useful?

I asked myself:

What does it mean for a product to be 'useful'?

A regular calendar is useful to much of the population, but what makes it truly useful is that it addresses the specific needs of the target audience. I began to analyze existing calendars that have specific purposes.


This is a truly amazing calendar that 'grows' as time goes by. the reason it is so fascinating is that the viewer can observe the progression of time and how the ink reveals the date and plant growing.




I'm not sure exactly how this calendar should be used, but using badges that can be worn as a reminder or that can be interacted with. i thought that maybe if my calendar consisted of badges, the mother-to-be could wear a badge stating her week of pregnancy.




This example shows a combination of time keeping and the functionality of a flower pot. I think it will be useful i try to incorporate the same idea into my own calendar. I just have to think of what pregnant women need.





This calendar encourages the viewer to interact with it. It is especially appealing to those who are addicted to popping bubble wrap! What actions do pregnant women like to take?
