The eggplant (left) is about to expire, therefore it is marked with a small white triangle. when clicked, it reveals more specific information and an option for generating recipes with this and other ingredients that are about to expire.
If a recipe includes ingredients which are currently not in the fridge, the user can add them to the integrated shopping list. While shopping, the user can remove the items from the list either by scanning products before he buys them, or delete them manually from the list. A price estimate is continuously generated and becomes more and more precise as more items are scanned.
Our choice of colors went through two phases: Originally we intended the colors to fit the natural colors of the product, until we realised that these colors do not offer the necessary contrast to a white font. Therefore, we pivoted to a more vibrant, but artificial color scheme, which still allows the user to recognise product categories.
Early on we intended to give the UI a playful and comic-like look. This is already visible in mid-fidelity wireframes (left).
Other functions include full control over temperature, cleaning cycles and history of purchased items. Making full use of all these features could cut both food waste and the use of electricity by a substantial margin.
