1. A viscoelasticity measurement system comprising:
a measurement apparatus including a movable unit configured to be continuously pressed against a measurement object, a first sensor configured to output 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 configured to output reactive force information corresponding to a reactive force applied to the contact portion of the movable unit with respect to the measurement object;
a processor configured to calculate, based on the acceleration information and the reactive force information, a complex elastic modulus of the measurement object, a delay time difference between the acceleration information and the reactive force information, and a viscosity property, and calculate first information on an elastic component of the measurement object and second information on a viscosity component of the measurement object;
a display apparatus configured to display the first information and the second information.
