Human-Computer Interaction takes into account the development of human-computer interaction methods. It includes the development and preliminary investigation of a semiautonomous socially assistive robot and ergonomic design of human-CNC machine interface. This book also discusses about real-world applications of HCI techniques, non-intrusive physiological monitoring for affective sensing of computer users, modeling human-computer interaction in smart spaces: existing and emerging techniques, structured light illumination methods for continuous motion hand and face-computer interaction, a method for designing physical user interfaces for intelligent production environments and the role of head-up display in computer-assisted instruction.
