Abstract
While hand-held computing devices are capable of rendering advanced 3D graphics and processing of multimedia data, they are not designed to provide and induce sufficient sense of immersion and presence for virtual reality. In this paper, we propose minimal requirements for realizing VR on a hand-held device. Furthermore, based on the proposed requirements, we have designed and implemented a low cost hand-held VR platform by adding multimodal sensors and display components to a hand-held PC. The platform enables a motion based interface, an essential part of realizing VR on a small hand-held device, and provides outputs in three modalities, visual, aural and tactile/haptic for a reasonable sensory experience. We showcase our platform and demonstrate the possibilities of hand-hand VR through three VR applications: a typical virtual walkthrough, a 3D multimedia contents browser, and a motion based racing game
Highlights
One easy way to realize “virtual reality (VR)” that provides an immersive and multimodal sensory experience is to employ expensive sensors and large scale displays such as fully immersive displays, 6DOF trackers, motion simulators, 5.1 surround sound systems, and haptic devices
We hope and believe that hand-held virtual reality contents can exhibit sufficient immersive and sensory experience, if the platform was built with our proposed requirements and employed the style of interaction enabled through the proposed platform
We demonstrate our ideas by presenting our own implementation of a hand-held VR platform, and applications
Summary
One easy way to realize “virtual reality (VR)” that provides an immersive and multimodal sensory experience is to employ expensive sensors and large scale displays such as fully immersive displays, 6DOF trackers, motion simulators, 5.1 surround sound systems, and haptic devices. Several researchers have used cell phones and PDA’s for VR and AR applications [1, 2], and hand-held console grade games have become a reality (e.g. SONY PSP®). In this paper, based on research by others and our own, we attempt to derive minimal and general requirements for a hand-held platform for virtual reality. We hope and believe that hand-held virtual reality contents can exhibit sufficient immersive and sensory experience, if the platform was built with our proposed requirements and employed the style of interaction enabled through the proposed platform. We propose several requirements for a hand-held device to support minimal level of immersion and sensory experience as a viable platform for VR.
