New Logitech Dark Field Mice Operate On Glass

CmdrTaco posted about 5 years ago | from the data-goes-in-here dept.

Input Devices 225

Slatterz writes "Logitech has introduced new mice that use two lasers rather than one to work on a variety of previously unusable surfaces. The first laser picks out imperfections in the surface of a tabletop while the second laser focuses on microscopic imperfections highlighted and uses those to direct the cursor. The technique, dubbed dark field microscopy, allows mice to be used on almost any surface, including glass (as long as it is more than 4mm thick)."

Dark Field Microscopy... (4, Interesting)

Re:Dark Field Microscopy... (5, Informative)

Dachannien (617929) | about 5 years ago | (#29152559)

In case anyone cares, "dark field" refers to an imaging technique which uses a light beam to illuminate a surface, but positions the sensor such that specular reflections (i.e., direct reflections which occur when light strikes a fairly smooth surface) are not picked up by the sensor. Instead, scattered (diffuse) reflections are picked up by the sensor, which highlights bumps and nicks in the surface.

Compare this to "bright field" which refers to a technique where the specular reflection is received directly by the image sensor. The specular reflection is typically much brighter than any diffuse components which also happen to strike the sensor, so a simple threshold is able to filter out the diffuse components.

Both techniques are used in, e.g., inspection of objects for defects, such as integrated circuits and masks, PCB soldering, etc.

deglr6328 (150198) | about 5 years ago | (#29152649)

also, it doesn't have shit to do with using "two lasers", the story writer at PC Authority is just retarded. In addition, if I might editorialize, is this really necessary? How hard is it to just grab a piece of paper or something and use that, or, GASP, use a mousepad! What's Logitech going to come out with next, a raman scattering microscopy, mid-infrared quantum cascade utilizing wireless mouse, for those times when you simply must do your mousing on an atomically pure, sub-angstrom microroughness telescope mirror in a class 1 cleanroom? cmon now.

Re:Dark Field Microscopy... (5, Insightful)

Dahamma (304068) | about 5 years ago | (#29152951)

Well, they do use two lasers. No, it doesn't REQUIRE two for technique of "dark microscopy" itself, and the article's description of their use doesn't make much sense at all... it's just to provide more than one angle to bounce off any imperfections.

Still, I don't see anything wrong with a mouse that tracks so well it will work on glass. It's not like it is designed for glass ONLY, it just means it will work even better on any surface you have. It's just the stupid blogs and reviews that have to go rub it on everry glass surface they can find - Logitech's marketing just says "Experience extreme accuracy and flawless tracking on virtually all surfaces."

acidream (785987) | about 5 years ago | (#29153287)

I've got one of those vibrating "power" razors, and its actually one of the best razors i've ever used, too bad the damn blades are 17 dollars a box.

But Five blades really is better. (4, Insightful)

tjstork (137384) | about 5 years ago | (#29153113)

First off I wouldn't give the Onion too much credit for "foretelling the blade count war", because, every teenager and pre-teen has been making 22 blade razor jokes probably since they first made twin blade razors. It's not a big deal

Secondly, five bladed razors are better. The five blade Gilette Fusion is a wonderful razor. Having to use an old twin blade compared to the fusion is just terrible. In fact, my wife routinely steals mine (and a fresh blade), in order to do her legs. Lady's twin blade razors in cute little pink and white packages do not work as well as a good old five blade ultra sharp kick butt razor.

Bottom line is, if Gillette's research arm comes up with diamond tipped blades, or some sort of a ten bladed razor, then they've got my interest. Paying extra for a razor may seem like a waste to some, but after twenty or thirty years of shaving with crappy razors, those few extra bucks are money well spent. A good razor is worth it, and honestly, I could see a good mouse being worth it too.

how's this compare to BlueTrack? (5, Interesting)

Trepidity (597) | about 5 years ago | (#29152411)

This is pretty much the selling point for Microsoft's BlueTrack [microsoft.com] (video at Amazon [amazon.com] ) as well. Theirs appears to be based on a blue LED and some optics picking up / processing the scattering, rather than dual lasers, but since they're more or less aimed at the same problem and claim similar success, I'd be curious how they compare.

Re:how's this compare to BlueTrack? (2, Informative)

Trepidity (597) | about 5 years ago | (#29152475)

Replying to my own post, it looks like BlueTrack specifically disclaims working on glass. However, a different mouse [royche.co.kr] already claimed to work on glass [gizmodo.com] two years ago.

I suppose what I most want is a bit of an overview of what current mouse tech we have and what they're good for.

