The interaction between humans and machines is never as important as of today. Since the birth of the computer systems, the scientists have been devoting their lives looking for ways to communicate with the metal box. From the punched cards, command lines, graphical user interface, mouse and keyboard, and other interaction methods, we have now entered an extremely mobile and interactive era, signified by the emergence and prevalence of touch screens. As we break through the technological thresholds in speech interaction, somatosensory interaction, and even brain–computer interface, every field, including phones, cars, games and VR, is looking to create a more positive (or active) interaction between humans and machines, for the higher efficiency of the information exchange. In TechX HCI, we will bridge the theoretical basis in the interdisciplinary subjects with project implementation, introducing the students to the world of interface design, user experience design, creative computation and digital fabrication, as well as training their design thinking.
