MobiTip: Using Bluetooth as a Mediator of Social Context
Åsa Rudström, Martin G.A. Svensson, Rickard Cöster, Kristina Höök · 2004
MobiTip is a social mobile service where comments or tips given by one person are made available to another when user devices connect on the fly, when users approach connection hotspots, or on demand. Bluetooth connectivity is used to form a social space of nearby devices that is used as key input for the collaborative filtering of tips. The social space is visualized to show other users nearby, thereby illustrating where tips come from and why they are presented at some particular point in time.
