This paper describes the design and initial evaluation of Tag-liatelle, a collaborative tagging application for encouraging healthier eating. Users photograph their own meals and upload these photos to a website, where fellow users anonymously tag them for content. Initial results suggest that tagging of food content is a popular activity. However, further work must be done to automate the extraction of valid nutritional information from the tags generated. Keywords Games for health, image tagging, photographic food diaries, nutrition, ubichomp. ACM Classification Keywords J.3 [Life and medical sciences]: health, H.5.3 [Group and Organization Interfaces]: collaborative computing. General Terms Design, Human Factors, Experimentation.
