Haptic interaction with a virtual 3D model: A multimodal interactive system for 3D solar system

Haptic interaction has become more and more important in interactive technology. In current human-computer interaction, haptic interaction has been considered as an important additional interactive method. The benefits of haptic interaction mainly include high efficiency, accuracy and naturalness. In this thesis, a multimodal interactive system was implemented based on a large volume 3D model of the solar system. This multimodal interactive system included two subsystems which separately used traditional computer interactive devices, a mouse and a keyboard, as well as a new haptic interaction device. These two interactive subsystems contained many relevant interactive functions for the user to interact with the model of the solar system and the models of celestial bodies inside it. In addition, the interactive methods for a large volume 3D model were studied in this research. Finally, a user study was employed to demonstrate the benefits of haptic interaction in a multimodal interactive system, and also the methods for improving current haptic technology had been discussed. To sum up, the work of the thesis includes a theoretical discussion, the implementation of a multimodal interactive system and a user study, which focuses on the research for haptic interaction in the field of human-computer interaction.
