  4. Vision • Haptics Integration into HTML5 • Rich JavaScript API to communicate to Haptics • Cross platform • Haptic device independent • Standardized in W3C Mohamed Mansour

  5. HTML5 Haptics Standardization 3 1 2 5 4 6 7 Mohamed Mansour

  7. HTML5 INNOVATION Mohamed Mansour

  8. What is HTML5? Mohamed Mansour

  9. HTML5 New features • Storage • Application Cache • Web Workers • Web Sockets • Notifications • Drag and Drop • Geolocation • Semantic Tags • Link Relations, and Microdata • ARIA • New form fields • Audio and Video • Canvas and SVG • Font Text Support, • Opacity, Rounded Corners • Shadows, Gradients • Backgrounds, Transitions • Transformations, Animations • Device • A lot more! Mohamed Mansour

  12. Haptics • Technology that interfaces with the user through the sense of touch [definition] • The process of recognizing objects through touch [another definition] Mohamed Mansour

  13. Haptic Devices • Omni • Novint • Gloves • Wrist band • Jacket • Way more … Mohamed Mansour

  14. How they work? • Robotic • Sensors • Feedback • Ex: • You send forces to the device, and it magically moves. • You request positional data from the device. Mohamed Mansour

  16. HTML5 Haptics Standardization 3 1 2 5 4 6 7 Mohamed Mansour

  17. Plugins • Browser plugins is the only way you can allow the user to communicate to native code. • Current state of HTML is still limited … look at Flash, why did it exist? • Can do almost anything! • But very veryvery Dangerous! Mohamed Mansour

  18. Plugins • Active X • Microsoft Internet Explorer • NPAPI (very low-level) • Google Chrome • Firefox • Opera • Safari Mohamed Mansour

  19. NPAPI • Very long name …. Netscape Plugin Application Programming Interface. • Very powerful! • It is just a single library (.dll, .so, .plugin) file that gets loaded. • You just need at least 3 Library Exports: • NP_GetEntryPoints • NP_Initialize • NP_Shutdown Mohamed Mansour

  20. NPAPI Architecture Plugin LOGIC <embed> 3 1 2 DLL EXPORTS ScriptabletoNPObject* 5 4 Browser API NPN_* Mohamed Mansour

  23. Google Chrome • Multi Process Browser • Tab, Plugins, Renders, Extensions, Browser • Very fast JavaScript and Rendering • GPU Accelerated Canvas and WebGL • Secure Sandbox, for Plugins • Very fast at implementing HTML5 features. • Open Source browser Mohamed Mansour

  25. HTML5 Haptics Standardization 3 1 2 5 4 6 7 Mohamed Mansour

  26. Google Chrome Extensions • Small software that can modify and enhance the functionality of Google Chrome. • Using web technologies, HTML, JavaScript, and CSS. • Easily expose NPAPI functionality. • Separate Process Mohamed Mansour

  27. Chrome Extension Basics • Background page • Lengthy process, long lived, singleton. • Browser Actions / Page Actions • Desktop Notifications • Override Pages • Browser Interaction (Bookmarks, Cookies, History, Events, Management, Windows, Tabs) • Plugin Interaction. Mohamed Mansour

  29. HTML5 Haptics Standardization 3 1 2 5 4 6 7 Mohamed Mansour

  30. Prototype • HTML5 Device Tag <device> • Interface • Type Mohamed Mansour

  31. Device Tag • Still in implementation (research phase) • It can change! Add a Haptics “type” Dreamy Ex: <p> To start, Select a haptic device: <device type=haptic onchange="update(this.data)"></p><script> function update(stream) { console.log(stream.data); } </script> Mohamed Mansour

  32. Prototype , Needed? • Proof of concept needed to prove that Haptics needs love! And the future of computer human interactions! • Rescue …  Mohamed Mansour

  33. Prototype, Chrome Extension • How do we do it right now! • HTML5 (Web Workers) • CSS3, Canvas (WebGL Context Graphics) • Chrome Extension • Dedicated Thread (Background Page) • Haptics Controller (Browser Action) • Page Interactions (Page Action) • Accessibility (ARIA) • NPAPI • Haptics Plugin communicates to Chrome Extension • C++ extreme (scene graph, triangles) collision detection algorithms Mohamed Mansour

  36. Architecture C Plus Plus • High Level Novint Device HTML5 Mohamed Mansour

  37. Architecture Plugin Plugin Module Plugin Gate Scripting Bridge Haptics Service NP_GetEntryPoints NP_Initialize NP_Shutdown  Haptics Device Utils Haptics Signal Mohamed Mansour

  38. Glimpse of Plugin Code Mohamed Mansour

  39. Architecture, Extension • Browser Action to act as the controller • Background Page, to allow the plugin to live forever. • JavaScript for Some Collision Detection, Haptic Loop, and Rendering Loop. Mohamed Mansour

  40. Framework • O3D JavaScript API for creating rich and interactive 3D application in the broswer using Canvas, WebGL context. • Haptics API • void startDevice(); • void stopDevice(); • void sendForce(double[3]); • double[3] position; • addEventListener(‘servo’, function(Haptic data)); Mohamed Mansour

  41. Open Source’d Release it to the public! That is how I learned how to code, give back to the community! You can fork it from GitHubfrom here: http://github.com/mohamedmansour/haptics-chrome-extension Mohamed Mansour

  42. Working Prototype Mohamed Mansour

  44. HTML5 Haptics Standardization 3 1 2 5 4 6 7 Mohamed Mansour

  45. Future • Present this to the W3C Developer Group • Help Google Chrome complete <device> tag implementation. • Implement the Prototype again using the <device> tag. • Implement webpage interactions, like annotated YouTube Videos to feel video touch. Mohamed Mansour

  46. Done! Thank you, questions? 3 1 2 5 4 6 7 Mohamed Mansour
