This paper investigates an activity recognition method where the user wears stretch sensors made of conductive fabric on each part of the body. The system recognizes actions by measuring the circumference of body parts. The electrical resistivity of our stretch sensors changes in accordance with their expansion/shrinkage. The strengths of this approach are that the appearance of the user is not interfered with and that the sensor is less expensive than other sensors such as the myoelectric sensor. The results of evaluation confirmed that our method can recognize eight contexts by measuring the circumference of four body parts (abdominal region, waist, wrist, ankle) with 99.92% accuracy.
