Check this out… “a new feature in Google Slides: Slides Q&A. This update—rolling out globally today—helps speakers connect with their audience and collect real-time feedback. With a simple link displayed on a Slides presentation, audience members can submit questions from their phones, laptops, and tablets—and vote on those they want answered the most.
Slides Q&A makes it easy to interact with your audience—without having to worry about mics or moderators. Slides also helps you get your big ideas and stories on screen—without having to worry about wires or set up stress. Starting today, we’re improving this “Show up, don’t setup” experience in two ways:
You can now present your slides to a Hangout from your iPhone or iPad. So with just your phone or tablet and the Slides app, you can present to any screen using Chromecast, AirPlay or Hangouts.
And for those of you who like presenting from a computer, we’re introducing a new laser pointer on the web. Just in time for May the 4th (be with you).”
