    An Augmented Reality and Virtual Reality Pillar for Exhibitions: A Subjective Exploration
    (The Eurographics Association, 2017) See, Zi Siang; Sunar, Mohd Shahrizal; Billinghurst, Mark; Dey, Arindam; Santano, Delas; Esmaeili, Human; Thwaites, Harold; Robert W. Lindeman and Gerd Bruder and Daisuke Iwai
    This paper presents the development of an Augmented Reality (AR) and Virtual Reality (AR) pillar, a novel approach for showing AR and VR content in a public setting. A pillar in a public exhibition venue was converted to a four-sided AR and VR showcase, and a cultural heritage exhibit of ''Boatbuilders of Pangkor'' was shown. Multimedia tablets and mobile AR head-mountdisplays (HMDs) were provided for visitors to experience multisensory AR and VR content demonstrated on the pillar. The content included AR-based videos, maps, images and text, and VR experiences that allowed visitors to view reconstructed 3D subjects and remote locations in a 360° virtual environment. In this paper, we describe the prototype system, a user evaluation study and directions for future work.

    On the Analysis of Acoustic Distance Perception in a Head Mounted Display
    (The Eurographics Association, 2017) Dollack, Felix; Imbery, Christina; Bitzer, Jörg; Robert W. Lindeman and Gerd Bruder and Daisuke Iwai
    Recent work has shown that distance perception in virtual reality is different from reality. Several studies have tried to quantify the discrepancy between virtual and real visual distance perception but only little work was done on how visual stimuli affect acoustic distance perception in virtual environments. The present study investigates how a visual stimulus effects acoustic distance perception in virtual environments. Virtual sound sources based on binaural room impulse response (BRIR) measurements made from distances ranging from 0.9 to 4.9 m in a lecture room were used as auditory stimuli. Visual stimulation was done using a head mounted display (HMD). Participants were asked to estimate egocentric distance to the sound source in two conditions: auditory with GUI (A), auditory with HMD (A+V). Each condition was presented within its own block to a total of eight participants. We found that a systematical offset is introduced by the visual stimulus.
