Gaze-Defined Virtual Space Regions for Lower-Burden Object Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cross-reality systems impose a heavy burden on users by requiring them to maintain the position and attitude of their hands to operate virtual objects, and only allow magnification of a single virtual object, obscuring other objects during operation.
Innovation Solution
An information processing apparatus that sets a first region in a virtual space based on a user's line-of-sight and limits the position within this region using attitude information to reduce user burden, allowing operation within an operable range defined by both line-of-sight and attitude.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user operates virtual objects by maintaining hand position and attitude, then the object operation precision is improved, but the user burden increases
Solution Approach 1:
The system automatically acquires attitude information from the hand controller and performs operations without requiring the user to consciously maintain specific hand positions. The operation execution unit automatically executes operations based on the acquired attitude information, making the system self-serve the user's intent without continuous manual adjustment.
Solution Approach 2:
The patent replaces the mechanical control system (where users physically maintain hand positions to control objects) with an automatic information processing system. The attitude information acquisition unit and operation execution unit substitute for manual mechanical adjustment, converting physical hand positioning into automatic digital operation execution.
2Ease of operation
If only the selected virtual object is magnified, then the operation ease on the selected object is improved, but the visibility of other virtual objects deteriorates
Solution Approach 1:
The patent resolves the contradiction by operating in the information dimension rather than the visual display dimension. Instead of changing the visual magnification of objects (spatial dimension), the system processes attitude information and operation commands in an abstract information space, allowing selective object manipulation without altering the overall visual field.

AI summary
Provided is an information processing apparatus that executes first setting processing for setting a first region within a virtual space based on a line-of-sight of a user viewing the virtual space, and second setting processing for setting a position within the virtual space based on an attitude of the user. In the second setting processing, after the first region is set in the first setting processing, a position to be set is limited within the first region.
