Project Oxygen: A Retrospective
Larry Rudolph
What was it
Lessons
• Human-centric input: inherently ambiguous
• goal is to disambiguate
• chop into pieces with meaning
• Stepford Wives
input --> recog pieces --> reassembly --> output
Lessons
• information must flow across abstraction barriers
• app --> what is expected
n-best approximation --> app
Lessons
• State of the world is “stochastic”
• most of the time, stuff isn’t working correctly
Multi-modes compensate for errors
Lessons• Lots of similarities in diverse fields
• Bayesian inference widely used
• speech, vision, gestures, handwriting, location, congestion control
• Lots of app-specific optimizations
• real engineering work, not easily generalized
“Its all the same, but different”
Lessons
• Location (indoor) is key
• Hard to beat commodity items
• two heads better than one
Things done right (usually by accident)
• No one overall architecture
• No major standardization effort
• Lots of pairwise interactions
• Fewer constraints with state-of-the-art systems
• Professional videos
• very little cheating; real deadlines
Publications in subfield areas -- measurable progress
Version 2.0?
• “Eat our own sausage”
• lots of support staff for internal technology transfer
• speech recognition on every desk
• free-hand sketching --> powerpoint
• comprehension-lite versions
a’la speech builder
Brittleness
• up and running all the time (not just during demos)
• too many publish & subscribe mechanisms
must be able to measure
Scenario’s
• too much emphasis
• for every “wouldn’t it be cool” scenario, there exists a “nightmare” scenario
there is no “cool-meter” or cool-metric
Metric for Success of Oxygen?
• did it change the world? No
did it help the world change? Yes
