• Questions?
Augmented Reality vs Virtual Reality
• Augmented Reality
• computer-generated visual layers atop
an existing reality
• Improve an existing visual scene
• Interact with visual layers and
touchpoints
• Virtual Reality
• Completely new computer-generated
environment
• Full immersion in a scene
• Interact with the full environment
Augmented Reality vs Virtual Reality
• Augmented reality and Virtual reality are inverse
reflections of one in another with what each
technology seeks to accomplish and deliver for the
user.
• Virtual reality offers a digital recreation of a real life
setting, while augmented reality delivers virtual
elements as an overlay to the real world.
• Reality–virtuality_continuum

What is Virtual Reality – Hardware
What is Virtual Reality – Hardware – Optics
What is Virtual Reality – Hardware – Optics
• Optical lenses make it possible to focus on a screen that is very close to your face.
• Try holding your phone really close to your face. Can you see anything?
• It focuses the light from a near eye display onto your eye in a way that makes it clear.
• It greatly magnifies the image from your phone.
• What are the side effects of magnifying images that close to your eye?
• Reduces the total resolution of the user’s display.
• Depending on the display the experience may seem pixelated.
What is Virtual Reality – Hardware – Display
What is Virtual Reality – Hardware – Display
• Right behind the optical lenses sit one or more VR Displays:
• Usually: High resolution, OlED displays that support low persistence features
• Sometimes the Displays are built into the Headset:
• HTC Vive and Oculus Rift
• Displays can be external devices:
• Daydream View, Cardboard, Samsung Gear
• Low Persistence and motion blur:
• Instead of showing a full image, VR will show you parts of an image.
• Reduces motion blur and keeps the image clear as you navigate about.
• Basically, hides the pixels as they change so the user doesn’t see/perceive blur.
What is Virtual Reality – Hardware – Display – Stereoscopic 3D View
What other Hardware is there?
What is Virtual Reality – Hardware – Tracking
• Vital to VR technology:
• The computer must know where the user is in space.
• All VR systems rely on an Inertial Measurement Unit (IMU):
• Enables high speed rotational tracking
• IMU’s cannot tell where an object is in space, only how it is rotated
• Positional Tracking techniques:
• Cameras
• Lasers
• Magnetic Fields
• This is an active field of discussion and research. IE no accepted best practice yet
What is Virtual Reality – Degrees of Freedom (DOF)
• 3 – DOF Tracking:
• Head Rotation Tracking are
accurate
• Pitch / Yaw / Roll
• X, Y and Z axis
• No depth in the room
• 6 – DOF Tracking:
• Head Rotation Tracking are
accurate
• X, Y and Z axis
• Pitch / Yaw / Roll
• And Positions or body movement
around a room
• X, Y and Z axis
• Surge / Heave / Moving Left
or right
What is Virtual Reality – 3 DOF – Inertial Measurement Unit (IMU)
• Inertial Measurement Units
• Really good at quickly and accurately measuring movement
• IMU Hardware -
• Accelerometer
• Gyroscope
• Magnetometer
• Constantly infer where the headset is pointed
• All major 3 - DOF VR systems use some form of IMU
For more information on using
Android Device sensors:
• Contextual Awareness - Android
Summit 2016
• Slides
• Github Project - makingsense
The Daydream platform makes
use of internal Android Device
sensors to determine movement
What is Virtual Reality – 6 DOF – Major Players
• Oculus Rift:
• Tracking System: Constellation
• Infrared LED system in the Headset
• Camera captures the LED light patterns
• Transmits to a computer and transposes the
• images to the headset
• This Model along with an internal IMU
• Calculates the users head position
• HTC Vive:
• Tracking System: Lighthouse
• Infrared Laser system in base stations
• around the room
• IMU Hardware:
• Accelerometer
• Gyroscope
• Magnetometer
• Constantly infer where the headset is pointed
Daydream!
