Problems solved by technology
[0021] The technical problem to be solved by the present invention is to propose a method for regulating the user's time perception and sense of presence in virtual reality, and to solve the problem that there is a mixture of independent variables in the study of regulating time perception in the prior art, and there is room for improvement in the selection of cognitive tasks. and the problem of not taking into account the sense of presence

Embodiment
[0058] In order to verify the impact of external timing factors and cognitive load on the user's time perception and sense of presence, in this embodiment, the visual timing factor is selected to be different degrees of light intensity (weak light, normal light, strong light), and the auditory timing factor is Clock ticks at different speeds (slow, normal, fast), the cognitive load task was a visual search task, the time distance estimates were collected by self-report, and the sense of presence was measured by a combination of subjective and objective measures.
[0059] In terms of subjects, a total of 46 subjects were recruited and divided into visual group and auditory group. Among them, 22 subjects participated in the verification of the visual group, 11 males and 11 females, aged between 18 and 27 years old, with an average age of 20.16 years old, 12 subjects had used HMD head-mounted display devices, and 21 One of the subjects was right-handed, the remaining one was left...

The invention relates to the field of user experience in virtual reality, which discloses a method for regulating user time perception and sense of presence in virtual reality, and solves the problems of independent variables and cognitive tasks in the research of regulating time perception in the prior art. The choice has room for improvement and doesn't take immersion into consideration. In the virtual reality experiment, the present invention divides the external timing factors into more detailed auditory timing factors and visual timing factors, and uses the control variable method to explore the single attribute of the timing factors involved; and improves the cognitive tasks used, And the sense of presence is included in the consideration of user experience; the relationship between external timing factors, cognitive load, time perception and sense of presence is sought by collecting experimental data for modeling analysis.
Description
technical field [0001] The invention relates to the field of user experience in virtual reality, in particular to a method for regulating user time perception and sense of presence in virtual reality. Background technique [0002] Since Ivan Sutherlan and his student Bob Sproull created the first virtual reality and augmented reality head-mounted display system: the Sword of Damocles in 1968, people have never stopped exploring virtual reality technology. In recent years, some consumer-grade head-mounted virtual reality devices such as HTC VIVE and Oculus Rift have begun to enter the homes of ordinary people, thanks to the development of computer graphics and related virtual reality technologies. On the one hand, it enables more people to experience the wonderful feeling of "immersiveness"; on the other hand, many problems that could not be solved due to the limitations of software and hardware conditions in the past have now returned to people's vision, and "is there a way ...
