Head-Mounted Display Image Positioning via Object Marker Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display devices that overlay images on external scenes often hinder the user's visual field and lack the ability to easily adjust the position of the overlaid image to user intention.
Innovation Solution
A head-mounted display apparatus equipped with a display unit, an imaging unit, and a detector that captures images of objects, allowing the display controller to determine and adjust the position of the overlaid image based on detected features such as marker images, object colors, or frames, enabling the image to be displayed at a position and size conforming to the object's characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an image is displayed overlapped on outside scenery in a head-mounted display, then the user can access information while viewing the external scene, but the user's visual field is hindered and the image position cannot be easily adjusted to user intention
Solution Approach 1:
The system automatically detects objects in the external scene using an imaging unit and detector, then autonomously determines and displays the image at the appropriate position without requiring manual adjustment by the user. The display controller automatically matches the image position with the detected object position, allowing the system to serve itself in positioning rather than requiring user intervention.
Solution Approach 2:
The patent replaces manual mechanical adjustment mechanisms with an automated optical-detection system. Instead of requiring users to physically adjust or manually position images, the system uses an imaging unit to capture external scenes, a detector to identify objects, and a display controller to automatically calculate and set the image position based on detected object coordinates, substituting mechanical user adjustment with automated electronic positioning.
2Adaptability or versatility
If an image is displayed overlapped on outside scenery, then information can be superimposed on the visual field, but the image position is fixed and not easily changeable to match user intention
Solution Approach 1:
The imaging unit serves multiple functions: it captures the external scene for the user to view through the head-mounted display, simultaneously detects objects within that scene, and provides positional information for image overlay. This multi-functional approach allows the system to achieve position flexibility without adding separate dedicated components, as the same imaging unit performs viewing, detection, and positioning tasks.
Solution Approach 2:
The system automatically determines image position based on object detection results without requiring external input or complex control mechanisms. The display controller self-adjusts the image position by calculating coordinates based on detected object locations, enabling position flexibility through automated self-positioning rather than complex manual control systems.
3Ease of operation
If an image is displayed overlapped on outside scenery, then the user can see information in context, but the image position cannot be easily changed by the user
Solution Approach 1:
The system automatically positions images based on detected objects without requiring user control inputs. The display controller autonomously determines the optimal image position by processing detection data from the detector, eliminating the need for complex user control mechanisms while still achieving user-intended positioning through automated object-based placement.

Included are an image display unit to be worn on a user U's head and configured to display an image overlapped on outside scenery visually recognizable through the image, a camera, a detection controller configured to detect, under a condition that imaging data of the camera includes an image of a sheet, a marker as an identifiable feature of the sheet from the imaging data, and a display controller configured to determine, based on the marker detected by the detection controller, a position for the image to be displayed, and to display the image at the position being determined.
