Space perception in virtual environments: Displacement from the center of projection causes less distortion than predicted by cue-based models
Jonathan W. Kelly, Melissa Burton, Brice Pollock, Eduardo Rubio, Michael Curtis, Julio De La Cruz, Stephen Gilbert, Eliot Winer
Article No.: 18
DOI: 10.1145/2536764.2536765

Virtual reality systems commonly include both monocular and binocular depth cues, which have the potential to provide viewers with a realistic impression of spatial properties of the virtual environment. However, when multiple viewers share the...

A framework for applying the principles of depth perception to information visualization
Zeynep Cipiloglu Yildiz, Abdullah Bulbul, Tolga Capin
Article No.: 19
DOI: 10.1145/2536764.2536766

During the visualization of 3D content, using the depth cues selectively to support the design goals and enabling a user to perceive the spatial relationships between the objects are important concerns. In this novel solution, we automate this...

Models of gaze control for manipulation tasks
Jose Nunez-Varela, Jeremy L. Wyatt
Article No.: 20
DOI: 10.1145/2536764.2536767

Human studies have shown that gaze shifts are mostly driven by the current task demands. In manipulation tasks, gaze leads action to the next manipulation target. One explanation is that fixations gather information about task relevant properties,...

Clustering approach to characterize haptic expressions of emotions
Yoren Gaffary, Victoria Eyharabide, Jean-Claude Martin, Mehdi Ammi
Article No.: 21
DOI: 10.1145/2536764.2536768

Several studies have investigated the relevance of haptics to physically convey various types of emotion. However, they use basic analysis approaches to identify the relevant features for an effective communication of emotion. This article...

Perceptual impact of gesture control of spatialization
G. Marentakis, S. Mcadams
Article No.: 22
DOI: 10.1145/2536764.2536769

In two experiments, visual cues from gesture control of spatialization were found to affect auditory movement perception depending on the identifiability of auditory motion trajectories, the congruency of audiovisual stimulation, the sensory focus...

Walking pace affected by interactive sounds simulating stepping on different terrains
Luca Turchet, Stefania Serafin, Paola Cesari
Article No.: 23
DOI: 10.1145/2536764.2536770

This article investigates whether auditory feedback affects natural locomotion patterns. Individuals were provided with footstep sounds simulating different surface materials. The sounds were interactively generated using shoes with pressure...

Intuitiveness of vibrotactile speed regulation cues
Jani Lylykangas, Veikko Surakka, Jussi Rantala, Roope Raisamo
Article No.: 24
DOI: 10.1145/2536764.2536771

Interpretations of vibrotactile stimulations were compared between two participant groups. In both groups, the task was to evaluate specifically designed tactile stimulations presented to the wrist or chest. Ascending, constant, and descending...

Virtual travel collisions: Response method influences perceived realism of virtual environments
Kristopher J. Blom, Steffi Beckhaus
Article No.: 25
DOI: 10.1145/2536764.2536772

Travel methods are the most basic and widespread interaction method with virtual environments. They are the primary and often the only way the user interactively experiences the environment. We present a study composed of three experiments that...

Saliency-maximized audio visualization and efficient audio-visual browsing for faster-than-real-time human acoustic event detection
Kai-Hsiang Lin, Xiaodan Zhuang, Camille Goudeseune, Sarah King, Mark Hasegawa-Johnson, Thomas S. Huang
Article No.: 26
DOI: 10.1145/2536764.2536773

Browsing large audio archives is challenging because of the limitations of human audition and attention. However, this task becomes easier with a suitable visualization of the audio signal, such as a spectrogram transformed to make unusual audio...

2D Linear oculomotor plant mathematical model: Verification and biometric applications
Oleg Komogortsev, Corey Holland, Sampath Jayarathna, Alex Karpov
Article No.: 27
DOI: 10.1145/2536764.2536774

This article assesses the ability of a two-dimensional (2D) linear homeomorphic oculomotor plant mathematical model to simulate normal human saccades on a 2D plane. The proposed model is driven by a simplified pulse-step neuronal control signal...
