Figure 5. The present affordance landscape of a bouldering wall (the MoonBoard).

Figure 5

(a) A climber attempts an example problem on the MoonBoard. (b-d) Example subcomponents of the probability surface: absolute landscape, relative landscape (unfiltered) and relative landscape (filtered to show only the available holds for this problem, with a sketch of a climber superimposed to show the posture). The black circles show the positions of the climbing holds in the example problem. The curved lines show the current positions of the hands and feet of the climber in Figure 1a, with the green curved line highlighting the limb whose landscape is shown. (e) The three subcomponents that are combined to form the probability surface of the climber’s left hand, which is the next to move; these are the absolute landscape (which is the same as figure 1b), the pose subcomponent, and the relative landscape of the left hand (which is the same as the top-left panel of figure 1c). (f) This is a naïve utility component: a distance gradient starting from the final hold of this MoonBoard problem. (g) The final Expected Value for the left hand, which is obtained by combining probability subcomponents of Figure 1e and the utility subcomponent of Figure 1f. See the main text for explanation.
