We have developed immersive daily-life-based VR scenarios specifically designed for elderly individuals with mild cognitive impairment (MCI). By incorporating clinically validated evaluation indicators and algorithms, our program enhances the effectiveness of cognitive training and provides a comfortable training environment for users. Additionally, a user information management platform enables personalized programs by identifying cognitive domains for each user.
Step 1: Cognitive Function Assessment
Using motion-recognition-based cognitive evaluation methods, we assess the user’s cognitive state through six individual test domains: visual perception, visuomotor coordination, constancy, spatial perception, situational awareness, and spatial relations.
Step 2: Activities of Daily Living (ADL) Evaluation
Users perform six evaluation tasks that simulate real-life social challenges commonly faced by the elderly. These tasks combine spatial and visual elements in a storytelling format designed to stimulate memory.
Step 3: Cognitive Rehabilitation Training
Based on the cognitive abilities identified in Steps 1 and 2, users undergo functional game-based cognitive rehabilitation training. The training targets specific areas of deficiency and allows for content selection, repetition, and focused practice.
Step 4: Learning Management Platform
The system collects and visualizes data from all assessment and training stages. It provides a clear overview of improved cognitive domains and the user's overall cognitive status, and offers personalized training recommendations for continuous cognitive enhancement.

The VR Physical Check-up Program is a medically validated and engaging healthcare solution that allows users to perform six different physical assessments in a virtual environment, as if playing a game. It combines medical accuracy, interactivity, and professionalism to provide a functional and immersive experience.
Step 1: Color Vision Test
Users identify numbers within images based on the Ishihara color test plates, assessing color perception.
Step 2: Memory Test
A short-term memory test where users match pairs in a puzzle format to evaluate memory retention.
Step 3: Hearing Test
A pure-tone audiometry test using electronically generated tones across various frequencies to measure hearing ability.
Step 4: Reaction Speed Test
Users quickly respond to randomly appearing lights by turning them back on, measuring visual and motor reaction time.
Step 5: Instant Perception Test
Users must hit targets flying in from random directions while avoiding obstacles by moving in the opposite direction, testing perception and coordination.
Step 6: Brain Activity Test
In a virtual environment, users guess the correct answer by observing objects and their initial consonants, evaluating problem-solving and cognitive skills.
Comprehensive Evaluation
After completing all six tests, the program calculates a total score to determine the user's "physical age," providing tailored health insights ranging from teenage to senior age groups.
