VR Character Teleport Placement to Prevent Motion Dizziness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users in virtual reality (VR) environments experience dizziness due to continuous movement of virtual characters, which is not well addressed by existing VR technologies.
Innovation Solution
A method and apparatus for controlling the placement of virtual characters in VR scenes by allowing users to select a designated movement from a first position, determining a second position, and teleporting the character directly to that position without appearing in between, using mechanisms like joystick or touchpad inputs and special effects to prevent dizziness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If continuous movement of virtual character is implemented, then movement freedom is improved, but user dizziness increases
Solution Approach 1:
The patent implements instantaneous teleportation of the virtual character from the first position to the second position without continuous movement. The character disappears from the first position and appears at the second position directly, skipping the entire movement process. This rushing through of the position change eliminates the harmful sensation of continuous movement that causes dizziness, while still achieving the goal of character relocation and maintaining movement freedom.
2Object-affected harmful factors
If teleportation is implemented, then user dizziness is reduced, but movement continuity is lost
Solution Approach 1:
The patent introduces a camera view transition as an intermediary element to mediate between the teleportation action and the user's perception. When the virtual character teleports, the camera view transitions to show the new position, creating a perceptual bridge that maintains continuity of experience. This intermediary camera transition helps preserve movement continuity in the user's perception while allowing the actual character movement to be instantaneous and non-dizzying.

AI summary
A method for controlling placement of a virtual character includes: displaying a virtual character at a first position in a virtual reality (VR) scene; receiving a first instruction in the VR scene, the first instruction indicating moving the virtual character from the first position by a designated movement; displaying, in response to receiving the first instruction, third indication information as a preview of the designated movement in the VR scene; determining, according to the first instruction, a second position by the designated movement from the first position in response to the first instruction; removing the virtual character from the first position; and placing the virtual character at the second position, the virtual character not appearing between the first position and the second position after being removed from the first position.
