Open source Web-based interaction with 3-dimensional building models via human interaction devices : a usability study

Abstract

The present contribution describes the concepts and implementation of a vendor and platform independent building monitoring framework. Building sensor data (e.g. electricity power consumption, air flow, temperature) is collected from various data sources and stored in a database. The data storage and user interface design concepts are introduced with focus on data preprocessing and web based distribution functionalities. A showcase implementation at the example of a building information terminal is utilized to conduct a usability study. The application implements support for various input methods. By using a personal computer, a touch screen and a gesture input device (control an application without direct physical contact), the study is conducted to specify which input device offers the best learning experience.
