  1. David Welsh

  2. Traditional Reading • Eye seeks “Optimal Recognition Point” • Start to process the meaning of the word • Eyes move, called a “saccade” • Processing the words for meaning and context • 20% processing 80% movement

  3. Rapid Serial Visual Presentation • Developed to measure reactions to content • Words are displayed left-aligned or centered • Not ORP™ centered • Still requires some eye movement • Developed before heavy web use

  4. Spritzing™ • Content has ORP™ located at the focal point • Read without having to move your eyes • Eyes can focus on about 13 characters at a time • Variable WPM rate, 100-1,000 • Positioning without eye movement helps process words, especially at speed

  5. Spritzing™ 13 Character Focus

  6. PoweredbySpritz™ • Developer program • SDKs and APIs for Android, iOS, and JavaScript • Last week started JavaScript access • Next up, Android and iOS

  7. Web Development • Hosted Spritz JavaScript SDK • Login html only required file • CSS and JS: fonts, images, styles • JQuery library <script type="text/javascript" src="//sdk.spritzinc.com/jQuery/jquery-2.1.0.min.js"></script> <script type="text/javascript" src="//sdk.spritzinc.com/js/1.0/js/spritz.min.js"></script>

  8. Redicle • Visual frame embedded with the Spritz JavaScript SDK • Link content to the redicle <p><div data-role="spritzer" data-url="http://www.myserver.com/~mywebdirectory/ContentToSpritz.htm"></div></p>

  9. Redicle features • Controls the notifications and handlers • Can control multiple sources of text • Easily duplicated • Customize with some permanent properties • Configured for different devices • Multi language capable

  10. Default Configuration varspritzerOptions = {         "redicleWidth" :     340,         "redicleHeight" :     70,         "defaultSpeed" :     250,        "speedItems" :         [250, 300, 350, 400, 450, 500, 550, 600],        "controlButtons" :     ["back", "pauseplay", "rewind"],         "controlTitles" : {             "pause" :         "Pause",             "play" :          "Play",             "rewind" :        "Rewind",            "back" :          "Previous Sentence"         }  };

  11. SpritzerController • Lets you spritz text arbitrarily • Text must be a "spritzable" format • Set a language in HTML tag <html lang="en"> varonStartSpritzClick = function(event) { var text = $('#inputText').val(); var locale = "en_us;";     // Send to SpritzEngine to translate SpritzClient.spritzify(text, locale, onSpritzifySuccess, onSpritzifyError); };

  12. Current Web Interface
