Investigation of an Ambient and Pervasive Smart Wall Calendar with Event Suggestions

People have been using calendars for thousands of years to schedule appointments and to keep track of their daily lives. Today, calendars have a variety of form factors, including wall, desk, and digital calendars that all have specific advantages and limitations. In previous work, we envisioned Caloo a smart wall calendar. In addition to displaying users' schedule, Caloo suggests nearby events. Caloo aims to increase the awareness regarding appointments and to support to be active through event suggestions. In this paper, we present the implementation and insights of the developed smart calendar. We deployed Caloo for four weeks in participants' homes. Our results show that all participants are eager to use the developed system. Our analysis further indicates that the usage of Caloo makes users more open to attending local events. Results also suggest that it is important to provide fine-grained control over event suggestions, enable users to define when events should be suggested as well as to prioritize events.
