Obesity is a growing health concern in many parts of the world1) and dietary control has received considerable attention in the healthcare field. However, most dietary control programs require users to manually record detailed information on all meals. This is a tedious task for an ordinary person, which can be a deterrent to taking part in such programs. With the widespread use of digital cameras and smartphones, people now have easy access to a camera during most of their daily activities. They can therefore use photographs of their meals as a record of dietary intake. In addition, images contain much richer information about the meals than textual or tabular descriptions. A recent study showed that merely taking a photo of a meal before eating it could encourage weight loss2). Therefore, images are highly promising candidates for the rapid and easy recording of dietary information. However, although important, ease of recording dietary information is not always sufficient for effective dietary management. A participant in a dietary program regularly meets a consultant, who analyzes the collected data and gives recommendations based on them. If this step were made more frequent, but at the same time less costly and time-consuming, the results would be greatly improved. In the light of these observations, we proposed and launched FoodLog3)4), a web-based multimedia application that can assist an ordinary person to record and manage his/her dietary activities with minimal effort. Instead of creating a detailed record of each meal, the user simply takes a photograph, using a digital camera or a smartphone. The application uses image analysis to detect images of meals in the user' s personal multimedia archive, eliminating the need for the user to select and upload them. Further image analysis estimates the nutritional composition of the meals, and records the results in a database. The user can access the images and the results on the web in a variety of formats, can revise the information if the image analysis was erroneous, and can add extra information where relevant. In this paper, we first describe the state of food record keeping, which usually involves paper-based forms issued by healthcare services. We then present FoodLog, an application that allows users to keep photo-based visual records of their meals, thereby creating and maintaining a food log. We also describe works related to food-related information processing. FoodLog was originally a web-based application that has since been applied to several smartphone applications (apps), which we describe. We also introduce our recent work on extensions to FoodLog. Our aim in this paper is to outline FoodLog and its applications, rather than to discuss its technical details. In addition to its original function, FoodLog can be applied to a diverse range of applications. We describe an example of FoodLog being used to generate donations that fund school lunches for impoverished children in Abstract We have been developing FoodLog, a multimedia system that enables users to maintain a record of their food intake simply by taking photos of their meals. In this paper, we describe the functions and various applications of FoodLog, rather than its technical details. FoodLog is beneficial not only for monitoring food intake but also for several other purposes. During the research and development of FoodLog and in collaboration with a nonprofit organization, we employed it to generate donations for children in African countries. We also outline some extensions to FoodLog that are currently under development.
