It is expected that virtual reality (VR) experiences will often be performed in a relaxed posture, while sitting on a reclining seat at home or in the supine position on a bed in rehabilitation institutions. However, there is no clear knowledge on the subject of how humans perceive the horizontal plane of a virtual world while using HMDs in reclining postures. In this study, we investigated how the angle of the subjective horizontal plane changes in relation to the angle of the upper body in a reclining seat. As a result, we found that the angle of the perceived horizontal plane changes depending on the angle of the upper body, and the physical direction of gravity has little effect on this perception.

If wind is used, users need not use additional devices, and some studies have concluded that using wind and presenting a video simultaneously improves this sense of presence. In these studies, however, wind sources were sparsely arranged; with such an arrangement, it is unclear whether an accurate environment was reproduced. A number of variables including gender, age, and the facial hit rate may affect the perception of wind direction. In the proposed study, we have examined the effect of these variables on perception of wind direction by the head.

Human Olfactory Displays and Interfaces

Because we sense smells through the air, the role of an olfactory display is to make scented air from odor materials in a stocked form with the desired components and concentration and to deliver the scented air to the human olfactory organ. This chapter provides a survey of various technologies, categorized by scent generation methods and scent delivery methods, used to construct an olfactory display. For scent generation methods, vaporization/atomization techniques, scent switching techniques, and formulation techniques are discussed. For scent delivery methods, several approaches to convey odor material from the scent generator to the nose are discussed. In addition, a brief description of evaluation methods of olfactory displays is provided.

As an example of this design approach, we built a VR system that provides the experience of Mochitsuki. We designed a more durable system than the initial prototype. With this configuration, direct interactions between the user and the system are all performed by physical devices to ensure the quality of experience, while the parameters affecting the experience can be controlled by electronic devices and mechanisms.
