The AugmenTable: Markerless hand manipulation of virtual objects in a tabletop augmented reality environment.

摘要

The AugmenTable is an augmented reality workstation intended for conceptual design and prototyping. It combines a thin form factor display, inexpensive web cameras, and a PC into a unique apparatus that has advantages similar to a head mounted display. The system operates on well-established computer vision algorithms to detect unmarked fingertips within an augmented reality scene. An application was developed to allow a user to manipulate virtual objects within the scene. This manipulation is possible through the use of three-dimensional widgets and controls that allow the user to control objects with natural fingertip motion. This thesis also documents similar previous work, the methods used to create the AugmenTable, and a number of avenues for advancing the system and the interactions it can offer users.
