HMD Object Position Control for Focus Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control technologies for head-mounted displays do not adequately ensure convenience for a wide range of users, as they often fail to maintain focus and immersion due to the user's field of view extending beyond the display screen, leading to reduced gaming experience.
Innovation Solution
A display control apparatus with a position control section that adjusts the position of objects in a virtual three-dimensional space based on the relative position between the user's input apparatus and the head-mounted display, using a light-emitting section and imaging apparatus to determine the object's position and attitude, and adjusts the display accordingly to enhance user interaction and immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the object position in virtual space is linearly changed based on input apparatus movement, then the user's field of view extends beyond the display screen, but the user cannot maintain focus and immersion
Solution Approach 1:
The patent applies dynamics by making the object position change non-linear when the input apparatus is close to the head-mounted display. Instead of a fixed linear relationship, the system dynamically adjusts the position mapping based on distance, preventing the object from moving too close to the viewpoint and thus maintaining focus and immersion while still allowing field of view extension.
2Ease of operation
If the object is displayed closer to the viewpoint when the input apparatus is close to the head-mounted display, then the user interaction is enhanced, but the user experiences focus issues
Solution Approach 1:
The patent applies preliminary anti-action by pre-defining a threshold distance between the input apparatus and the head-mounted display. When this threshold is exceeded, the system proactively changes the position mapping criterion to prevent the object from becoming too close to the viewpoint, thereby avoiding focus issues before they occur and maintaining reliable focus capability.
3Device complexity
If a fixed position mapping is used between input apparatus and virtual object, then the system is simple to implement, but it cannot ensure convenience for a wide range of users
Solution Approach 1:
The patent implements a dynamic position mapping system that selects different mapping criteria based on the distance between the input apparatus and the head-mounted display. This allows the system to adapt to different user scenarios and distances, significantly improving user convenience while maintaining reasonable implementation complexity through the use of distance-based conditional logic.

AI summary
A gaming apparatus includes a position control section and a display control section. The position control section controls a position of an object arranged in a virtual 3D space based on a relative position between an input apparatus used by a user wearing a head-mounted display and the head-mounted display. The display control section generates an image in the virtual 3D space including the object and displays the image on the head-mounted display. When a distance between the input apparatus and the head-mounted display is equal to a first distance or more, the position control section linearly changes the object position in response to a change in position of the input apparatus. When the distance between the input apparatus and the head-mounted display is less than the first distance, the position control section determines the object position in accordance with a criterion different from that used when the distance between the input apparatus and the head-mounted display is equal to the first distance or more.
