Promotional images in the article[edit]

Two or three item pictures in the article are of Microsoft products, which is very fishy IMO, it's very easy to find pictures of unmarked items.--Gilisa (talk) 19:07, 8 December 2010 (UTC)[reply]

Agreed, I think at least 2 other examples each from a different company would be good variety. Irazmus (talk) 11:20, 28 December 2010 (UTC)[reply]

Picture Trouble[edit]

There is a picture of an intellimouse that doesn't have a standard Wikipedia border and it's overlapping with some text. Could someone who knows how move it and give it the correct border, I'm afraid I'm quite new to wiki editing so I don't know how. Xeon63 (talk) 16:46, 14 December 2010 (UTC)[reply]

Picture in question removed due to seemingly being there for promotional reasons. Irazmus (talk) 11:18, 28 December 2010 (UTC)[reply]

Laser Mouse is IR???[edit]

If a laser mouse uses infra-red lasers, why can I see the red dot on my Logitech MX-1000 and other Logitech models, when carefully direct it into my eye? Surely that has to be wrong... — Preceding unsigned comment added by 77.231.249.167 (talk) 18:46, 20 June 2011 (UTC)[reply]

Yes, they are indeed IR. However, these aren't perfect lasers, nor are the LEDs which are also IR. They will emit into other wavelengths as well. For example, the ADNS-9800, the latest & greatest by Avago, emits in the range of 832-865nm, but I presume also leaks into the visible range as well (I don't actually own one of these, so I can't promise that it does). So the red light you see is where the laser is emitting in the 750nm and lower range, but it is primarily emitting in IR.

Still, do not ever point it directly at your eye, rather it's rated class 1 or not. Since most of the illumination is in IR, you wont see it, but it can still burn your retina. Daniel Santos (talk) 16:53, 25 March 2013 (UTC)[reply]

Useless trivia: Did you know that humans still maintain the ability to see in the "infra-red" range? If you wear goggles that filter visible light and allow your eyes time to adjust, you will be able to see significant differences in illumination in the upper IR range. Daniel Santos (talk) 17:01, 25 March 2013 (UTC)[reply]

The laser will not emit any significant radiation in the 'visible' spectrum, but you must remember that the eye does not have an abrupt cut-off between red and infra-red - the sensitivity just drops very steeply. 850nm is very-near-IR, and the high intensity of the laser means that it can be seen as a dull red. I wouldn't recommend looking at it either. Andrew / techmind.org 109.153.179.27 (talk) 23:28, 4 October 2014 (UTC)[reply]

Tiny speaker in mouse?[edit]

I removed the paragraph regarding the tiny speaker in modern mice being responsible for emitting the clicking sounds and it not being a mechanical sound. This is only true of 1 mouse in history that I can find reference to, the Apple Mighty Mouse, and is an irrelevant bit of trivia. 108.69.119.90 (talk) 18:47, 16 October 2011 (UTC)[reply]

Indeed it is only the Mighty Mouse that does that. Utterly useless design. 71.75.195.12 (talk) 21:12, 4 November 2011 (UTC)[reply]

Sun optical mice[edit]

From memory I remember sun mice being run over a rectangular metal grid. I think there were two different sizes of grid. Probably SS2/SS10 era at a guess.Djm-leighpark (talk) 21:20, 30 April 2019 (UTC) Ah .. described as hard mousepad in the Computer mouse article.[reply]
