AR Object Positioning for Field of View Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality (AR) systems, when the positional relationship between a user and a displayed object is inappropriate, it can lead to discomfort for the user due to partial or inadequate viewing of the object, causing an 'insufficient angle of view' issue, where only a part of the object is visible.
Innovation Solution
An information processing device and method that sets an initial display position for objects in a virtual three-dimensional space based on presentation position, size, and field of view information, positioning the object deeper in the depth direction than initially intended, ensuring it falls within the user's field of view, and optionally adjusting size and displaying animations to move the object into view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the object is displayed at the presentation position in the virtual three-dimensional space, then the object can be presented at the intended location, but only a part of the object is visible causing insufficient angle of view and user discomfort
Solution Approach 1:
The system performs preliminary positioning by setting an initial display position that is deeper in the depth direction than the final presentation position. This preliminary action ensures the object is initially visible in full within the field of view, preventing user discomfort before the object moves to its final position.
Solution Approach 2:
The system adjusts the object's position along the depth dimension (Z-axis) by setting it deeper than the presentation position. This dimensional adjustment ensures the object fits within the field of view while maintaining the intended presentation location, resolving the contradiction between positioning accuracy and viewing comfort.
2Area of moving object
If the object size is increased to improve visibility, then more of the object can be viewed, but the object may exceed the field of view area and cause display issues
Solution Approach 1:
The system changes the depth position parameter of the object rather than adjusting its size. By moving the object deeper in the depth direction, the system maintains the object's intended size while ensuring it fits within the field of view area, avoiding the need to compromise between visibility and field of view constraints.
3Illumination intensity
If the object is displayed closer to the user for better visibility, then the object appears larger, but only a part of the object can be viewed causing insufficient angle of view
Solution Approach 1:
Instead of moving the object closer to the user to improve visibility, the system inverts the approach by positioning the object deeper in the depth direction. This inverted positioning strategy ensures the entire object is visible within the field of view while maintaining appropriate display characteristics.

AI summary
There is provided an information processing device, an information processing method, and a program capable of appropriately displaying an object in a virtual space. Included is a setting unit that sets an initial position at which an object is initially displayed on a display unit on the basis of presentation position information regarding a presentation position to be presented in a virtual three-dimensional space of the object superimposed and displayed on a real world, size information regarding a size of the object, and field of view area information regarding a field of view area of the display unit that displays the object, in which the setting unit sets the initial position on a deeper side in a depth direction than a position represented by the presentation position information in a coordinate system based on the real world. The present technology can be applied to, for example, an information processing device that provides augmented reality (AR).
