1. VR Display Optics
With a pancake solution, the VR display optical system of AAC Technologies takes pride in five major technical features: thinner host, wider field of view, more effective suppression of Ghost, more friendly for myopia, and clear edge image quality, which can enable instant image beautification and slimming for VR experiences and provide consumers with better images through a thinner and lighter device.
2. AR Display Optics
Following the mainstream trend of using diffractive optical waveguides for AR optical imaging, AAC Technologies and Dispelix jointly developed and manufactured the new-generation full-color optical waveguide glasses. These excellent glasses feature friendlier permeability and industrial design, more potential process space, better color reproduction and brightness uniformity, and other advantages, balancing large field of view, and high image quality with single-layer optical waveguide glass, bringing consumers clearer images and a lighter wearing experience
AAC single-layer optical waveguide lenses feature superior picture reproduction.
3. AR/VR Camera Modules
To continuously improve the immersive experiences for users, AR/VR devices can integrate up to 16 cameras. Boasting a rich and diverse lens product portfolio, strong module manufacturing capabilities, industry-leading high-precision molding processes, and professional algorithms, AAC Technologies can assist clients in realizing the application of more cameras and developing the technology ecosystem through vertical integration.
Auditory
1. AR/VR Audio Systems
AAC Technologies has been accumulating sound technologies for 30 years and is recently developing rapidly in the field of AR/VR audio. Its world-leading comprehensive acoustic solution can meet the diverse needs of customers with high-energy and high-density speakers, proprietary audio algorithms, and professional tuning services. It can continue to create differentiated value for users with its powerful hardware (SLS acoustic platform and master-level speakers), software (multi-scenario targeted algorithms), and extremely precise professional tuning services.
AAC comprehensive acoustic solution
For the unique product requirements of AR/VR, AAC Technologies can perform post-processing on various sound sources to ensure the original sound characteristics and expand the sound field range to enhance the sense of full immersion. It can distinguish sounds and improve the sound positioning to better reproduce the true experience of the scene.
In addition, it allows low-latency 360° head tracking and horizontal displacement head tracking to avoid sound misalignment. It can leverage coaxial technology and algorithm enhancement technology to further enhance sound, and private sound field technology to reduce sound leakage effectively, bringing users immersive audio experiences with richer spatial information and more privacy.
2. AR/VR Voice Pickup Solution
The special use cases of AR/VR products make them extremely demanding on directional human voice pickup and Low-power speech recognition. AAC Technologies has combined excellent noise reduction technology and precise directional voice pick-up solution with small size, high performance, low power consumption, and smarter microphone components to meet the needs of consumers.
Haptics
VR devices are mostly used to play games and watch movies. The vibrations of wide-band actuators and force feedback of adaptive triggers of controllers, the main interactive tool of VR, can improve game experiences in the future.
To bring more realistic haptics to the user experience, AAC Technologies has upgraded its adaptive trigger solution, reasserting its commitment to provide users with triggers featuring large stalling torques, low power consumption, full range (force and stroke) controllability, stronger button push and pull capabilities, clearer haptic experience, smooth and latency-free force feedback, silence and low noise.
RichTap® AR/VR haptics interaction solution
In the end, users are provided with multi-dimensional, full-scene, and high-quality haptic experiences through the realization of dynamic interactive control, real-time preview of integrated tuning, adaptive force trigger and vibration linkage control, wide-frequency asynchronous vibration and multi-channel control of left and right controllers.
Highlight 2: AAC Technologies Debuts Its Smart Sensors and a Full Range of SSE Products
At Sensor Shenzhen 2023, AAC Technologies exhibited its full range of SSE products, including product modules of MEMS microphones, inertial and RF products, MEMS speakers, airflow sensors, driver chips, and barometric pressure sensors. It has gained the attention of exhibitors with high-performance microphone modules, automotive microphone modules, RF front-end devices, inertial chips and modules, high-precision barometric pressure sensors, and other key products, as well as directional microphones, airflow sensors, and other distinctive product series.
As an invited guest at the exhibition, Mr. Wu Zhijiang, General Manager of the Sensor and Semiconductor Business Unit of AAC Technologies, delivered a keynote speech titled Sensor Solution Empowering the Wearable Market, in which he shared his insights on the development status, core technology trends, and application scenarios of the smart wearable device market, and introduced the applications of high-performance sensors and diversified solutions of AAC Technologies in TWS, smartwatches and smartbands, AR/VR, and other fields.
Mr. Wu said the integrated software and hardware solutions of AAC Technologies can meet the needs of users and partner manufacturers for wearable devices with multifunctionality, high integration, and high-performance experiences. AAC Technologies strives to the utmost of its strength to empower the industry and work with partners to promote the high-quality development of the wearable market.
It also exhibited many eye-catching and popular optical products. Its perfect layout and innovative technical strength in optical products have been demonstrated by the assembly of its WLG, optical lenses, actuators, camera modules, and other bestsellers. It is worth mentioning that compared with other glass molding technologies, its unique WLG technology has obvious advantages in terms of optical performance, optical precision, lens structure, lens thickness, and ultimate performance. AAC Technologies has impressed the audience with the exhibited WLG glass-plastic hybrid lenses, which can achieve more realistic and vivid color reproduction and a clearer low-light shooting experience.