Cardboard versus Daydream
• Cardboard – Inexpensive VR that works
• No device hardware requirements
• phone + headset-only
• Input:
• Uses the device’s magnetometer to
register the movement of
the included magnet as a click
• 20% Google Project - $15
• Daydream – Virtual Reality for Grownups
• Strict device hardware requirements
• phone + headset + controller
• Input:
• Controller IMU sensor data
• Click events
• Still relatively inexpensive - $79

Developing – Publishing Daydream apps
• Daydream App Quality Requirements:
• “To ensure a great user experience, apps for Daydream must follow specific
requirements for performance and usability”.
• https://developers.google.com/vr/distribute/daydream/app-quality
1. Design Requirements:
• UX-D1 – Users can focus on objects and read necessary text.
• UX-C1 – Controller must be used as a laser pointer when clicking on UI targets.
2. Functionality requirements:
• FN-M1 – App manifest does not request the NFC permission.
• FN-S2 – App uses Daydream API calls to transition between activities.
3. Performance and stability requirements:
• PS-P3 – App does not display a thermal warning during 30 minutes of usage.
4. Publishing requirements:
• PB-P2 – App has a VR Icon.
Developing – Challenges
• Simulator Sickness (Also called Cybersickness):
• Can make people uncomfortable
• Sick, headaches or nauseous
• Anything that causes a mismatch sense of motion can do this
• "Screen door" effect:
• When users look at the display in their VR headset, they will often see a regular
grid of lines. These are the spaces between the pixels, which you can only see
because the screen is magnified and several inches away from your face.
• Requires a Headset, Display (and perhaps a controller) of some sort:
• Barrier to adoption
Developing – Daydream’s Future
• Google Assistant integration:
• Very natural Fit
• Use Voice integration when users cannot physically touch their device
• Multi Controller:
• Why not?
• A users offhand is just sitting there doing nothing
• iPhone support:
• Would require an SDK of some sort
• Not sure if possible in Daydream’s current form
• iOS provides much less Bluetooth control/customization
• Hack it together:
• https://www.techworm.net/2016/12/somebody-just-hacked-google-

  • 16. What is Virtual Reality – Hardware
  • 17. What is Virtual Reality – Hardware – Optics
  • 18. What is Virtual Reality – Hardware – Optics • Optical lenses make it possible to focus on a screen that is very close to your face. • Try holding your phone really close to your face. Can you see anything? • It focuses the light from a near eye display onto your eye in a way that makes it clear. • It greatly magnifies the image from your phone. • What are the side effects of magnifying images that close to your eye? • Reduces the total resolution of the user’s display. • Depending on the display the experience may seem pixelated.
  • 19. What is Virtual Reality – Hardware – Display
  • 20. What is Virtual Reality – Hardware – Display • Right behind the optical lenses sit one or more VR Displays: • Usually: High resolution, OlED displays that support low persistence features • Sometimes the Displays are built into the Headset: • HTC Vive and Oculus Rift • Displays can be external devices: • Daydream View, Cardboard, Samsung Gear • Low Persistence and motion blur: • Instead of showing a full image, VR will show you parts of an image. • Reduces motion blur and keeps the image clear as you navigate about. • Basically, hides the pixels as they change so the user doesn’t see/perceive blur.
  • 21. What is Virtual Reality – Hardware – Display – Stereoscopic 3D View What other Hardware is there?