And with my trackball, I can do all of the above, and not have to move the mouse around physically to do it. Plus, because the ball is a fixed entity, the lasers/pickups can be optimized for it (and it can be designed for most efficiency too). So not only do I not have to move the damned thing, meaning that I've got that much more desk space available for notes and such, it's much more accurate.

Or perhaps we could stop with the pissing match and saying how mine's better than yours, and agree that it's a question of personal preference, and that people will choose what they want to choose?

Re:Umm... (1)

raving griff (1157645) | about 5 years ago | (#29152979)

Regardless of glass's age, it has only become a mainstream feature of desks in the past five to ten years. I would be willing to bet that five years ago, the fraction of people using a glass computer desk was a tiny minority. Aside from that, mousepads were still in wide circulation, as roller ball mice were still somewhat mainstream. These two facts combined mean that very few people would run into a problem with being able to use their mouse with a glass desk.

All of them. 4mm is the thinnest glass you will find in a house - e.g. windows, cabinet doors.
Coffee tables around here use 5mm, and larger tables are thicker.

That said, if and when Toyota or anybody else figures out how to port their brain-controlled wheelchair tech [geek.com] to the PC, the mouse may indeed become one of those things your future grandkids will see in photos and ask, "Did you really ever use one of those things?!

For all the things they've been able to get mice to track on, it still sucks to move a mouse on anything other than an engineered mousing surface. This new sensor may be a good feature for notebook mice that will be used on who-knows-what, but buying a premium gaming mouse for it's ability to track on crappy surfaces makes about as much sense as buying a Formula One car for its off-road handling.

And if anyone says "but it's better!": Today's well-made mice track fantastically well on a proper surface. They're already, for practical purposes, perfect. Yes, admittedly, there are people whose Logitech or Microsoft mice track poorly. But those people fall into two groups: (a) those who aren't using a pad at all, and (b) those who are using a horrible made-when-men-were-men-and-mice-had-balls pad they had lying around. Logitech and Microsoft would be better off just throwing in a proper mouse pad—and there are some excellent, relatively cheap cloth pads—than endlessly making slightly better sensors just so that people's cursors jump a bit less while they're scraping their mice back and forth on horrible surfaces.

(And if Microsoft and Logitech had half as much innovation in materials as they do in optics, their mice would move like air hockey pucks by now.)

What is wrong with you people complaining about logitech improving their product? I don't get it. My logitech mouse works on most of the surfaces I've tried it on, but not everything. Would I like it to work everywhere? It would be nice. I can't imagine why anyone would be opposed to that.

Also, no I don't use a mouse pad and I don't want to need one. Talk about pointless.

His point was this mouse is aimed to gamers for uber precision. But the feature is useless to gamers buying this mouse since they already have 50$ mousepads and do not need to use it on glass... What he is missing is that it is about the technology trickling down to everyday mice which will be usefull in the future even if not for the market they are targeting atm the tech is valuable.

Dark field mice are supposed to be a top secret, covert operation. How did you guys get wind of this?

My mouse will work with Windows?

Finally!

Can anyone help me? (1)

I'm jonesing for a new overpriced mouse that works on glass instead of my perfectly good $25.00 mouse that works just fine on my wooden desk.

Very good... (0)

...and it would be even better if they throw in a glossy red mousepad absolutely free. :)

$100 (3, Insightful)

Not surprisingly, the mouse costs a lot more than I'd be willing to pay. My 3-button, scroll-wheel USB Intellimouse Explorer 3 is close to celebrating it's 10th birthday, and is still going strong, and still feels to me like the best mouse I've ever used. Microsoft sure knew how to put their name on quality hardware back then.

Oops, forgot to mention I paid something like $7 for it, too, back when pricewatch.com was actually good.

I paid that 5 years ago for my Logitech MX laser cordless and it's the best mouse I have ever had. works great, feels better than anything else and still holds a charge for 4 days straight. I've worn finger patterns into the paint. Dont knock a high end mouse till you try one.

4mm Glass surface (2, Insightful)

Psychotic_Wrath (693928) | about 5 years ago | (#29153281)

I would hate to be the one using a mouse on a glass surface less than 4mm thick. It would probably break very easy. Some specs are kind of useless. Like linux supporting thousands of processors hehe.

I hope it does not reduce the number of plain old LED optical mice out there because those are a GREAT source for machine vision for robotics. the basic 32X32 pixel cameras in a mouse works GREAT for a small robot for machine vision.

I even have an arduino bot using one to avoid objects.
