The electrostatic force haptic display device has the advantages of being easy to miniaturize and applicable to the mobile terminals such as smart phones, tablet computers and laptops; the electrostatic force haptic display method is low in computation complexity and particularly applicable to the mobile terminals such as tablet computers and mobile phones limited in computational capability, and good haptic experience can be obtained.

Description

technical field [0001] The invention belongs to the field of virtual reality, and in particular relates to an electrostatic force tactile reproduction device and an electrostatic force tactile reproduction method applied to mobile terminals. Background technique [0002] Tactile reproduction can provide people with a more realistic and intuitive interactive experience, and is currently a research hotspot in the field of virtual reality technology at home and abroad. Tactile reproduction plays an important role in fields such as education, online shopping, vision for the blind, and telemedicine. [0003] Jin-Hun Park of Pusan ​​National University in South Korea proposed a linear vibration sensor based on magnetic circuit design, which increases the magnetic force so that it can increase the force transmitted by the linear vibrator and enhance the vibration intensity of the linear vibrator while ensuring fast response. , but has limited effect on haptic simulation. A transp...
