Mobile symbiotic interaction between a user and a Personal Assistant agent

In this paper, we propose a concept of an Mobile symbiotic interaction (MSI) between a user and a Personal Assistant (PA) which is an agent program that watches over the particular user using sensors deployed in a ubiquitous environment. The PA un derstands user's behavior through signals from the MSI. It is prototyped using the OMAS platform to aim at enhancing a relation between a user and his/her own PA by verbal interface and non-verbal interface which are realized in the proposed MSI.
