Implicit human computer interaction is based on the concept of using user activity in the real world as input to computers. Implicit HCI can help to reduce the problem of user input to wearable computers. In this paper, we report on wearable RFID technology that facilitates applications that are triggered by handling tagged physical objects. We also report on a case study in which the technology was integrated with an enterprise resource planning system to optimize work processes that involve physical objects.
