Interaction
What information is needed before approaching a surface or object?
Study the observations, uncertainties and operator review needed for a bounded task.
Representative scenes, documented limitations and comparisons against known references.
Recognition, distance estimation and deciding whether to approach are different outputs. A comparison should ask each method to provide the information it actually produces. Detection boxes, depth and thermal patterns should not be collapsed into one accuracy figure without a common decision criterion.
Scenes where the method returns nothing are part of the result. Documenting occlusion, reflection, timing and the reference uncertainty makes those cases useful. A reviewer should be able to distinguish a missing observation from a valid observation that advises against approaching.
