Description

Technical Field

[0001] The present invention relates to the field of psychology and educational technology, and more specifically, to an Internet-based psychology and educational assessment device. Background Art

[0002] With the continuous development of psychology and education, psychological and educational assessments are increasingly used in personalized education, mental health assessment, career development guidance, etc. Traditional psychological and educational assessments usually rely on paper tests or simple digital platforms. The assessment content is relatively simple, and the assessment environment is limited, which cannot fully meet the personalized needs of different test subjects. In addition, existing assessment devices often lack automatic adjustment functions. During the assessment process, the equipment needs to be manually adjusted frequently to adapt to test subjects of different heights and perspectives, which increases the complexity and difficulty of the assessment.

[0003] Color selection is a common method of psychological assessment, which can help analyze the emotional preferences and personality characteristics of the subjects. However, the existing color card display method is relatively fixed and difficult to be flexibly applied in different assessment scenarios. Especially under different lighting conditions, the color presentation of the color card is easily disturbed, affecting the accuracy of the assessment results. At the same time, the color card components of existing assessment devices are mostly fixed in design and difficult to quickly replace or adjust, resulting in limited scalability of assessment content and applicability of the device. For this reason, we propose an Internet-based psychological and educational assessment device. Summary of the invention
