## Abstract

An input device is disclosed. An input device comprises a display unit, an input unit, a load detection unit and a control unit. The display unit is configured to display an object of a folder with a hierarchical structure. The load detection unit is configured to detect a pressing load with respect to the input unit corresponding to the location of the object of the folder that is displayed on the display unit. The control unit opens and closes folders based on a change in the pressing load.

## Claims

### Claim 1

An input device, comprising:
a display configured to display a first object;
a load detector configured to detect a pressing load applied to the input device; and
a controller, wherein
in response to the pressing load satisfying a predetermined load for a period of time, the controller displays a second object.

### Claim 2 (depends on 1)

The input device according to claim 1, wherein
the period of time is a predetermined period of time for the load detector to determine that an input is received.

### Claim 3

A method of controlling an input device, the method comprising;
displaying a first object;
detecting a pressing load applied to the input device; and
in response to the pressing load satisfying a predetermined load for a period of time, displaying a second object.

### Claim 4 (depends on 3)

The method of controlling an input device according to claim 3, wherein
the period of time is a predetermined period of time for the load detector to determine that an input is received.
