Publication number: 20240023897Abstract: 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.Type: ApplicationFiled: September 26, 2023Publication date: January 25, 2024Applicant: TEGWAY CO., LTD.Inventors: Kyoungsoo YI, Ockkyun OH

Patent number: 11612358Abstract: 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.Type: GrantFiled: August 5, 2021Date of Patent: March 28, 2023Assignee: TEGWAY CO., LTD.Inventors: Kyoungsoo Yi, Ockkyun Oh, Jong Ok Ko

Patent number: 11207032Abstract: 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 being opposite to the outputted thermal feedback.Type: GrantFiled: July 1, 2020Date of Patent: December 28, 2021Assignee: TEGWAY CO., LTD.Inventors: Kyoungsoo Yi, Ockkyun Oh
