Fresh food tracker

How do you feel when you look in the refrigerator and notice food that has gone bad? I personally feel frustrated that I wasted the food.

Suppose that refrigerators had a touch-screen monitor that kept track of all the food in the fridge, and displayed a list of when each thing would go bad. Here's how it could work:

When you buy the food, you input the type of food and the approximate day that it will start to spoil. The touch-screen would be similar to what the store clerks use. First you choose from about 12 general categories of items. After you select one, then choose among several specific options within that category. After you've selected the specific item, input the date that the food will begin to spoil. Some products (like milk) have an expiration date stamped on them, while others do not. If it has the expiration date, you could select the option to view a calendar, then select the day. If it does not, then you select the option to view choices for number of days (up to 21 days). If you use the "number of days" option, then "1 day" represents tomorrow, "7 days" represents a week from now, etc.

To summarize, with 6 taps, you could input all the information:
1. Add new item
2. Choose general food category
3. Choose specific food type
4. Select expiration date
5. Select input method for expiration date (calendar or number of days)
6. Tap the day you expect the food to spoil.

When the touch-screen is not being used, it displays the list of food that is closest to spoiling. If any food has reached its expiration date, a red light flashes to let you know.

When you use up an item, just scroll down the list and select it, then push the "Delete" key.
