title	Visualizing Climate Data as a 3D Climate Torus
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 273-281

summary	In this research, a system is developed to visualize climate data as a 3D geometry, a climate torus. The system extracts time, dry bulb temperature, relative humidity, and wind speed information. Four points are created on a psychrometric chart using maximum temperature, minimum temperature, maximum humidity, and minimum humidity of a day. A closed curve passing these four points is drawn as a profile curve. 365 profile curves are generated for each day of the year. These curves are rotated along the vertical axis of the psychrometric chart, each at the incremental angle of 365/360, so that these curves rotate full 360 degrees to represent one year period. The system then generates a climate torus by lofting all the curves. Wind speed information is coded on the climate torus as holes. The diameter of the holes denotes wind speed. The climate torus is 3D printed after giving a minimum thickness to the surface. This process was assigned to sophomore architecture students. They showed great interest and gained better understanding of climate responsive design through the task. The climate torus has the future potential of coding more climate elements into it, e.g. solar radiation as colour, precipitation as texture, etc.

title	Facilitating fire and smoke simulation using Building Information Modeling
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 383.
summary	CFAST is a two-zone model which simulates fire growth and smoke transport. Manually modeling a building using CFAST user interface is a time consuming and error-prone process. In addition, the limitations in CFAST structure impede data transfer between CFAST and BIM (Building Information Modeling). In this research, we identified major limitations of CFAST, proposed solutions to the limitations, and developed a system for data interchange between BIM and CFAST. This greatly facilitated fire and smoke simulation. We further developed a visualization module to visualize the simulation results to overcome the problems when using SmokeView, an application developed by NIST (National Institute of Standards and Technology). A pilot test is conducted using this system. The simulation process was done in just a few minutes. This is expected to help architects to design buildings safer from building fires, and help students in learning building safety and fire related building codes.

title	A New Implementation of Head-Coupled Perspective for Virtual Architecture
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 251-260

summary	The process of projecting 3D scenes onto a two-dimensional (2D) surface results in the loss of depth cues, which are essential for immersive experience in the scenes. Various solutions are provided to address this problem, but there are still fundamental issues need to be addressed in the existing approaches for compensating the change in the 2D image due to the change in observer’s position. Existing studies use head-coupled perspective, stereoscopy, and motion parallax methods to achieve a realistic image representation but a true natural image could not be perceived because of the inaccuracy in the calculations. This paper describes in detail an implementation method of the technique to correctly project a 3D virtual environment model onto a 2D surface to yield a more natural interaction with the virtual world. The proposed method overcomes the inaccuracies in the existing head-coupled perspective viewing and can be used with common stereoscopic displays to naturally represent virtual architecture.

title	Fatal Fire Risk Checking for Residential Building Design
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 303-312

summary	Building fire puts great threat on people’s lives and causes huge numbers of fatalities each year. In 2007, total fire death in the United States alone was 3,430. The number of fatalities is distributed among residential 75.5%, non-residential 3.6%, vehicle 16.7%, outside 1.6%, and other 2.6%. Although much research has been done on building fire simulation to support designing safer buildings, all simulation systems currently available are focused on major factors in non-residential buildings such as bottlenecks, arching, pushing, etc. Residential building fires and non-residential fires are very different in many aspects. Therefore simulation systems focused on non-residential buildings have little effects on residential buildings. In this research, we analysed major factors causing deaths in residential building fires, and filtered out building design related factors. We then developed a system which shows the risk of fatal fire in residential building designs. This system is expected to help architects to easily detect potential risks of fatal fire and design safer residential buildings.

summary	Responsive environment uses human computer interface (HCI) to improve how human experience their surrounding. Many research aimed at different kind of interactive environment modules with new digital tectonics or computation components. However, those new environments are sometimes could be manipulated by components which are less use-friendly and complex than traditional counterparts. In this paper, we implemented a real responsive interface – the Spark wall system, which use 160 actuator modules as our responsive feedback interface and depth camera as sensing input. We built up multi-modal interface for different operating purposes allowing user control responsive environment with their human behavior. User could change their body posture to change the pattern of the wall and moreover define touch-input area on any surface. For the user’s perspective, a responsive environment should be simply and understandable control. A responsive artifact should also be able to dynamically correspond to different methods of operation according to the user's intentions.

title	HiGame: Improving Elderly Well-Being through Horticultural Interaction
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 95-104

summary	Family support is the key to the well-being problems of elderly. Unlike health problem, mental is often depended on the social network of elderly. How to enhance elderly well-being problems will become how to increase the interaction between elderly and their family. Horticultural interaction proves to be an effective but smooth impact on improving well-being problems of elderly. With a built-in ambient display and interaction game in mind, a Horticultural Interaction Game (HiGame) is developed, that has connection of both physical and virtual spaces. Elderly through physical watering, weeding, fertilizing to interaction with distant family. And distant family use virtual game of to support elderly.
