I just attended a brief overview program of Bob Lane’s approach to creating interactive PowerPoint presentations. He calls it either Relational Presentations or Visual Interactivity. The idea is sort of like building a database of slides, and setting it all up so that any slide can be accessed from any point in the presentation. It’s a very cool concept, and he’s going to give a hands-on mini-workshop on the specific techniques for our STC chapter this Saturday. I’m really looking forward to it!
