System and Method for Assessing Diet Quality Via Photo Navigation Using Dietary Fingerprints

A method for image-based dietary assessment via a mobile application, the method comprising:

• receiving, via a mobile application executing on a client device, a user request for dietary assessment;
• sending the request to a server operating on a remotely located computing device that is communicating with the client device over a network, the client device and remotely located computing device including one or more processors;
• receiving, with the mobile application, in response to the request, a first plurality of image vignettes from the server, each image vignette:
• generated from a plurality of initial images associated with a multi-day dietary intake pattern and including a subset of elements depicted in the plurality of initial images, the elements depicting at least one or food or beverages, the subset containing fewer elements than depicted in the initial images,
• representing dietary characteristics of at least one of a different diet quality level or a different diet type associated with the multi-day dietary intake pattern, and
• displayed via the mobile application;
• receiving, via a graphical user interface provided by the mobile application, an initial user indication of one of the image vignettes in the first plurality of image vignettes as representative of the user's current diet;
• sending the initial user indication to the server and in response receiving via the mobile application one or more different image vignettes;
• displaying a subsequent display of image vignettes via the graphical user interface provided by the mobile application that includes the one or more different image vignettes;
• receiving, with the mobile application, a subsequent user indication of one of the image vignettes in the subsequent display of image vignettes as representative of the user's current diet;
• and
• receiving via the mobile application, from the server, a determination of a diet type and diet quality of the user's current diet, the determination based, at least in part, on the initial and subsequent indications.

A non-transitory medium holding executable instructions for image-based dietary assessment via a mobile application, the instructions when executed by one or more processors causing one or more computing devices to:

• receive, via a mobile application executing on a client device, a user request for dietary assessment;
• send the request to a server operating on a remotely located computing device that is communicating with the client device over a network, the client device and remotely located computing device including one or more processors;
• receive, with the mobile application, in response to the request, a first plurality of image vignettes from the server, each image vignette:
• generated from a plurality of initial images associated with a multi-day dietary intake pattern and including a subset of elements depicted in the plurality of initial images, the elements depicting at least one or food or beverages, the subset containing fewer elements than depicted in the initial images,
• representing dietary characteristics of at least one of a different diet quality level or a different diet type associated with the multi-day dietary intake pattern, and
• displayed via the mobile application;
• receive, via a graphical user interface provided by the mobile application, an initial user indication of one of the image vignettes in the first plurality of image vignettes as representative of the user's current diet;
• send the initial user indication to the server and in response receiving via the mobile application one or more different image vignettes;
• display a subsequent display of image vignettes via the graphical user interface provided by the mobile application that includes the one or more different image vignettes;
• receive, with the mobile application, a subsequent user indication of one of the image vignettes in the subsequent display of image vignettes as representative of the user's current diet;
• and
• receive via the mobile application, from the server, a determination of a diet type and diet quality of the user's current diet, the determination based, at least in part, on the initial and subsequent indications.
