 note = {Multiple photo-reflective sensors can measure skin deformation at the fingertips. Skin deformation can be used to estimate the contact force when the fingertip contacts an object. In a previous study, we developed a device that obtains additional distance information from the contacting surface. This device improved the accuracy of estimation. In addition, a photo-reflective sensor does not touch the contact surface between the fingertip and the object. Therefore, the device can estimate the contact force without changing the tactile sensation of the user. In this study, to evaluate the accuracy of the estimation by this device, we calculated the Mean Absolute Error (MAE) and the Mean Absolute Percentage Error (MAPE) of the estimated values. These have not been evaluated in previous studies., Multiple photo-reflective sensors can measure skin deformation at the fingertips.
