Chris Baber is Reader in Interactive Systems Design, in the Department of Electronic, Electrical and Computer Engineering, at The University of Birmingham. He began his career researching speech technology (gaining a PhD in speech-based interaction in 1990 from Aston University). This work prompted an interest in providing speech input for mobile workers, and early attempts at fitting laptops to rucksacks inevitably lead to work on wearable computers. For the past six years, Dr. Baber has led a research team designing and developing a range of technologies that are worn by the person, either for data collection or communication. These technologies have been designed and trialled in a variety of domains, such as field archaeology, tourism, scene of crime investigation and distributed operations.
