Planet Editing Method Using Leap Motions

Universal courseware using motion recognition devices is very useful for students to learn universal science because it enables interactive learning. However, given that students change the radius of planets by the distance between their hands, it is nearly impossible to denote larger radii with their hands within fixed-hand recognition area of the motion recognition devices by a single expression. This chapter proposes a method that controls planets using motion recognition devices for courseware contents. The distance between hands is expressed by the sum of the difference of each position of the user’s hands. In the experiment, we validated the change of the radius of planets according to the difference of each recognized hand.
