Abstract: The present disclosure relates to a force and complex vibration rendering system using a force feedback device and a wideband resonance actuator, and a method for providing force and complex vibration using the system. The force and complex vibration rendering system includes: a haptic device configured to be operated by a user to input an operation signal and configured to be able to provide reaction force or vibration to the user; a wideband resonance actuator installed at the haptic device and configured to output vibration at an output speed different from an output speed of vibration that is generated at the haptic device; an image provider configured to create and provide a virtual image, which includes at least one target object and an instrument object that is moved in correspondence to an operation signal input to an operation member, to the user; and a touch provider configured to calculate reaction force and vibration, which are generated at the instrument object when the instrument object collides with the target object in the virtual image, and control the haptic device and the wideband resonance actuator such that the calculated reaction force and vibration are applied to the user.
The force and complex vibration rendering system using a force feedback device and a wideband resonance actuator and a method for providing force and complex vibration using the system provide not only reaction force but wide bandwidth vibration to a user when a collision situation occurs in virtual simulation through a wideband resonance actuator that generates vibration at an output speed higher than a vibration output speed of the force feedback device of the haptic device, so the system and method have an advantage that it is possible to provide more real touch feedback to the user.-

Abstract: A first electronic device according to various embodiments may select one of a plurality of representation matrices and one of a plurality of measurement matrices on the basis of a pattern and/or feature of data received from a sensor. The selection of the representation matrix and the measurement matrix may be performed on the basis of machine learning. Based on the selected representation matrix and measurement matrix, the first electronic device may adaptively compress at least a portion of the data. A second electronic device according to various embodiments may restore compressed data on the basis of the result of selecting the representation matrix and the measurement matrix. By dynamically selecting the representation matrix and the measurement matrix on the basis of machine learning, it is possible to reduce an error in the data restored by the second electronic device (e.g., a restoration error).
