Abstract: A brainwave audio and video encoding and playing system is provided. Based on the research and understanding of the brainwaves, the relations of variations of the brainwaves corresponding to the melodies of the human voice senses and the relations of the human brainwaves to the colors is built so as to create rules for playing of the melodies by musical instrument and colors in a display so that variations of the brainwaves can be expressed by playing of music and display of colors and the messages of brainwaves could be transferred. As a result, the people have the same feeling to the testers.

Abstract: An AI test and analysis system for psychology preference is provided. By using brainwave detectors, the emotions and characters of the testers are connected. Variations from the brainwaves in pre-test and formal-test are used for analyzing of AI and big data as a base for determining human characters and emotions. These can be used to compensate insufficiency of conventional analysis thereabout. The methodology is widely used in various fields, such as mindfulness, human resource, potentials of people, and sensibilities of human, etc. Only data obtained from brainwave detectors are used to have tendencies and preference of the testers to various objects, while brainwaves are real physical data from the testers.

Abstract: A system for analyzing effects of mineral crystals to a human body and the method for performing the system comprises a helmet, a brainwave; a brainwave transceiver; a processor unit. The processor unit includes a processor transceiver, a brainwave calculating unit, a testing person database, a physiological and psychological effect database, a brainwave comparison module. In test, a specific mineral crystal is located in different distance from a testing person to test effects of the mineral crystal to the testing person; the testing person wears the helmet and the brainwave transceiver transmits measured brainwaves to the processor unit; and then the processor unit calculates statistical data about the brainwaves, and from the physiological and psychological effect database, effects of the mineral crystal to the testing person can be determined.

Abstract: A metaverse multimedia system based on user brainwaves causes that emotional messages, voice messages and color messages could be captured from the brainwaves of the users. The emotional messages are integrated to the role of the user in the metaverse space. Hence, the role in the metaverse can respond the emotions of the user, while the voice messages and color messages are integrated into the sceneries in the metaverse, which is selected by the user. As a result, the metaverse space completely presents user's states of mind which are captured from the brainwaves of the users. Furthermore the whole sceneries and presentations of the roles in the metaverse space are adjustable with the changes of the users. It can also express user's personalities. Interaction modes between the users and visitors entering into the metaverse space of the user could be analyzed based on the method disclosed in the present invention.

Abstract: A spine and ache relation database stores the relations of aches of different portions of human body and the related vertebrae. In the test, the brainwave comparison module compares the brainwaves from the first helmet worn by the tested persons and the second helmet worn by the test apply person so as to determine whether the brainwaves from the first helmet and the second helmet are synchronous. The test applying person contacts the tested person and moreover, the test applying person thinks an aspect of one of the vertebrae continuously and repeatedly in a time period, in that the test apply person may emits voice about the aspect of the vertebrae or only think in the brain silently. The brainwave comparison module compares all the aspects of the selected vertebrae so as to determine which aspects of these vertebrae are displaced or shifted. A method using this system is provided.
