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

The present invention provides a tactile sense presentation device capable of providing, during an operation for rotating an operation object image of a three-dimensional model that is the operation object, operation feeling feedback to a user by presenting a tactile sense relative to the state in which the operation object image is being rotated. The present invention is provided with: a determination part (105) for calculating the distance over which a touch panel (101) was traced as the tracing distance; a display control part (106) for converting the tracing distance to an angle of rotation of an operation object image (3), rotating the operation object image (3), and displaying the image on a display part (103); and a vibration control part (107) for driving a vibration part (102) with a drive waveform of a predetermined amplitude and frequency when starting to rotate the operation object image (3), reducing the amplitude of the drive waveform in accordance with an increase in the tracing distance, and controlling the vibration part (102) so that the amplitude of the drive waveform becomes 0 at a predetermined time when stopping the rotation of the operation object image (3); thereby providing feedback on the reduction of a feeling of resistance at the time of 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 graphical user interface (GUI: Graphical user interface) displayed on the touch position. In general, unlike mechanical switches, a touch panel cannot provide the tactile sensation (operating sensation through touch) when oper...
