I certainly can't find one in the stores in my town.
A quiet one would be nice too.

I can't tolerate the EMF's from the opticals/wireless.
In the meantime I have a PS/2 mouse with a USB adapter, but trying to improve on that.
TIA

Yes they do, at least any that you would find from the past 25+ years on a PC. In fact the first ball mouse made back in 1972 used optical sensors. The two wheels are actually shafts with disks on the ends inside the mouse body. The disks are optical encoding disks which have slits evenly spaced around the circumference. The optical sensors detect movement by watching for breaks in the light caused by the disks rotating.Finraziel wrote:Ball mice don't have optical sensors...
By "EMF" do you mean "electro-magnetic fields"? If so, how are these affecting you?NoiseFreeGuy wrote:I can't tolerate the EMF's from the opticals/wireless
As washu says, this sort of mechanism is standard in all ball mice as it is by far the most compact, simple way of counting a disk's rotations.Mr Evil wrote:Some did; I had a few myself in the past.

The above setup works just fine actually.Finraziel wrote: ...Why is using the ps2 mouse with an adapter a problem though? I've used those in the past without noticing any problems myself...

Perhaps you can tell me what the page/link is to the mouse?joe1215 wrote:

In my mind the non-optical mice doesn't exist, I'm wondering whether you mean such one,

He probably means that although there are a large number of people claiming to suffer from electrosensitivity, double-blind tests show every time that it's purely psychological.NoiseFreeGuy wrote:Could you please rephrase this so I can understand exactly what you are saying?qviri wrote:
Unfortunately, if someone is bothered by an infrared LED they are likely to have larger problems than computer mice.
Thanks Neil for this info.NeilBlanchard wrote:Optical sensors, by definition do not have anything to do with electromagnetic forces. Wireless mice use radio frequencies, which are quite different from electromagnetic forces.
A wired optical tracking mouse would seem to be the solution to totally avoid EMF.
Rather than second guess what someone else means, I will wait until he speaks for himself and then reply to him.Mr Evil wrote: He probably means that although there are a large number of people claiming to suffer from electrosensitivity, double-blind tests show every time that it's purely psychological.
I am not trying to insult you, but no you can't. *NO ONE* has ever been able to detect such things in a double blind test. You think you can and have a reaction when they are around, but it's all in your head. If you can setup a real double blind test I highly suggest you do so, it would be very enlightening. A sighted A/B test is useless, it has to be truly double blind.NoiseFreeGuy wrote:Let me put this in perspective.
I can feel the emissions from basic power adapters. And they bug me big time.
Trackballs have optical sensors just like ball mice do.Plekto wrote:This is the best solution:
