Abstract
Recently, new interactive devices such as hap tic devices became available for game development. 6DOF hap tic devices give the user an opportunity "to feel" the simulated virtual environment in the way similar to the real world. Hap tic-based interaction can add a new dimension to "serious games" development. The user can "feel" objects surfaces and complex objects interaction forces in a 3D virtual environment. In this paper, we propose two hap tic-based serious games. In the first "T Puzzle" game, the user can "feel" the weight of objects, rotate and move the 3D puzzle pieces in the virtual world. This game can be used to improve the user's spatial abilities. In the second "Mol Docking" game, the player can feel interaction forces between molecular systems and learn the process of molecular docking in collaborative virtual environment.
