1. Stage 1 Development Stage 2 Development Why? • Perform a user study to populate the database with test entries • Populating the database with entries from patients with dietary restrictions or food allergies • Encourage the public to become active in the populating the database • Develop the software for updating and accessing the database • Create a user-friendly web site for accessing information in the database and for uploading new entries • Create a PDA program that works with a barcode reader to facilitate data entry • There is no publicly available database that links UPC codes to nutrition information such as that found on a nutrition label • Users may have varying dietary restrictions • Doctors may want to monitor patients restrictions • Users may have varying food allergies What Open Source Means? Development of an open-source UPC/Nutrition Database with a handheld device Christina M. Lirot, Diane E. Cessna, and Kay H. Connelly Computer Science Department, Indiana University Bloomington, Indiana 47405 Why? What? How? Abstract We are developing an open-source, publicly-available database that connects UPC codes to nutritional information. The main hurdle in this project is seeding the database with information. Our approach will be to populate the database enough to show its usefulness, and then call upon the help of populations that would benefit from access to such a resource (i.e. people with allergies or other dietary restrictions). We are in the first stage of the project developing the software for updating and accessing the database. The software consists of two components: 1. a user-friendly web site for accessing information in the database and for uploading new entries and 2. a PDA program that works with a barcode reader to facilitate data entry. The second stage will consist of populating the database with entries. Like many of the open-source projects, it is our hope that the public will become actively involved in this project once they see how it can benefit them (e.g. help people with allergies avoid certain foods often overlooked in processing). What we are doing now? We recently examined the user interface and have decided to complete the coding for a interactive user study. The user study will take place at the end of February we will make changes to the interface design as they use the application. We are extracting words based on nutritional facts, ingredients and foods to populate the pop-up lists in the interface. We believe that this will help with misspellings that can occur with long unknown words. We are in the beginning of phase 1 of the web service application. ? Future Work • Start programming for web services • Designing the interface for the web • Refining the PDA interface • Populate database with realistic data from users • Conduct another user study to re-test interface on PDA • The software can be freely given away or sold • The source code must either be included or freely obtainable • Redistribution of modifications must be allowed What we are doing now?
