In virtual reality,3D interaction design techniques are crucial to providing immersive experiences.The position and pose positioning of manual controller is always a big problem.Therefore,synchronous positioning and map construction techniques are used to improve its positioning performance,and a novel stationary strategy is introduced.The results showed that the camera control-ler built on synchronous positioning and mapping took an average of 9.40 seconds in 3D pointing tasks,slightly higher than HTC's 9.10 seconds and Oculus'9.25 seconds.In 3D placement and tracking tasks,camera controllers perform equally or slightly differ-ently than other controllers.It is worth noting that when the pose jump is not processed,the shift of 5cm is significantly perceived by the user compared to the perceptible threshold of 75％.However,the new strategy significantly reduces this abnormal perception and improves interaction fluency.It can be found that despite some challenges,the hand controller based on synchronous location and map construction performs well in most applications.This study provides a new way to improve the interactive experience of virtual reality.
