Abstract

An input device includes an operating surface at which touch operations relating to changing a display form of a display object are performed, a contact sensor configured to detect touch operations as to the operating surface, a pressure sensor configured to detect pressing operations as to the operating surface, a tactile feedback presentation element configured to present tactile feedback corresponding to operations detected by the touch sensor, and a tactile feedback controller configured to control the tactile feedback presented by the tactile feedback presentation element. In a case where an operation detected by the touch sensor is a specified operation specified beforehand out of the contact operations relating to changing the display form, the tactile feedback controller causes the tactile feedback presentation element to present tactile feedback corresponding to that specified operation.

First claim

What is claimed is:

1 . An input device, comprising:
an operating surface at which touch operations relating to changing a display form of a display object are performed; a contact sensor configured to detect touch operations as to the operating surface; a pressure sensor configured to detect pressing operations as to the operating surface; a tactile feedback presentation element configured to present tactile feedback corresponding to operations detected by the touch sensor; and a tactile feedback controller configured to control the tactile feedback presented by the tactile feedback presentation element, wherein, in a case where an operation detected by the touch sensor is a specified operation specified beforehand out of the contact operations relating to changing the display form, the tactile feedback controller causes the tactile feedback presentation element to present tactile feedback corresponding to that specified operation.

2 . The input device according to claim 1 ,
wherein the operations relating to changing the display form include operations relating to enlarging and reducing the display object, and the specified operation is an operation to enlarge or reduce the display object by a specified scale.

3 . The input device according to claim 1 ,
wherein the operations relating to changing the display form include operations relating to rotating the display object, and the specified operation is an operation to rotate the display object by a specified angle.

4 . The input device according to claim 2 ,
wherein, when the display object returns to the original display form, the tactile feedback controller causes the tactile feedback presentation element to present tactile feedback corresponding thereto.

5 . The input device according to claim 1 ,
wherein resolution for detecting the specified operation is changed between a case where pressure detected by the pressure sensor when the specified operation is performed is a predetermined value or above, and a case where the pressure is smaller than the predetermined value.

6 . The input device according to claim 5 ,
wherein frequency of presenting the tactile feedback is changed in accordance with the pressure in a case where pressure detected by the pressure sensor when the specified operation is performed is the predetermined value or above.
