概要

In this paper, we propose a new Life Log system which estimates touching object based on a contact sound. We call it "Touch Log". A Life Log is a record of daily life. It is expected to obtain various Life Logs automatically. There are some devices including a camera, a microphone and a GPS for recording our actions. However, those devices have too rich information to be accepted in terms of privacy. In this research we focus on the sound when we touch/manipulate objects. If we can record touching objects in our daily lives, those can be used for a new types of Life Log. We recorded the touching sound by attaching the piezoelectric device on user's fingernail. Prototype system was constructed by using HMM (Hidden Markov Model). We show that our prototype system recognizes 12 different actions with 94.4% accuracy.
