Beijing, March 7, 2023 /PRNewswire/ — WIMI Hologram Cloud Inc. (NASDAQ: william) (“WiMi” or the “Company”), the world’s leading provider of holographic augmented reality (“AR”) technology, announced today that based on its Further exploration of applications in the field of game entertainment.
Compared with traditional games, the game scene interaction designed using the BCI-VR system will be more direct and intuitive, overcoming some limitations of walking around in a pure virtual reality environment. In particular, the BCI-VR system, which relies heavily on visual stimuli, allows users to achieve control in a VR environment by simply gazing or directly focusing on the object to be manipulated, thereby significantly enhancing the experience of game users.
WiMi’s game system combines BCI with VR to simulate and present a virtual game world, providing users with real-time feedback and response to BCI system commands. While providing more realistic, rich, active and motivating contextual feedback, the system provides direct and faster interaction for a more immersive gaming experience.
VR technology uses computers to construct a three-dimensional space model to generate a vast and perceivable virtual world that is dominated by vision, supplemented by hearing and touch. Users can create an immersive feeling and interact with the surrounding environment and things. At present, the interaction between people and the virtual environment is mainly carried out through the mouse, keyboard, joystick, etc., and the interaction methods are limited. This limitation hinders the immersive experience of VR, and new interactive ways can be developed to further enhance the user’s immersive experience.
Brain-computer interface is a new technology to communicate and control external information by establishing a direct connection pathway between the human brain and external devices, independent of conventional brain information output pathways (such as peripheral nerves and muscle tissue). It is a new type of external information communication and control technology. BCI collects EEG signals, performs a series of operations such as denoising, feature extraction, and classification and recognition on EEG signals to identify the intention of the brain, and finally converts the idea into control instructions for external devices, thereby realizing the direct function of controlling external devices through the brain.
The combination of BCI makes VR a feedback tool for the system. Compared with the traditional BCI feedback mode, VR can provide more realistic, flourishing, positive and motivating situational feedback. In addition, BCI can also be used as an input device for VR. Compared with traditional interaction methods such as mice and joysticks, brain-computer interfaces can provide more direct and faster input to the system and provide a more immersive experience.
BCI-VR is a typical closed-loop working system, which uses feedback to link the output with the input, and through the feedback, the participants are informed of the correctness of their expected behavior. The BCI-VR system consists of three main parts: the BCI system, the VR system, and the communication interface between the two systems.
BCI system includes EEG signal acquisition module and intelligent analysis software. The EEG signal collection module collects the scalp EEG signals of the subjects in a non-invasive way. The number of channels and electrode positions of the acquisition module will be adjusted according to the application. The EEG signal intelligent analysis software is responsible for processing EEG signals such as denoising, feature extraction, feature selection, and thinking state classification, and generates control commands to external devices.
The VR system can simulate and present a virtual world, provide users with real-time situational feedback, and respond to the control instructions of the BCI system in a timely manner.
As an input device, BCI mainly provides instructions in the BCI-VR system. Users can output efficiently, directly and quickly through brain activities. The BCI system then transmits this data to the VR system. While the VR system is mainly responsible for sensory stimulation and feedback tasks, it can present the sensory stimulation required by BCI, induce the physiological signals required by BCI as soon as possible, and provide meaningful feedback tasks to enable users to control BCI.
By combining BCI and VR technology, the complementary advantages of the two technologies can be realized. The BCI-VR system has broad application prospects in medical rehabilitation, games, entertainment, smart home, etc. Although some help is needed in the application process, with the continuous development of computer information technology, many technical bottlenecks will be overcome. The BCI-VR system will continue to improve and have a broader application prospect.
