Multi-touch 3D navigation for a building energy management system

Abstract

This poster presents a multi-touch navigation interface for a building energy management system with a three-dimensional data model. It extends well established “rubber-band” 2D interaction gestures to work with a 3D world-in-hand paradigm with the help of a navigation widget to select the active manipulation axis. A nested, semi-transparent display of the data hierarchy requires careful selection of the manipulation pivot. A hit-testing scheme is introduced to select the most likely object within the hierarchy.
