  • The Future of Mobile Eric Brewer BEARS February 11, 2010 UC Berkeley, BEARS 2010
  • Most Successful Technology Ever
    • 3-4B cellphone users worldwide
      • Vastly outpaces TV, PCs,
    • 1.13 billion phones sold in 2009
      • 36 per second
      • Versus 15 billion shoes per year
      • Versus 0.3 billion PCs
    • 174M were smart phones
      • 15% (up from 12.8% in 2008)
      • Smart phones will pass PCs in the near future
    UC Berkeley, BEARS 2010
  • What’s in an iPhone? UC Berkeley, BEARS 2010
  • What’s in an iPhone (3GS)
    • 600 MHz ARM processor
      • About 1200 MIPS for 300mW
      • 256MB ram, 16 GB flash
      • Roughly a 1999 Pentium III ~ 1350 MIPS for 37W
    • PowerVR graphics core
      • 7M triangles/sec, 250M pixels/sec
    • Mac OS X
      • same as Mac, iPad, iPod Touch
    • Sensors:
      • Camera, mic, GPS, compass, proximity, ambient light, ambient noise, 3D accelerometer, touchscreen, temperature
    • WiFi, GSM, Bluetooth, USB
    UC Berkeley, BEARS 2010
  • What’s in an iPhone? (3GS) UC Berkeley, BEARS 2010
  • Supercomputer
    • “ Access is the Killer App”
      • Access to the cloud >> any device
    • Cellphones are pocket supercomputers
      • Every search
      • Image recognition, object recognition:
        • Red laser
        • Google Goggles
      • Sound recognition: dictation, translation… Shazam
    UC Berkeley, BEARS 2010
  • Replace the PC?
    • Cellphone accessories:
      • Big screen (~200M sold per year)
        • … with wireless access (Wireless USB coming)
      • Keyboard
        • Or just use voice + supercomputer?
      • Extra processing and disk space?
        • Maybe…. Or just use the cloud
        • Likely want local graphics acceleration
        • PC as a cellphone accessory
    • My bet: cellphone wins… maybe it already has
    UC Berkeley, BEARS 2010
  • Developing Regions
    • Cellphones are everywhere
    • Many advantages:
      • Small, portable, with self-contained power
      • Voice works for all languages (but not text)
      • Easy to use, culturally accepted
    • +10% mobile penetration => GDP up 0.8%
      • Causal, not just correlation
      • Greatest development project ever?
    • PCs may not ever get great penetration
    UC Berkeley, BEARS 2010
  • Urban vs. Rural
    • Value of the cellphone limited by coverage
      • Even more true with the Cloud
    • Cellular is an urban phenomenon
      • Rural areas generally left out
      • … basestation costs limit rural deployment
    • This is the real “digital divide”
      • Not between nations
      • … but between urban and rural (even in the US)
    UC Berkeley, BEARS 2010
  • CellScope: Cellphone Microscope
    • Cellphone camera + big lens = microscope
    • Diagnosis:
      • Image recognition on the phone?
      • … in the cloud?
      • … by a remote expert?
    • Clinical quality:
      • Malaria,
      • TB already verified as detectable
    UC Berkeley, BEARS 2010 Dan Fletcher UC Berkeley
  • SmartPhone Diagnostic Device
    • Idea: collection of very simple sensors that connect to the audio jack
      • Easy: heart rate, respiratory rate, temperature
      • Medium: blood oxygen, ECG
      • Hard: blood pressure
    • Goal: much cheaper, easy to use diagnostic device
      • Phone converts raw data into readings
      • Can also forward raw data over GSM
    UC Berkeley, BEARS 2010
  • Conclusion
    • Smart phones =
      • PC + sensors + connectivity + portability
    • Access is the killer app
      • The real win is phone+Cloud
    • Cellphones are transforming development
      • Driving increased quality of life for the poor
      • The first high-tech solution to cross over
    • Rural access must be a priority
