Evaluation of a web-based self-learning system for lifestyle improvement

In this study we examine the web-based “Self-learning System for Preventing Lifestyle-related Disease” currently being developed by the National Institute of Health and Nutrition in order to determine areas for improvement, making the system easier to use. College students of the national registered dietitian training course adopted the roles of learners and supporters in the system and we analyzed their system use history and obtained feedback concerning system use via a questionnaire. There were many requests for the ability to use the system through a mobile phone. Moreover, it became clear that the data input methods involving, for example, calorie acquisition, need to be simplified.
