For measuring hardness of an object, a measurement apparatus is pushed against the object and a degree of hardness calculation system calculates hardness based on information from the measurement apparatus. The measurement apparatus includes an acceleration sensor which outputs first information of acceleration of a contact area of the measurement apparatus, and a second sensor, such as a magnetic sensor or a pressure sensor, which outputs second information based on pressure applied to the contact area. The degree of hardness calculation system generates a second-derivative waveform by twice differentiating a waveform based on the output of the second sensor, compares the second-derivative waveform and the information of acceleration from the acceleration sensor, and calculates hardness of the object based on the comparison result.

The motor function estimating system 1000 has a memory unit 1260, a data processing unit 1220 (analyzing section), and a display unit 1400. The memory unit 1260 memorizes waveform data about the time change of fingers tapping motion that is obtained by a motion sensor attached to a subject person who does the fingers tapping motion that is repetition of the opening and closing motion of two fingers of one hand. The data processing unit 1220 analyzes the waveform data in the memory unit 1260. The display unit 1400 displays an analysis result. The data processing unit 1220 creates motion waveform based on waveform data, and plural characteristics based on the motion waveform. The data processing unit 1220 creates a motion disorder synthesis value that represents degree of motion disorder of the subject person by revising each of the plural characteristics based on characteristics of every age and synthesizing them.
