Research On User Visual Imagery Based On Intelligent Virtual Camera

Virtual camera is set up as the camera in the virtual world, which is equivalentto the user’s digital eyes in the virtual world. The emergence of virtual camera forvisual technology brings new opportunities of constructing the "smart" eye.The intelligentize development of virtual camera is inevitable choice in thedevelopment of visual technology. From the camera, the video camera to the virtualcamera, visual technology will be intelligent vision technology system ofdigitalizing the visual imagery with simulating human visual perception of physicaland mental processes.Visual information model, which is to build the user’s visual information in thevirtual world, includes three aspects: the visual acuity, visual field, color vision.Individual differences in physiological characteristics, make the user’s visualinformation different on the same object, which is the main body factor of visualinformation model. Because of this, the virtual camera based on the user individualphysiological information to drive represent the user’s visual image, so as toconstruct the user’s visual image space, the virtual camera is the intelligent virtualhuman eyes.The way of visualize the visual imagery by intelligent virtual camera isaccording to the three stages of human visual image formation, including physicalawareness, mental processing and the spirit to recreation. Which shows the digitalimage space not only embodies the relevance with virtual space, but also thecreativity to the virtual space. In this kind of space form, the way of user’sperception will be rebuilt. Based on the test results of user experience, intelligentvirtual camera can meet the appeal of users’ body interaction and visualizing theuser’s visual, and bring the pleasure of emotional experience and interactionexperience for the user.To sum up, the development of the intelligent virtual camera, means that thevisual technology has entered a new stage to construct the human’s visualintelligence. Only with the intelligent module, which is based on the user’sphysiological and psychological information by virtual camera in watching, thetraditional visual technology system is likely to gradually build up a space withindividual life forms–the connection of imagery space and virtual space, realizethe consciousness of exchange activities between people and objects, also peopleand people, thereby subverting and reconstructing the way of human’s visualperception.
