A Study on Nutrition and Calorie Trackers

A complete redesign cycle on a mobile “fitness tracker” / “personal health informatics” app: evaluation of existing app, analysis of data and extraction of requirements, conceptual redesign, construction of an interactive prototype, and evaluation. This is a project I did for my Meaning and Form in Human-Computer Interaction class at IUPUI.

Some project deliverables I produced:

An affinity diagram constructed on the basis
of data collected from the user study

An interactive prototype of the
redesigned app (created in Axure).

A User Environment Design (UED)
diagram for the app redesign

The final project report
