Healthcare researchers wanted to modernize an existing dietary tracking tool by designing a contemporary interface and making it 508 compliant, mobile compatible, and usable on modern browsers.

We took a complex research methodology and made it easy to digest.

The Automated Self-Administered 24-hour Recall (ASA24) is a web-based tool that allows researchers, healthcare professionals, and teachers to collect dietary data for hundreds of research studies. With so many users, it’s essential the interface be as easy-to-use as possible.

In partnership with Westat, we employed an iterative design approach with regular user testing to ensure the project was guided by real-world needs. We targeted a tablet-first layout to allow flexibility within a clinical setting and created alternative interactions to provide a parallel experience for disabled users.

Our process balanced accessibility compliance measures, tablet application development using modern web application frameworks, automated testing and engaging design. The newly released ASA24 is an intuitive web and tablet application that improves data collection, reduces errors, and maintains Section 508-mandated accessibility compliance. ASA24 streamlines the user experience and facilitates accurate data collection for crucial clinical study activities.
