The Learning Environment for Stars and Constellations in the Real World with Finger Pointing

We developed learning environment for stars and constellations with finger pointing under real night sky.This environment has some functions. First function is star name telling function. When a learner points a finger at a star with the sensor on his/her finger top, the system tells him/her name of the star and constellation with voice. Then, second function is star navigation function. If the learner know the name of a star, but he/she does not know where it is in the real sky, the system shows the path from current pointing position tithe target star. These two basic functions can be used by single learner, but also used collaborative learners. Third function is constellation tutoring function. The system asks questions about stars and constellations to learners. A learner answers the question by pointing at real star, and then the system corrects it. This function can be used for collaborative learners. Fourth function is collaborative focus point indication. Every learner uses each learning environment for his/her own, and every learning environment communicates each other. Every environment indicates the other learnerpsilas pointed star. Learners can know easily where the other learner points a finger at in the sky, and collaborate learning easily.
