More than one laser on a mouse?

Hey, I was just wondering whether there was a reason that on a mouse you only have one laser, when surely you could come up with a very accurate combination of hardware/software by creating an average of several lasers, and also removing any error when in comes to silly things such a getting a piece of dirt stuck in your mouse.

I could be being stupid, and it could be down to something like cost or its to complicated to do it simply, or that there's no need/demand for it due to the current technology already being good enough.

That was it really more general intrigue than anything, please let me know if I haven't been clear on something.

  1. there is no point to it.

    one laser is sufficient to track 2d motion. multiple lasers would be required only for 3d movement tracking.

    i've never had a piece of dirt cause an issue with optical or laser mice. stop using your mousepad as a plate.

    in general... dont fix what aint broke.
  2. There are have been mice with multiple sensors, here is one http://reviews.cnet.com/8301-21539_7-20070072-10391702.html

    http://en.wikipedia.org/wiki/Optical_mouse under "laser mice" is a blurb about Logtech making a dual laser mouse in 2009.
  3. well i have heard that sometimes mouses have 2 DIFFERENT laser sets, since there are some surfaces that works better with each of them, so it should only be using one at a time if the surface is a glasse that isn't working well on one, and works great on the other laser, it will use the other. nothing about that is confirmed but yes, it makes sense.
  4. Some Logitech mice have "Dark Field" which works very well on many surfaces that laser has a hard time with. The Logitech Performance MX mouse is an example.

    For example, "Dark Field" works very well on transparent glass, a pillow, even my ass.

    Razor has a new niche market "Hairy Mousing Surface"

    I love my MX mouse, but mostly due to the shape and balance/weight of it, does not feel like you are about to fling if off your desk when you move it around quickly.
  6. Yeah, I really like the MX's shape and weight... and it has a switch to turn off the mouse to extend the battery life. It could be slightly larger though.

    Gotta remember to buy another one when I see it for $50 - $60.
