correlation coefficient, object-user association In this paper, we study a method of associating a person and an object utilized by him/her in real-time and an adhoc manner. The correlation coefficient is utilized to represent the proximity of the acceleration signal patterns from wearable sensors on different parts of the body and sensor augmented daily objects. The coefficients are evaluated in terms of the accuracy of the association and different varieties of calculating the correlation along 3D acceleration axes are studied. Also, the effects of the size of the time window and the sampling interval are examined. 1
