Interactive virtual assembling in augmented reality

In this paper, a computer-aided methodology based on augmented reality to manipulate and interactively assemble virtual objects is presented. The developed system, based on both hardware and software implementation, allows the user to be immersed in an augmented scene (real world and virtual objects) by means of an head-mounted display and interact with the virtual components using a glove with sensors. The author presents the implementation of the system facing the problems concerning the interpretation of user’s intent to grasp and move the objects and the computer-aided assembly based on a novel approach concerning active features dynamic recognition. An example of implementation is herein reported and discussed.
