🥽 VR Technology Fundamentals
Virtual reality involves immersive technology, spatial computing, and haptic feedback systems.
Field of View (FOV)
The angular extent of the visible environment:
FOV = 2 × arctan(d/2f)
Where d is the display width and f is the focal length of the lens.
Motion-to-Photon Latency
The time delay between head movement and display update:
Latency = Processing_Time + Rendering_Time + Display_Time
Where each component contributes to the total latency.
Presence Calculation
The sense of being in a virtual environment:
Presence = f(FOV, Resolution, Latency, Haptic_Feedback)
Where presence is a function of multiple VR parameters.
🥽 Key Insight: Virtual reality requires high-quality displays, low latency, and immersive interactions to create convincing virtual environments.
