  1. Compaq Mercury ProjectExploring the Future of Handheld Computing October 18, 2001 Jamey Hicks Jamey.hicks@compaq.com

  2. Outline • Our Vision of Handheld Computing • Open Handhelds Project • Mercury Project (BackPAQ)

  3. Pervasive Handheld Computing • Blackberry – a step in the right direction • Email anywhere • But if we had GB local storage and wireless networks… • All your information • All your apps • Secure storage: safely store credit cards, etc. • Display on a projector in the room • Show headings on wristwatch computer • Show 3D rendering on desktop

  4. Pervasive Computing • Seamless, secure, ubiquitous access to your all your information • Any information • Any time • Any where • Human centered The next generation of computing

  5. Anytime, Anywhere • From any network, on any device • Use best available network • “Best” can be cheapest, fastest, … • “Seamless” • => automatic discovery and configuration of devices, networks, and services • Adaptive • Retrieval, rendering, UI appropriate to device • Nonstop • It has to work all the time

  6. Research Questions: Systems • Automatic administration • Discovery • Configuration • Planning • Distributed storage • Secure, replicated, consistent • Adaptive networking • Agents • Services, microcommerce • …

  7. Outline • Our Vision of Handheld Computing • Open Handhelds Project • Mercury Project (BackPAQ)

  8. Open Handhelds Project • Program for stimulating development of innovative new applications on handhelds (e.g., iPAQ H3600) • Derived from OpenItsy Initiative • Joel Bartlett, Bill Hamburgen (WRL) • http://research.compaq.com/wrl/projects/Itsy/itsy.html • Website (www.handhelds.org) • Hosts source code, binaries, discussion groups • Free technical support • Seed hardware for key developers • Community: 500 entries on email list, active IRC • Timeline • April 2000: Began Linux port to iPAQ H3600 • June 2000: Posted first release of Linux for H3600 on www.handhelds.org

  9. Linux Capabilities • Linux Kernel 2.4.7 (this week) • GNU Software • Complete GUI flexibility • X Window System, Qt, Microwindows • Filesystems • JFFS2: compressed journaling flash filesystem • ext2, vfat, nfs, samba, coda, … • Networking • WLAN, WWAN • IPSEC and other VPN • IPv6, Mobile IP • Java 2 Micro and Standard Editions Not just a zippy PDA, but a pocket workstation

  10. Linux on the iPAQ: Familiar distribution • Python scripting • JFFS2 root • X Window System • Gnome toolkit • Full screen handwriting input • Anti-aliased fonts • Landscape or Portrait mode • Full networking • Distributed as ipkgs [Dbutter@wireless.net]

  11. QPE: Qt Pocket Environment • Uses Familiar as base • without X • distributed as ipkg’s • very polished look • PDA-oriented

  12. Intimate Linux • Marked by close acquaintance, association, or familiarity. See Synonyms at familiar. • Full blown linux on the Compaq iPAQ! • Native development • Stunts: bochs x86 emulator

  13. PocketLinux • XML application framework • Implemented in Java • Runtime: kaffe JVM • Linux OS underneath • Full support for “theming” • Do not follow the 1.0 installation instructions – they can be hazardous to ipaq’s – email jamey for revised instructions if you’re interested in this.

  14. Outline • Our Vision of Handheld Computing • Open Handhelds Project • Mercury Project (BackPAQ)

  15. CRL’s Mercury Project • A research project to extend the boundaries of pervasive wireless computing • Hardware: • A handheld research platform • Software: • Networking, middleware and applications • Based on Linux Kernel and Open Source Software • IPv6 Mobility Exploring the future of handheld computing

  16. Mercury Hardware • Pushing the envelope of integration • BackPAQ: prototyping platform • Extension pack with: • VGA CMOS camera • 32MB Flash, FPGA, • Additional expansion connector, • 2 PC Card slots • Accelerometer • Audio codec and headset connector • WLAN and WWAN via PC Cards

  17. iPAQ H3600/BackPAQ

  18. iPAQ H3600/BackPAQ

  19. BackPAQ Accelerometer Demo • Oneko • Cat and mouse • Mouse runs downhill and cat follows mouse • Screen Rotation • Stand iPAQ/BackPAQ up, on side, upside down • Screen is rotated to match • Window manager receives ResizeAndRotate event • Applications are resized appropriately

  20. BackPAQ Video Conferencing Demo • H.323 audio and video supported • can call Polycom or Netmeeting • H.261 codec is quite slow • www.openh323.org • VIC: videoconferencing tool • Many codecs supported • Multicast and IPv6 also supported • ftp://ftp.ee.lbl.gov/conferencing/vic

  21. Home WLAN or Ethernet Foreign WLAN or GPRS Network IPv6 Node Mobility Architecture IPv6 Router Direct routing from CN to MN on home network MIPv6 (HA) Home Agent A.P. A.P. Mobile Node Sending Video MIPv6 (CN) Correspondent Node Receiving video Communication path Wired connection 802.11b wireless connection

  22. Home WLAN or Ethernet Foreign WLAN or GPRS Network MIPv6 After Node Migration: Forwarding IPv6 Router Mobile Node Sending Video MIPv6 Home Agent A.P. A.P. HA encapsulates and forwards packets to MN on foreign network Correspondent Node Receiving Video Communication path Wired connection 802.11b wireless connection

  23. Home WLAN or Ethernet Foreign WLAN or GPRS Network MIPv6 Architecture: Routing Optimization IPv6 Router MIPv6 (HA) Home Agent Mobile Node Sending Video A.P. A.P. MN sends care-of address to CN, CN sends packets to new location Correspondent Node (CN) Receiving Video Communication path Wired connection 802.11b wireless connection

  24. Mercury Foundations and Collaborations • Foundations • Itsy: • Building on Linux, StrongARM, camera, packaging, ... • Open Handhelds: • Building on Linux on iPAQ H3600 • External Collaborations • MIT (Oxygen Project): • iPAQ/BackPAQ being used as Handy 21 prototype • Reuters (iPRISM): • Demonstrating end-to-end application • CMU (Coda, Intermezzo Filesystems)
