X4.04.2Predictable control authority allocationdesignresearch

Fusion-weight allocation must be predictable rather than opaque

Aliases: authority allocation · assistance gain · adaptive shared control

What it is

Predictable control authority allocation makes the relative influence of human and machine follow understandable conditions. Weight may adapt to risk, confidence, or phase, but a person needs to know when correction strengthens, input passes through, and why identical commands differ.

Why it happens

Operators learn dynamics from input–output relationships. Opaque weight changes make that mapping non-stationary, prompting exaggerated command, probing, or disengagement. Changes coupled to visible risk, boundaries, or confidence can be attributed to context.

Studying it

Fixed, rule-based adaptive, and opaque adaptive weights can vary change rate and cueing while measuring output prediction, compensation, conflict, transfer, and agency. Actual weight and rationale need logging. Mean performance can hide rare unpredictable overrides.

Where it stops holding

Exact formulas need not be exposed; behavioural boundaries and cause may suffice. Emergency constraints can immediately dominate but need explanation. Predictable does not mean fully user-configurable when safety is at stake.

Applying it

  • Bind weight changes to few visible conditions and show the direction of current human/machine influence.
  • Preview major override through haptic, visual, or resistance cue and retain the cause afterward.
  • Test output prediction across contexts, monitoring overcompensation, repeated command, and abandonment.
