I got myself a new toy for my computer. This air mouse: http://www.logitech.com/index.cfm/mice_pointers/mice/devices/3443&cl=us,en (I found it cheaper than that site though, just picked that one because it's logitech's site and a logitech mouse...I'm not promoting any particular seller.) After sitting in the back of a lecture hall for about 2/3 of a course watching other lecturers struggle with the challenge of being tethered to a mouse and computer, I went on a quest to see if there was something that could untether me when it's time for me to give lectures (we record all of our lectures using something called Camtasia, and that requires using the mouse pointer rather than a laser pointer for the recording to show what we point to on the slides). I CANNOT stand being confined to the range of a mouse cord (the lecture halls don't even have wireless mice) while giving lectures, and I really like the feel of actually pointing at my slides...I think for teaching purposes, it helps direct the students' attention to the right place to follow an arm pointed in the right general direction to find where the arrow or dot on the other end is. I compared reviews on a couple of similar products, and opted for this one. I have been playing with it tonight, expecting it to take a lot of practice to get used to it. It's surprisingly simple and comfortable to use! I haven't even gotten around to installing the software yet (that adds some features, but I'm not sure if I really need those). The most fun I'm having so far is with the scroll "wheel" feature...there's no actual scroll wheel, but optical sensors...and sound effects. :rofl: A quick swipe of the thumb over the center of the mouse lets me fly down the page with a sound effect something like cards in the spokes of bicycle wheels, or the ticking of one of those wheels they spin at carnival games. (You can turn the sound off, but I don't want to.) A gentler stroke or sliding and tapping will get you more control over scrolling. Anyway, I thought I'd share my find, because this might be useful for other people giving presentations. When I get to test it out on a full screen presentation, I'll let you know how it goes. Meanwhile, others might have experience with this or other similar products who can give more feedback that will help others decide if this would be useful and which one(s) to try. And, it's just plain fun holding a mouse like a remote control while leaving my laptop sitting by my feet on the couch rather than in my lap. I tend to get a sore thumb using the trackpad, but hate sitting at a table with the laptop to use a regular mouse, so this also is seeming like a good solution for that. Have these been around a long time and this is the first I've discovered them, or am I actually one of the first kids on the block with a new toy for a change?
