Abstract

In this paper, we propose a method that estimates contact force to hard surface from a single visual image of a finger by using a neural network. In general, it is hard to estimate applied force to hard object only from visual images as the object surface hardly moves. In this paper, we focus on the human side. When persons push an object, posture of hand reflects how hard he/she pushes the surface. Observation of human body condition will tell the haptic information. We used the Convolutional Neural Network to make the system learn the relationship between the applied force and the finger posture. We created a neural network model individually. The evaluation result shows that a root mean square error from the actual force is approximately 0.5 N for the best case, which is 2.5% to the dynamic range (0–20 N) of applied force.
