Proposal of a Method for User Device Linkage by Invitation to Web System ID

Abstract

Much research has been conducted on community support using Web assistance systems that do not constrain users temporally and spatially, and onsite systems which aid real world activities such as event spaces or offline meetings. To use the Web assistance system by a user device onsite, it is necessary to link the user device ID to the user ID of the Web system. This paper describes such a device linkage method that aims to achieve linkage based on social relations among users. A device linked user can recommend and invite non-linked friends to the onsite system. This method requires no previous actions by prospective onsite system users, and reduces the burden of onsite managers. In this paper, user scenarios are analyzed and the device linkage system is implemented, being carefully designed to maintain reliability based on social relationships. A field-test of a conference demonstrates its effectiveness.
