1 START By: Mamello Thinyane Thursday, 20 th March, 2003 Supervisor: Greg Foster 00:00 BSc Hons – Rhodes University Project Proposal for:

2 PAW Overview  Problem Statement  Introducing PAW  Aims of the project  Literature review  Implementation

3 Problem Statement “The role of information technology is to empower people with applications, communication, and information. Mobile information technology extends these services to make them more broadly and easily accessible” (microsoft.com) PAW

4 Problem Statement “Demand for information technology remains high within the medical technology community. The Internet is rapidly emerging as the de facto medical information-sharing standard among healthcare providers, patients, and payers” (Canon Communications) PAW

5 Problem Statement Medical industry information needs information sharing e.g. patient monitoring and laboratory accurate and up-to-date information just-in-time information delivery e.g. for operations etc accessibilty – remote, flexible etc current usage of information technology in the medical industry is mostly based on wired networks PAW

6 Problem Statement Solutions provided by mobile information technology remote access flexibility – access from a variety of devices timely information delivery information when and where it is needed Distributed workforce - doctors Increased responsiveness to patient needs PAW

7 PAW ( PatientAnyWhere) Introducing PAW PAW = PatientAnyWhere system Description A wireless patient records system that allows a doctor to access patient records remotely using any appropriately configured mobile device.

8 PAW ( PatientAnyWhere) Aims of the project To design and implement PAW Device independence Robust Fast information access Flexibility

9 PAW ( PatientAnyWhere) Aims of the project – PAW phone interface

10 PAW ( PatientAnyWhere) Aims of the project - PAW

11 PAW ( PatientAnyWhere) Aims of the project To produce a thorough write-up on design considerations rendering content on different devices usability issues ease of data entry ease of navigation implementation issues developing for fast information download intergrating available technologies etc,

12 PAW ( PatientAnyWhere) Literature review

13 PAW ( PatientAnyWhere) Implementation : Challenges Devices need different markup languages, e.g. HTML for PDAs, WML for WAP cell phones, and cHTML for i-mode phones. Different factors to consider, e.g. varying numbers of display lines, screen orientation, and color/black and white displays. Different network connectivity, ranging from 9.6 KB cellular connections to 11 MB Wireless LANs. Different capabilities. Some devices can display images, some can make phone calls

14 PAW ( PatientAnyWhere) Implementation Development technologies IIS VisualStudio.NET VisualBasic.NET ASP.NET ADO.NET MMIT Openwave emulators

15 PAW ( PatientAnyWhere) Implementation Why MMIT reduces the challenge of developing and maintaining web application geared at specific web browsers ASP.NET server controls automatically render the appropriate markup language i.e. HTML, WML, cHTML ASP.NET takes into consideratioin screen sizes and device capabilities when rendering web content Additional device support can be added using MMIT extensibility features

16 PAW ( PatientAnyWhere) Implementation IIS VisualStudio.NET VisualBasic.NET ASP.NET ADO.NET MMIT Openwave emulators PatientAnyWhere

17 PAW ( PatientAnyWhere) Implementation System Architecture

18 PAW ( PatientAnyWhere) Implementation Install required development tools IIS, VisualStudio.NET, MMIT, device emulators etc Determine data requirements – use case modeling Review screen design considerations Design and model user interface – screen flow diagrams, etc Develop the middle tier, business logic Develop the data objects Test, Retest and Optimize Deploy

19 PAW ( PatientAnyWhere) Extensions Implement PAW using JAVA technology J2EE server, JSP, JAVA Beans, etc Extend the system to a larger context eg provincial or national level Review design considerations issues of concurrency, security, data synchonization Commercial cellular network service provider Intergrate a GPS functionality into PAW ie the ability to view lists of patients within a doctor’s location

20 END That’s PAW for you… Any Questions? Thank you very much!!!
