Researchers studied how mobile-based food journals integrate into everyday life and specific challenges when using food journaling technology. Their research suggests how future designs might make it easier and more effective.\u003C\/p\u003E\u003Cp\u003EThe research study uncovered three problem areas: barriers to reliable food entry, negative nudges in current food journal apps and challenges in social features. The findings resulted from data collected in a survey of 141 current and former food loggers as well as analysis of 5,526 public posts on the community forums of mobile-based MyFitnessPal, FatSecret and CalorieCount.\u003C\/p\u003E\u003Cp\u003E\u201cCommunity contributions to the databases allow journalers to publish nutritional entries themselves and create a diverse food base from which to pick, but it also raises concerns about reliability,\u201d says Edison Thomaz, a researcher on the study and Ph.D. candidate in Human-Centered Computing at Georgia Tech.\u003C\/p\u003E\u003Cp\u003ESome users said logging meals took too much effort and was time consuming. They sometimes loosely followed recipes or only ate partial portion sizes, making it difficult to log meals. Another issue was that food databases contained inaccuracies, common foods that were missing, or had multiple listings for a single food because of user-generated listings.\u003C\/p\u003E\u003Cp\u003EResearchers found that not all foods are created equal when it comes to logging them. On a seven-point Likert scale, packaged foods and fast food were a breeze to log (6.5 and 6.3 mean scores), while counting up finger foods at a friend\u2019s house or party took dedication (3.2 and 2.9 mean scores).\u003C\/p\u003E\u003Cp\u003EThis made the mobile journals themselves less effective, with some participants straying from their goals or eating the same thing every day to ease the logging ritual. As one respondent put it, it was easier to \u201cscan a code on some processed stuff and be done with it.\u201d\u003C\/p\u003E\u003Cp\u003EParticipants also wanted to develop social connections around food goals. Encouragement of goal attainment and mutual support helped strengthen journaling habits. Conversely, when people received no comments, had online friends stop journaling, or had comparatively less progress than others, it negatively impacted their food-tracking goals.\u003C\/p\u003E\u003Cp\u003EThe findings led to several recommendations, including one for designing goal-specific systems.\u003C\/p\u003E\u003Cp\u003E\u201cFood journals are an important method for tracking food consumption and can support a variety of goals, including weight loss, healthier food choices, detecting deficiencies, identifying allergies and determining foods that trigger other symptoms,\u201d says James Fogarty, a researcher on the study and associate professor of Computer Science \u0026amp; Engineering at the University of Washington.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u201cInstead of attempting to capture the elusive \u2018everything,\u2019 the results suggest creating a diversity of journal designs to support specific goals,\u201d says Fogarty.\u003C\/p\u003E\u003Cp\u003EReputation systems were suggested to allow users to filter for specific needs (e.g. tracking sodium intake) or vote on accuracy of entries. Also a priority: streamlining databases with similar foods and providing context for food entry, such as indicating restaurant items or vegan meals.\u003C\/p\u003E\u003Cp\u003EThe results have also led to separate research by team members to implement new journaling solutions. Georgia Tech researchers are testing the feasibility of using a mobile device\u2019s built-in microphone to capture ambient sounds related to eating that, when recognized by the mobile device, nudge users to log their food. Washington researchers are using photo-based journaling to augment or replace methods focused on detailed nutritional input in an attempt to remove or reduce barriers to journaling.\u003C\/p\u003E\u003Cp\u003EThe research paper \u201cBarriers and Negative Nudges: Exploring Challenges in Food Journaling\u201d will be presented at the ACM Conference on Human Factors in Computing Systems (CHI 2015) in Seoul, South Korea, April 18-23.
