As I mentioned in a previous post, I used my iPad during the Spring 2013 semester as a control center for displaying images, video, and (don't judge me) bullet points. In my imagination, this made me the coolest professor on the planet. I oozed awesome with every gesture and swipe of the iPad. My students thought I was a dork.
I don't know if that word actually came to mind, but the vibe was definitely tangible in the room. My protocol for projecting the iPad display was pretty reliable, but I was using AirServer over a Bluetooth connection that could only handle a small amount of data at once. There was often a delay between what I was doing on the iPad and what the students were seeing, and sometimes the connection would freeze altogether. This connection would also not handle video or any type of animation. Personally, I did not see this as a big deal, but my students did and said as much on their course evaluations.
This prompted me to re-think how I was going to use my iPad as a portable lectern, or if I was going to do this at all next semester. I revisited a few different options I had explored before, and nothing seemed to do what I wanted. That is, of course, until I happened to read the SlideShark blog. I had used this app a few times already for presenting slides, and I liked it quite a bit. I was able to monitor my presentation with a timer, see my presentation notes, and quite importantly, preserve any animations I had embedded in the slides. The app also handles embedded video pretty smoothly without the need to include the video file somewhere on your device. Everything is computed in the cloud and is downloaded to the mobile app.
Until recently, I still had to mirror my iPad display onto my MacBook via AirPlay by way of AirServer in order to use SlideShark. Even though it was a step up from some other apps I was using, it still got hung up sometimes and would stop advancing the main points I was covering in the class meeting. Apparently this is quite exasperating to undergraduates (though they expect me to be "cool" with their "multi-tasking").
SlideShark has now added the Broadcast feature to it's app, which lets a presenter remotely control slides through the cloud from an iPad. This means I do not have to connect my device to my MacBook via AirServer. I just have to make sure my iPad and the computer connected to the projector are both online. Here is a brief rundown of the workflow:
- Upload the presentation to your SlideShark account
- Open the SlideShark app from your iPad
- Download the presentation to your device
- Open the presentation and click Broadcast
- Open a browser on the computer connected to the projector
- Go to: www.slideshark.com/meet/username
- Your slides will be remotely controlled with your iPad and displayed through this browser window. You can expect a 2-4 second delay between the device and the browser. When you stop to think about it, that is FREAKING AMAZING! 2-4 seconds?! Are you kidding me?!
Of course, this method is not perfect. You can't ...
- Show the iPad display. This will only show your slides. If you need to switch between apps, you will still need to use something like Reflector or AirServer.
- This option is not free. After June 15, when the trial period ends, the ability to Broadcast slides will set you back to the tune of $95 a year. That is not chump change in my household, but I think it will be worth the money if I use this tool as much as I think I'm going to.
- I have still had some problems getting videos to play. The FAQ section says that any format of video other than AVI or WMV will not play in-app. Since I'm a Mac user, this is a problem. I am still testing it out with .mov format, since that seems to be the .wmv equivalent on a Mac. You should also be prepared for a very lengthy upload time, depending on how many videos, and of what size, you include. Additionally, this will eat up your storage space if you upload too many large files with embedded video.
- You will encounter problems if you try to include active links to web pages. Since the slides are running within an app, the link will open a browser but it won't be visible through the Broadcast meeting in the browser. Oddly, hyperlinks within the document, such as Action Buttons, still work. This enables users to create non-linear presentations, if that's what they prefer to do. I rarely use this feature myself.
If you are interested in using your iPad as a mobile lectern for teaching, I would recommend testing this and other methods of remotely controlling your iPad in order to see what works best for you. If your school/workplace does not block AirServer over WiFi, this by far the best way to go. If that is not an option, SlideShark may be a pretty dependable workaround.
