Real-Time, Detailed Face Tracking On a Nokia N900

ptresadern writes "Researchers at the University of Manchester this week revealed a detailed face tracker that runs in real-time on the Nokia N900 mobile phone. Unlike existing mobile face trackers (video) that give an approximate position and scale of the face, Manchester's embedded Active Appearance Model accurately tracks a number of landmarks on and around the face such as the eyes, nose, mouth and jawline. The extra level of detail that this provides potentially indicates who the user is, where they are looking and how they are feeling. The face tracker was developed as part of a face- and voice-verification system for controlling access to mobile internet applications such as e-mail, social networking and on-line banking."

  1. Finally, something to do with this phone by Anonymous Coward · · Score: 4, Interesting

    I love my N900, it's a shame Nokia doesn't. Still waiting for MeeGo, and to get the best out of my device I've OC'ed it slightly, not to mention transition and touch screen sensitivity tweaks which all make the phone much more usable. What I want to know is why can't they get it right the first time? Since they didn't, how hard would it be to adopt similar tweaks directly into the OS so it doesn't feel so sluggish? It had/has so much potential, but I'm afraid for now, we'll never see it. As soon as Apple releases an iPhone with a slide out QWERTY keyboard, I'm in.

      If I'm not going to treat my phone as a subnetbook, then why do I need an iPhone in the first place? I can make calls onmy cell phone without having to pay Apple for a walled garden.

      ... low amount of apps, etc.

      You can install Debian packages on an N900. It's essentially a tiny ARM tablet running Linux.

      Ahem.

      I had an iPhone before my N900, and frankly I adore the N900. It's fast, responsive, and it's easy to understand what's going on. If the music's skipping (which happened on both devices), I pull up top, then renice my music player. If I want a nice note-taking program, I just run emacs & org-mode on it. Then I'll 'git push' those notes for my other machines. I use citrix to run an app at work (note: despite what the website says, it doesn't actually require motif). The map program (not the stock one, but one you can download a package for) is utterly fantastic. I even have a subway map for my city.

      Really, advanced users of the iPhone really just want a mobile computer, with a phone tacked on. The UI on the N900 is pretty good, and it does what I want with few problems, and many, many wonderful plusses over the iPhone platform.

      Also, it has a keyboard, replaceable battery, and flash :-) I can stream full-screen flash videos in a cab.

      250,000 huh?

      Most of the iPhone apps fall under the following categories:
      -small flash-like games
      -videos wrapped in an app api
      -sound boards

      If you are going to count apps like that, then lets add the following to the n900's list
      -*actual* flash games (addictinggames.com, etc all work)
      -built in unix tools (top, etc)

      I'm fairly certain if you compared these now-equivalent lists, you would probably find the n900 has MANY more apps, and that most of them are probably MUCH better written to boot.

      Oh, did I mention you can literally write your own apps in almost ANY language you want without paying $100 for a developers key. You can even distribute your own software repository publicly without paying a fee or asking users to void their warranties.

      Yeah, 250 000 apps sounds kind of pathetic to me...

  4. The N900 ISN'T (just) a phone by Colin+Smith · · Score: 5, Insightful

    Course, Nokia is a phone company and that's how they market it.

    The N900 is a Linux box, which fits in your pocket, and which can talk to GSM, UMTS, WiFi, Bluetooth, FM transmitter and receiver, infrared transmitter, GPS.. Has an accelerometer, touchscreen, 5MP camera, audio (obviously), and TV out.

    Lets put it this way. The N900 is a general purpose mobile computing module with battery backup that can do everything, talk to everything, uses open standards and is easy to use.

    You can write bog standard shell/python/java/c/ASM/whatever software for it and distribute them as Debian packages.

    Anything you can think of to do with a computer, you can do with the blessing of Nokia and you can do it mobile with full knowledge of location and movement. That is the difference between open and closed.

    No offense or anything, but it's a no brainer.

    No mod points, good post.

    If you filled in the extensive questionnaire Nokia sent N900 owners, you were asked to rate the N900 on a scale from "computer with phone functions" to "phone with computer functions". Nokia understands the issue well. I don't think the N900 is anything at all to do with the iPhone/Android world. It is simply a completely different class of machine, and Nokia's low key approach suggests they regard it as a research vehicle. In exchange for supporting their research, you get a piece of equipment targeted at software developers. Yes, it's slower than an iPhone or recent Android devices. It's heavier. It's clunkier. But it's lighter, smaller and more convenient than anything else which I can use to do the same job.
