Webcam stories

Pressure. It's all coming along. This Saturday, the Art Tech Seminars at Assembly Summer in Helsinki, Finland, 7th of August at 2.00PM. WebCam stories.

If you want to experience the potential of Flash and a typical webcam to achieve face recognition, eye tracking and motion detection, using real-time image processing, come and see. I will share how we can use our often dusty and under-used webcams to make our eyes less tired after hours of gazing into pixels.

Another good news is that HiSlope toolkit will be finally released there.

Although the Flash Player is recently being eschewed in favour of emerging HTML5+JS technologies (most notably by Apple), I will prove it still offers decent processing power and support for external devices such as webcam and microphone (which HTML5 is not yet capable of) and can significantly contribute to improving real human-computer interfaces.

Thanks to Justyna for a cheeky title :)

PS I also got the chance to speak at the Elevator Pitch this Autumn, which is part of Flash on the Beach conference in Brighton, UK (26-29 September 2010) – my very own 3 minutes!

Old skool TextField plasma (dithered)

I had a quick poke into FontStruct last nite, some useful features had been recently added to that awesome online block font editor. I found one of my previously designed fonts called RUdigit?, it's pretty (experi)mental (check the pixel size, otherwise you won't get the idea).

That reminded me of an old Flash AS1 experiment of mine, where I tried to use predefined character set to display various shades of grey. We used to do it a lot in the C64 demoscene days – nostalgia had kicked in and I quickly mocked up an AS3 version of that old triple sinus plasma code.

Click the face above to launch, hit SPACE to randomise the plasma periods. And now get ready for the trick: try selecting the pattern as you would do with normal text.

No Pixel Bender here, just pure TextField™. It's pretty slow I must say but I didn't spend a second to optimise it. Maybe drawing a single character onto a bitmapData or using copyPixels would work faster? I might look into that again, most likely when the C64 nostalgia takes me over again sometime.

If you are new to this technique, have a sniff into the source. TTF font included. Enjoy.
