More Device Motion Experiments with HTML & Adobe DPS

I wanted to follow up my last post on 3D Parallax effects in HTML or Adobe DPS, I’ve decided to release some of the other experiments that I’ve been exploring with device motion in DPS publications. Check out the video below to see two new samples, and a corrected version of the strawberries example from my last post (the plants were going the wrong way in the last post).

All three of these samples leverage the same basic technique for responding to device motion inside of a DPS publication. The motion-interactive components are implemented using HTML and JavaScript, and are included in publications as web content overlays. In JavaScript, it takes advantage of the ondevicemotion event handler to respond to the physical orientation of the device.

In all three of samples, the web content overlay is set to autoplay, with user interaction disabled. This way the HTML & JavaScript automatically loads and the scripting is active, but it doesn’t block interaction or gestures for DPS navigation. I also enabled “Scale Content To Fit” so that HTML content scales appropriately between retina and non-retina devices.

Strawberries

The strawberries sample is identical to the one from my previous post. This is just a capture of the updated motion. You can access the full source project to this sample at:

Adobe San Francisco

The Adobe/inline content example is implemented in the same manner as the strawberries example. The large city image It is a two-layer composition created with Adobe Edge Animate. The foreground building and flag move independently from the background image. I used Photoshop to separate the content into layers and made them animate based on device orientation in the exact same fashion as the strawberries sample. All of the text and image content surrounding the cityscape panorama is laid out with InDesign.

AT&T Park/San Francisco Giants

The AT&T Park/San Francisco Giants example is implemented with basic HTML and JavaScript, no additional tools were used to create this interactive scenario.   The content on the left hand side was all laid out with InDesign. The content on the right side is the interactive HTML.

The image used in this example is a vertical panorama captured from a remote control helicopter. This image contains various perspectives that have been composited in Photoshop. The motion of the device is aligned to match the perspectives in the image/viewport; When the device is facing down, the image is looking down and when the device is vertical, the image faces forward. You can check out the vertical panorama image below. If you’re interested in creating a vertical panorama, be sure to check out this tutorial from Russell Brown.

Vertical Panorama over AT&T Park

The HTML and JavaScript used in this example is fairly minimal. The image is applied as the background of the root HTML <body> element, and the position of the background is shifted based upon the device motion event. This approach keeps the HTML DOM as flat and simple as possible.

Here’s the HTML that makes up this example:

<html>
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no">
        <title>Parallax Vertical Background</title>
        <link rel="stylesheet" href="assets/styles.css">
        <script src="assets/zepto.js"></script>
    </head>
    <body></body>
</html>

… and the CSS styles used to apply the background image.

body {
    background-image:url('att_park_vert_panorama.jpg');
    background-position: center;
}

… and the JavaScript used to shift the position based on the device orientation event. Note: this also uses the Zepto JavaScript library.

window.ondeviceorientation = function(event) {
        var gamma = event.gamma/90;
	var beta = event.beta/180;
	var temp = 0;

	// shift values/motion based upon device orientation
	switch (window.orientation) {
		case 90:
			temp = gamma;
			gamma = beta;
			beta = temp;
			break;
		case -90:
			temp = -gamma;
			gamma = beta;
			beta = temp;
			break;

	}

	// update positions to be used for CSS
	var yPosition = 1200 - (beta * 2200);
	var xPosition = -200 + (gamma * 300);
	xPosition = Math.max( -300, Math.min( 0,xPosition));
	yPosition = -Math.max( 100, Math.min( 1400,yPosition));
	//console.log(xPosition, yPosition);

	// apply css styles
	var css = xPosition + "px " + yPosition + "px";
	$("body").css( "background-position", css);
}

Photorealistic 3D Parallax Effects in HTML or Adobe DPS with Adobe Photoshop and Adobe Edge Animate

A few weeks ago, a fellow Adobe colleague showed me a DPS publication that had an amazing design. All of the content looked great by itself, but what really made parts of it “pop” was that in certain areas there was a 3D parallax effect, which made it feel like you were looking into an image that had depth. You could rotate the device and see what’s hiding behind a person, or around the corner of a building.

Here’s what I mean… on the surface the image looked static, but as I rotated it, elements shifted to give the illusion of depth. The background and foreground elements all moved at different rates:

3D Parallax Effects on a Device

I thought this was an incredible example of added interactivity and immersive experiences, and it’s not really that difficult to implement. In fact, I put together this tutorial to show exactly how you can create these types of effects in your own compositions.

