Referring to FIG. 5, a flow chart of a specific embodiment of a multi-directional search feedback method used by the system of the present invention is shown. The multi-directional search and feedback method 500 of the present invention comprises the following steps: First, step 510 is performed to capture the user's eye information through the eyeball information capturing device. In various embodiments, the eyeball information includes information on the number of blinks of the user for a predetermined period of time, or information about the interval between blinks of the user each time. The method of determining the blinking condition of the user by capturing the eyeball information may be, for example, "Real Time Eye Detection and Tracking Method for Driver Assistance System" published by Sayani Ghosh et al. in "Advancements of Medical Electronics" in January 2015. According to the article, this article is cited Incorporate this article.

Thereby, the user can activate or deactivate the multi-directional search and feedback system of the present invention at a discretion. For example, the preset event of shutting down the system is the number of blinks within a predetermined time, and the user can use the vibration array of the system of the present invention for a long time. When tactile fatigue is generated, and the vibration intensity generated by the vibration array cannot be clearly perceived, the user can turn off the multi-directional search and feedback system of the present invention through the blinking action in accordance with the shutdown system. In a specific embodiment, when the number of blinks of the user within a predetermined time is greater than the first threshold, the multi-directional search feedback system of the present invention is turned off. When the number of blinks of the user in a certain period of time is greater than the second threshold and less than the first threshold, the multi-directional search and feedback system of the present invention is activated.

Among them, the manual adjustment device can not only close or open the system of the present invention, but the user can also limit the maximum vibration amplitude of the vibration array through the manual adjustment device.

When the multi-directional search and feedback system of the present invention is in an activated state, step 530 is performed to detect and receive the microwave signal through the microwave sensing device. After detecting the microwave signal, step 540 is performed to determine the emission direction of the microwave signal and the signal strength of the microwave signal according to the received microwave signal.

Next, in step 550, the processor determines the vibration intensity of each vibration component of the vibration array according to the emission direction of the microwave signal and its signal strength. In a specific embodiment, each of the vibrating elements corresponds to a detecting direction corresponding to a microwave sensing element, and when a detecting direction corresponding to a vibrating element is closer to a transmitting direction of the microwave signal, Big The detection weight value makes the vibration component have a large vibration intensity. On the other hand, when the detection direction corresponding to a vibration component is farther away from the emission direction of the microwave signal, the vibration intensity of the vibration component is made smaller by giving a smaller detection weight value.

Thereby, the user can activate or deactivate the system of the present invention at his own discretion. For example, the preset event of shutting down the system is the number of blinks within a predetermined time, and the user can generate tactile fatigue when using the vibration array of the system of the present invention for a long time. When the vibration intensity generated by the vibration array is not clearly felt, the user can turn off the multi-directional search and feedback system of the present invention through the blinking action in accordance with the shutdown system. In a specific embodiment, when the number of blinks of the user within a predetermined time is greater than the first threshold, the multi-directional search feedback system of the present invention is turned off. When the number of blinks of the user in a certain period of time is greater than the second threshold and less than the first threshold, the multi-directional search and feedback system of the present invention is activated.

When the multi-directional search and feedback system of the present invention is in the activated state, step 630 is performed, and the processor determines the gaze direction of the user according to the captured eyeball information, and obtains the eye gaze direction information. Next, in step 640, the processor enables the microwave sensing component of the microwave sensing device in the eye gaze direction to detect and receive the microwave signal according to the eyeball gaze direction.

When the detection direction of the microwave sensing component of the microwave sensing device is closer to the eyeball gaze direction of the user, the detection weight of the detection direction is larger, and the microwave sensing component of the microwave sensing device When the corresponding detection direction is farther away from the user's eye gaze direction, the detection weight of the detection direction is smaller. In this way, the user can determine which direction to use as the main microwave through the direction of eyeball gaze. Signal detection direction. In this embodiment, each of the vibrating elements corresponds to a detecting direction of a microwave sensing component of the microwave sensing device, and when the detecting direction corresponding to the vibrating component is closer to the emitting direction of the microwave signal, Then, the vibration element has a large vibration intensity. Conversely, when the direction of detection of a vibrating element is farther away from the direction of emission of the microwave signal, the vibration intensity of the vibrating element is small. At the same time, the vibration intensity of each vibration component is proportional to the signal strength of the microwave signal detected by the corresponding microwave sensing component. When the signal strength of the microwave signal is strong, the vibration intensity of the vibration element is strong. When the signal strength of the microwave signal is weak, the vibration intensity of the vibration element is weak.

Then, after the processor calculates the vibration intensity of each of the vibrating elements, step 660 is performed to transmit the vibration intensity to the skin of the user through the vibrating elements of the vibrating array. In this way, the user's sense of touch can clearly grasp the emission direction of the microwave signal and the signal intensity through the vibration intensity of each vibration component, without observing the detection result of the microwave signal through visual or audible observation.

When the detection direction 836 is closer to the microwave signal emission direction 834 than the detection direction 838, the vibration component corresponding to the detection direction 836 will have a greater vibration intensity than the vibration component corresponding to the detection direction 838. When the microwave signal emitting direction 834 is between the detecting directions 836, 837, the vibration intensity of the vibrating element corresponding to the detecting directions 836, 837 will be generated according to the signal strength received by the microwave sensing element.
