HCII also seeks to explicate the mechanisms of human perception, cognition, and action that are relevant to industrial, military, and consumer products. Projects in HCII involve the close collaboration of computer scientists, electrical engineers, neuroscientists, linguists and others in pursuit of knowledge relevant to the design of interfaces for human-computer systems.
A major research goal is the integration of engineering and computer science expertise. HCII faculty, graduate students, and postdoctoral students in these fields join together to design and construct hardware and software interfaces, as well as develop formal models of human perception, cognition, and action.
