  1. Clinical PDAs : Handheld Technology, Applications, and Practical Implementation in Healthcare Education Robert B. Trelease, Ph.D. Associate Professor and Associate Director, Instructional Design and Technology Unit Dean’s Office, UCLA School of Medicine

  2. Handheld Generations I: • Generation 1: The Apple Newton (RIP 1998) • MessagePad 2000/2100 Specifications: • Size: 1.12" x 4.7" x 8.3". • Weight: 22.4 ounces • Processor/Chip: 160 MHz StrongARM SA-110 RISC • RAM: 5MB (2100 has 8 MB) • ROM: 8MB • Power/Battery: 4 AA alkaline batteries (optional rechargeable) • Screen Type: transflective backlit LCD, Touch Screen Resolution: 100 dpi; Size: 480 by 320 • PCMCIA Slot(s): Two Type II PC Card slots • Ports: Serial, sound I/O

  3. Handheld Generations II: • Generation 2+: Palm (Pilots) and Their Siblings • Size: 0.67 " x 3.17 " x 5.06 " (IIIc) • Weight: 6.8 ounces (IIIc) • Processor/Chip: Motorola 68328(EZ) 16-33 MHz • RAM: 2-8 MB • ROM: 2MB • Power/Battery: 2 AAA alkaline batteries (optional rechargeable) • Screen Type: TFT active matrix, Touch Screen Resolution: 100 dpi; Size: 160 by 160, grayscale or color (to 16 bit) • Expansion Slot(s): SpringBoard, TRG, m505, CLIE • Ports: Serial/USB and IRdA and speaker

  4. Handheld Generations III: • Generation 3+: WinCE (3.1) Pocket PCs • Size: 0.68" x 3.28" x 5.11" (iPAQ bare) • Weight: ~6 ounces • Processors/Chips: 133-206 MHz RISCs • RAM: 16-32 MB • ROM: 16 MB • Power/Battery: rechargeable • Screen Type: TFT active matrix, Touch Screen Resolution: 100 dpi; Size: 240 by 320 • Expansion Slot(s): CF, Expansion Pack (iPAQ) • Ports: Serial/USB and IRdA • Built-in ‘CD-quality stereo (speaker/outputs) and microphone

  5. Serving the King I: Palm OS Capabilities • Text: up to ~20 characters wide by 16 lines • “Handwriting” (Graffiti) entry in silkscreen panel at bottom of screen: No visual feedback and users need to learn special alphabet • Graphics JPEG and GIF with add-on programs (160 x 160 pixel limit*) • Sound: beeps from speaker, primitive WAV player SW, SpringBoard MP3 and recorder modules, no built-in input • Networking with modems, CDPD, ethernet, wireless (with SpringBoard)

  6. Palm OS Capabilities: About Syncing and Networking • PDAs may work as stand-alone devices BUT they are dependent on a networked workstation or laptop for effective use • On HotSyncing, changes and additions to PDA personal information manager data (date book appointments, addresses, memos, mail, and to-do list items) are synchronized with those on the workstation • On HotSyncing, programs to be installed are transferred from PC to PDA • On HotSyncing, Web pages from designated sites are downloaded through the PC to the PDA • All these transfers occur automatically with little or no attention from the PDA user • PDAs can be networked directly through cell modems (CDPD) or special NICs

  7. Palm OS Capabilities II: About Syncing and Networking Syncing can use: • USB/serial port • Infrared (IRdA) port • Network connection (TCP/IP) There is NO direct access to files on the PDA from the syncing computer!

  8. Palm OS Capabilities: About Files and Programs • Program (application) files have a .prc (‘program resource) filename extension on host computers or servers • Program data files have a .pdb (‘program database) filename extension on host computers or servers • All .prc and .pdb files are loaded and installed on Palm OS devices during synchronization • If a program allows, data (.pdbs) can be beamed from one PDA to another via infrared • Except for special developer’s tools, files are generally NOT freely uploadable from PalmOS PDAs to PCs • Special filters and programs can be used to produce .pdb files for Palm OS (e.g., Word PalmDocs filter for producing reader DOC files • Web servers can be used to distribute .prc and .pdb files

  9. Palm OS Capabilities II: Wireless Networking • “cellular modem”: CDPD • Wireless ethernet (IEEE 802.11b or WiFi)

  10. Palm OS Capabilities II: Wireless Networking • Wireless Web connection to remote server (through Apple AirPort)

  11. Serving the King II: Useful Resourcesfor Medical Education • Personal Information Manager (PIM) utilities • PDA-dedicated Web sites (e.g., HandHeldMed) • Programming Environments (CodeWarrior, etc) and the PalmOS Simulator (POSE) • Document Readers (TealDoc, AportisDoc, iSilo, MobiPocket, HandHeldMed Reader, Acrobat!) • Database managers (Jfile, HanDBase) • Web (Clipping) browsers (e.g. AvantGo) • Patient records (PatientTracker, PatientKeeper, 5 Minute Clinical Consult) • Pharmacopeiae (ePocrates qRx, Tarrascon, PDR) • Decision Support (e.g. MedRules) • Reference Books (e.g. Harrison’s)

  12. PDA Resources on the Web • General PDA sites: • PDAstreet: www.pdastreet.com • PalmOS home: www.palmos.com • MS Pocket PC home: www.pocketpc.com • Useful commercial PDA sales sites: • Handango: www.handango.com • MobilePlanet: www.mobileplanet.com • Medical PDA sites: • HandheldMed: www.handheldmed.com • pdaMD: www.pdamd.com

  13. PDA Resources on the Web: HandHeldMed

  14. PDA Resources on the Web: pdaMD

  15. PDA Resources on the Web: PDAStreet

  16. Serving the King II: Useful Resourcesfor Medical Education – Doc Readers Document Readers (use “DOC” PDB files) TealDoc, AportisDoc, iSilo, MobiPocket, HandHeldMed Reader Document can be prepared with standard programs (e.g., Word) and converted to PDBs (e.g., with a Word filter or MakeDocW.exe) DOCs can contain internal links and indexing Some DOC readers multifunction (e.g., iSILO handling HTML) DOC PDBs can be downloaded from Web sites for loading at synchronization

  17. Serving the King II: Useful Resourcesfor Medical Education - Adobe Acrobat

  18. Serving the King II: Useful Resourcesfor Medical Education - AvantGo What is it? Client- and server-side software for downloading and “clipping” content from Web servers AND interacting with online databases through Web Uis. AvantGo can be used with PalmOS, Pocket PCs, and RIM Blackberry 2-way wireless email ‘pager’ devices What’s on the Client side? A streamlined, graphics-capable PDA Web browser (offline AND online) and workstation sync software (“Channels Manager”) that downloads Web pages filtered by the AvantGo Server What’s on the Server side? A modified Apache Web server that maintains a database of user- selected URLs and delivers this selected content to Clients at synchronization

  19. Serving the King II: Useful Resourcesfor Medical Education - AvantGo How do I get AvantGo? The free (“public’) Client software is downloadable from www.avantgo.com. Some PDAs ship with it. Commercial (“Enterprise”) Server and Client software can be purchased from AvantGo What’s kind of content can the public AvantGoClient deliver? Basic text and graphics Web pages, including tables and menus, but NO FRAMES; standard HTML, ASP, and Cold Fusion pages What else is included in the Enterprise AvantGo client? ECMA 2 compatible Javascript capability (ECMA 3 coming), registered SSL key, ability to deliver PDB and PRC files, XML compatibility in next release
