Google's presentation app has a new Q&A feature that lets audience members submit questions and vote on them.
When giving presentations, most speakers provide an opportunity for questions from the audience. The problem is that when they call on a questioner, there's no way of gauging the general relevance of a question in advance.
But that's changed with the arrival of a new feature in Google Slides.
Slides Q&A – which is available in all new Slides presentations – allows audience members to submit their questions from their phones, tablets or computers. This can encourage questions from people who are normally reluctant to speak in front of a crowd.
But the interesting part is that the audience can vote on each others' questions, allowing the speaker to prioritise issues that are of concern or interest to more people.
Other recent improvements to Slides include presenting to a Google Hangout from the Slides app for iPhone and iPad, and the inclusion of a 'laser pointer' to draw attention to particular parts of a slide when using Slides on a computer.
You can find out more about Slides Q&A at the Google Docs Blog or by watching the following Google video.
