Apparatus, system and method to deduce a force applied to a target object based on pressure data and characteristic hand data

Abstract

A contact information obtaining apparatus includes an applied-pressure direction deducing unit, a reaction calculation unit, and a determination unit. The applied-pressure direction deducing unit uses pressure data directed to pressure that a worker is applying to a target object by a hand of the worker, direction data directed to a direction concerning the hand measured and characteristic data that indicates a characteristic of the hand, to deduce an applied-pressure direction of the pressure that the hand is applying to the target object and a direction relative to the target object. The reaction calculation unit uses the pressure data and the deduced applied-pressure direction to calculate an applied-pressure reaction that is a reaction of the target object to the hand applying force to the target object. The determination unit determines whether or not the applied-pressure reaction is within a reference range.