  • 22. What is Virtual Reality – Hardware – Tracking • Vital to VR technology: • The computer must know where the user is in space. • All VR systems rely on an Inertial Measurement Unit (IMU): • Enables high speed rotational tracking • IMU’s cannot tell where an object is in space, only how it is rotated • Positional Tracking techniques: • Cameras • Lasers • Magnetic Fields • This is an active field of discussion and research. IE no accepted best practice yet
  • 23. What is Virtual Reality – Degrees of Freedom (DOF) • 3 – DOF Tracking: • Head Rotation Tracking are accurate • Pitch / Yaw / Roll • X, Y and Z axis • No depth in the room • 6 – DOF Tracking: • Head Rotation Tracking are accurate • X, Y and Z axis • Pitch / Yaw / Roll • And Positions or body movement around a room • X, Y and Z axis • Surge / Heave / Moving Left or right
  • 24. What is Virtual Reality – 3 DOF – Inertial Measurement Unit (IMU) • Inertial Measurement Units • Really good at quickly and accurately measuring movement • IMU Hardware - • Accelerometer • Gyroscope • Magnetometer • Constantly infer where the headset is pointed • All major 3 - DOF VR systems use some form of IMU For more information on using Android Device sensors: • Contextual Awareness - Android Summit 2016 • Slides • Github Project - makingsense The Daydream platform makes use of internal Android Device sensors to determine movement
  • 25. What is Virtual Reality – 6 DOF – Major Players • Oculus Rift: • Tracking System: Constellation • Infrared LED system in the Headset • Camera captures the LED light patterns • Transmits to a computer and transposes the • images to the headset • This Model along with an internal IMU • Calculates the users head position • HTC Vive: • Tracking System: Lighthouse • Infrared Laser system in base stations • around the room • IMU Hardware: • Accelerometer • Gyroscope • Magnetometer • Constantly infer where the headset is pointed
  • 27. Cardboard versus Daydream • Cardboard – Inexpensive VR that works • No device hardware requirements • phone + headset-only • Input: • Uses the device’s magnetometer to register the movement of the included magnet as a click • 20% Google Project - $15 • Daydream – Virtual Reality for Grownups • Strict device hardware requirements • phone + headset + controller • Input: • Controller IMU sensor data • Click events • Still relatively inexpensive - $79
  • 29. Daydream Hardware – Device Hardware Requirements • Device Hardware Requirements: • Android 7.0 Compatibility Definitions Document • Hardware Requirements Highlights: • Bluetooth 4.2 LE • Display between 4.7 and 6 inches • Resolution at least 1080p @ 60Hz display with • 3ms or less latency and 5ms or less persistence. • (Quad HD or higher recommended.) • OpenGL ES 3.2 and Vulkan • Able to decode 2 instances of 60fps video simultaneously • Consistent 60fps rendering • Temperature sensors capable of reading device surface temperature
  • 30. Daydream Hardware – Headset Requirements • Headset Requirements: • Lenses • Location to strap in a device that is 4.7 to 6.0 inches • Strap of some sort to hold the device place • Near Field Communication Chip • For automatically launching the VR experience • Daydream View: • Has no electronic components, so feel free to wash it
  • 31. Daydream Hardware – Controller Requirements • Controller Requirements: • Sensor Hardware: • 3-DOF - Motion-sensing capabilities • Must include its own IMU • Accelerometer • Gyroscope • Orientation • Touchpad (Clickable) • Will send click events to device • Single click and Long press • Buttons: • Volume Buttons • App Button – Open to developer • Home Button • System functions • long-press to re-center the headset • 3D Pointer: Touchpad App Button Home Button Volume Buttons
  • 32. Daydream Hardware – Controller Emulator • Controller Emulator App: • Most Mobile Phones have the correct hardware to act as a Daydream Controller • Download the Daydream Controller App • Pair your headset phone to your controller phone via Bluetooth • Configure the Controller Emulator device through Developer Options • Documentation • Off you go! Touchpad App Button Home Button Volume Buttons Double tap to emulate a click

Editor's Notes

  1. Hello everyone, I am Jared Sheehan, I am a Lead engineer at Capital One. This talk will be an Introduction to VR with a focus on the Daydream platform. A little about me, I have been building Android applications and devices since 2010 and this is my third DevFest DC presentation (woohoo! Thank you Chida!). In fact I found out about it because I got an email from one of my coworkers that said congratulations on being accepted to DevFestDC this year! Your on the speaker website. In addition, I am a cofounder and organizer of the DCAndroid meetup group, we have regular monthly meetings to nerd out on Androidy topics. You will see our new logo, thanks to Felica Wang (who is still not on Twitter for some odd reason). If you want some stickers please come see me afterwards. Woohoo swag! I know that got you pumped! We have a brand new logo, which you can see right there. If you want a sticker come see me or tweet me afterwards. This presentation will be on slideshare after the session.
