<p>PowerPoint should make presentations easy, perhaps too easy in the minds of some audiences. But the reality for the person on the podium is often less relaxing. There is too much to go wrong. Cables go missing. Batteries die. And pieces of tech that are supposed to communicate with each other imitate sulky teenagers and refuse to talk.</p><p>Finnish startup Presefy has developed what sounds a very neat way of dealing with these problems using a smartphone, as Arctic Startup reports:</p><p>The way it works is pretty simple. You upload your presentation into Presefy, and when you're ready to present, you navigate to the presentation on your phone and select. You then have a URL you can display the slides on a projector or share the code with the audience so they can follow along on their devices.</p><p>The cool thing about booting it up on your phone is that you then can view and control the presentation from your device. The clicker devices you can buy for presentations are cool, but nearly everyone has a web-enabled phone these days, and its great to see the presentation on your phone's screen. As long as you have internet access, you can wander through the audience (because that's engaging) and still know where you are in your slide deck and move to the next slide.</p><p><a href="http://blogs.wsj.com/tech-europe/2013/03/26/presefy-simplifies-presentations-with-smartphone-control/">Keep reading...</a></p>
