The Design Of Augmented Reality 3D Interactive Interface Based On HoloLens

The augmented reality interface,which provided by HoloLens expands the dimension of human-computer interaction interface,which enables users to interact with holographic images in the real environment through gestures or voice,thus bringing new experience to users.However,due to 3 dimension of the user interface and the change in the way of interaction,users cannot adapt to the augmented reality interface very well.In the process of using the HoloLens device,the error rate is relatively high,which affects the user experience.Therefore,this research is based on the the error phenomenon to finds out the interface design problems that lead to user error and come up with the design strategy to avoid the error.Firstly,we conduct the observation experiment of error behavior based on HoloLens and analyzed the user error.Three causes of user error behavior have been summarized,including interface layout problem,natural interactive feedback problem and interactive process design problem.Secondly,the research present design strategies,including design principles and design elements,which are proposed for these three problems.The design elements include six aspects: layout boundary constraint,information depth coding,spatial reference frame,interactive target size,cursor design,and rendering rate.Then the three-dimensional interactive interface of HoloLens is divided into two different types.The layout and design strategy of different types of interfaces are discussed respectively.At last,the design strategy was used to guide the practice.We select the live navigation as the task and complete the interaction design and visual design.Finally,the prototype development was completed based on Unity 3D.The practice shows that the proposed design strategy can be well applied to the case design.It can provide guidance for the design of augmented reality 3d interactive interface.
