DISQUS

Laura Bergells · 1 year ago

Heh. I received a laser pointer as trade show swag over 10 years ago. I never used it on stage myself -- but for the first year or so, it was a dandy toy for pestering my tropical fish.

I kept the toy in my kit for a few years, too -- but whenever presenters asked to use it, I discouraged the practice.

"Let's see how you rehearse without it," became a pat phrase. After rehearsal, I would usually offer positive reinforcement for their non-laser performance.

My laser pointer has been in my kitchen junk drawer for quite a while now...

@Laura Bergells: I agree. In most cases, it's best to reserve the laser pointer for exercising the cat once you get home. There's one major exception in my line of work. When one of our speakers is showing a graph, especially one that's displaying the data in a nonstandard way, we suggest to them that they take a moment or two to orient the audience to the graph before explaining what the data mean. Basically reviewing what's on each axis, the significance of the particular scale of each axis, things like that.

Laser pointers banned after attacks Mon Apr 21, 12:11 PM ET

SYDNEY (Reuters) - A major Australian state has banned laser pointers after a spate of incidents in which aircraft pilots have been temporarily blinded, the government said on Monday.

High-powered hand lasers, including so-called "star pointers" used by astronomers, would be listed as prohibited weapons in New South Wales state with jail terms of up to 14 years for anyone carrying them without a permit.

"It is a gutless and cowardly act that could result in an horrific outcome. It only takes a fraction of a second for a pilot to become temporarily blinded and that could have catastrophic consequences," said state Premier Morris Iemma.

Several pilots have recently reported high-intensity lasers being shone into their cockpits during take-offs and landings, and police recently enlisted intelligence agencies to help combat what papers called "laser lunatics."

The latest incident occurred over Sydney's south at the weekend when an ambulance helicopter was hit by a green beam.

The ban will build on planned national importation controls announce by the federal government earlier this month, treating laser pointers like firearms.

"It's destructive, dangerous behavior which needs a coordinated response across Australia," said Home Affairs Minister Bob Debus.

@Mike: Thanks Mike. People have trouble hitting the spot they want to highlight on a screen thirty feet away from the podium they're standing behind. How on earth is anyone aiming a handheld presentation laser pointer at a smaller, much less stationary target with anywhere near enough accuracy to be dangerous?

My take on laser pointers is that they don't add much. I much prefer to see a presenter get 'physical' with the slide - walk over to it, into the beam if necessary and show us the axes as they're explaining it. The presentation by Hans Rosling at TED is a great example - http://www.ted.com/index.php/talks/view/id/92.

The only reasons I can see for having one is if the screen is too far away from the presenter to walk into, or if the presenter has a physical disability and can't walk to the screen.

@Olivia: I agree with you that, in most cases, laser pointers don't add much. Great example of an alternate strategy. I also like the way Rosling uses the arrow cursor as a pointer. He's an amazing presenter.

Unfortunately, most of the presentations I support now take place in a very formal, regulatory environment. There are no lapel microphones. There is a lectern and, during the main presentation, the presenter is expected to be standing behind it. During the Q&A; period, if you're not behind the lectern, you're most likely at a microphone by the "bullpen" which is even further from the screen.

Once again, it comes down to determining what tools and techniques best help the speakers make the points they need to make and tell the stories they need to tell.

Laser pointers can become dangerous. They are like every other dangerous weapon. They are not necessarily harmful on their own by they can be if used by morons.

This is seldom, if ever, mentioned in presentation specific blogs. In the world of computer-related training we often have to display screens of source code. Source code doesn't lend itself to nice, pretty, slides. In fact, many times it is better to use an editor to display it than it is to use PowerPoint.

I have seen laser pointers used effectively while the speaker discussed source code. Laser pointers are sometime, not often, useful in allowing an audience member to point out something on screen that they would like clarification on (source code, again).

My current presentation remote has a laser pointer built-in. I find it useful for checking to see if the batteries are dead but that is about all I use it for.

