The Design and Evaluation of Mobile HCI in Dietary Intake Estimation

This research designs and evaluates app interfaces designed to estimate and record dietary intake. Effect and user's preference are taken for consideration. Three potential interfaces are proposed, i.e., a) interactive photo interface; (b) a sketching interface, and c) a resizable shape interface. Trials with 38 university students indicate that a) and b) both provide some useful features, but there is a preference for the interactive photo interface. Future research will focus on design enhancements to improve user experiences in different target groups.
