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."

  37. More an optical trackpad by Jeremiah+Blatz · · Score: 1

    This is closer to an optical trackpad than a mouse. Why is it useful? Well, you could use it to replace the up-down/d-pad that many phones have. Instead of two or four big mechanical buttons, you have one tiny non-moving lens. Smaller phones, less breakage.

    Of course, in order for this to work well, there would have to be haptic feedback that you had moved an item, otherwise you'd have to stare at your phone to see where the cursor was. I suspect that this will only become popular in ultra-tiny phones (like ones that you can't buy outside of Asia), and perhaps in palmtops (although I'd much prefer a touch-screen).

  38. They should point out by ImaLamer · · Score: 2
    Although they say "mouse" this is actually a trackball with the trackball removed.

    I'm a very happy user* of a Microsoft Trackball Optical and it is the same thing yet they decided to leave in the trackball instead of using your finger.

    The precision of these optical devices however does let anyone use them almost anywhere (except on glass, mirrors, etc). But if they want to call this a "mouse" it would need to go on the bottom of your phone while you move it around on it's back (or front?)

    *there is a problem where by moving the wires the mouse become disconnected, likely a short. Luckily I use it with the USB port because I can bring it back online without getting on my hands and knees. Anyone had to ship one back to M$? I just found their replacement page here

    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!)

  44. Finally! by cybermace5 · · Score: 2, Insightful

    You know how a trackball is essentially a mouse turned upside down? This is the concept at work here.

    I can't believe it took this long to come up with the optical touchpoint. I can't use those eraser-head pointers, touchpads are always interfering whenever I brush my palm on it while typing. With this technology, all you need is a tiny hole to put your thumb over. For greater accuracy, you could even have a trackball-sized device with the hole on the top and a smooth surface to move your hand on.

    This can also be integrated into a regular optical mouse...your finger can control scrolling and zooming without a wheel.

    Until we have MEMS displays at a virtual 50", we really won't need these in cell phones and PDA's. But it will be great for wearable computing; hold the controller in your hand and point by moving your thumb on the side of the case.

    It's not that these things haven't been done before, it's just that you can now do it more reliably and with better accuracy.

    I was hoping to actually file a patent on this! You can demonstrate the effect by taking an optical trackball and using a fingertip or thumbtip in the cavity created when you remove the ball. I noticed the effect cleaning a logitech device several years ago. The MS trackball also works well. As to "bluetooth" I have used my logitech wireless this way, so I assume it would work for a bluetooth as well.
