An ECU device which estimates a length of a lower limb of a seated person who is seated in a vehicle seat is shown. The ECU device includes the following. A thigh angle information obtainer obtains information regarding a thigh angle of the seated person. A back knee angle information obtainer obtains information regarding a back knee angle of the seated person. An estimator estimates the length of the lower limb of the seated person based on the information regarding the thigh angle obtained by the thigh angle information obtainer and information regarding the back knee angle obtained by the back knee angle information obtainer.

There is provided a measurement device which is operable to measure a movable range of a finger easily in a further small size and a measurement method, and a program. The measurement device includes: a first linear motion mechanism which has a contacting part contacting a back of a hand and linearly moves along a longitudinal direction, the back of the hand serving as reference of measurement; a second linear motion mechanism which moves together with a finger targeted for the measurement and linearly moves along a longitudinal direction; and a rotation mechanism which rotatably connects one end of the first linear motion mechanism and one end of the second linear motion mechanism and has a sensor detecting a rotation amount of the second linear motion mechanism, the second linear motion mechanism rotating with respect to the first linear motion mechanism. Then, current values of the rotation amount detected by the sensor are obtained, and a measured value of a joint angle is calculated from a threshold value updated by a maximum value of the current values, the measured value showing a movable range of the finger. The present technology is applicable to, for example, a measurement device which measures a movable range of a finger.
