I'm just thinking out loud here. One approach is to replace the green Try It Now button with an image of the Prof, under which you say "Hi. I'm the Prof. What's your name?", following by text field and green button. Then experiment with what the green button says.
It would be interesting to see if a vague 'what's your name' approach, rather than a specific direction with a stated outcome, wins in a split-test.
Nice idea - we would need to connect the headline explaining the programme with the Prof more clearly, but that's pretty easy. Will work it up, thanks!
