the Timeline
● Everything that you’ve done and received
● The most recent appears on the left, the oldest disappears on the right
● Composed of Cards

Voice
“OK, Glass” followed by a
command
Trackpad
● Click : activate/select/OK
● Swipe down: go back
● Swipe left/right: navigate the
timeline
● Swipe down with 2 fingers: exit
● Camera button: take a picture /
record a video
● Power Button (several
secondes): turn on / turn off
● Backwards head move : activate
Applications

What we can do…

What we can do…
● Take a picture
● Record a video
● Perform a search on Google
● Request directions and get GPS navigation
● Send a message
● Call a contact
● Participate in a hangout
● Receive notifications (email, Google+, Google Now…)
● Install Glasswares

MyGlass Mobile
● Associate your Google+
account (for example to
synchronize your pictures)
● Connect your Glass to your
mobile using bluetooth (phone
calls, configuration, GPS…)
● Configure Wifi access points
● Add contacts to the Glass
● Activate Glasswares

MyGlass Web

Example: NYT Glassware

Example: CNN Glassware

Demo

Glass Explorer program

Glass Explorer program
● Around 2000 users who registered during Google I/O 2012
● Officially targeted to US developers
● Around 8000 more users selected through the #IfIHadGlass
contest beginning of 2013
● Access to Developer prototype since april 2013
● Access to the Mirror API and related forums
● Presentation event in several places (including Mountain View
campus) to learn how to get started with Glass
● 3 invitations to send to potential new #GlassExplorer in
november

Development prototype

Google Glass v2

New Version
● Headphones to hear correctly in noisy environment
● Allows Prescription Glasses to be mounted
● Newer version of the CPU (OMAP 4430) supposedly increasing
a bit performances
● No plastic glasses
● CE mark on the Glass 
● Original Glass Explorers can exchange their v1 for a v2
● Lightweight titanium frames for Glass with prescription glasses

Version 1 vs Version 2

Programming for Glass

Programming for Glass
● Mirror API : programming server side in Go, Java,
Python, .Net, PHP… (original method)
● GDK (Glass Development Kit) Preview : Android
programming in Java. APK installed directly on the device
● WearScript : Javascript for Google Glass created by
Brandyn White allowing quick and easy prototyping of
application (supports other wearable devices)

Playground

Mirror API vs GDK

Programming with the Mirror API

Mirror API
● Original way to program Google
Glass
● Composed of RESTful services
● No need to execute code on the
Glass
● Calls need to be authenticated
using OAuth 2.0
● Starters projects available in Java,
PHP, Python…

# Insertion into Timeline : Text
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException {
String userId = AuthUtil.getUserId(req);
Credential credential = AuthUtil.newAuthorizationCodeFlow().loadCredential(userId);
...
if (req.getParameter("action").equals("addtext")) {
LOG.fine("Inserting Timeline Item: text");
TimelineItem timelineItem = new TimelineItem();
timelineItem.setText("You've got mail! " + new Date().toString());
timelineItem.setNotification(new NotificationConfig().setLevel("DEFAULT"));
Mirror.Builder mb = new Mirror.Builder(new UrlFetchTransport(), new JacksonFactory(), credential);
Mirror.Timeline timeline = mb.setApplicationName("GlassExplo").build().timeline();
timeline.insert(timelineItem).execute();
}
Servlet receiving the request
Insertion of a Text Card
Request example: http://localhost:8888/main?action=addtext

# WhoIsThat

Programming with the GDK Preview

GDK Developer Preview
● GDK = Glass Development Kit
● Allow to do development in your Android development
environment
● Sneak Peek v1 release on november 19, 2013
● Very preliminary version before the Developer Preview!
● Based on Android 4.0.3
● Simple add-on for Glass specific features (voice
commands, gestures, cards buildup)
● Possibility to develop with NDK (ex. Translation App)

GDK Developer Preview (2)
● Provide access to sensors
● Display preview stream of camera
● Capture pictures and videos
● Capture voice
● Handle trackpad directly
● Display full screen
● Create cards

GDK : Card creation
● A standard card has:
● A main text
● A footer
● One or several images
// Create a card with a full-screen background image.
Card mycard = new Card(context);
mycard.setText("This card has a puppy background image.");
mycard.setFootnote("How can you resist?");
mycard.setImageLayout(Card.ImageLayout.FULL);
mycard.addImage(R.drawable.puppy_bg);
// Don't call this if you're using TimelineManager
View mycardView = mycard.toView();

Programming with WearScript

Programming with WearScript
● One line installer on Linux
curl -L http://goo.gl/nRjW6y > install.py && python install.py
<html style="width:100%; height:100%; overflow:hidden">
<body style="width:100%; height:100%; overflow:hidden; margin:0">
<canvas id="canvas" width="640" height="360" style="display:block"></canvas>
<script>
function server() {
WS.log('Welcome to WearScript'); // Write to Android Log and Playground console
WS.say('Welcome to WearScript'); // Text-to-Speech
WS.sound('SUCCESS')
// Changes canvas color with head rotation
WS.sensorOn('orientation', .15, function (data) {
ctx.fillStyle = 'hsl(' + data['values'][0] + ', 90%, 50%)'
ctx.fillRect(0, 0, 640, 360);
});

“Shazaglass”

Thoughts after 1 year…

● Very interesting concept with LOT of potential
● Prototype light and comfortable
● Allow to keep normal field of vision intact
● Prototype for Developers and Explorers at the moment
● Easy programming with Mirror API but limited
● GDK coming soon (in the meantime sneak peek to developer
preview)
● Monthly updates with new features
● Several thousands developers preparing applications

● Prototype only for Developers and Explorers at the moment
● Battery doesn’t last long enough
● Difficult to hear in noisy environment
● French accent is not always recognized 
● The camera without cache makes some people uncomfortable
● No easy way to secure the Glass when you walk in public areas
● No way to prevent updates (can be scary)
● Not yet available to the Public (sometimes in 2014?)
● Some things we want to do not yet available through APIs

Very interesting concept
with LOT of potential

Glass World

Possible Use Cases
● Facial recognition (Google doesn’t want it for now)
● Secondary screen for gaming
● Recording of places, people… with comments
● Access to medical files during surgery
● Ads/QR Code scanning to get more details about a product or
compare prices
● Control moving devices (drones…)
● Learning by seeing through the eyes of the teacher
● See notes while making a presentation
● …
