| [* black] Dangling off the headset's smoothly curved sides, a mysterious cube. What is it? | |
| [* black] Survey says: EM sensor coils for [https://en.wikipedia.org/wiki/Positional_tracking#Magnetic_Tracking|tracking the position|new_window=true] of the totem. | |
| [* icon_note] Magnetic tracking relies on those three copper coils forming three perpendicular magnetic fields. Then the fields' intensity in relation to the totem is measured to determine the position and orientation of the totem relative to the headset. | |
| - | [* black] Suspect it receives three orthogonal timed multiplexed magnetic fields. |
| - | [* black] The copper Faraday shield sprayed onto the plastic is likely to protect the coils from RF while allowing the magnetic field to pass through. |
| - | [* black] The somewhat awkward integration into the headset suggests this may have been a last-minute addition. (It's actually a pretty good position. Positioning has to be pretty particular in order for it to work: away from all metal & EM generating sources, and no electronic obstructions between it and the controller.-Arthur) |
