Abstract: A method for providing a thermal feedback performed by a feedback device is disclosed. The method includes: applying an operating power to a thermoelectric element to start a thermoelectric operation for outputting a thermal feedback; stopping the application of the operating power to terminate the thermoelectric operation; and when the application of the operating power is stopped, applying a buffering power to the thermoelectric element to reduce a temperature returning speed of a contact surface so that a thermal inversion illusion is prevented. The thermal inversion illusion is a sensation felt by the user when a temperature of the contact surface returns to an initial temperature due to the termination of the thermoelectric operation, the thermal inversion illusion being opposite to the outputted thermal feedback.

Abstract: A method for providing a thermal feedback, includes executing a virtual reality application providing a virtual space that includes a virtual area to which an area temperature attribute is assigned, and a virtual object to which an object temperature attributed is assigned. An area event that reflects that a player character enters the virtual area is detected. A feedback device is controlled to output thermal feedback associated to the area temperature attribute when the area event is detected, the feedback device outputting the thermal feedback using a thermoelectric element performing a thermoelectric operation. An object event reflecting the player character is influenced by the virtual object is detected. The feedback device is controlled to override the thermal feedback associated to the area temperature attribute and output thermal feedback associated to the object temperature when the object is detected while the player character is in the virtual area.
