6. Small UIs data sent from microcontrollers

7. Embedded or Remote HTML/JS control physical world with web based UI!

11. void indexCmd(HTTPServer &server, HTTPServer::MethodType type, char *, bool) { server.httpSuccess(); P(indexHTML) = "<!DOCTYPE html>n" "<html>n" "<head>n" "<meta name="viewport" content="width=480px, user-scalable=no">n" "<title>ATV</title>n" "</head>n" "<body>n" "<div class="swipe-container container"></div>n" "<div class="buttons-container container"></div>n" "<script data-main="https://www.cs.helsinki.fi/u/ljlukkar/appletv/js/main.js" n" " src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.1.10/require.min.js" ></script>n" "</body>n" "</html>"; server.printP(indexHTML); } CSS Opportunities: Basic UIs Microcontrollers serve index pages with remotely loaded JS & CSS source: https://github.com/lasselukkari/aWOT Arduino sketch (.ino file): "<link rel="stylesheet" type="text/css" href=" https://netdna.bootstrapcdn.com/bootstrap/3.0.3 /css/bootstrap.min.css" />n" "<link rel="stylesheet" type="text/css" href="https://www.cs.helsinki. fi/u/ljlukkar/appletv/css/custom.css" />n"

15. Embedded or Remote 1. Files can be served off of an SD card - Not terribly fast, but so far seems to work. 2. Local network can store your JS and CSS files - point to those as external resources. 3. Local web server -client request data direct from microcontroller 4. Microcontroller push data to the server database. photo credit: http://internetofthings-pune.blogspot.in/2013/07/this-is-open-source-home-automation.html

16. Embedded CSS Problems 1. Try to embed CSS into microcontroller and does not compile 2. Use image links as buttons or Styles were generated at www.cssbuttongenerator.com 3. Buggy JS to change CSS properties according to the status of microcontroller 4. client.println("<style type="text/css">"); 5. “The stylesheet is optional…” 6. Usual drab grey buttons in your web browser but the application will still work.

17. Handcrafted V.S. Online Generated

18. Interactive TVs “Websites are never going to look that great on a TV unless they are designed for their resolutions...” CNET TV Reviewer “a Linux device configured with a Webkit-based browser to run web pages and applications” https://securityledger.com/2013/08/samsung-smart-tv-like-a-web-app-riddled-with- vulnerabilities/

19. e.g. Google TV Design Principles source: https://developers.google.com/tv/web/docs/design_for_tv

20. Layout 1. achieve “intended layout” using float, calc() or flex box 2. resolutions (720p or 1080i/p) div { border: solid 1px; float: left; margin: 1em; padding: 0 1em; width: calc(100%/7 - 6em); }

21. Scrollbars 1. overflow: hidden on the body 2. use JS to move content into view <script type="text/javascript"> function MoveIntoView (alignToTop) { var element = document.getElementById ("elementID"); element. scrollIntoView (alignToTop); } </script> html, body { height: 100%; overflow: hidden; }

22. CSS Zoom property 1. impacts quality and performance 2. design expecting white space around pages img { zoom: 1; */ normal */ } img:nth-child(2) { zoom: 200%; */ percentage or number e.g. 2 = 200% /* }

23. div { border: solid 1px; float: left; margin: 1em; padding: 0 1em; width: calc(100%/10 - 9em); } .. div:nth-child(8), div:nth-child(9), div: nth-child(10) { display: none; } Selections above the fold 1. reduce categories 2. hide DIV elements with “display: none”

24. Browser Specific 1. Check HTML5 Rocks 2. Browser specific support 3. *Others: OperaTV Browser, Kylo div { -webkit-transform: scale(1.5); } div { -webkit-transform: scale(2.0); }

25. HTML5 Elements <button> & <canvas>

26. <button> “use a button element. They can be beautifully styled, have in-built keyboard support and various states, and they can even be disabled using an attribute. By using attribute selectors in your CSS you can style them.” Christian Heilmann. Smashing Book #4 — New Perspectives on Web Design. Chapter 3 The Vanilla Web Diet

50. <canvas> “Because the canvas is an HTML element, you can use CSS styles to modify its position, assign it a background color or image, add a border, and so on. In Safari and other WebKit-based browsers, you can use WebKit transitions to smoothly animate changes in CSS properties. Because the canvas can have a transparent background, you can use CSS to create animated graphics that roam freely across the webpage.” https://developer.apple.com/library/safari/documentation/audiovideo/conceptual/html- canvas-guide/ModifyingtheCanvaswithCSS/ModifyingtheCanvaswithCSS.html

55. Data Acquisition Systems Require Data Visualizations Presenting Information, driving complex analysis

56. CSS Based Data Visualizations make it easier for users to grasp data e.g. line graphs, gauges, cards & notifications

57. SVG “SVG content styled with CSS [CSS2]: CSS is a widely implemented declarative language for assigning styling properties to XML content, including SVG. It represents a combination of features, simplicity and compactness that makes it very suitable for many applications of SVG. SVG Tiny 1.2 does not require support for CSS selectors applied to SVG content. Authors must not rely on external, author stylesheets to style documents that are intended to be used with SVG Tiny 1.2 user agents.” http://www.w3.org/TR/SVGMobile12/styling.html

58. SVG cont’d “The ‘class’ attribute assigns one or more class names to an element. The element may be said to belong to these classes. A class name may be shared by several element instances. The ‘class’ attribute has several roles: As a style sheet selector (when an author wishes to assign style information to a set of elements).” http://www.w3.org/TR/SVGMobile12/styling.html

59.

