Input apparatus

An input apparatus having a touch sensor, said input apparatus comprising;

• a pressing load detection unit configured to detect a pressing load applied by a pressing object pressing the touch sensor;
• a contact area detection unit configured to detect a contact area of the pressing object on the touch sensor;
• a memory unit configured to store a pressing load threshold for receiving an input and a damage threshold higher than the pressing load threshold and the damage threshold being varied according to the contact area;
• a control unit configured to obtain the pressing load threshold and the damage threshold corresponding to the contact area detected by the contact area detection unit from the memory unit, and to receive the input when the pressing load detected by the contact area detection unit reaches the pressing load threshold and to generate a warning signal when the pressing load detected by the contact area detection unit reaches the damage threshold;
• and
• a notification unit configured to receive the warning signal from the control unit and to output a warning.