Lee Potts · 1 year ago

Thanks for stopping by and commenting Jeff. Just like any tool it has to be used the right way at the right time. That bit about using the laser pointer to check your batteries is the best line I've heard in a while. Think I'll make it comment of the week.

Anyone know where you can buy those flashlights that make a big (6") arrow on the screen? We had them in graduate school before laser pointers, and they were wonderful. They were heavy enough to ensure that the pointer didn't jump around, and also heavy enough to discourage overuse (e.g., highlighting every word on the slide). I really miss them. Laser pointers, especially frickin' laser pointers, are only good for entertaining cats. Really good, I might add.

I also agree strongly with Jeff about audience participation. I have a small fleet of them for that usage. And with Olivia about who should be allowed to use them. In almost all cases, it is far, far better to just walk over to the projected slide and interact with it, without silly props.

Lee Potts · 1 year ago

Hi Colin. I associate those big arrow flashlight with trips to the planetarium when I was in grade school but I can't remember ever actually seeing them for sale anywhere. Sounds like they would really do the trick, at least if you were standing at a decent angle in relationship to the screen. That's actually the same concern I have with walking over to the screen. When we do our FDA presentations, we're expected to present from the lectern which can sometimes be a good distance away from where the screen is and going back and forth would be pretty disruptive. Thanks for stopping by and taking the time to comment.

When I attend conferences nobody uses a laser pointer anymore, it's so 80's. My wife, an elementary school teacher, recently had to do a presentation to parents on proper writing examples in preperation for a big state test. What we did for her presentation was to highlight each section of text she was going to discuss with what looked like yellow highlighter in Photoshop. She just pushed next slide on her remote and it automatically highlighted her next point.

Their is no reason for laser pointers anymore. Just prepare your powerpoint in a way to do the highlighting for you. You can also have your powerpoint slide have a circle around part of the photo or anything else.

Sorry Socal but I think you're overgeneralizing here. There are situations in which a laser pointer is very necessary. Situations where it's not practical to highlight particular parts of a slide in advance of the presentation. For example, say you're presenting the findings from several studies to a group of scientists as part of the process of getting a new drug approved for sale. Your main presentation will only contain a small percentage of the total number of slides you will be preparing. You may have hundreds, perhaps thousands, of backup slides -- most of which will never be shown, but that need to be included in case they are needed to answer a question. Not only do you not know ahead of time which of these slides you're going to use, you have no idea which piece of data from which table or graph you will want to draw the audience's attention to. It will all depend on the question and how it's asked.

I'm would also be concerned about using Photoshop to highlight the text on your slides. When you add the highlighting in Photoshop, aren't you turning the text into an image which you put into the slide? Doesn't this make the PowerPoint file really big?

Socal · 1 year ago

OK, I've never been a doctor presenting on a new drug. Obviously their are times I have not thought of that a laser pointer still works. I was a little harsh when I said laser pointers are dead.

In regards to the size of the image for Powerpoint, no, it doesn't make the file really big. Especially if it's just black and white text you can save it as a compressed 8 color gif file and it takes up about 18KB for a full size image of 1 page of text.

In fact, in the marketing industry people load up video files on their thumbnail drive and include them in their Powerpoint presentation often now. So size seems to not be much of a problem like it used to be in the old days.

On a good note, I did like the story you shared about blinding people in the eye. I always like the presenters that are trigger happy and seem to advance 3 slides every time instead of just 1. Your blog definitely made me laugh. :-) Keep up the good work.

Lee Potts · 1 year ago

Hi Socal,

Don't get me wrong, I agree that in most typical situations, the laser pointer causes more problems than it solves. Especially when your slides adhere to the minimalistic aesthetic that's so fashionable these days.

I think I'm more worried about increasing the size of the PowerPoint due to embedded graphics not just the size of the files you need to carry around. I've had stability problems with large PPT files containing a lot of graphics.

Glad you like my blog and that the stories ring true to you. Hope you continue to enjoy it.
