Assessing Spatiotemporal Context of User’s Daily Behavior to Facilitate Subtle Deviation

In this paper, we propose a guideline for selecting information that is suitable as a trigger to facilitate subtle deviation. In general, individuals tend to recognize and remember a place by noticing unique and subtle elements in it. To enhance place-element recognition, it is preferable to notice unknown objects and/or observe remarkable scenery by walking around the place and visiting various sites within it. This activity , however, is often difficult because a subject's behavior in most places is routine and resistant to the unordinary (i.e., a person may follow the same route every day when attending school or visiting a shop). To encourage subtle deviation to find new elements, the proposed system employs a method wherein information is selected and provided to a user based on the spatiotem-poral context of the user's daily behavior. This objective is achieved by analyzing the path that the subject repeatedly follows.
