Step-by-step here is what he does:
1. Save his presentation to dropbox as a PDF. He also uses PPspliT, which is a PowerPoint add-in that splits animation effects into different slides.
2. Open the presentation on the iPad using a ten dollar app called Air Sketch, which lets you annotate PDF documents and images live. On the iPad you can an IP number that you can then copy into the browser window of a computer on the same local network and then annotatefrom the iPad in real time.
3. Start recording from the lectern PC using Tegrity.
All the processor and network intensive stuff happens on the lectern machine and the iPad just has to run the PDF viewer.
I downloaded Air Sketch and tried it myself. It worked great on an open network although I have heard of people running into firewall issues on certain campus networks.
Another PDF reader that Professor Walters referenced was GoodReader, which I didn’t try as Air Sketch worked fine.
Another app that I downloaded (for $5 this time) was Splashtop. With Splashtop you can do an install on your PC and log into your Google account and then run Splashtop on the iPad and log into the same Google account. Once you have done this, you can ‘see’ the PC from the iPad and take control. I was able to run Photoshop, enable VPN, and do anything else my PC can do, but from my iPad – well worth the five bucks!
Another thing that I want to do but have haven’t had success with yet, is to have my iPad view go directly to an overhead projector wirelessly. I have an iPad to VGA projector cable but to add wireless it looks like I will need to spend $100 on an Apple TV receiver and probably another $50 on an HDMI to VGA adapter for it if I want to use the airplay setup in classrooms with older equipment.
