  Over the last half century, the main application of Brain Computer
Interfaces, BCIs has been controlling wheelchairs and neural prostheses or
generating text or commands for people with restricted mobility. There has been
very limited attention in the field to applications for computer aided design,
despite the potential of BCIs to provide a new form of environmental
interaction. In this paper we introduce the development and application of
Neuron, a novel BCI tool that enables designers with little experience in
neuroscience or computer programming to gain access to neurological data, along
with established metrics relevant to design, create BCI interaction prototypes,
both with digital onscreen objects and physical devices, and evaluate designs
based on neurological information and record measurements for further analysis.
After discussing the BCI tool development, the article presents its
capabilities through two case studies, along with a brief evaluation of the
tool performance and a discussion of implications, limitations, and future
improvement.
