Paul Smith's PowerPoint Pages Laser Pointers
Laser Pointers for PowerPoint Presentations a personal take, based on viewing thousands of presentations over the past 14 years
Never quite got the point. Most user have them because they always have, and are used with little thought. The user waves a tiny spot of light at high speed at an area on the screen. It’s clear to the user, because they know what they are pointing at, the audience is unsure. Unless used with great care the user makes more eye contact with the screen behind them than with the audience. There’s a risk also that if a microphone is not being worn that the user will be talking to the screen, not the audience.
If a pc or laptop is being used at a lectern the mouse pointer should be used. The presenter can maintain eye contact with the audience and glance at the PC for a moment when necessary.
If using presenter view, use a combination of Control+left Mouse click to enable an onscreen pointer. Yes, I know it’s designed to look like a laser pointer, but the point is much larger and can be controlled properly.
If you can’t stand still at the lectern and like to walk around with a slide changer (wireless presenter) get one that incorporates a mouse pointer. Remember that your audience is your priority. Don’t look behind you at the screen
Presentation venues are moving away in some cases from data projectors to large wall mounted monitors. These are light sources in their own right, not a reflective surface, so are not suitable for laser pointers (of Red, Green or any other colour) Higher powered lasers might damage the screen. If the screens are near to you why not consider using one of these digital pointers?
Bear in mind also that if your institution is using Lecture/Screen capture a laser pointer will not be recorded, So give some time to think about how you present
