Embodiment 1
[0048] This embodiment provides a spatial cognition rehabilitation training system based on virtual reality and eye tracking, including:
[0049] A virtual reality device, which includes a situational display component for displaying a virtual reality scene and a training task situation;
[0050] The infrared eye-tracking component is used to obtain the eye-movement data of the trainee in the process of completing the task according to the training task requirements in real time, and transmit it to the data analysis module;
[0051] The data analysis module is used to analyze the eye movement indicators of the trainee when completing the situational task according to the data obtained by the eye movement tracking component, evaluate the visual space processing characteristics of the testee, and transmit the results to the eye movement guidance cognitive training module ;
[0052] The eye movement guidance cognitive training module is used for invoking different eye movement p...
Embodiment 2
[0064] Based on the above-mentioned rehabilitation training system, this embodiment provides a spatial cognition rehabilitation training method based on virtual reality and eye tracking, including the following steps:
[0065] Step 1: receiving the user's selection of the virtual reality scene and selecting the training task scene;
[0066] Step 2: display the virtual reality scene and the training task, and start the eye tracking component;
[0067] Step 3: collect the trainer's eye movement indicators during the process of completing the task according to the current training task requirements;
[0068] Step 4: Analyze and process based on the eye movement index and the optimal completion result of the current training task to obtain the training result. If the training result is lower than expected, call the eye movement guidance cognitive training module and enter step 5. Otherwise, proceed to next training task;
[0069] Step 5: The eye movement guidance cognitive train...

Abstract
The invention discloses a spatial cognition rehabilitation training system based on virtual reality and eye tracking. The system comprises a virtual reality device. The virtual reality device comprises a scene display assembly which is used for displaying a virtual reality scene and a training task scene, an infrared eye tracking assembly which obtains eye movement data in real time when a trainee completes the task according to training task requirements and transmits the eye movement data to a data analyzing module; a data analyzing module which analyzes eye movement indexes when the trainee completes the scene task according to the data obtained by the eye tracking assembly, evaluates the visual space processing characteristics of the trainee, and transmits the result to an eye movement guiding cognition training module, and the eye movement guiding cognition training module which calls different eye movement prompting modes for guiding machining according to the visual space processing characteristics. The spatial cognition training is conducted through the virtual reality scene, guiding processing is conducted in a targeted mode, and the method has more ecology, effectiveness and operability compared with the prior art.
Description
technical field [0001] The invention relates to the field of virtual reality, in particular to a spatial cognition rehabilitation training system and method based on virtual reality and eye tracking. Background technique [0002] Spatial cognition is an important component of intelligence and plays an important role in many abilities in daily life. The visual-spatial impairment caused by brain injury and brain disease directly affects the rehabilitation effect, daily life ability and social adaptability of the trainee. At present, there is a lack of systematic training specifically for spatial ability impairment in clinical practice. Spatial ability training partially embedded in the cognitive rehabilitation system is mainly two-dimensional spatial ability training, lacking training in real situations. Moreover, the main clinical manifestation of brain injury or brain disease is limb dysfunction, and the cognitive training system operated with the help of limb movement is ...
