Discovery of the day

[Alf W]

I have a luminous drinks mat on my desk at home and have just discovered that an optical mouse doesn't work on it when used as a mouse mat. How weird. Why's this then?

You need service pack 3 for this to work. It is a hardware/driver fault.

Or switch to Linux.

An optical mouse works by tracking the light reflection of the light produced by the mouse itself. The luminescence of the mat is probably drowning out the signal produced by the mouse so the reflection is lost in the general brightness that its' receptors are getting.


Sorry - if I'm right I apologise for being so brainy so early in the morning. If I'm wrong then I retract my apology.

your mouse is upside down

It's the photons, they've phucked it!

Quite possibly.

More likely.

Because the ambient temperature has fallen drastically today, you have inadvertently created a Bose–Einstein condensate cloud under your mouse. Unfortunately, the mouse mat atoms have collapsed into the lowest quantum state of the external potential, at which point what you are seeing is the results of quantum effects on a larger scale in action.

Have you plugged it in?

[Alf W]

It has been checked and double checked as I've got two optical mice on the go at the moment and neither work. One's a full size one and one's a mini laptop one. They're both Microsoft ones though so I might need to widen the sample.

It must be something to do with the light coming back drowning out the reflected light from the mouse. Have also tried the mice on the window and they don't work on glass with light coming through.

Feck me I'm bored today!

Now I know who stole my photon-slowing-device.
