Making both first-person and third-person perspectives available in real world services

Abstract

In virtual worlds such as those realized through virtual reality technologies, the participants usually use the third-person perspective to see a wider area because the third-person perspective provides a variety of benefits. In this study, we propose an approach using both the first-person and third-person perspectives in real world applications, such as in smart city services, and evaluate the potential opportunities to offer more advanced digital services. We collect use cases and opinions for designing the prototype system's video presentation methods. Then, we implement prototype systems that enable the users to see from both the first-person and third-person perspectives by using webcams and a head-mounted display. Our approach makes it possible to develop new types of game-inspired smart city services that offer more opportunities through the multiple perspectives.
