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."

      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.

      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.)

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.
