PRESENTATION OUTLINE
Motorcycle Maintenance
- Not about motorcycles
- I know nothing about motorcycles anyway
- Toy at end
- Goals: learn how AR can help, history of AR dev
Easy Rider
- Most famous motorcycle movie of all time
- Keyword is "freedom"
IKEA guy
- You may recognize this fellow
- Cool, smart, born in Sweden
- Very helpful
- But 2D
How To
- Big problem is instructions are in 2D
Guy w/manual
- You constantly break off - Attention switching time consuming
- Software industry sees constant innovation
- Manual tech lags for workers
Car Engine
- Where is the oil dipstick
- User manual doesn't always help
- Sometimes ask: if only there was 3D help in the real world
An idea is born
- First head mounted display invented in 1968
- Tom Caudell "augmented reality" research paper
- Schematic diagrams for Boeing aircraft electricians
- Interaction of superimposed graphics, audio, etc.over a real-world environment in real time
- Stationary vs. mobile
- Mobile = Freedom
Shakespeare
- Missing: other 4 human senses (smell, touch, taste,hear)
- AR is augmentation of senses
- Audio, haptic for blind
- Important: talking about AR not VR
- Other shortcoming: processing not static
Eyes
- Can't blame 'em
- In this presentation we'll be discussing mobile AR systems for visual guidance
- Not discussing marketing apps (eg marker in mags)
Dumbell
- Weight and form factors weren't realistic
- Needed to add weight to reach acceptable functionality
- Development of useful prototypes very slow
- Not even talking about other prohibitive factors like cost
Weight examples
- First pic: 1968 invention (Sutherland)
- Second: 1st mobile AR system by Steve Feiner 1997 - includes GPS!
- Professor of CS at Columbia University
- Can appreciate the decades of research that's gotten us here
- Recon Jet next slide developed for skiiers
- Weight another reason why companies still use iPads/tablets for prototyping
Rabbit
- Getting into AR itself, how does the magic happen? How do these glasses both recognize objects and display graphics in your field of view?
- Mobile AR systems have a few main elements
Moverio
- Epson also makes smartglasses
- Front-facing camera, motion sensors, binocular vision (dual display), 23 deg field of view, LCD based projection lens system
- Gyroscope, accelerometer, compass in headset for head motion tracking
- Handheld controller unit (Android), wifi, GPS, bluetooth, dolby surround sound, battery 6 hours
- Compare with Google Glass!
- AR tech not limited to glasses-can also use smartphone or tablet
Tracking
- Pose estimation in 3D space: distance, direction, orientation of camera in relation to object - normally need a trigger!
- Helps to have 2d flat marker
- Markerless: natural feature tracking such as edges & shapes
- SLAM - environment mapping
- Computer vision hot research topic
Display
- Virtual (2d & 3d) objects are rendered for display in the camera view
- Objects might be specially created for the AR experience, or derive from 3D CAD models; but they must be compressed
- Browser technology used to place virtual objects
- Company here is Aero Glass: air corriders
- Virtual objects either on local device or accessed via network
- constraints: needs better resolution and bright binocular support, example subtitles same color as background
USE CASES
- Limited by our imaginations
- We could distill some common principles in AR
Guide
- AR guides workers step-by-step
- Ideal for complicated actions that robots can't do, such as wiring
- Eg here: Assembly, field service, warehouse picking
- Important for loading vans according to route and weight
Decision Support
- Tagging information to environment
- Also good for all use cases
Collaboration
- Like having a remote expert looking over shoulder
- Good for all use cases, and for training
Become expert
- Case can be made AR can make you an expert in anything?
- Within limits of couse
- Leap forward
