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

Haptic Devices
• Omni
• Wrist band
• Novint
• Jacket
• Gloves
• Way more …
HTML5 Haptics

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

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 very very Dangerous!
HTML5 Haptics

Plugins
• Active X
– Microsoft Internet Explorer
• NPAPI (very low-level)
– Google Chrome
– Firefox
– Opera
– Safari
HTML5 Haptics
Mohamed Mansour
18
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

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

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
HTML5 Haptics

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.

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

Prototype, Needed?
• Proof of concept needed to prove that Haptics
needs love! And the future of computer
human interactions!
• Rescue …
HTML5 Haptics

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

Glimpse of Plugin Code
HTML5 Haptics

38
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.
HTML5 Haptics
Mohamed Mansour
39
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));

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 GitHub from here:

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.
