A method for providing a thermal feedback, performed by a feedback device. The feedback device outputs the thermal feedback, by transmitting a heat generated by a thermoelectric element, to a user via a contact surface contacting with a body part of the user. The method may include obtaining a feedback start message including a type of the thermal feedback, and when the type of the thermal feedback is a thermal grill feedback, outputting the thermal grill feedback by performing a thermal grill operation in which a heat generating operation and a heat absorbing operation is combined. The outputting of the thermal grill feedback may include applying a forward power to the thermoelectric element to perform the heat generating operation, applying a reverse power of which a current direction is opposite to the forward power to the thermoelectric element to perform the heat absorbing operation, and repeating the applying the forward power and the applying the reverse power alternatively.
