Study And Application Of Human Computer Interaction Technology For Personal Experience

Human-Computer Interaction(HCI)refers to the technology realizing information communicating between people and computers through input and output devices.Researches in the field of HCI never stopped since the electronic computer has been invented.HCI has changed from computer-centered to user-centered through years,which set the user's personal experience as one of new generation design goals.User's personal experience first design has become main direction of next HCI technology.In this paper,we concluded the basic principles of user's personal experience first HCI:user as the center,direct 3d interaction,meeting the user's aspiration during the interaction,and protecting user's patience.Facing with the user's experience,we bring forward a widely suited immersive 3d HCI paradigm,containing the camera scene(Camera),controlling roles(Controller),interactive object(Objects)and apply tools(Tools),which represent four basic elements to describe natural human-computer interaction process at 3d environment.The essay's works cover auto-stereoscopic display technology,gesture interaction technology and body interaction technology.For the auto-stereoscopic display part:Aiming at the problems of lenticular glass-free and auto-stereoscopic 3d display,such as difficult to evaluation,vertigo watching,an easy way to evaluate the stereo image's quality named fault-width measurement is designed.Using monocular camera to simulate human eye receiving 3d images,it calculate the ratio between most serious ghosting image width and the clearest dessert image width to show as the quality of auto-stereoscopic image.By measuring the imitation parameters of human eyes in this method,we calibrate the cameras layout and view order to improve the user experience in practical application system.For the gesture interaction part:We come up with a visual fusion data glove prototype system named Visual Glove.Which meets the needs of rotation calculation,bending detection,and 3d spatial location.A fast mapping method convert the curvature value to virtual hand joints position is realized by a hierarchical template matching method.Aiming at shortcomings of the realtime recognition and the accuracy of Hough-Circle-Detection algorithm,a feature-checking Hough algorithm is implemented to recognize the position of the luminous sphere on the glove.It combines the feature-checking method and the Hough recognition method to improve the recognition and location both efficiently and accurately.For the body interaction part:A method for body motion recognition based on posture sequence state chain is designed.By defining discrete postures and organizing them with certain time span,the identifying process is synchronized with action schedule.In the work of definition of posture only need to consider the main action node data characteristics,which has good flexibility and freedom,and help to enhance personal experience during action recognition process.As description of natural human-computer interaction and 3D display upon all these technologies,we build two user's experience first human-computer interaction and exhibition system,including glass free 3D interactive system,VR immersive virtual experiment system.The glass free 3D interactive system is constructed by auto-stereoscopic 3D design method and the posture sequence action recognition.The interactions and interests of the system are enhanced by the combination of stereo visual display and somatosensory interaction.The system shows great potential for business application.VR immersive virtual experiment system is constructed by Helmet-Mounted VR displays technology and gesture interaction technology.User's personal experiences have improved by the real and natural interaction in immersive environment.Through the actual realtime interactive system above,it can be proved that the human-computer interaction technology for personal experience has good application effects and social value.
