Optical Mouse Saves Space in Cellphones 114

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."

      Mobile phones really don't need a mouse/trackball thing. I'd like to see an example of one that does (My phone has a "mouse" button, which is basically like a game controller touchpad. I think they did it to be able to put a cute little mouse picture on the box) Now, the real advantage would come with the second item mentioned: Laptop. I have used laptop trackballs, touchpads, and the little nipple thing. Touchpads are the best IMHO, but after about 5 hours working with one, my hand would cramp up and my finger would go numb. With this thing, I'd just have the hand cramp. It's a step in the right direction. Plus, you get the gee-wiz factor of it looking like something out of a sci-fi movie (see, I wave my finger over this spot, and something happens!) For PDA's, take it or leave it, Personally, I'd leave it, since a stylus is more versitile than a mouse.

      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...

      • just wanted to tell you that I've personally played two different ports of DOOM with a Nokia 9110. Both support shareware and registered .wad's, one of them can even do DOOM2, and I've heard there are other versions as well... :)

      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.

    • well then you've obviously never seen a japanese cell phone. those things are 4 inch monsters. they have all the features that ours have but they also have a built in digital camera (the quality and refreshrate is mind blowing) that can snap shot, save, send and stream videos to the people they call. now THAT'S what i call a phone!
    • Well, if you integrate a bluetooth chip in the phone as well, you've got a wireless optical mouse for your laptop, as well as a wireless modem. and, as has been noted, there's the replacement for a scroll thing, and as screens increase in size and UI's in complexity, easier selection of options.

  • 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).
  • 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 [microsoft.com]

    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.

  • The only pointing device that should be on hand-held devices is my finger! This is a step backward from touch-screens.
