Abstract:
In this paper, we present Back-to-Back, a novel real time hand gesture interface for 3D interaction based on double cameras. Back-to-Back dexterously makes use of the geometric complement of two back-to-back cameras. Held in hand, Back-to-Back could deduce hand’s 3D motion in real time. The basic idea is to extract good corner points from the image sequences captured by two cameras separately and track them while moving. By comparing the motions of two groups of points, the hand’s translation and rotation could be deduced accurately as well as other motion parameters. Back-to-Back is a prototype for gestural interaction on mobile devices equipped with two cameras. To further demonstrate its usability, we then analyze the requirements of 3D navigation task and design a strategy to navigate in 3D Space naturally by using Back-to-Back.
