Claim Text:
1. An application operation evaluating apparatus, comprising: a detecting unit that detects a measured pressing force of an application operation that uses a finger or a finger cot against an application target surface, based on pressing forces respectively obtained from a plurality of sensors that are provided at the application target surface, each of the sensors measuring load, the application target surface being provided with a plurality of sides; an estimating unit that estimates a pressed position of the application operation against the application target surface based on a ratio of the pressing forces respectively applied to the sides of the application target surface, the pressing forces respectively being applied to the sensors, the application operation being performed over the entirety of a predetermined area of the application target surface, the predetermined period being a set length of time, the detecting unit detecting the measured pressing force for every predetermined period to obtain a plurality of the measured pressing forces for different positions over the entirety of the predetermined area of the application target surface, respectively, and the estimating unit estimating a plurality of the pressed positions corresponding to the plurality of the measured pressing forces, respectively, in accordance with the application operation over the entirety of the predetermined area of the application target surface; a load distribution generating unit that generates a load distribution of the measured pressing forces and the respective pressed positions over the entirety of the predetermined area of the application target surface, respectively, in accordance with the application operation; a display unit that displays the load distribution obtained by the load distribution generating unit on a load distribution display part corresponding to the predetermined area of the application target surface, and displays a pressing force transition display part in which the measured pressing forces obtained for the every predetermined period are displayed in accordance with time such that the horizontal axis indicates time and the vertical axis indicates pressing force with a previously set appropriate range of the pressing force; and an evaluating unit that evaluates uniformity of application forces of the application operation for the different positions based on the measured pressing forces at the respective pressed positions.
