WiMi Developed Holographic Eye-Tracking Focusing System

Beijing, Jan. 29, 2024 (GLOBE NEWSWIRE) -- WiMi Hologram Cloud Inc. (NASDAQ: WIMI) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that it has been focusing on solving the bottleneck of holographic head-mounted display technology, challenging the traditional display mode and enhancing the overall user experience. WiMi's HoloAR Lens was developed by using a holographic eye-tracking focusing system, an optical system with adjustable pupil distance, and real-time FOV digital control in a product that involves optical engineering, computer vision, human-computer interaction, etc. The core innovation of the HoloAR Lens is that WiMi developed a holographic eye-tracking focusing system. It uses advanced computer vision technology that captures the user's eye movements in real-time by embedding an eye-tracking camera in the device. This data is transmitted to the built-in processing unit and analyzed with the help of algorithms to determine the user's focus position.

Unlike traditional holographic displays, this system calculates holograms at actual time adjustments without any dynamic optical components. This is achieved by using a spatial light modulator (SLM). This allows the system to control focus instantaneously, eliminating the delay and discomfort associated with traditional mechanical adjustments.

The holographic eye-tracking focusing system avoids the use of any mechanical moving parts. Compared to traditional holographic head-mounted displays, this design simplifies the device, reduces its weight, and improves its stability. At the same time, noise and vibration from moving mechanical parts are eliminated, improving the overall user experience.

To solve the problem of users' different pupil distances, WiMi's HoloAR Lens adopted the optical structure system with adjustable pupil distance and an optical metric with independent intellectual property rights. Adjusting the position and parameters of the optical elements enables each user to adjust the pupil distance according to the characteristics of his/her own eyes, thus further improving comfort when wearing it. The innovation of the optical structure is an important step forward in solving the problem of viewing discomfort in holographic displays.
