UC Berkeley CS160 Spring 2013 User Interface Design mSpray Annie Shin Brent Batas Daniel Wu Jeff Butler Helping the fight against malaria in South Africa Problem Malaria is rapidly growing resistant to traditional pesticides. To combat this endemic, South African governments are spraying DDT, a harmful, persistent chemical banned in the US. In order to find a safer alternative, researchers need data on chemical sprayings, but this data is very difficult to obtain. Target Users Workers in Limpopo, South Africa will use mSpray while spraying homes with DDT, Fendona, or K-Othrine. Data collected by mSpray will be studied by researchers and also used by government officials to keep track of work done by employees (payment purposes). To identify themselves, users hold up their identification badge, which has an RFID, to the back of the Android phone. Solution mSpray logs the frequency and area distribution of anti-malarial spraying, and sends this data to the cloud. This provides researchers with unprecedented data which they can use to evaluate the effectiveness and safety of chemical sprays. This will also help prevent greater outbreaks of malaria by more effectively assigning future spray locations. Design Evolution mSpray’s design changed over time to break down the cultural and language barrier between application and users. We designed our app to be as simple, clear, and error-proof as possible with culturally relevant pictures, large, colorful buttons, and a linear path through the app. Screenshots of our application: (a) Screen to begin reporting a new spray, (b) Screen to enter data regarding a spray, (c) Confirmation screen Final Prototype After users go through the app by answering questions regarding their spraying at a particular location (coordinates recorded by GPS), mSpray automatically fills out government forms and uploads them to the cloud. Authorized people may view the data from a Google spreadsheet and see a map with pins dropped at spray locations. Map display of sprayings recorded by mSpray. Google spreadsheet containing data from recent sprayings. Each row is a spray at a certain GPS location, and each column contains different information (such as number of rooms sprayed).