To create this kind of an effect, the first thing you need to do is break apart an image into layers – note: you may need to synthesize edges so that there is an overlap in all transparent areas. Then you need to add interactivity in HTML. Align those images so that their default state looks just like the still image, then move the images based upon the device orientation. I move the foreground one way, keep the middle content more or less stationary, and move the background content the opposite direction (all based upon which way you are rotating the mobile device). Since this is all HTML, you can take this content and use it on the web, or import it into Adobe InDesign to export a DPS digital publication.

Step 1: Create Layered Images

You can either create your own layers, or break apart an existing image into layers so that each individual layer can be placed over top each other to form a seamless composition. In this case, I separated the strawberries, the rows of plants, my daughter, and the sky out to separate layers.

Break Apart Layers in Photoshop

To achieve this, I used the following in Photoshop:

Yes, I did this quickly, and there are still some artifacts visible from the layering process.  :)

Step 2: Create Edge Animate Composition

Next, pull all of those images into an Edge Animate composition so you can create the parallax behavior on the timeline. I actually used the exact same technique that fellow Adobe evangelist Paul Trani uses in his parallax scrolling example.

Edge Animate Composition

The only difference in mine is that I added some simple HTML and JavaScript to handle device-specific behaviors. I added the following:

An HTML meta tag to the root HTML file to prevent device scaling:

<meta name = "viewport" content = "user-scalable=no, width=device-width"/>

JavaScript to disable touch interactions (prevents touch scrolling):

document.addEventListener('touchstart', function(event){
   event.preventDefault();
   return false;
});

JavaScript to handle device orientation – this jumps to a specific point in time in the timeline animation based on the device orientation:

window.ondeviceorientation = function(event) {
   var delta = Math.round(event.beta);

	switch (window.orientation) {
		case 0:
			delta = Math.round(event.gamma);
			break;
		case 180:
			delta = -Math.round(event.gamma);
			break;
	}

   var position = 15000 + (delta * 400);
   position = Math.floor(position);
   sym.stop(position);
   console.log(position);
}

Update 1/7/2014: I added logic to support both landscape and portrait orientation.

Be sure to add both of those JavaScript snippets inside of the creationComplete event for the Stage.  I also over-exaggerated the movement in the timeline.  I think it would look better with slightly less (more subtle) movement.

At this point, you could publish the composition and use it on the web – there’s nothing stopping you at all. In fact, you can check it out here, just load it on an iPad and rotate the device to see the effect. However, please keep in mind that 1) I haven’t added a preloader, 2) the assets are non-optimized and are all retina size , 3) I don’t have it auto scaling for the viewport size, so it will only look right on a retina iPad, and 4) I have only tested this on an iPad – no other devices.

Note: You could also do this without using Edge Animate, but you’d have to hand code the HTML/JS for it.

You can download the source for the Edge Animate project here.

Step 3: Include in InDesign/DPS Composition

To include this in a DPS publication, all that you need to do is export an Animate Deployment Package (.oam file) from Adobe Edge Animate. You can then just drag and drop this into InDesign for inclusion in a DPS publication.

Update: After publishing this I realized that the movement of the plants should actually be reversed.  If you view this link, you’ll see the updated motion (which looks more realistic), but I can’t update the video that’s already been published.

The Web Just Got A Whole Lot More Awesome

Lots of awesome web-related stuff has been happening over the last few days. Here’s a quick summary, with links to learn more…


iOS 7 & Safari have new Web Platform Features

This includes CSS Regions, Clip Paths, and Canvas Blend Modes… read more on the Adobe Web Platform Team blog.


Adobe Edge Reflow & Adobe Edge Code Updated For CSS Regions

Adobe Edge Reflow and Adobe Edge Code now support CSS Regions.

CSS regions is a revolutionary CSS specification draft that allows a deeper separation of concerns in the way designers and developers structure their content and layout. They can now manage the way content should flow across different regions of the page design (hence the name CSS Regions) separately from the content itself . Then content can now be made to flow in different chains of regions, typically laid out differently for a mobile, tablet or desktop/laptop use.

Reflow now supports CSS Regions in the user interface/design surface, and Adobe Edge Code now supports CSS Regions in code hinting. Check out the video below to see CSS Regions in Reflow in action:
