PROBLEM TO BE SOLVED: To minimize a recognition error of a numerical value designated by a user using a space perception sensor and to achieve a stress-free operation.SOLUTION: A state determination part 121 switches an operating state to a quantity adjustment state, when the operating state is an object selective state and a space perception sensor 300 recognizes a user's both hands. When the operating state is in the quantity adjustment state, a gesture determination part 125 analyzes a gesture of one hand to another hand of the user recognized by the space perception sensor 300, and determines the quantity specified by the user.SELECTED DRAWING: Figure 1 |
