Optical Mouse Saves Space in Cellphones

Chris writes "Researchers at Philips have integrated a space-saving optical mouse into a mobile phone for the first time. Dutch researchers at the Philips Center for Industrial Technology have developed a compact, optical interface for portable electronic equipment. The team says that its new input gadget can be easily integrated in cellphones, laptops and PDAs, providing an space-efficient alternative to a mechanical trackball or touch-pad for example. The device is made up of a low-power red laser diode and a detector placed beneath a lens. Light from the 650 nm laser is focused on an object, such as a fingertip, creating an external cavity. It is not necessary to touch the lens. A small portion of this light is then reflected back and mixes with the light within the internal laser cavity."

      So I'm thinking of a whole new product - take the cellphone optical mouse, add the mousephone and the Cymouse - "Cymouse knows the exact location of your head in a 3-D space. In the Cymouse world, we call this the 'direction'" - and you get a input device that uses lasers to create external cavities, monitors the position of your head, and lets you use the phone and get on the INTERNET at the same time! I'll be rich, damn you!

    When I first read the headline I was invisioning this optical sensor in the back of a phone and you'd move the phone around on a desk to move the pointer. Now that would be funny to watch in a restaurant.

    So I have a tooth cell phone, that has an optical laser pointing device, and built in cameras?

    shesh, I dont think anyone needs live feeds of me operating my laser controlled cell phone with my tongue all while making plans for which pubs we'll be visiting that evening. that's too 'geek' for me... but it would be hillarious!

    I want one that creates an INTERNAL cavity!

      well, mod the phone so that the lazer is at 65000 nm.

      I'll bet you might see an internal cavity then...

    "The demonstrators were sized some 15 x 10 x 8 mm^3," says Duijve.

    That's what, 1200 mm^27? I don't know about you, but I have problems with just four spatial dimensions, and they expect us to do this with 27?

    "Within Philips, technology is available to integrate the device down to a few mm^3."

    The other day when I was forced to surf the web on my phone since my wireless PDA was being used to open a bottle of Corona Extra (la cerveza mas fina) I came upon your idea on slashdot where you proposed a spider-web launching add on. Needless to say, I was shocked! So once the beer was opened I used my Handspring PDA as a telephone and called my VC buddy immediately (though he didn't answer- after he installed that Golf Tee extension to his Nokia we can't get him off the links!)

    Nonetheless I know he would be interested in funding such a usefull gizmo as he has a successful track record of supporting innovation.

    If you are interested I can use my wristwatch to take a digital picture of the contract and fax it to your blue tooth enabled microwave ASAP.

    Uh, dude, I think you're using your mouse upside down. The optical sensor is supposed to be on the bottom of the mouse.
