Affordance
A concept proposed by ecological psychologist James J. Gibson, describing the action possibilities that an environment offers to a given agent. It is neither a purely objective environmental property nor a subjective intention, but a relation between the two. In computer vision and robotics, it is typically formalized as a mapping function from scene geometry and object categories to action candidates.

MAMHOI adopts a two-stage pipeline: in the first stage, a scene-conditioned model receives 3D environment input and predicts feasible interaction locations and manners, and in the second stage, an affordance-conditioned HOI model generates the corresponding human-object motion sequences.
The concept of affordance was first proposed by ecological psychologist James J. Gibson in 1979 to describe the action possibilities that an environment offers relative to a given agent.
In computer vision and robotics, affordance is usually formalized as a mapping function from scene geometry and object categories to action candidates, with common representations including affordance heatmaps, affordance pose distributions, or contact point distributions.
MAMHOI chooses affordance as the intermediate representation, leveraging its shareability across agents and tasks to separate "environment actability," which is unrelated to specific human motion, out of motion synthesis.
