Estimer is a kind of weather forecast for highly frequented office supplies. This fictive system predicts the availability of Printers, coffeemachines and other objects of daily use.


Within the workshop "Just real enough" at CIID in Copenhagen the concept "Estimer" was developed. The aim of this workshop was to generate and validate ideas with the use of prototypes.

"Estimer" assumes that human behavior can be tracked by sensors – the coffee machine could count how often and when it's used, for example. From this data a computer can calculate a forecast (»the coffee machine is always occupied from 8:00 till 9:30«) and is able to propose an alternative (»the coffee machine on the second floor is available«).

Right after the motto "Build. Test. Repeat." this idea was rejected, renewed and refined in the course with the help of countless prototypes.
