PowerBook As A New Kind Of Human Interface Device

An anonymous reader writes "As covered earlier on Slashdot, Amit Singh had shown how to access and use the motion sensor feature in the late model PowerBooks for innovative things, which created quite a buzz in the Mac community. In an ingenius new article, Singh has taken the idea all the way and released software which lets you use a PowerBook with a motion sensor as a general purpose input device which works with existing apps. IMHO the coolest use of this is for playing games: be sure to check out the video footage in the article. For instance, in a car racing game, you steer by tilting the PowerBook left and right, go faster by tilting it forward, brake by tilting it backwards! You can also scroll in apps. Google Map scrolling with my PowerBook feels like flying in an aiprlane over the terrain. I must say you have to try this in real life to appreciate the experience ... go to the Apple store or something if you don't have the hardware ;-) Before this my girlfriend (who uses a Dell notebook) has never called anything computer related "jawdropping"! Wouldn't it be nice to have a gaming motion sensor be standard issue in all future laptops?"

[+] Apple: Experimenting With Light on Apple Laptops 120 comments
venkatg writes "Soon after Apple introduced sudden motion sensors in their PowerBooks in early 2005, Amit Singh had shown how these sensors can be used for creative purposes (covered by Slashdot earlier as Having Fun With PowerBook Motion Sensors and PowerBook As A New Kind Of Human Interface Device). This time around Singh discusses 'Experimenting With Light' in a new article whereby by light he means the ambient light sensors and the illuminated backlight keyboard sensors in Apple's laptops. The article shows (source code is included) how one can measure ambient light and do things with it. It also shows things like how to get/set illuminated keyboard brightness and display brightness or do fade transitions of the keyboard lighting. So now that we have all these motion and light sensors under control, is there a MacBook discotheque in the works?"

      Depending on how you have your power settings, the HD is probably going to be asleep most of the time anyway. And the gentle motion you're talking about here is hardly going to be enough to phase a laptop drive - I've got a portable storage device that uses a laptop drive and had it sucessfully write a whole GB of data while I was walking quickly and had it in a pocket in my shorts.

    • "How much good all this tilting and stuff does the hard drive. I'd think it caused some undue wear and tear"

      The solution to this is to market a keyboard with the same capabilities. This keyboard could be plugged into the Powerbook, at which point it would disable the Powerbook's internal "shake controller". Then you could rag on the keyboard without worrying about shaking up the Powerbook. It makes it less portable, of course...

Even though it wasn't 3d/stereo (the only possible improvement), it was so awesome. They had a good FPS game running (I think either GLQuake or Quake II at the time) and it was the greatest thing in the world. Just as good as you can imagine--walk with the arrow keys on a keyboard, shoot with 'control', but you could look around with your head, rather than the mouse.

    It worked perfectly. Just what VR should be. Better than the those big, clunky, slow things at the mall; probably as good as what was imagined by Gibson. Better than what was shown in that crappy movie with Michael Douglas and Demi Moore, based on the equally crappy Crichton book. Perfect, perfect, perfect--very fast, no delay at all, nothing unnatural about it. Just turn your head, look up, and that's what you see. Exactly what you would expect.

    While I doubt that a notebook is an ideal platform for this type of gaming, mainly because the keyboard is difficult to hit while tilting the notebook (you need both hands), I can see that Amit Singh has already thought about either selling the idea, the software, or patenting it, since his licence is only for a 10 minute demo preview. Apple might be wanting to include this software, or possibly even games that use it, in future macs.

    Also, from the original submitter's story:
    Wouldn't it be nice to have a gaming motion sensor be standard issue in all future laptops?"

    I think that Sony, Nintendo and Microsoft have more to gain by making game controllers that use this technology. A lot of people, me included, don't like the tiny joysticks or pads on standard controllers. A controller using this technology would be much more natural. In fact, I'm postive that it will end up being used pretty soon.

    Apple, or Amit Singh would be crazy not to patent the idea.
