Hi Tom,
Your comment got me thinking. Affordance indicates a sensory cue. Visual is one of the five senses.
In this strip, the dartboard has the affordance of ‘being hit’. This example of affordance happens to be a visual one.
That’s how I see it. Let me know what you think. My company conducted research on Affordances in elearning. If you are interested, read the article at http://elearning.kern-comm.com/?p=7
