What the System Knows

Position is not the whole pose

A tracking system typically describes an object with position in space and orientation—its facing direction. Together, these values form a pose. A headset pose informs the player’s view; controller poses inform held tools, aim, and interaction.

Systems may combine cameras, inertial sensors, or external references in different ways. The implementation varies, but the competition question is consistent: does the reported pose remain plausible and repeatable throughout the movement the game asks a player to make?

Reference frames matter

Coordinates have meaning only in relation to an origin and axes. A device-local frame, tracking-space frame, and game-world frame may all be involved. If the floor height or origin is inconsistent, every accurate measurement can still appear wrong in the arena.

Technicians should verify the reference point before comparing stations. Players can help by checking whether a stationary object stays still when they turn, crouch, and return to a known stance.

Coverage, drift and occlusion

Coverage describes where the system can observe the tracked object. A hand held behind the body, a controller blocked by another player, or a reflective surface may disrupt observations. Drift is a gradual change in estimated position or orientation; a sudden jump is a different symptom and may indicate a temporary loss or correction.

Use repeatable movements to separate ordinary variation from a persistent fault. Test forward reach, lateral reach, low stance, and a turn in the same order at each station. Record the location and symptom, not just “tracking feels off.”
