Abstract
A haptic device according to one embodiment can comprise: a database unit for storing acoustic information or receiving the acoustic information from an external device; a control unit for converting the acoustic information into an electrical signal according to a predetermined pattern; a driving unit for generating a motion signal on the basis of the electrical signal; and a transfer unit for transferring a patterned tactile signal to a user by means of the motion signal.
Claims8
A haptic device, comprising:
- a database configured to store acoustic information or receive the acoustic information from an external device;
- a controller configured to convert the acoustic information into an electrical signal corresponding to a predetermined pattern;
- and
- a tactile actuator configured to provide a user with a patterned tactile signal, wherein the tactile actuator comprises:
- a driver configured to generate a motion signal based on the electrical signal;
- and
- a transmitter configured to transmit the patterned tactile signal to the user using the motion signal,
- wherein the controller is configured to determine one of a plurality of predetermined driving modes based on the acoustic information, and convert the acoustic information into the electrical signal having a frequency corresponding to the determined driving mode, and
- wherein the controller is configured to:
- determine a frequency of the electrical signal to be a first set frequency when the driving mode is a first set mode, and
- determine the frequency of the electrical signal to be a second set frequency when the driving mode is a set mode other than the first set mode, the second set frequency being lower than the first set frequency.
A method of converting an acoustic signal into a tactile signal using a haptic device, the haptic device comprising:
- a database configured to store acoustic information or receive the acoustic information from an external device;
- a controller configured to convert the acoustic information into an electrical signal corresponding to a predetermined pattern;
- and
- a tactile actuator configured to provide a user with a patterned tactile signal, and the method comprising:
- collecting driving information, the driving information including the acoustic information;
- determining one of a plurality of preset driving modes based on the collected driving information;
- determining the electrical signal to have a frequency corresponding to the determined driving mode;
- and
- applying the electrical signal to the tactile actuator.
