex scenes. For typical camera views, both global feature and local feature analysis methods are unsuitable. To solve this problem, many studies ...

As video data generated by users boom continuously, making sense of large scale data archives is considered as a critical challenge for data management. Most existing learning techniques that extract signal-level contents from video data struggle to scale due to efficiency limits. With the development of pervasive positioning techniques, discovering ...

Many trackers have been proposed for tracking objects individually in previous research. However, it is still difficult to trust any single tracker over a variety of circumstances. Therefore, it is important to estimate how well each tracker performs and fusion the tracking results. In this paper, we propose a symbiotic ...
Keywords: information propagation, object tracking, multi-tracker, data association
