Personal coordination server: a system infrastructure for designing pleasurable experience

In our daily lives, we have several personal devices carried with us everyday like a mobile phone. These devices contain more functionalities than now, and it is important to consider what these devices can do in the future. For example, these personal devices may be used to coordinate various appliances near a user. This paper proposes a personal coordination server that allows a user to control various information appliances near the user spontaneously. The personal coordination server personalizes the coordination of information appliances in several ways. The personalization can be used to design a user's experience. Our approach embeds preference rules that personalize the coordination among appliance into everyday artefacts such as seals, pens or keys. A user closes and departs the everyday artefacts to/from his/her personal devices to personalize the coordination explicitly. Also a designer embeds preference rules in cups and stuffed animals that a user uses in his/her daily activities or our surrounding environments to design the coordination for the user.