73. Experimental bleeding edge videos & projects

74. Arduino Light Animation http://vimeo.com/79962595 based on CSS animation properties

76. 3D Printing from CSS 3D Transforms #tridiv { perspective: 800px; position: absolute; overflow: hidden; width: 100%; height: 100%; background: #08182f; font-size: 100%; } .face { box-shadow: inset 0 0 0 1px rgba(0, 0, 0, 1); } .scene, .shape, .face, .face-wrapper, .cr { position: absolute; transform-style: preserve-3d; } .scene { width: 80em; height: 80em; top: 50%; left: 50%; margin: -40em 0 0 -40em; } .shape { top: 50%; left: 50%; width: 0; height: 0; transform-origin: 50%; } photo credit http://tridiv.com | http://www.thingiverse.com/thing:86078

77. Design Principles

78. Resources V.S. Maintenance V.S. Memory

79. Modularity Easily swappable standardized components form the different user interfaces http://codepen.io/uxcodeine/pen/f3da533b43ebeeea383c9c2b393cf0ba button { padding: 10px 20px; background: #111; -moz-border-radius: 21px; -webkit-border-radius: 21px; border-radius: 21px; border: 1px solid #666; outline: none; font-size: 14px; color: #eee; text-transform: uppercase; } button > span { display: inline-block; position: relative; font-weight: 100; top: -1px; } .group button { margin: 0 !important; } .group button:first-child { border-top-right-radius: 0; border-bottom-right-radius: 0; } .group button:nth-child(2) { border-radius: 0; -webkit-border-radius: 0; margin-left: -5px !important; } .group button:nth-child(3) { border-top-left-radius: 0; border-bottom-left-radius: 0; margin-left: -5px !important; }

80. Efficiency Support flow (DOM) with lessened friction http://codepen.io/uxcodeine/pen/KkEax component02= #CCC article for div in 2 4 6 8 9 11 13 15 18 20 22 24 25 27 29 31 34 36 38 40 41 43 45 47 50 52 54 56 57 59 61 63 65 67 div:nth-child({ div }) background component02 i = 0 l = 64 while i < l i++ $("body.checkers article, body.othello article").append(" <div></div> "); $("body.checkers aside").append(" <div></div> ");

81. Responsiveness Adaptable layouts, not pixel perfect! http://codepen.io/uxcodeine/pen/nyuDE div:first-child { width: 99.5%; } div:nth-child(2), div:nth-child(3) { width: 49.35%; } div:nth-child(4), div:nth-child(5), div:nth-child(6) { width: 32.75%; } div:nth-child(7), div:nth-child(8), div:nth-child(9), div:nth-child(10), div:nth-child(11) { width: 19.4%; } div:nth-child(12), div:nth-child(13), div:nth-child(14), div:nth-child(15), div:nth-child(16), div:nth-child(17), div:nth-child(18), div:nth-child(19) { width: 11.9%; } div:nth-child(20), div:nth-child(21), div:nth-child(22), div:nth-child(23), div:nth-child(24), div: nth-child(25), div:nth-child(26), div:nth-child(27), div:nth-child(28), div:nth-child(29), div:nth- child(30), div:nth-child(31), div:nth-child(32) { width: 7.1%; }

82. Flexibility Support design iterations with less code http://codepen.io/uxcodeine/pen/znLdc students = [["Matthew", "Ash", "(IEP)", 44, 30, 10], ["Ayala", "Miguel", "", 5, 70, 15], ... $.each students, (index, value) -> $("#compare").append "<article> ... </span><span class=' progress " + (if (value[3] < 85) then "atrisk" else "thrive") + "'> " + value[3] + "%</span><span class=' mastery " + (if (value[4] < 85) then "atrisk" else "thrive") + "'>" + value[4] + "%</span><span class=' attendance " + (if (value[5] < 85) then "atrisk" else "thrive") + "'>" + value[5] + "%</span></article>" .results article .progress, .mastery, .attendance &.thrive color: component02 &:before content: "+" border: solid 1px component02

83. #IoT needs more CSS! “… The expertise required to make an Internet ‘thing’ is vast. However, this means that the playing field for making such a connected device is astonishingly level. Whatever your skills and interests, you are well placed as anyone to start experimenting and building. There really is no better time to enter the exciting world of the Internet of Things” Adrian McEwen, Hakim Cassimally. Designing the Internet of Things. Chapter 1 The Internet of Things: An Overview
