Referring to FIG. 2 , the glove 20 includes a glove body 21 . The glove body 21 is used to fit on the user's hand. The glove body 21 is made of insulating material. In this embodiment, the glove body 21 is made of rubber material. The glove body 21 has an inner surface 211 and an outer surface. When the glove 20 is worn on the user's hand, the surface that is in direct contact with the user's hand is defined as the inner surface 211 , and the surface that can be directly observed is defined as the outer surface. The inner surface 211 includes a first area 2111 and a second area 2112 that are joined to each other. When the glove 20 is worn on the user's hand, the area in contact with the fingers is defined as the first area 2111 , and the area in contact with the palm is defined as the second area 2112 .

Please continue to refer to FIG. 2 , the glove 20 further includes a plurality of first magnetic parts 22 . The plurality of first magnetic parts 22 are distributed in the first region 2111 , and the plurality of first magnetic parts 22 are arranged at intervals. Each of the first magnetic parts 22 is used to generate vibration. When the glove 20 is worn on the hand, the vibration generated by each first magnetic portion 22 is transmitted to each finger, so as to simulate the tactile sensation when the hand touches or grasps an object. The amplitude of vibration generated by each of the first magnetic parts 22 is variable, so as to transmit vibrations of different amplitudes to the fingers, so as to distinguish the tactile sensation when the hand grasps different objects.

Referring to FIG. 3 , each of the first magnetic portions 22 includes a first magnetic block 221 , a second magnetic block 222 and a haptic enhancement layer 223 that are stacked in sequence. When the glove 20 is worn on the hand, the haptic enhancement layer 223 is in direct contact with the fingers. Referring to FIG. 4 , the first magnetic block 221 and the second magnetic block 222 do not exhibit magnetism in a non-energized state, and the first magnetic block 221 and the second magnetic block 222 are directly attached. Referring to FIG. 3 again, the first magnetic block 221 and the second magnetic block 222 exhibit magnetism when voltages are respectively applied thereto. In this embodiment, by applying voltages to the first magnetic block 221 and the second magnetic block 222 respectively, the first magnetic block 221 and the second magnetic block 222 exhibit magnetism, and the first magnetic block 221 and the second magnetic block 222 The sides of 222 that are close to each other have opposite magnetic poles. In this embodiment, the side of the control first magnetic block 221 and the second magnetic block 222 that are close to each other is represented as N pole, and the side that is far away from each other is represented as S pole. According to the principle of "same-sex repulsion", a repulsive force is generated between the first magnetic block 221 and the second magnetic block 222 , so that the first magnetic block 221 and the second magnetic block 222 are separated.

Please continue to refer to FIG. 3 , the distance between the first magnetic block 221 and the second magnetic block 222 is proportional to the size of the repulsive force, and the size of the repulsive force is proportional to the magnetic force generated by the first magnetic block 221 and the second magnetic block 222 respectively, The magnetic force generated by the first magnetic block 221 and the second magnetic block 222 respectively is proportional to the magnitude of the voltage applied to the first magnetic block 221 and the second magnetic block 222 . By controlling the magnitude of the voltage applied to the first magnetic block 221 and the second magnetic block 222 , the distance and the repulsive force between the first magnetic block 221 and the second magnetic block 222 can be controlled, thereby controlling the first magnetic block 221 and the distance between the second magnetic blocks 222 . When the distance between the first magnetic block 221 and the second magnetic block 222 increases, the pressing force applied by the second magnetic block 222 and the haptic enhancement layer 223 to the finger increases, and the first magnetic block 221 and the second magnetic block 222 When the distance between them is reduced, the pressing force applied by the second magnetic block 222 and the haptic enhancement layer 223 to the fingers is reduced. Therefore, by controlling the magnitude of the voltage applied to the first magnetic block 221 and the second magnetic block 222, the second The magnitude of the squeezing force applied by the magnetic block 222 and the haptic enhancement layer 223 to the finger. When the magnitude of the voltage applied to the first magnetic block 221 and the second magnetic block 222 changes dynamically, the squeezing force applied to the finger by the second magnetic block 222 and the haptic enhancement layer 223 also changes synchronously and dynamically, which can form “vibration”. to simulate the tactile sensation of grasping objects in the hand.

When the glove 20 is worn on the hand, the plurality of raised structures 2232 are in direct contact with fingers. The base 2231 and the plurality of protruding structures 2232 are insulating materials. By arranging the plurality of protruding structures 2232, it is beneficial to reduce the contact area between the first magnetic portion 22 and the finger, thereby enhancing the tactile sensation. In this embodiment, the protruding structure 2232 is a semicircular structure protruding toward the finger direction. In other embodiments, the protruding structures 2232 can be semi-elliptical or other polygonal structures. The raised structure 2232 preferably has a flexible structure with a smooth surface, so as to help prevent sharp structures from scratching the fingers.

In another embodiment of the present invention, each of the first magnetic portions 22 may not include the haptic enhancement layer 223 . In the embodiment, when the glove 20 is worn on the hand, the second magnetic block 222 is in direct contact with the finger.

In this embodiment, each second magnetic force portion 23 is a permanent magnet, and the surface of each second magnetic force portion 23 in direct contact with the palm is the same magnetic pole S. The side of each first magnetic portion 22 close to the finger is the same as the magnetic pole of the second magnetic portion 23 that directly contacts the surface of the palm.

Please refer to FIG. 5 , when the finger is close to the palm, the distance between the first magnetic part 22 and the second magnetic part 23 is reduced, because the side of each first magnetic part 22 close to the finger and the second magnetic part 23 directly contact the surface of the palm The magnetic poles are the same, and there is a repulsive force between the first magnetic portion 22 and the second magnetic portion 23, so that there is resistance in the process of approaching the fingers to the palm to prevent the fingers and the palm from approaching. Since the process of approaching the finger and the palm is similar to the action when the hand grasps the object, the force of the object fed back to the hand when the hand grasps the object can be simulated by the resistance during the process of the finger approaching the palm. That is, the first magnetic portion 22 and the second magnetic portion 23 can simulate the tactile sensation when the hand grasps the object.
