It is reported that WIMI (NASDAQ: WIMI) has developed a gesture control system based on sensor-based Electro-Holography technology. The sensor-based gesture interaction technology can realize the interaction between the user and the electronic holographic (EH) image, and improve the user's interactive experience. The realization of gesture interaction technology requires a combination of various technologies, including sensors, digital signal processing, gesture recognition, control commands and other technologies.

The interaction technology of WIMI's sensor-based electronic holography (EH) gesture control system can realize the interaction between users and three-dimensional holograms. It uses sensors and computer algorithms to detect and recognize the user's gestures, so as to realize the control and operation of the holographic image. This uses sensors to capture the user's gestures, and uses infrared sensors, depth cameras and other devices to realize gesture recognition. These sensors can capture the user's gestures in real time, then convert them into digital signals, and then process and analyze them through algorithms, and finally realize the control and operation of holographic images.

WIMI Electronic Holography (EH) is a method that uses electrical signals and optical technology to generate three-dimensional holograms. Its basic logic is to use computer-generated digital signals to control the light source, so that the light passes through the data of the recorded object, and then passes through a series of optical elements to form a real three-dimensional image.

Electron holography (EH) needs to scan or record the object with a laser light source first, and store the recorded optical information in the digital three-dimensional image data. These digital signals are then converted into electrical signals, and parameters such as the intensity, phase, and frequency of the light source are adjusted through an electrical controller to accurately reproduce the shape and color of the original object. Eventually, these rays will be reconstructed through optical elements such as lenses and mirrors to form a real three-dimensional image. The advantage of WIMI's electronic holographic technology (EH) is that it can generate high-quality, high-resolution three-dimensional holographic images with a strong sense of reality and three-dimensionality. It has a wide range of applications in medicine, engineering, entertainment and other fields, such as three-dimensional imaging of internal organs of the human body, visualization of engineering design, etc.

WIMI's sensor-based electronic holography (EH) gesture control system uses a phase-modulated SLM, a laser with a wavelength of 1nm is used as a light source, and a motion sensor is an interactive interface for holographic objects. The holographic 3D image is projected in front of the SLM as a real image to enhance its visibility, and it can be observed on the image sensor of the camera, and the holographic 3D image can be easily converted into a virtual image. By the compiler, with single floating-point calculation precision.


WIMI's (NASDAQ:WIMI) sensor-based electronic holography (EH) gesture interaction technology includes the following steps:
Collect gesture data: use sensors, such as infrared sensors, depth cameras and other devices, to capture user gestures. These sensors capture user gestures in real time and convert them into digital signals. Gesture data may include finger trajectory, gesture shape, speed, and the like.

Gesture signal processing: perform digital signal processing on gesture data, use digital signal processing algorithms, such as fast Fourier transform (FFT), wavelet transform (Wavelet Transform), etc., to filter, denoise, feature extract, etc. Extract useful information, such as gesture speed, direction, shape, etc.

Gesture recognition: Match the processed gesture data with a predefined gesture template to realize gesture recognition. A gesture template is usually pre-stored standard gesture data, which can be a gesture or a group of gestures. Gesture recognition algorithms include K-nearest neighbor algorithm, support vector machine, decision tree, etc.

Gesture control: Once the gesture is recognized, it can be converted into a control command to realize the control of the electronic hologram. For example, the three-dimensional holographic image can be moved, rotated, and scaled, or a different display mode can be selected through gestures.

Sensor-based electronic holographic technology gesture interaction technology has broad application prospects in the market. With the development of technologies such as virtual reality and augmented reality, 3D holographic images, as an important means of 3D visualization, have received more and more attention. The gesture interaction technology is an important means to realize the interaction between the user and the 3D holographic image, which can improve the user's interactive experience and operation efficiency.

WIMI's (NASDAQ:WIMI) sensor-based electronic holography (EH) gesture control system can be applied in games, entertainment, education, medical care and other fields. For example, in the medical field, doctors can use gesture interaction technology to manipulate 3D holographic images for surgical planning and operation. In the field of education, students can learn knowledge about human body structure, geography and landforms through gesture interaction technology. In the field of games and entertainment, players can use gesture interaction technology to control the movement, attack and other behaviors of game characters. With the further development and maturity of technology, WIMI WIMI Hologram's sensor-based electronic holography (EH) gesture control system will have a wider application space in the future.
