Cueing multimedia search with audiovisual blur
Tifanie Bouchara, Christian Jacquemin, Brian F. G. Katz
Article No.: 7
DOI: 10.1145/2465780.2465781

Situated in the context of multimedia browsing, this study concerns perceptual processes involved in searching for an audiovisual object displayed among several distractors. The aim of the study is to increase the perceptual saliency of the target...

Measuring the degree of face familiarity based on extended NMF
Ce Zhan, Wanqing Li, Philip Ogunbona
Article No.: 8
DOI: 10.1145/2465780.2465782

Getting familiar with a face is an important cognitive process in human perception of faces, but little study has been reported on how to objectively measure the degree of familiarity. In this article, a method is proposed to quantitatively...

Analyzing correspondence between sound objects and body motion
Kristian Nymoen, Rolf Inge Godøy, Alexander Refsum Jensenius, Jim Torresen
Article No.: 9
DOI: 10.1145/2465780.2465783

Links between music and body motion can be studied through experiments called sound-tracing. One of the main challenges in such research is to develop robust analysis techniques that are able to deal with the multidimensional data that...

Graph-based joint clustering of fixations and visual entities
Yusuke Sugano, Yasuyuki Matsushita, Yoichi Sato
Article No.: 10
DOI: 10.1145/2465780.2465784

We present a method that extracts groups of fixations and image regions for the purpose of gaze analysis and image understanding. Since the attentional relationship between visual entities conveys rich information, automatically determining the...

Learning to walk in virtual reality
Roy A. Ruddle, Ekaterina Volkova, Heinrich H. Bülthoff
Article No.: 11
DOI: 10.1145/2465780.2465785

This article provides longitudinal data for when participants learned to travel with a walking metaphor through virtual reality (VR) worlds, using interfaces that ranged from joystick-only, to linear and omnidirectional treadmills, and actual...
