Ted Hall graduated with a Master's degree from the College of Architecture and Urban Planning at the University of Michigan in 1981 -- as a computer programmer instead of an architect. His career took a turn in 1980 when he accepted a summer job in the Architecture and Planning Research Laboratory (APRL) to help develop a software system for computer-aided design and building information modeling. Following graduation, he accepted a full-time position in the APRL. When the funding for that project ended in 1986, he entered the doctoral program, doing something completely different for his Arch.D. dissertation while continuing to work in the APRL as well. In 1994 he accepted a post-doctoral fellowship in the Department of Architecture at the Chinese University of Hong Kong. There he began to work with desktop stereographic visualization and 6-degree-of-freedom head and hand tracking for scientific visualization of building analyses -- especially computational fluid dynamics of urban air flow. After more than 13 years in Hong Kong, and a short stint at the New Jersey Institute of technology, he returned to the University of Michigan in 2009 -- now as an XR software developer in the Digital Media Commons, housed in the Duderstadt Center. He is one of the two developers of the software that runs the Michigan Immersive Digital Experience Nexus (MIDEN) -- an implementation of the "VR cave" concept. The software also supports Oculus and Meta headsets (from the Oculus Development Kit DK1 to the Meta Quest Pro) and the Microsoft HoloLens.
