fNIRS brain sensor enables adaptive VR training by measuring cognitive load
New study validates fNIRS to dynamically adjust VR task difficulty in real time.
Deep Dive
Key Points
- 36 participants wore full-head fNIRS caps during a VR shape assembly task to measure brain activity.
- Intrinsic mental workload activated dorsolateral prefrontal cortex, rostral prefrontal cortex, and left angular gyrus; extraneous load activated only right angular gyrus.
- fNIRS results closely matched NASA TLX subjective workload ratings, supporting real-time adaptivity in VR training.
Why It Matters
Real-time brain-based workload monitoring could make VR training far more effective by dynamically optimizing difficulty.
