E-learning becomes a very important part in one?s learning progress especially in self-learning. In recent years, ubiquitous systems can even support the learning progress in real world, not only on PCs and mobile phones. Even mobile devices can be taken with a learner in everyday life, to provide more effective supports, the cooperation with ubiquitous devices such as sensors and embedded computers is necessary. With the improvement of ubiquitous technology, more and more services and supports can be provided to learners. However, learning systems have an important function: helping the learner improve his ability. In this paper, we present a method that can observe a learner?s behaviors by a ubiquitous environment and decide supports based on shaping principles. As a case study, we designed a ubiquitous gym for users who have some special purposes such as physical training or diet. The system can grasp a learner?s training actions and compare them with training requirements, and help the learner modify the behaviors and training plans based on shaping principle.
