3. Types of VR Devices
 Tethered Headset
Requires a wired connection to an external system with strong computational power
Must run at least 90fps for immersion
Expensive and heavier
Rotational (head), positional, motion, eye and room scale tracking
 Mobile Headset
Requires a wireless connection to a VR compatible mobile device
Must run at least 60fps to minimise nausea and motion sickness
Cheaper and lighter without the mobile device slotted in
Only rotational (head) and/or positional tracking
