Development principles of gesture interaction in smart space

Human-computer interaction in intelligent space is more complex and requires higher design principles. Gesture is an important interactive modal because of its natural and nonconflicting feature. The gesture interaction patterns of various devices fall into four types, i.e. barehanded/auxiliary touch/touchless mode. Gesture interaction meeting the demand of intelligent space should satisfy several development requirements, including multi-device collaboration, user-centered interaction and task-oriented design, each of which will be elaborated on.
