Embodiment 1

[0039] The tactile feedback device according to the first embodiment presents to the user the operation status at the time of the operation of rotating the spherical operation target image (virtual trackball) which is the GUI, as an operation feeling through the sense of touch. In other words, the tactile feedback device presents the operation status of the touch operation to the user when the user performs a touch operation on the operation object image displayed on the display unit as the object of the touch operation.

[0040] In fact, the trackball operation mainly includes the following two operations: the first operation in which the cursor is moved as much as the ball is rotated with the finger attached to the ball; During the rotation, the second operation is to keep moving the cursor etc. The tactile presentation device according to the first embodiment presents the status of the first operation and the second operation to the user as a sense of operation through the ...

Abstract

Provided is a tactile feedback device capable of giving feedback of an operation feeling to a user by tactilely presenting the state of rotating the operation object image when an operation to rotate an operation object image of a three-dimensional model to be operated is performed. The tactile prompting device includes a judging unit (105), which calculates a sliding distance on the touch screen (101) as a sliding distance; a display control unit (106), which converts the sliding distance into a rotation angle of the operation target image (3), and The operation target image (3) is displayed on the display unit (103) after rotation; the vibration control unit (107), when the rotation of the operation target image (3) starts, drives the vibration unit (102 ), as the sliding distance increases, the amplitude of the driving waveform is reduced, and the vibration unit (102) is controlled so that the amplitude of the driving waveform becomes 0 when a predetermined time elapses after the rotation of the operation object image (3) stops , thereby giving feedback on the reduction of the sense of resistance during the rotation operation of the operation object image (3).

Description

technical field [0001] The present invention is an invention that prompts the operation status when the virtual object displayed on the touch screen display is operated with a finger and a pen through the sense of touch. In particular, the present invention relates to a tactile presentation device and a tactile presentation method for presenting an operation status when an operation to rotate a virtual object is performed through tactile sensation. Background technique [0002] In recent years, touch panels have become popular as operation interfaces for smartphones, tablet PCs, personal computers, game consoles, and the like. These devices detect a position where a user touches a touch panel as a touch position, and operate a virtual object such as a GUI (Graphical user interface) displayed on the touch position. In general, unlike mechanical switches, a touch panel cannot provide a tactile sensation when operating a virtual object (operating sensation through tactile sens...
