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."

    Since when has a mobile phone needed a trackpad/mechanical trackball anyway? We all seem to get along fine with up and down buttons...

    More reliance on mice and pointing technologies.
    Since it won't work as awell as a stylus (Hardwriting recognition) And you don't have as much room to find things as a nortmal 17" Screen, I'd have to wonder at the usefullness.

    Cool points for using a laser, though.

    Being one of those jerks who talks on my cell phone a fair amount (I do try to be considerate, honest!) I have to say that reducing the number of moving parts in the phone sounds like a wonderful idea. My biggest problem with cell phones is how flimsy they are, and how quickly parts of them wear out. if this improves the MTBF for the phone, I say bring it on!

  5. Why... by Carik · · Score: 5, Insightful

    ...does anyone need a MOUSE (or any pointint device!) on their cellphone? Frankly, I don't use much more than the number keys and the "start call" button. I honestly can't imagine why anyone would WANT to use their phone for something else. If I want to play games, I go find a computer or a console - or a deck of cards!

      I had a nice Sony phone with a scroll-wheel/button on the side. It was sweet for scrolling through menus, phone numbers, etc. Very nice.

      Problem is, this mechanical bit was the first thing to die. I had a couple of these phones, and friends with these phones, and the scroll-wheel was almost always broken or flakey.

      An optical version of this, with no moving parts to wear out, would be a nice feature. And since you are not limited to one-dimensional movement as you are with a scroll wheel, new navigational ideas are possible (how about the entire alphabet on the screen, you just mouse over the the letter you want and tap, and it jumps to that letter in your phone book. I'm sure others can come up with better ideas.)

      And, of course, when DOOM is ported to a nice J2ME enabled phone, you're going to need something better than the keypad...

      Any pointing device is called a mouse these days, whether or not it's much like a mouse, as the average luser doesn't know what "pointing device" means.

      On a phone it's useful to be able to move through menus, text fields, and hypertext pages (WML or similar) quickly and fluidly. A roller only covers one axis; a small joystick covers both but can't be miniaturised that far; something like this could be ideal.

    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.

    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.
