(aff301) fire phone: the dynamic perspective api, under the hood | aws re:invent 2014
DESCRIPTION
Fire phone's Dynamic Perspective adds a whole new dimension to UI and customer interaction, combining dedicated hardware and advanced algorithms to enable real-time head-tracking and 3D effects. This session goes behind the scenes with the Dynamic Perspective team, diving into the unique technical challenges they faced during development. Afterward, we explore the Dynamic Perspective SDK together so you leave the session knowing how to add innovative features like Peek, Tilt, 3D controls, and Parallax to your own apps.TRANSCRIPT

Setting up an event listener

public void onHeadTrackingEvent(HeadTrackingEvent event)
Extract head tracking data
final float x_coor = eventx_mm
final float y_coor = eventy_mm
final float z_coor = eventz_mm
final boolean face = eventisFaceDetected
final boolean tracking = eventisTracking
Polling for data
mHeadTrackingManager = HeadTrackingManagercreateInstance(thisActivity)
mHeadTrackingPoller = mHeadTrackingManagerregisterPoller()
mHeadTrackingEvent = HeadTrackingEventobtain()
mHeadTrackingPollersample(mHeadTrackingEvent)

mFaceDetectedsetText(getString(Rstringfacedetected) +
mHeadTrackingEventisFaceDetected)
mHeadTrackingsetText(getString(Rstringheadtracking) +

Register for GestureEvent (Tilt)
mGestureManager = GestureManagercreateInstance(thisActivity)
mTiltGesture = GesturegetGestureFromId(GestureTILT)
Override
public void onGestureEvent(GestureEvent event)
Move drawer down if it is not already down
if (mDrawerDown)
final TranslateAnimation translate = new TranslateAnimation(0 0 -mDropDownDrawergetHeight() 0)
translatesetDuration(ANIMATE_DURATION)
translatesetFillAfter(true)
mDropDownDrawerstartAnimation(translate)
mDrawerDown = true
Adding auto scrolling to a ListView
private TiltScrollController mTiltScrollController
Override
public void onCreate(Bundle savedInstanceState)
superonCreate(savedInstanceState)
setContentView(Rlayoutmain)
Create an instance of TiltScrollController
mTiltScrollController = new TiltScrollController(this)
Set up ListView and ListAdapter
ListltStringgt cities = readCities()
ListAdapter adapter = new ArrayAdapterltStringgt(this Rlayoutcity_layout Ridcity_name cities)
ListView cityListView = (ListView) findViewById(Ridcity_listview)
cityListViewsetAdapter(adapter)
Attach the ViewGroup and ListView to the TiltScrollController
ViewGroup containerView = (ViewGroup) findViewById(Ridcontainer)
mTiltScrollControllerattach(containerView cityListView)
Add a TouchEventTrigger to the TiltScrollController
This trigger disables tilt scrolling when the view is in a touch event
mTiltScrollControlleraddScrollStateTrigger(new TouchEventTrigger(cityListView))
Add a PanelVisibleTrigger to the TiltScrollController
Disable tilt scrolling when the Center panel is not the currently visible top panel
SidePanelLayout sidePanelLayout = (SidePanelLayout) findViewById(Ridsidepanellayout)
mTiltScrollControlleraddScrollStateTrigger(new PanelVisibleTrigger(sidePanelLayout
PanelVisibleTriggerPanelCenter))

Create an instance of TiltScrollController
mTiltScrollController = new TiltScrollController(this)
Set up ListView and ListAdapter
ListltStringgt cities = readCities()
ListAdapter adapter = new ArrayAdapterltStringgt(this Rlayoutcity_layout Ridcity_name cities)
ListView cityListView = (ListView) findViewById(Ridcity_listview)
cityListViewsetAdapter(adapter)
Attach the ViewGroup and ListView to the TiltScrollController
ViewGroup containerView = (ViewGroup) findViewById(Ridcontainer)
mTiltScrollControllerattach(containerView cityListView)
Add a TouchEventTrigger to the TiltScrollController
This trigger disables tilt scrolling when the view is in a touch event
mTiltScrollControlleraddScrollStateTrigger(new TouchEventTrigger(cityListView))
Add a PanelVisibleTrigger to the TiltScrollController
Disable tilt scrolling when the Center panel is not the currently visible top panel
SidePanelLayout sidePanelLayout = (SidePanelLayout) findViewById(Ridsidepanellayout)
mTiltScrollControlleraddScrollStateTrigger(new PanelVisibleTrigger(sidePanelLayout
PanelVisibleTriggerPanelCenter))
