Device-to-device communication framework supporting indoor positioning system for location-aware interactive applications

This paper proposes a device-to-device communication framework supporting indoor PS (positioning system) for location-aware interactive applications. The framework is useful for developing especially entertainment applications like ARG (Alternate Reality Game) that uses geographical data because such a game employs a virtual game world mixed with the real world and the framework supports indoor PS data based on Wi-Fi technology for that. In ARG, we can often use mobile devices as HID (human interface devices) of the game because modern mobile devices have GPS and several sensors like a touch panel, an acceleration sensor. Generally, a certain device is not designed to transmit its sensor data to other devices so that usually we can't use the device as any interface of a game running of a PC without making its dedicated interface programs. The proposed framework makes it possible to exchange sensor data including indoor PS data among several devices so that with the use of the framework, it is possible to develop entertainment applications like ARG easily without making any dedicated interface programs. To clarify the usefulness of the framework, this paper introduces one actual game and one prospective game example developed or to be developed using the framework.
