Abstract
This study proposes gaze-based hand interaction, which is helpful for improving the user’s immersion in the production process of virtual reality content for the mobile platform, and analyzes efficiency through an experiment using a questionnaire. First, three-dimensional interactive content is produced for use in the proposed interaction experiment while presenting an experiential environment that gives users a high sense of immersion in the mobile virtual reality environment. This is designed to induce the tension and concentration of users in line with the immersive virtual reality environment. Additionally, a hand interaction method based on gaze—which is mainly used for the entry of mobile virtual reality content—is proposed as a design method for immersive mobile virtual reality environment. The user satisfaction level of the immersive environment provided by the proposed gaze-based hand interaction is analyzed through experiments in comparison with the general method that uses gaze only. Furthermore, detailed analysis is conducted by dividing the effects of the proposed interaction method on user’s psychology into positive factors such as immersion and interest and negative factors such as virtual reality (VR) sickness and dizziness. In this process, a new direction is proposed for improving the immersion of users in the production of mobile platform virtual reality content.
Highlights
With the development of various virtual reality devices and related technologies, an environment where general users can enjoy virtual reality content is being formed
The virtual reality content of the mobile platform was produced in accordance with the plan, and the accurate operation of the interaction process was verified based on the proposed input processing
This study proposed gaze-based hand interaction considering various psychological factors, such as immersion and VR sickness in the process of producing mobile platform virtual reality content
Summary
With the development of various virtual reality devices and related technologies, an environment where general users can enjoy virtual reality content is being formed. Content that enables users to feel an experience that is similar to reality is continuously needed, and various research and technical development related to virtual reality are being carried out to satisfy these needs. As the hardware performance of smart phones is increasing and low-priced mobile virtual reality HMDs are being propagated, a wide variety of mobile platform virtual reality content is being produced, and many related studies are being conducted. The popularization of mobile HMD is especially providing an environment where anyone can experience immersive virtual reality content anywhere. Mobile HMD requires the attachment of the mobile device inside the HMD, unlike personal computer (PC) or console platforms such as Oculus Rift