  2. Be there or be square.
  3. Be there or be square.
  4. This presentation will be an introduction to Virtual Reality with a heavy emphasis on the Daydream platform, because well, I am an Android Dev. This really is an introduction to VR and Daydream. As such, unlike most of my presentations, I will not show much, if any, code, though I may perhaps in other VR subsequent presentations. My thought process around this is really simple. I didn’t really know what VR was when it came out. It is very different then your standard android application that uses standard Views, Activities, fragments, intents, datastores etc. Its almost all about the visual experience and the user’s immersion and interaction with that environment. Augmented Reality vs Virtual Reality – What’s the difference between the two VR Use cases – Why does VR matter and what makes it interesting What is Virtual Reality – What exactly is it? What is a display, what are the optics, what does 3DOF and 6DOF mean? VR Options – Is Daydream the only VR option out there? Hint: No Daydream hardware – What makes Daydream, daydream and not say… cardboard How it works – A bit on how it works Developing – If you wanted to build daydream applications, what do you need to do? Is it hard? Seems hard… Questions?
  5. AR - is a technology that layers computer-generated enhancements atop an existing reality in order to make it more meaningful through the ability to interact with it. AR is developed into apps and used on mobile devices to blend digital components into the real world in such a way that they enhance one another, but can also be told apart easily. (Now describe the scene) VR – an artificial, computer-generated simulation or recreation of a real life environment or situation. It immerses the user by making them feel like they are experiencing the simulated reality firsthand, primarily by stimulating their vision and hearing. (Now describe the scene)
  6. The virtuality continuum is a continuous scale ranging between the completely virtual, a virtuality, and the completely real, reality. AR use cases – It is used to display score overlays on telecasted sports games and pop out 3D emails, photos or text messages on mobile devices. Leaders of the tech industry are also using AR to do amazing and revolutionary things with holograms and motion activated commands. VR use cases - To create and enhance an imaginary reality for gaming, entertainment, and play (Such as video and computer games, or 3D movies, head mounted display). To enhance training for real life environments by creating a simulation of reality where people can practice beforehand (Such as flight simulators for pilots).

  10. Google launched Jump, a platform for VR video, back at its developer conference in May -- along with a slightly bonkers camera rig called Odyssey co-designed with GoPro. Today, prospective content creators can put their name down to get early access to the hardware (pictured after the break), which GoPro tells us is only available in limited quantity. Google already did something similar, but this time the scheme appears to be specifically aimed at professional partners. We also get to know a little bit more about the rig, including its cost: an eye-watering (at least for us amateurs) $15,000. What do you get for your money? Well, 16 GoPros for starters (that accounts for $8,000 of the Odyssey's cost at the camera's $500 retail price). The rest of the package includes connectivity mounts ("bacpacs") for each camera, cables, memory cards, a pelican case and (of course) the cylindrical Odyssey rig itself. Once combined, the rig will shoot 2.7K video in 4:3 aspect ratio. It is, of course, all about the 360-degree/3D experience, and Google with GoPro hopes that Odyssey can raise the bar in terms of immersive video quality.
  11. Fox Sports VR App - produce a live VR stream of the game loaded with new features: the ability to rewind the game in 30-second increments (for iOS users only), the ability to control replays from different camera angles, live-stats integration, and a suite of highlights allowing easy access to on-demand content. Users will also have the ability to select their own camera angles, picking where they “sit” throughout the game.

  15. A standard 360 video is a flat equirectangular spherical video similar to viewing the world map on a globe. If viewed using VR Headsets, it feels as if you are inside the globe and looking at the inner surface.

  18. In virtual reality, "the brain is expecting everything to be in sync, but things are not always in sync," he said; the virtual world is "incomplete."
  19. Notice the phone displaying a stereoscopic view Stereoscopy, sometimes called stereoscopic imaging, is a technique used to enable a three-dimensional effect, adding an illusion of depth to a flat image. Stereopsis, commonly (if imprecisely) known as depth perception, is the visual perception of differential distances among objects in one's line of sight.
