Useful Resources for Medical Education and Clinical Development
  • 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)

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

Did We Have to Program PDA Applications from Scratch?
  • Processor code crafting (e.g., C with CodeWarrior) takes plenty of time AND it would tend to be fairly platform specific
  • Code crafting also takes considerable lead time, SO
  • Wasn’t there any way to take advantage of existing Web development expertise AND repurpose existing Web content for more portable use on PDAs?
  • Could essentially the same content be used for different types of PDAs (e.g., Palm OS and Pocket PC)?

  • Could essentially the same content be used for different types of PDAs (e.g., Palm OS and Pocket PC)? YES!
  • AvantGo was an answer.

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

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

what next
What Next?
  • Pocket PCs push Palm OS PDA manufacturers to enhance device capabilities
  • Increasing power and capability of handheld devices
  • Convergence of Phone, Page, and PIM technologies
  • Wearable computer technology evolves
  • Enhanced display technologies (e.g., ocular displays)
  • More flexible high-speed networking
