With the rapid development of IOT technology and the increasing popularization of autonomous technology, a closely cooperative interaction relationship has been formed between humans and machines. However, most of the current human-computer interaction is presented through audio-visual technology, and the user's sensory experience cannot be touched in the sense of smell, taste and touch.
Haptic feedback technology:immersive interaction
Major Internet giants are fiercely competing for the new blue ocean of "meta-universe", want to build a "meta-universe" community that is closely linked with reality and has a greater sense of realism, mobilizing the user's sensory experience, and the sense of touch is particularly important.
In the field of industrial manufacturing, pressure-touch technology can reproduce the sense of touch for users through a series of actions such as force and vibration. This mechanical stimulation can be applied to assist in the creation and control of computer-simulated virtual scenes/objects. If you need more than just the keys to disappear, but also double to meet the user's sensory experience, then the haptic feedback technology can be for you to restore the real sense of touch.
For example, adding the application of haptic feedback technology in the HMI interface allows users to truly receive the physical sense of the display content on top of the audiovisual, texture and other information as if they were there, greatly enhancing the real sense of interaction. In the "meta-universe" community, the application of haptic feedback technology, the user can feel the touch of hand feedback when both sides shake hands, and can more truly experience the real sense of meeting with people. So, in the game and VR (virtual reality) with haptic feedback technology, will be the sense of presence points full.
Haptic feedback technology: make car driving safer
In the field of automobile driving, haptic feedback technology can issue different warnings to drivers through the steering wheel, pedals, seats, seat belts, etc., without producing audio-visual interference, enhancing driving safety.
As an example, if haptic feedback technology is added to the steering wheel of a car equipped with an ADAS system, the steering wheel will immediately vibrate when there is a lane departure, reminding the driver to pay attention to controlling the vehicle; or, the pedals are equipped with a triggered speeding warning function, which warns the driver of the danger of speeding in the form of haptic feedback; in the same way, pressure-touch feedback actuators equipped with the seats and seat belts can be used to help improve the driver's Similarly, haptic h feedback actuators in seats and seat belts can be used to help improve the driver's awareness of his or her surroundings and, to a certain extent, achieve "human-machine integration".
Haptic feedback actuators
Returning to the recent heated topic of "meta-universe", in order to realize the integration of reality and reality, it is necessary to have the support of haptic feedback technology. For this reason, AUDIOWELL has specially developed haptic feedback actuators to provide human-machine integration "neurons" for the "meta-universe". The products have high sensitivity, and combined with AI algorithms, they can simulate the feedback force in different scenarios, and create a sense of augmented reality for the assistance of the virtual scene or virtual objects. Creating a sense of augmented reality.
At the technical level, the most difficult thing to do with haptic feedback technology but must be done well: is to realize tactile feedback at the right time and the exact place. To address this point, AUDIOWELL analyzes the characteristics of the piezoelectric structure of high-frequency vibration and deformation, and conducts layer-by-layer testing to maximize the response time and achieve accurate haptic feedback at the set time to ensure the user experience.
AUDIOWELL haptic feedback actuator belongs to the operation type interaction actuator, the class belongs to the piezoelectric conversion element, with a wide range of applications, which can be used in HMI interface, VR, vibration warning system and so on.
The haptic feedback actuator utilizes the positive and negative piezoelectric effect of piezoelectric ceramics, which generates mechanical deformation when loaded with driving voltage, thus causing vibration. It consists of piezoelectric ceramics and metal substrate, with stable performance and compact size to meet the requirements of thin installation. It also has low power consumption, large amplitude, fast response speed, long service life, etc. Moreover, the amplitude and frequency can be changed freely by pulse control, which can cope with various vibration patterns.
