The major challenges for ubicomp systems are:
1. build a robust system
2. tell a compelling story
3. fulfill real needs
4. deploy in an authentic setting

In order to meet these challenges, Gregory and Beth suggest that a feasibility study is indispensable.
“Since it is already a difficult challenge to build robust ubicomp systems, you should not pay the price of building a sophisticated infrastructure only to find that if falls short of addressing the goals set forth in the compelling story. You must do some sort of feasibility study of cutting-edge applications before sinking substantial effort into engineering a robust system that can be scrutinized with deeper evaluation.” (p 538.)
