Head-Mounted Display Pointer Speed Control for VR Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of head-mounted display apparatuses face inconvenience when trying to select menu items in virtual reality environments, as they need to incline their heads significantly, putting strain on their neck and head, and often require a separate input device that needs to be manually operated.
Innovation Solution
A head-mounted display apparatus that includes an image display unit, a head movement detection unit to track the user's head rotation, and a display controller that adjusts the pointer image's movement speed based on detected head rotation, allowing users to control the apparatus without holding an input device, minimizing inconvenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user inclines the head greatly to move the pointer in a large display region, then the pointer can be controlled without holding an input device, but the user's neck and head are burdened
Solution Approach 1:
The system dynamically adjusts the pointer movement speed based on the magnitude of head rotation detected by the detection unit. When the user rotates their head within a predetermined angle range, the pointer moves at a first speed; when the rotation exceeds this range, the pointer moves at a second speed that is faster than the first speed. This dynamic speed adjustment allows users to cover large display regions without excessive head inclination while maintaining hands-free operation capability
Solution Approach 2:
The control unit changes the parameter of pointer movement speed based on the detected head rotation amount. By establishing a correspondence between head rotation magnitude and pointer movement speed, the system enables efficient navigation across large display regions with minimal physical effort, resolving the contradiction between hands-free operation and neck strain
2Measurement precision
If a separate controller is used to control the head-mounted display apparatus, then precise control is achieved, but the user must manually operate the controller which reduces convenience
Solution Approach 1:
The system merges the input device functionality with the head-mounted display apparatus itself by using the detection unit (sensors) already integrated into the HMD to detect head movements. This eliminates the need for a separate external controller while maintaining precise control capability through accurate head movement detection and corresponding pointer control
Solution Approach 2:
The head-mounted display apparatus controls itself by using its own integrated detection unit to sense user head movements and automatically translate these movements into pointer movements on the display. The system serves itself by eliminating the need for external control devices, achieving both operational convenience and control precision

AI summary
A head-mounted display apparatus including an image display unit configured to display a display object image and a pointer image, a head movement detection unit configured to detect an amount of rotation angle of a head of a user, and a display controller configured to control a display mode of the pointer image, including a movement speed of the pointer image, within a display region of the image display unit. The display controller executes a first display control configured to change the movement speed of the pointer image in accordance with the detected amount of rotation angle so as to display the pointer image.
