Abstract
In general, verval orders from a user are simplified or shortened and contain ambiguities. For example, an order "where?" issued by a user may mean the place of carrot when he/she is cooking or may mean the place of sugar when he/she is making coffee. In this paper, we propose a context-aware work support system, which provides appropriate services depending on human action context. The ambiguities of user orders are resolved by recognizing human actions using sensors embedded in the environments. We conducted experiments with subjects and confirmed that the proposed system provides appropriate services according to user action context.
