Abstract
A tactile feedback device including a wearable device and a host is provided. The wearable device includes an acceleration sensor and an electrical stimulation generator. The acceleration sensor detects a movement state of a target object to obtain acceleration data. The electrical stimulation generator generates and transmits electrical stimulation to the target object according to a tactile control signal. The host includes a calculation circuit for calculating a displacement amount of the target object with respect to the host according to a signal attenuation amount of a radio wave signal and performing a calculation operation according to the displacement amount and the acceleration data to generate movement track information indicating a movement of the target object. The calculation circuit compares the movement track information with an object position in a display image to generate the tactile control signal. An operation method of the tactile feedback device is also provided.
