Neurocognitive Assessment in Virtual Reality Through Behavioral Response Analysis.

Area of Science:

• Neuroscience
• Medical Technology
• Human Computer Interaction

Background:

• Early detection of neurocognitive disorders is vital for patient prognosis.
• Motor and visual dysfunctions are early indicators of neurocognitive decline.
• Current assessment tools lack objectivity and generalizability.

Purpose of the Study:

• To develop a novel, unbiased tool for assessing neurocognitive function.
• To evaluate visual perception, motor skills, attention, and memory objectively.
• To provide a platform for comparing different neurocognitive disorders.

Main Methods:

• Utilized virtual reality (VR) with integrated eye tracking and motion analysis.
• Developed a prototype system simulating a baseball game scenario in VR.
• Captured full-body motion and analyzed responses to visual stimuli in a controlled environment.

Main Results:

• Preliminary tests with 20 healthy individuals showed the system's ability to assess balance, memory, attention, and visual reaction time.
• The VR platform demonstrated objective assessment of neurocognitive constructs impacting visual and motor capabilities.
• The system enables neutral and objective data collection based on controlled stimuli.

Conclusions:

• The proposed VR system offers a novel, objective method for neurocognitive function assessment.
• This technology can aid in the early detection and diagnosis of neurocognitive disorders.
• The platform facilitates standardized comparisons across various neurocognitive conditions.
