摘要： The objective of the present invention is to provide a hardness meter which estimates hardness in a stable manner regardless of a compression strength. A hardness meter includes: a movable portion which is continuously pressed against an object to be measured; a sensor which outputs an output signal reflecting a reaction force at a part of the object to be measured; a motive force mechanism that causes the movable portion to perform a piston motion; a hardness estimating portion which estimates the hardness of the object on the basis of an alternating current component of the output signal, generated by the piston motion; a position estimating portion which estimates a measurement position information by shooting with a camera; and a hardness map display portion which maps and displays the hardness on a schematic diagram of the surface of a living body based on the measurement position information.

摘要： An object of the present invention is to provide a technique of quantitatively measuring physical properties including both viscosity and elasticity. A viscoelasticity measurement system includes a measurement apparatus, a processor, and a display apparatus. The measurement apparatus includes a movable unit continuously pressed against a measurement object, a first sensor outputting acceleration information corresponding to an acceleration of pressing-directional movement of a contact portion of the movable unit with respect to the measurement object, and a second sensor outputting reactive force information corresponding to a reactive force applied to the contact portion of the movable unit with respect to the measurement object. The processor calculates first information on an elasticity component of the measurement object and second information on a viscosity component of the measurement object based on the acceleration information and the reactive force information. The display apparatus displays the first information and the second information.

摘要： Provided is a technique with which it is possible to measure a subject's reaction by moving a visual target object in an arbitrarily defined direction as well as a horizontal direction. A dynamic visual acuity measuring device includes a projector projecting an index image pattern, a reflecting mirror reflecting light from the projector, a screen receiving light from the reflecting mirror and displaying the index image pattern, a movable casing holding and maintaining relative positions of the projector, the reflecting mirror, and the screen, a fixed casing supporting the movable casing, and a rotating shaft linking the movable casing rotatably to the fixed casing. In this device, the index image pattern displayed on the screen is moved in one direction by the reflecting mirror being displaced and a direction of movement of the index image pattern is changed in a coordinate system fixed to the fixed casing by the rotating shaft being rotated.

摘要： A technique for evaluating human cognitive and motor functions by a plurality of hand movement tasks is disclosed. A task execution method determines the execution order of a plurality of tasks which a test subject is caused to execute to acquire a characteristic quantity. A test subject group task database includes scores given in advance and characteristic quantities obtained from a plurality of tasks stored as past data corresponding to each of a plurality of test subjects. In a storage device, (1) a differentiation precision database for a case in which test subjects are divided into two groups by predetermined threshold value scores differentiated by the characteristic quantities, or (2) an estimation precision database for a case in which a score is estimated using the characteristic quantity for a predetermined score value is prepared for each of the tasks on the basis of the test subject group task database.
