PowerPoint demo -- -- leaving behind the laser pointer

A very common lament about the host using the PPT is unfortunate trend is so much with the screen, rather than the audience.Uncomfortable is an audience watching a speaker's back, and he read his slide.Of course, this is a huge disconnect the speaker and the audience, this is the purpose that defeat in the first place.So why in the world who think the laser pointer will be a feasible, effective presentation tool?
For those of us who love toys and tools, the laser pointer is almost irresistible.The object you hold in your hands, modified, and then click a button, you can emit red light positioning bright on the screen in order to attract the audience's eye, a specific project.You can move them to round some important projects or do a prosperous at some point.It is interesting, its high-tech, it seems to be that the most advanced technology.
But, I'm sorry, let you down, but the device coordinates lovers, because all its high-tech appeal, also absolutely no recommended the use of.The reasons are as follows:
1.First of all, if your visual effect is good color contrast, which means there will be a dark background rich color (light) case, it is difficult to even see the red beam in the dark background.I have seen the presentation, the audience does not know the speaker even using a laser pointer, because they have never seen the light.
2.Secondly, the use of its essence -- had to direct laser screen -- to the speaker face and point to the screen.This means that her back was opened the audience talking to her screen, rather than the people in the room.Obviously, this is a big gap between the speaker and the audience.
3.There is a small problem, may occur if the speaker forgot to turn off the laser beam, while making the gesture, eventually throwing, red all over the room.
You can be a pointer.In addition to large conference room screen, the vast majority of the size of the screen, making it easy for your own reference visual speaker.By stepping back from the screen, the reference point, you are effectively guide the audience's attention, while maintaining your own pictures, let the objective gesture.
