web -> phone

Bring over whole thing

Create subset of UI

Surface functionality via APIs (web services)

Design for smaller screen

Phone -> tablet


Scale it up

Utilize additional space better

phone -> glass


???

Profit

android




Glass


android vs glass: fight!


Display

Battery

Touch

Hello android world


Activity

TextView

Gdk setup

hello glass world


https://github.com/luisdelarosa/HelloGlass

Immersion

Voice Trigger

Theme

Glass Library

GDK vs android sdk


6 new packages

19 new classes

No emulator

Activities + Services play special roles

synergy

“The API surface of GDK Glassware is not limited to the classes contained in the GDK Add-on. The GDK Add-on merely closes the gaps between the Android SDK and features that are unique to Glass. This means, in general, given a problem that isn't covered by the GDK library directly, just attempt the Android solution.”
- Jenny Murphy
Staff Developer Programs Engineer on Google Glass

glanceable ui


Fundamentally different from phone and tablet UI

Less content

Quicker

Bigger

Now

timeline









Immersions exist outside

home card


Voice Launcher

Tap Launcher

Contrast with Home Screen

cards


Like Google Now

Horizontal rather than vertical

Main UI metaphor for Glass

use the templates

static cards


No longer in GDK as of XE 16

Use Mirror API

any questions so far?

'Slow' cards


Remote Views

Why "slow"?

PendingIntent

Code

REMOTE VIEWS

FrameLayout
LinearLayout
RelativeLayout
GridLayout
GridView
ImageView
ListView
ProgressView
StackView
TextView


AdapterViewFlipper
ViewFlipper
AnalogClock
Button
Chronometer
ImageButton

'Fast' cards


View Drawing

Update much quicker

Code

Menus


The same menus you're used to

Code

Questions?

immersions


Repurposed Activity

Full control over Glass hardware

Exist outside of Timeline

Be careful of Glassing-out

project: reddit viewer


List the posts in a subreddit

Common list-based app UI

android version


Activity

Vertical scrolling

Row-based

ListView


glass version


Immersion

Horizontal scrolling / paging of cards

CardScrollAdapter

CardScrollView

https://github.com/luisdelarosa/RedditViewerGlass

alternate android version


Horizontal scrolling / paging

Fragment-based

ViewPager

menus in immersions


Show when tapped

openOptionsMenu()  

Ordinary Android menu methods

onCreateOptionsMenu()
onOptionsItemSelected()
onOptionsMenuClosed() 

touch


Default: D-Pad events

Timeline consumes some for non-Immersions

Swipe down is like Back button

Two finger swipe down is sleep


more touch


GestureDetector

Swipe up/down/left/right + TwoSwipe
Tap / TwoTap / ThreeTap
LongPress / TwoLongPress / ThreeLongPress

Finger count change

Scroll listener
Two finger scroll listener

voice control


Voice Trigger

Voice Prompt

Speech Recognizer

No contextual voice commands yet (Issue http://code.google.com/p/google-glass-api/issues/detail?id=273)

head movement

Unique way to get user input

Not eye tracking

Accelerometer

Unknown ergonomic impact

Built-in Glass gestures

getWindow().addFlags(WindowUtils.FLAG_DISABLE_HEAD_GESTURES); 

location


No Google Play Services yet

Old school Location

Iterate over all providers, including remote (tethered)

sensors


Accelerometer

Gyroscope

Magnetometer

Relative to "optics pod" aka prism

Light

camera


Capture image:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, MY_REQUEST_ID); 
Capture video:
Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
startActivityForResult(intent, MY_REQUEST_ID); 
Can capture hardware button in Immersion
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_CAMERA) {

battery


Video

Sensors

navigation

Driving
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,   Uri.parse("google.navigation:q=your+address"));
startActivity(intent); 
Walking
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,  Uri.parse("google.navigation:q=your+address&mode=w"));
startActivity(intent); 

login flow


QR code

AccountManager

Star this issue: http://code.google.com/p/google-glass-api/issues/detail?id=276

In-Progress

open source libraries


glass-progress-bar

GlassSettings

glass-head-gesture-detector

extras


Alternative input methods

Text Recognition

BroadcastReceivers still exist

Poke Around!
