4 Why All the Excitement? Unlike laptops and desktops, key smartphones (and Apple products) do not support Adobe Flash HTML5 has new tags that play video and audio in a browser without requiring a proprietary plugin such as Adobe's Flash, Microsoft's Silverlight, or Apple's QuickTime With these capabilities, HTML5 is an alternate for Adobe Flash and the Adobe Flash plugin Why All the Excitement? Makes it possible to design, develop, and publish once and display the published content via each device's browser Reduces cost 1 application for multiple devices ELearning Guild Report: Mobile Learning: Landscape and Trends Session 501 Is HTML5 Ready for elearning?

7 BROWSER Poll #13 12 Session 501 Is HTML5 Ready for elearning? Page 6

8 Browser Functionality The browser s main functionality is to present the web resource you choose, by requesting it from the server and displaying it on the browser window The resource is usually an HTML document, but may also be a PDF, image, or other type The location of the resource is specified by the user using a URI (Uniform Resource Identifier) 13 Browser Support There are five major browsers used today: Internet Explorer, Firefox, Safari, Chrome, and Opera.

21 Adobe Captivate Publish To iphone From Captivate 5 To deploy a Captivate course on an iphone you need Adobe elearning Suite 2, or both Adobe Captivate 5 and Adobe Flash Professional. You also need to install the Packager for iphone from Adobe Labs. 1. Get an iphone developer certificate from Apple 2. Get Development Provisioning profile from Apple (a file that lets you test or distribute an iphone application. You obtain provisioning profile files from Apple. A provisioning profile is assigned to a specific development certificate, an application ID, and one or more device IDs). More details here 3. Create a Captivate project for the iphone form factor 320 * While publishing the SWF, turn ON this option in the publish dialog Enable SWF for conversion to iphone application Session 501 Is HTML5 Ready for elearning?

25 UNDER THE HOOD HTML5 Stack HTML5 the markup language CSS3 (the latest version of Cascading Style Sheets) how it looks or is rendered JavaScript the programming language Session 501 Is HTML5 Ready for elearning? Page 24

26 Areas Of Focus The markup part of HTML5: focused on developing web sites and pages The API (application programming interface) part: focused on building web applications (think of Gmail as an example of a web application) Features New structural and semantic markup Such as header, footer, and nav elements The new canvas element Creating web based bitmap graphics using JavaScript New native audio and video elements, and related elements and attributes Embedding multimedia content that browsers can play without plugins <div id= header >. Header content </div> <header>. Header content </header> Session 501 Is HTML5 Ready for elearning? Page 25

27 Tags <audio> <canvas> <footer> <header> <nav> <time> <video> tag defines sound content tag defines graphics tag defines a footer for a section or page tag defines a header for a section or page tag defines navigation links tag defines a date/time tag defines a video Offline Web Application Enabling resources like HTML, CSS, and JavaScript to be cached, so that if a user goes offline, the browser will have kept these resources and the application can still be used, or even installed locally on a device Sending events to a web application when the user goes on and offline Session 501 Is HTML5 Ready for elearning? Page 26

28 Geolocation API function get_location() { navigator.geolocation.getcurrentposition(show_map);} Allows a web site or application to ask the browser where a user is located (including longitude, latitude, and altitude; but also potentially the direction they are facing, and their speed) Of course, whether the user wishes to share this information is at their discretion Examples Sketching: Drag and Drop: Demonstration of editable text and local Storage; edit text in the box, close the window, and then click the link again: Geolocation: Session 501 Is HTML5 Ready for elearning?

30 Canvas Example Source Code <html> <body> <canvas id="mycanvas" width="200" height="100" style="border:1px solid #c3c3c3;"> </canvas> <script type="text/javascript"> var c=document.getelementbyid("mycanvas"); var cxt=c.getcontext("2d"); cxt.fillstyle="#ff0000"; cxt.fillrect(0,0,150,75); </script> </body> </html> Session 501 Is HTML5 Ready for elearning? Page 29

31 Head <html> <head> </head> </html> Elements inside <head> can include scripts, instruct the browser where to find style sheets, provide meta information, and more. The following tags can be added to the head section: <title>, <base>, <link>, <meta>, <script>, and <style>. Body <html> <head> </head> <body> The body element defines the document's body. The body element contains all the contents of an HTML document, such as text, hyperlinks, images, tables, lists, etc. </body> </html> Session 501 Is HTML5 Ready for elearning? Page 30

32 Canvas <html> <head> </head> <body> <canvas id="mycanvas" width="200" height="100" </canvas> </body> </html> The HTML5 canvas element uses JavaScript to draw graphics on a web page. A canvas is a rectangular area, and you control every pixel of it. The canvas element has several methods for drawing paths, boxes, circles, characters, and adding images. Specify the id, width, and height of the element Draw With JavaScript <script type="text/javascript"> Var c=document.getelementbyid("mycanvas"); var cxt=c.getcontext("2d"); cxt.fillstyle="#ff0000"; cxt.fillrect(0,0,150,75); </script> The canvas element has no drawing abilities of its own. All drawing must be done inside a JavaScript. JavaScript uses the ID to find the canvas element. Session 501 Is HTML5 Ready for elearning? Page 31

