Document Type and Number:
Japanese Patent JP7239982
Kind Code:
B2
Abstract:
To provide a tactile sense evaluation system, a tactile sense evaluation method and a program that can evaluate a tactile sense with a high degree of accuracy even when an analyte and a pseudo finger relatively move in large stroke length.SOLUTION: A tactile sense evaluation system comprises: an image data acquisition unit 411 that acquires image data of a contact surface between an analyte and a pseudo finger 10 when the analyte or the pseudo finger 10 is operated in a state where the analyte is contacted with the pseudo finger 10 being an elastic body; a vibration information acquisition unit 412 that acquires vibration information; and an evaluation unit 413 that analyzes the image data and the vibration information to evaluate a tactile sense. The evaluation unit 413 partitions a relative movement distance or movement time of the pseudo finger 10 relative to the analyte, into an eccentricity confidence interval that is evaluated on the basis of eccentricity which is a change of area of the contact surface, a complex confidence interval that is evaluated on the basis of the eccentricity and the vibration information, and a vibration confidence interval that is evaluated on the basis of the vibration information, to evaluate the tactile sense.SELECTED DRAWING: Figure 3
