Graph: how to use the interface?

French version / version française English version The TUTTIFRUTTI website is a web-application fulfilling web-standards and requirements. It can be used on any device (computer, tablet, smartphone) through a web-browser (Mozilla, Chrome, Safari, ...). But you can also create your own App . In this latter case, you can use a barcode scanner to scan products, whereas in a web-browser you may have to type in the barcode manually instead. Note: the above link provides details for creating your App on smartphones running Android . This requires the addition of 2 extra Apps available on the Play Store. If you know similar Apps on the iTunes store, please fell free to contact the author of the blog who will update this news. Be advised: using the application on a device with a mouse (typically a computer) or without a mouse (typically a tablet or smartphone) implies a few differences in the available functionalities. So d

Create your Tuttifrutti OFF-Graph App

The tuttifrutti website is Web-browser oriented. No permissions are required. So you may use it very easily by opening the URL in a browser anywhere (PC, tablet, smartphone), entering into the barcode field the barcode of the product for which you are looking for similar products, and by pressing the GO button. However, entering the barcode manually is pretty tedious, and you may want to use external barcode-scanner App instead and also integrate the Tuttifrutti into an App-like icon on your smartphone. Here is how to proceed in order to: add an App-like icon of the site on your smartphone (Android) connect it to a barcode-scanner App for full integration Step 1: install and configure barcode scanner Installation From Google Play, search for the App Website shortcut and install it. Configuration and binding to tuttifrutti Start the App press the configuration "key" of your smartphone: a "settings" panel should appear; click on

Graph: spotting the products

Spotting (x, y) coordinates in the graph (x, y) axes of the graph range respectively from 0.5 to 1 (50%-100% similarity with product reference), and from 0 to 5 (worst to best nutrition score). x coordinate The computation of the x coordinate is complex and we just provide here a brief description of it by working with 2 examples: Let P be the product reference shown as an ellipse, and C its number of categories used for computing the similarities between products ( more details... ). Let C = 10, we divide the graph vertically into 10 stripes ( N ) of equal sizes; hence the right-most stripe ranges with x=]0.9; 1]. By the way, this is also the width of the ellipse showing our product reference. So in this stripe are shown all products with a similarity to the product reference of 100%. That being said, a product with a similarity of S=60% will be randomly located in the stripe ]N-1; N] where N = Math.Ceiling(S / (100 / C) = S*C/100 E.g. 1: Let C=10, S=60% => N=Math.Ce
