AReplica: User-Centered Design of an Augmented Reality Portion Size Estimation Tool for Dietary Intake Assessment

Portion size estimation is an essential component of dietary intake assessment, but people generally struggle with such estimation. Augmented reality methods have been developed to aid in this, but it is unclear how selected features are intended to improve accuracy or create a positive user experience. In this paper, we present a storyboard for a new augmented reality approach, AReplica. We explain why each feature was chosen and list necessary future research.
