In this paper, we will present a framework for supporting local area communication and its prototype system. In the framework, wearable communications tools are to be used that have two features. One is automatic terminal-to-terminal communication, and the other is a HMD based information display. Terminal-to-terminal connection is automatically established among users who are near to each othe...

A between groups experiment was carried out to compare navigational strategies in a real environment and in a photorealistic computer graphics simulation of that environment. In this paper, a study that compares a real-world task situation to its computer graphics simulation counterpart is presented. The computer graphics simulation is based on photometry data acquired in the real-world space a...

OBJECTIVE The aim of this study was to replicate the finding that multisensory integration with a head-mounted display (HMD) is particularly difficult when a person is walking and hearing sound from a free-field speaker, and to extend the finding with a response method intended to reduce workload. BACKGROUND HMDs can support the information needs of workers whose work requires mobility, but s...

The Wearable Active Camera/Laser-Pointer (WACL) is a body-worn tool equipped with a camera/laser head capable of pan/tilt control to assist field workers in remote collaboration. A remote expert can freely observe the real workplace and directly point at targets with a laser spot. In our previous studies, however, it was found that advanced visual assist such as line drawings on images can supp...

OBJECTIVE The aim of this study was to assess how background visual motion and the relative movement of sound affect a head-mounted display (HMD) wearer's performance at a task requiring integration of auditory and visual information. BACKGROUND HMD users are often mobile. A commercially available speaker in a fixed location delivers auditory information affordably to the HMD user. However, p...

Many applications have used a Head-Mounted Display (HMD), such as in virtual and mixed realities, and tele-presence. The advantage of HMD systems is the ease of feeling a 3D world in the display of animation or movies. However, the field of view (FOV) of commercial HMD systems is too narrow for feeling immersion. The horizontal FOV of many commercial HMDs is around 60 degrees, significantly nar...

Cybersickness is often experienced when viewing virtual environments through head-mounted displays (HMDs). This study examined whether vection (i.e., illusory self-motion) and mismatches between perceived and physical head motions contribute to such adverse experiences. Observers made oscillatory yaw head rotations while viewing stereoscopic optic flow through an Oculus Rift HMD. Vection and cy...

This paper presents a communication system between humans and character agents, Agents on Robots (AoR), which combines the ability of expressions of character agents with the presence of robots. This system attaches an AR marker on mobile robots and allows users to communicate with CG agents through a Head Mounted Display (HMD). In our experiments, we compared the difference of impressions betw...

This paper introduces the concept and discusses the implications of immersive journalism, which is the production of news in a form in which people can gain firstperson experiences of the events or situation described in news stories. The fundamental idea of immersive journalism is to allow the participant, typically represented as a digital avatar, to actually enter a virtually recreated scena...

Legislation and product development in the USA has prompted an interest in mirror-use by traffic flaggers to improve awareness of vehicles approaching from behind. Helmet- and flagpole-mounted configurations were studied using a graphical approach with field verification studies by comparing fields of view, object magnifications, and human factors considerations. Plane and convex mirrors with d...