  20. It is the act of reducing/erasing motion blur, allowing the player to move their head and keep eyes fixed on one point, as humans do in reality
  21. Stereoscopic 3D can add another level of immersion by adding depth data between the foreground and background. Your favorite 3D blockbuster films are typically shot with 2 lenses side by side, to give you a feeling of a different vantage point per eye. Like any production, this can look strange if poorly implemented, or absolutely amazing if done right. Stereoscopic 3D in VR, that depth information has to be overlaid and mapped to sphere. Because of parallax between cameras, this can be especially challenging. Any minor flaws or “stitch seams” in the footage are magnified in 3D, and sometimes anomalies occur in different places per eye - which makes it uncomfortable to watch.
  22. 3-DOF detects rotational movement around the X, Y, and Z axis — the orientation. For head movements, that means being able to yaw, pitch, and roll your head (figure above), while keeping the rest of your body in the same location. 3-DOF in VR allows you to look around the virtual world from fixed points —think of a camera on a tripod. For many 360° spherical videos, 3-DOF will provide very immersive content, such as viewing sporting events from a particular seat or nature from a particular lookout point. 6-DOF detects rotational movement and translational movement — the orientation and position. This means that your body can now move from fixed viewpoints in the virtual world in the X, Y, and Z direction. 6-DOF in VR is very beneficial for experiences like gaming, where you can move freely in the virtual world and look around corners. However, even simple things, like looking at objects on a desk or shifting your head side-to-side can be compelling with 6-DOF. 6-DOF is more immersive since it captures our real movement and removes the sensory conflict between our vision and vestibular system (ear - motion, equilibrium, and spatial orientation).
  23. Constellation - The system gets its name from a slew of infrared lights placed at strategic locations on both the Oculus Rift headset and the Oculus Touch controllers. These markers — laid out almost like a constellation — are picked up by the Oculus Sensors, which are designed to detect the light of the markers frame by frame. These frames are then processed by Oculus software on your computer to determine where in space you’re supposed to be.
  24. Uses NFC to auto launch into ”VR Mode” Has Physical Alignment Dots to determine where your phone is, even if it’s a bit off it will automatic calibrations to get the display aligned. https://www.youtube.com/watch?v=ufFQXnIZpJY
  25. The controller is where a lot of the magic of Daydream comes in Controllers should be Accessible, Expressive and Portable. Volume buttons – You don’t have to awkwardly try to press the volume buttons on your device.. Clickable touchpad – All sorts of interesting things App Button – Developer can do whatever they like. Home button – Some system functions like long-press to re-center the headset and (shockingly) go home
  26. It is significantly cheaper and easier to use an extra device to emulate the contoller.
  27. App talks to SDK, which talks to Google VR Services witch handles all the BLE stuff
  28. Unity and Unreal Engine are multiplatform game development platforms
  29. Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. Advanced users employ Blender’s API for Python scripting to customize the application and write specialized tools; often these are included in Blender’s future releases. Blender is well suited to individuals and small studios who benefit from its unified pipeline and responsive development process.
  30. Unity – - Unity is a cross-platform game engine developed by Unity Technologies and used to develop video games for PC, consoles, mobile devices and websites - You can create any 2D or 3D game with Unity. You can make it with ease, you can make it highly-optimized and beautiful, and you can deploy it with a click to more platforms than you have fingers and toes. What’s more, you can use Unity’s integrated services to speed up your development process, optimize your game, connect with an audience, and achieve success.
  31. - Enables Daydream and Cardboard app development in Unity. - Google partnered with Unity to ensure that Daydream was natively supported on Unity (from Day One) starting with Unity 5.6 - Google VR for Unity SDK – Native support for 360 video and input utils - The Google VR SDK for Unity provides additional features like spatialized audio, Daydream controller support, utilities and samples.
  32. Daydream Home is launched as soon as a user puts on the goggles Discovery Window – Curated content that a user can select from Google Play – The full power of Google Play Payments Discoverability 190+ countries Consistency Distribution Daydream – In app purchasing on launch Analytics experience
  33. Virtual reality sickness occurs when exposure to a virtual environment causes symptoms that are similar to motion sickness symptoms.[1] The most common symptoms are general discomfort, headache, stomach awareness, nausea, vomiting, pallor, sweating, fatigue, drowsiness, disorientation, and apathy
