Using Google Hangouts on Air for a Research Presentation

Using Google Hangouts on Air for a Research Presentation

Although Google Hangouts on Air launched in May 2012, I only recently discovered it when I chanced upon a colleague’s live lecture while scanning my Google+ feed. And what I saw, I liked. Google Hangouts on Air (or HOA for short) broadcasts what happens in a Google Hangout session. In that session, you can choose to have a conversation with people you invite, work on Google docs, or what I thought was the most promising, conduct a presentation via screenshare. The live session is streamed via YouTube and that live stream is automatically saved as a video whenthe broadcast ends.

Practice Makes Perfect

While the process sounds simple, I had to practise going through the process of setting up a HOA, broadcasting it and checking if the recording of the session matched what I imagined it to be – five times to be exact – before I was convinced I was sure of what to do at the actual presentation. Through the practice sessions, here are some of the pitfalls I encountered:

  • Entering a name for your HOA generates a YouTube link for the live session in standby mode. Hitting the broadcast button makes the video ‘live’. However, if you open the page for the YouTube live session and record at the same time, you will get two sets of audio being recorded. So after checking that the YouTube link has been created, close the browser or tab.
  • There are several options for screenshare – desktop and the various windows that are open. Although it may seem obvious to screenshare the particular application you are using for your presentation, that did not work for me – the slides did not appear to move as I clicked through them in presentation mode. What was more reliable was screensharing the desktop and then activating whichever application I wanted.
  • A mic is necessary for the best sound input. Otherwise the sound quality in the video sounds muffled.

HOA For Real This Time

The use of HOA at my presentation (of my research paper Understanding the Identity of One ELL in Singaporewent fairly smoothly but it was only after the whole process was completed did I realise the finer details of implementation. A few realisations as I watched the playback of my presentation:

  • The screenshare (using desktop) of my powerpoint presentation was exactly what I had on my desktop (presenter mode), but not on the projector screen (full screen mode). Using Microsoft Powerpoint 2013 meant that once the application detects a projector, it goes into presenter mode with the notes of the current slide and a preview of the subsequent slide show at the side of the screen. I didn’t like it but others thought it was cool. Note for future HOA: change the default presenter mode to full screen presentation.
  •  The mic I used was an arm attached to headphones and had a long wire so that I could move around with ease but stay connected to the laptop. While the long wire was helpful for movement, the awkward shape of an arm mic dangling from my neck resulted in inconsistent volume in the recording.
  • I recorded both the presentation and the Q&A which meant a 58 min recording. 58 min is an overwhelming duration for a YouTube video clip. In fact, some friends gave feedback that the video would stall halfway through. Not sure if it’s because the recording is too long or it’s a technical glitch. Either way, I intend to edit the video to include just the presentation portion which would last about 30 min.

More Tech Won’t Hurt

HOA aside, I was also experimenting with the use of Padlet during the presentation for audience members to post their questions, comments, etc. As it was a live audience, I guess few were inclined to post anything since there was going to be a Q&A session immediately after the presentation. A friend who was keen to try out Padlet did a little more than post comments. He posted a related link as well as uploaded a few photos of my presentation to my Padlet wall. I wasn’t expecting photos but this turned out to be a neat way of capturing moments of an event.

Conclusion

The best outcome of my presentation experiment was that the entire event was captured and archived. The YouTube video serves as a reference for me to reflect on how I could conduct a presentation more effectively, on how I could refine my thought process, and provides another avenue for me to share my research ideas with a broader audience. As long as HOA remains free, it will probably become the tool of choice among tech novices like myself to create (and archive) live presentations.