33 Draw With JavaScript <script type="text/javascript"> Var c=document.getelementbyid("mycanvas"); var cxt=c.getcontext("2d"); cxt.fillstyle="#ff0000"; cxt.fillrect(0,0,150,75); </script> The getcontext("2d") object is a built-in HTML5 object, with many methods to draw paths, boxes, circles, characters, images, and more. Draw With JavaScript <script type="text/javascript"> Var c=document.getelementbyid("mycanvas"); var cxt=c.getcontext("2d"); cxt.fillstyle="#ff0000"; cxt.fillrect(0,0,150,75); </script> Draw a red rectangle. The fillstyle method makes it red. The fillrect method specifies the shape, position, and size. Session 501 Is HTML5 Ready for elearning? Page 32

34 Draw With JavaScript <script type="text/javascript"> Var c=document.getelementbyid("mycanvas"); var cxt=c.getcontext("2d"); cxt.fillstyle="#ff0000"; cxt.fillrect(0,0,150,75); </script> The fillrect method above had the parameters (0,0,150,75). This means: Draw a 150x75 rectangle on the canvas, starting at the top left corner (0,0). The canvas' X and Y coordinates are used to position drawings on the canvas. SVG Example SVG stands for Scalable Vector Graphics Session 501 Is HTML5 Ready for elearning? Page 33

35 Source Code <svg width="100%" height="100%" version="1.1" xmlns=" <circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red"/> </svg> Canvas vs. SVG Think of the difference between canvas and svg as the difference between Photoshop and Illustrator (One deals with bitmaps and the other vector art With canvas, since you are drawing in bitmap, you can smudge, blur, burn, dodge your images easily. But since it's bitmap, you can't easily draw a line and then decide to reposition the line. You need to delete the old line and then draw a new line With svg, since you are drawing vectors, you can easily move, scale, rotate, reposition, flip your drawings. But since it's vectors, you can't easily blur the edges according to line thickness or seamlessly meld a red circle into a blue square. You need to simulate blurring by drawing intermediate polygons between objects Session 501 Is HTML5 Ready for elearning? Page 34

36 SVG Advantages SVG files can be read and modified by a large range of tools (e.g. notepad) SVG files are smaller and more compressible than JPEG and GIF images SVG images are scalable SVG images can be printed with high quality at any resolution SVG images are zoomable (and the image can be zoomed without degradation) Text in SVG is selectable and searchable (excellent for making maps) SVG works with Java technology SVG is an open standard SVG files are pure XML Video Example Session 501 Is HTML5 Ready for elearning?

37 Source Code <video controls="controls"> <source src="pr6.mp4" type='video/mp4; codecs="avc1.42e01e, mp4a.40.2"' /> <source src="pr6.webm" type='video/webm; codecs="vp8, vorbis"' /> <source src="pr6.ogv" type='video/ogg; codecs="theora, vorbis"' /> <video> File vs. Video Formats One of the biggest sources of confusion about video is not realizing that the file format is completely different from the video format. So you're always dealing with two formats, not one Examples of file formats are.mp4,.flv, f4v,.ogv, or.avi. File formats are often called container formats because they're containers for the actual video The video format is the flavor of compression that's used on the video. This is often called a codec Session 501 Is HTML5 Ready for elearning? Page 36

38 MP4 The movie.mp4 file is a container that can hold video encoded as either MPEG-4 or H.264. Flash A movie.flv (Flash) file could also hold H.264 video, or it could hold video encoded with vp6 or Sorenson Spark. But it can't hold MPEG-4 video. Session 501 Is HTML5 Ready for elearning? Page 37

39 Codec A codec encodes a data stream or signal for transmission, storage or encryption, or decodes it for playback or editing The process of decoding what s inside the video container file varies To know how to decode a movie, the player (which is your web browser in the case of HTML5 video) has to know with which codec the movie was encoded Video File Formats Each format holds at minimum one video track, and most likely, one audio track When you watch a movie online, your video player decodes both the audio and video and sends the information to your screen and speakers Session 501 Is HTML5 Ready for elearning? Page 38

40 Three Parts To Video 1. The file format that holds the video, like.mp4,.flv,.f4v,.ogv, or.avi 2. The video format (aka codec), like H.264, MPEG-4, or Theora 3. The player that makes it available to your site visitors, such as the Adobe Flash plugin, or the new <video></video> tag Codec-Neutral HTML5 doesn t care what format your video file is. Whether it s MP4, WMV, MOV, or whatever it s all the same to HTML5 You can use an incredibly simple set of tags to play video on your web app: <video></video> There are equivalent tags for pretty much any form of media You ll no longer have to worry about whether or not a device can handle a particular kind of file 78 Session 501 Is HTML5 Ready for elearning?
