This paper tackles how to meet ever-changing user needs while lowering user cost in the development of ubicomp applications.Particularly, we have leveraged "distributed wisdom", which emphasizes the diversity of various participants and human groups (e.g., professional developers, novice programmers, and average users) in the lifecycle of ubicomp applications.The collaborative lifecycle-oriented learning (CoLL) approach is further presented to support the collaboration of different user groups of ubicomp apps.
