After the presentation at FITC on Flash Lite and Mobile Development, a few people asked for my presentation file. I’ve converted it to PDF, grab it here. This is only my part of the presentation – i.e. not including Dongyub’s (his presentation was created using fancy 3D authoring tool; mine is plain basic).

We ran into some technical difficulties (what’s new?) at the conference: No Wi-Fi signal and no mobile phone signal (room was in the hotel basement level!) – both were needed for some demos (Chumby and apps on the phone). Luckily, I had some files on the laptop that were available.

Our own “Elmo”:

Another thing people might have noticed: We didn’t use the Elmo (device projector) provided by FITC. I tried it last year and found the quality was less than desirable. During this year’s technical rehearsal, we noticed it had issue projecting some device screens and produced moire patterns. So I decided to use my own method.

Instead of using the Elmo that outputs S-Video signal, I connected my Sony TRV900 3-CCD DV camcorder to the laptop with a firewire cable, and created a simple Flash Video Viewer (Flash Player 9) to display the video on screen (so everything is projected digitally with the rest of the presentation). Because of the way the camera was positioned, I added code to flip the image upside-down (which is projected right-side-up).

Here’s the (ActionScript 3.0) code:

//=========================================================================

var cam:Camera = Camera.getCamera();
cam.setMode(640, 480, 30);

var vid:Video = new Video();
vid.width = 640;
vid.height = 480;

// flip image upside down
vid.rotation = 180;
vid.x = 640;
vid.y = 480;

vid.attachCamera(cam);
addChild(vid);

//=========================================================================

function keyHandler(evt:KeyboardEvent):void {
    switch (evt.keyCode) {
        case Keyboard.UP:
            vid.rotation = 180;
            vid.x = 640;
            vid.y = 480;
            break;

        case Keyboard.DOWN:
            vid.rotation = 0;
            vid.x = 0;
            vid.y = 0;
            break;
    }
}

stage.addEventListener(KeyboardEvent.KEY_DOWN, keyHandler);

//=========================================================================

Perhaps other presenters may find this useful as well.
