Abstract

Provided is a stereo tactile sensation providing device including a plurality of actuators spaced apart from each other, a connector for mounting the plurality of actuators thereon and including three or more tactile regions, and a controller for applying an operation signal to the actuators, wherein the controller applies a first signal for controlling the actuators to stimulate first tactile cells above a threshold, and a second signal for controlling the actuators to stimulate second tactile cells above the threshold, and wherein the connector provides synthetic tactile sensations generated by the plurality of actuators.

First claim

The invention claimed is:

1. A stereo tactile sensation providing device, the device comprising:
a connector connected to a plurality of actuators and including a plurality of tactile regions;
a controller for applying an operation signal to the plurality of actuators; and
a tuner for transmitting a control signal to the controller,
wherein the controller receives the control signal and applies the operation signal to the plurality of actuators,
wherein the connector provides different tactile sensations for each of the plurality of tactile regions including a tactile region between the plurality of actuators and a tactile region other than between the plurality of actuators,
wherein the tuner is an application or a tuning tool, the tuning tool comprising any one of scrolls, buttons, and an equalizer, and
wherein the application or the tuning tool controls at least one of the tactile sensations or intensities of the tactile sensations, and the plurality of tactile regions.

2. The device of claim 1 , wherein the connector provides the tactile sensations comprising at least two of vibration, smoothness, bluntness, tapping, roughness, and sharpness.

3. The device of claim 1 , wherein fixing guides are mounted on the connector, and
wherein the plurality of actuators are supported by the fixing guides to be fixed on the connector.

4. The device of claim 1 , wherein recesses are provided in the connector, and
wherein the plurality of actuators are rested and fixed in the recesses.

5. The device of claim 1 , wherein through-holes are provided to penetrate the connector, and
wherein the plurality of actuators are fitted through the through-holes.

6. The device of claim 1 , wherein the connector is made of plastic, metal, glass, rubber, or wood.

7. The device of claim 1 , wherein the plurality of actuators are mounted on the connector via a coupling means comprising knobs or an adhesive material.

8. The device of claim 1 , wherein at least a part of the connector is connected to a target product to provide the tactile sensations to a user through the target product.

9. The device of claim 1 , wherein at least two of the plurality of actuators are mounted on the connector at different angles to provide the tactile sensations in different directions.

10. The device of claim 1 , wherein the operation signal includes a first signal for controlling each of the plurality of actuators to stimulate first tactile cells above a threshold, and a second signal for controlling each of the plurality of actuators to stimulate second tactile cells above the threshold.

11. The device of claim 1 , wherein the controller controls at least one of voltages, frequencies, and waveforms of the operation signal.

12. The device of claim 1 , wherein the first tactile cells comprise Merkel cells and Ruffini corpuscles as slow-adapting (SA) receptors, and
wherein the second tactile cells comprise Meissner corpuscles and Pacinian corpuscles as rapid-adapting (RA) receptors.
