How do you trigger learning by seeing? How do you encourage eco-conscious behaviors? How do you trigger health awareness? How do you encourage crime prevention? Shikake is a Japanese word that represents physical and/or psychological trigger for implicit or explicit behavior change to solve problems. The aim of this workshop is to gain a holistic understanding of Shikake, i.e.: Shikake principles Behavior change triggers Sustained behavior change Case studies Approaches to design simple and complex Shikake The merits of Shikakeological approach are summarized as four points; low expertise, low cost, wide range of target users, and long term continuous behavior changes. Developing a Shikake can be easier and less expensive than developing complicated engineering mechanism. These advantages allow people to use the Shikake approach to address immediate problems without requiring specific expertise. Another Shikake objective is to induce spontaneous behavior. When people feel controlled or forced by someone or something to do something, they never do that again. On the other hand, if people desire and enjoy changing their behavior, they would do it repeatedly. Shikake aims to change behavior through a continuous engagement and transformation process. The goal of Shikakeology is to codify the cause and effect of Shikake cases from physical and/or psychological points of view, and to establish a Shikake design methodology. To achieve this goal, this workshop invites Shikake studies to share the knowledge, methods, experiments and findings that demonstrate triggers that motivate people and lead to behavior changes. The fundamental research of Shikaleology is deeply related to Artificial Intelligence topics through: 1) interaction design of embodied-, situated-, and behavior-based intelligence, 2) definition of Shikake ontology and knowledge representation; 3) codifying Shikake cause and effect, and 4) formalizing intelligent and adaptive Shikake algorithms for reasoning, planning, and learning. Shikake can be viewed as an intelligence amplifier for new Artificial Intelligence platforms.
