Gesture Trajectory of Vehicle Gesture Interaction Based on Semiotics

Gesture interaction as a non-contact natural interaction method will be widely used in vehicle interaction. The work aims to analyze the relationship between semiotics and gesture trajectory of vehicle gesture interaction by studying semiotics theory and perceptual research methods, thus forming a design flow for the study of vehicle gesture interaction from the perspective of gesture trajectory, so as to better assist the design of vehicle gestures. Based on semiotics theory and in combination with semantic differential, image scale method and analytic hierarchy process, etc., the extension and connotation meanings of semiotics were applied to collect and analyze the sample preferences of vehicle functional gesture trajectory, and excavate users'' deeper needs on gesture trajectory symbols. The analyzed and refined key gesture trajectory symbols were applied to gesture trajectory design, and to explore the relationship between semiotics and gesture trajectory of vehicle gesture interaction. The semiotics theory is used to study the gesture trajectory symbols. A method and flow that study the gesture trajectory based on semiotics theory are proposed, which proves that semiotics can be effectively applied to gesture trajectory design of vehicle gesture interaction.
