I am currently designing a presentation that is supposed to run on an iPad that sales people take into busy, noisy small businesses to sell something to an owner who does not have time to listen to us.
Of course it has to be short. But we are pondering whether to go with lots-of-big-pictures-slides in 4 minutes, or a few condensed slides in 4 minutes. Big images are better to catch the attention of the owner, but constantly swiping through slides on an iPad might be awkward, and standing in the way of creating a human one-on-one interaction.
On balance, I think to go with the first, what do you think? Have you had experience with this?
