Eye-Tracking Cognitive Rehabilitation System
Jizhi Medical’s eye-tracking cognitive rehabilitation system provides objective assessment and training capabilities for patients with cognitive impairments following neurological injuries. The platform uses proprietary gaze-tracking algorithms to measure attention, memory, and executive function through interactive visual tasks.
Product Overview
Cognitive rehabilitation has traditionally relied on subjective clinical observations and paper-based assessments that may lack sensitivity to subtle improvements or deficits. This system introduces quantitative measurement through precise eye-tracking technology, generating objective metrics from gaze patterns, fixation duration, and visual attention distribution.
The platform serves dual purposes as both a diagnostic tool for cognitive assessment and a therapeutic device for targeted cognitive training. By tracking where patients look, how long they fixate on targets, and how they respond to visual stimuli, the system creates detailed profiles of cognitive function that guide treatment planning.
Key Features
At 20 years of proprietary gaze-algorithm development, Jizhi Medical’s system quantifies attention, working memory, and executive function through infrared tracking rather than paper tests.
- Proprietary Eye-Tracking Algorithms: Advanced gaze analysis developed through 20 years of research in rehabilitation medicine and data interpretation
- Multi-Domain Assessment: Evaluates attention, working memory, processing speed, and executive function through distinct testing modules
- Quantitative Reporting: Generates objective metrics and visual reports showing cognitive performance patterns
- Adaptive Training Programs: Adjusts difficulty based on patient performance to maintain therapeutic challenge
- Progress Tracking: Longitudinal data storage enables visualization of cognitive recovery over time
- Non-Invasive Interface: Assessment and training occur through visual interaction without physical manipulation requirements

Clinical Applications
Stroke Rehabilitation: Patients recovering from cerebrovascular events often experience cognitive deficits alongside motor impairments. The system provides objective measurement of attention and processing speed changes throughout recovery.
Traumatic Brain Injury: Following head injuries of varying severity, cognitive assessment helps characterize impairment patterns and track recovery. Eye-tracking provides sensitive measurement even when verbal or motor responses are compromised.
Neurodegenerative Conditions: Early detection of cognitive changes in conditions affecting brain function benefits from objective, repeatable assessment methods that can detect subtle changes over time.
Attention Disorders: The system’s focus on visual attention and fixation patterns makes it applicable for evaluating and training attention-related deficits.
Assessment Methodology
The system employs validated cognitive testing paradigms adapted for eye-tracking measurement:
Visual Attention Tasks: Patients track moving targets or identify specific stimuli among distractors, with gaze patterns revealing attention allocation and disengagement capabilities.
Working Memory Modules: Sequential visual presentations test retention and recall, with eye movements indicating memory search patterns.
Executive Function Exercises: Tasks requiring inhibition, task-switching, or planning reveal higher-order cognitive capabilities through characteristic gaze behaviors.
Each assessment module generates quantitative scores that can be compared against normative data and tracked across sessions to monitor rehabilitation progress.

Frequently Asked Questions
What conditions can be assessed with this system?
The eye-tracking cognitive system is designed for patients with cognitive impairments from stroke, traumatic brain injury, neurodegenerative conditions, and attention disorders. It assesses multiple cognitive domains including attention, memory, processing speed, and executive function.
How does eye-tracking measure cognitive function?
Eye movements reflect underlying cognitive processes. Where people look, how long they fixate, and how quickly they shift attention all provide measurable indicators of cognitive function. The system uses proprietary algorithms to analyze these gaze patterns and generate objective cognitive assessments.
Can this system be used for treatment or only assessment?
The system serves both diagnostic and therapeutic purposes. Beyond assessment, it provides adaptive training programs that exercise cognitive functions through progressively challenging visual tasks, with the goal of promoting cognitive recovery through targeted practice.
