Apple's All-Seeing Screen 447

Posted by ScuttleMonkey from the don't-leave-this-on-by-accident dept.
Based on a recent patent we may be seeing a new kind of display coming from the Apple store in the near future, one that can capture images as well as display them. From the article: "The clever idea is to insert thousands of microscopic image sensors in-between the liquid crystal display cells in the screen. Each sensor captures its own small image, but software stitches these together to create a single, larger picture."

A nervous tic, an unconscious look of anxiety, a habit of muttering to yourself -- anything that carried with it the suggestion of abnormality, of having something to hide.

    Kodak's patent mentions previous research suggesting a correlation between age and the way pupils react to light. As a person gets older, their pupils have greater difficulty widening to cope with dim light, it says. The company suggests that an age-verification system could take mug shots of a person from a set distance in controlled lighting, using a flash. Software would then measure the size of their red-eye dots to determine how wide their pupils are and make an estimate of their age.

    I wonder if a picture of an older person with the red eyes in would fool such a sampling.

  • The iSight video camera was distinctive back when it was introduced for two reasons (versus most other web cams commonly used at that time). First, it connected via FireWire. Second, it came with mounting brackets (included, for free in the iSight box) to attach the camera securely to the top center of Apple's LCD monitors and laptop screens.

    The result of this second "innovation"? iSight video confernces looked significantly more natural and more natural than web conferences hosted using Logitech and other web cams that (typically) sat to the bottom right or left of the computer monitor (or awkwardly on top) and, hence, gave participants really skewed views of each others' faces.

    The innovation described in TFA is the logical next step of this eminently sensible design decision that Apple has been promoting for years.

    (Side note: the reason why the iSight demos in Apple keynote addresses look so darn good is that the participants are looking at the iSight camera, and not at the actual screen when they're doing the demo. It's a very subtle shift, but it still matters. Kind of a clever, sneaky way to make the product look even better than it actually does.)

      Number one, iSight cameras aren't even remotely as popular as all the PC USB-based webcams; they're EVERYWHERE, and ISPs for years have been giving them away as freebies. Number two, the iSight wasn't distinctive because of its interface; webcams have been available for years with USB2. I strongly suspect it was firewire because most people NEED their USB ports for keyboards and mice, but don't really use their firewire port except for occasional camcorder use, if at all.

      The iSight was distinctive because:

      • Physical appearance A bit of cheap cast aluminum looked a hell of a lot better than a few cents of plastic.
      • Autofocus
      • A relatively large CCD size for lower noise (a larger CCD also makes optics easier/less critical)
      • built-in microphone specifically designed for the purpose
      • A somewhat decent lens
      • Privacy shutter

      The mounting devices just make it slightly more convenient to attach the camera, particularly if you had an Apple LCD. It's a problem solved with a little bit of tape, by the way.

      Another "by the way"- the iSight cameras in the Macbook and iMac absolutely SUCK. They're basically cellphone cameras; microscopic lens and CCD, no autofocus. No privacy shutter. The picture is very noisy and low resolution, the colors are funky...

There are alternatives that use frustrated total internal reflection, but currently these require rear projection - not feasible for a tablet. See http://mrl.nyu.edu/~jhan/ftirtouch/ [nyu.edu] if you haven't already.

    Incorporating sensing elements within the display will permit sensing multiple simultaneous points of contact of arbitrary size/shape in a tablet form-factor. Neat!

    Apple's been patenting lots of touch-interface concepts recently, too. Vide. [uspto.gov]

    This patent is probably more about touch-screens than screen as scanner (that'd be a neat trick too, but probably would require too much resolution) or camera (would require a different but perfectly calibrated refractive element at each sensor - probably impractical).

Even though your finger may be very large, it approaches a specific point as you touch the screen. So you might 'touch' several on-screen buttons, but the mac would know (or at least have a better idea) which one you were trying for.

    The patent application [uspto.gov] mentions a number of applications: (1) video conferencing, (2) using the screen to replace the camera in multi-function portable devices like PDAs and mobile phones, (3) medical probes that must capture an image and supply their own illumination.

    Slashdot user Isaac mentions the idea of using this for a touch sensitive display. I couldn't find this mentioned in the patent application, so the race is on to file a follow-on patent!

    But you wouldn't actually have to touch the screen. Years ago, MIT built a user interface called "put that there" that did gaze tracking and voice recognition, so that the "mouse pointer" was pointing at whatever object you happened to be looking at on the display. No need to touch a mouse, you just use your gaze. That might be possible with this technology. It could also be used to interpret hand gestures and facial expressions, and use them as input.

    I personally think it would be cool to build a software-programmable mirror. Think of a bathroom mirror with zoom functionality, image enhancement functions, etc. The extra functions are activated by hand gestures, and face recognition is used to determine the centre of zoom (because in a bathroom, you normally want to zoom in on your face).

    I hope Homeland Security doesn't get wind of this. The patriot act allows covert surveillance where they law forces companies to remain silent about what they turn over. I wonder if there's a provision in it (it's so huge I haven't had time to read it, like many of the lawmakers who hurredly passed it into law) to allow the government to force companies to put backdoors into their products for this type of thing without telling consumers. Closer and closer to 1984... Trust the little LED all you want, I won't be buying one of these.

  • AT&T Patented something like this ages ago... (Score:3, Interesting)

    ...back in the 1990s, I was helping someone who was involved with a technology called the optical waveguide display, developed in part by Imperial College, London. This had the ability to emit and receive light. As part of my work I was doing some research and came across a patent by AT&T that described a system similar to Apple's. Of course, it is possible AT&T's patent expired and/or Apple are doing something different. Either way, the privacy issues are interesting as it will not be possible to include a physical 'lens cap' for peace of mind. Also, this would be ideal for an 'instant' scanner. IE, lay item to be scanned on your display, and it's 'scanned' in a flash. No more moving scan head! Forget 30fps video, we could be talking 30fps scanning! (Using a commercial application of the technology.) The LCD photocopier? Ooh!
