This research proposes a quantification method for tactile evaluation by hierarchically classify tactile sensations into three groups named low-order of tactile sensation (LTS), high-order of tactile sensation (HTS) and desired tactile sensation (DTS). A sensory evaluation was conducted and factor analysis was performed to extract the common potential factors in each group. Next, multiple regression analysis was used to determine and examine the relationship between LTS-HTS, and HTS-DTS. Then, multiple physical quantities for quantification were measured. After that, the LTS factors were quantified by using the measured physical quantities. As a result, DTS adjectives were also quantified. Lastly, a verification test was conducted and the result showed that the proposed method may possibly evaluate unknown samples' tactile sensation from measured physical quantities.
