Space cognitive ability intelligent evaluation system and method based on virtual reality

Abstract

The invention relates to the technical field of virtual reality, in particular to an intelligent spatial cognitive competence evaluation system and method based on virtual reality, and the system comprises a virtual reality module, a data recording module, a data processing module, an intelligent evaluation module and a database. The virtual reality module comprises a cognitive task unit and a master control interaction unit, provides a task login interface, an immersive virtual reality scene and a water maze cognitive test task, and realizes interaction between a user and a virtual reality scene; the data recording module is used for collecting and storing task performance data and behavior data of the user; the data processing module comprises data preprocessing and feature extraction; and the intelligent evaluation module automatically predicts a spatial cognitive ability score by using a machine learning regression model. According to the method, the virtual reality technology is applied to spatial cognitive ability research, automatic evaluation is realized by using a machine learning algorithm, the ecological effectiveness and convenience of evaluation are improved, and a new means is provided for application of spatial cognitive ability evaluation in multiple scenes.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to an intelligent evaluation system and method of spatial cognition ability based on virtual reality. Background technique [0002] Cognitive function refers to the ability of the human brain to process, store and extract information, that is, people’s ability to grasp the composition, performance, relationship with other objects, development motivation, development direction and basic laws of objective things, including memory, attention, Language, visual space, processing speed, etc. Spatial cognitive ability is an advanced cognitive function responsible for recording information about the environment and spatial orientation, and is closely related to visuospatial ability and memory ability in basic cognitive functions. Spatial cognition plays an important role in human daily life, such as finding routes, locating locations and targets, and using maps to navigate. It is a...

Problems solved by technology

[0003] Traditional methods often use scale checks to assess spatial cognition. Scale checks generally need to be carried out under the guidance of personnel with professional backgrounds, and are greatly affected by the test environment, and the evaluation time is relatively long

In addition to the inconvenience of personnel and environmental factors, the results provided by the scale inspection are usually limited, and some objective and accurate information is difficult to obtain

In recent years, computerized cognitive tests have also been widely used. Although automatic assessment can be achieved to a certain extent, the test tasks are limited by the form of presentation and still lack relevance to real-world scenarios, making it difficult to provide a good sense of environmental immersion. Little consideration is given to subjects' behavioral data
