If you’ve been in that spot where you suddenly need to do a Power Point Presentation, you can get less of the logistics worries and focus more on your actual content, by enabling your phone as a remote controlled Power Point clicker.
In this article, I’ll share with you a clever way of substituting the usual laser pointers and mouse clickers that come with most screen projectors.
PowerPoint Keynote Remote is a free app that is available for Android and iOS devices. It allows you to turn your phone or tablet into a remote Power Point clicker. With this, you worry less about when to signal for moving forward or back to the next slide, and you are free to move within any range from the screen projector receiver, and no longer have to worry about pointing the laser pointer to the limited view of the projector.
