1. Design Team Stuart Bartow Raef Haggag Mara Hemminger Chase Ighani Daniel Lidor Asthma Management System

2. Introduction Goals for AccuLung System –Provide a mobile resource for tracking asthma symptoms and history. –Provide a graphical view of user’s asthma history. –Track environmental conditions related to asthma triggers. –Help prevent imminent asthma attacks.

3. Application Requirements PDA with color display Wireless capabilities Digital Peak Flow Meter with IR port

4. Project Tour

5. Usability Procedure Users: 4 asthmatics and 5 non-asthmatics Tasks: Set up a patient profile Record data from a Peak Expiratory Flow test Check recent test result trends – graph results - compare View current environmental conditions – Pollen Count – Temperature – Humidity – Air Quality Index Save History, medications list and other information

6. Usability Findings Graph too difficult to read Environment button not easy to locate Enter Manually button crashes if no data is entered Color choice – buttons and environment readings – to give meaning Add ‘personal best’ to graph Move/Add ‘export’ button to graph page

7. Future Plans More robust graphing capabilities. –Environmental Triggers –Medications Multiple user tracking Record asthma triggers Develop physician version
