We have these long presentation in our organizations, where is becomes essential to keep track of time and speed of the presentations. We have started various measures such as displaying the the Slide Number and the percentage completion on each slide. Something like:
5 of 50 (10%)
The above detail is positioned in the page number placeholder via a macro. What I feel is the need to give a reminder at specific intervals to give an idea of how much time has elapsed vis-a-vis how many slides we have completed. What I require is something like this, three times during the presentation. At 25%, 50% and 75%. Powerpoint 2013 already shows the time elapsed in the Presenter view, however the same is not visible to the viewers. Is there any solution. The Reminder would pop-up, stay for 3s and then dis-appear. I will take care of the design etc of the pop-up, just need a way to make it appear at those specific intervals.
