smartphone data acquisition and analysis for monitoring food choices

DietSense is an online service that allows you to self-monitor your food choices and further request comments from dietary specialists.  Mobile phones with CENS participatory sensing platform will let you record photographs of your meal everyday, either automatically or by sensible notifications (based on time of the day or location). In addition to photos, you are encouraged to annotate the photos with voice or text messages providing information not captured by the images (e.g. diet soda as opposed to regular soda).  Data (daily photos, timestamp, location via localization techniques or user-reported), and annotations (text/voice) are stored in password-protected accounts on web servers for self-review and specialist assisted analysis. When you log on to your DietSense profile you will see personalized presentation of your dietary habit. Dietary specialists can provide further analysis if you configure your profile to be shared.
