Dynamic Menu Positioning for Off-Center User Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in selecting menu items when their body position is not centered in the captured image, leading to awkward reaching motions due to fixed menu item displays.
Innovation Solution
A user interface system that captures images of the user, recognizes the position of a reference body part, determines the display position of selection elements based on this position, and adjusts their display to facilitate easier selection, using image capturing, recognition, and display adjustment technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If menu items are displayed in fixed positions on the display screen, then the display structure is simple and stable, but the user has to reach out their hand to select menu items when not centered in the image, reducing ease of operation
Solution Approach 1:
The patent applies dynamics by making the display positions of menu items dynamically adjustable based on the user's captured image position. Instead of fixed positions, the system calculates and updates display positions in real-time according to the user's location in the captured image, allowing menu items to adapt to the user's position and reducing the need for users to reach out their hands.
Solution Approach 2:
The system implements feedback by continuously capturing the user's image, determining their position in the captured image, and using this information to adjust the display positions of menu items. This closed-loop feedback mechanism ensures that the display positions are always optimized for the user's current position, improving ease of operation.
2Adaptability or versatility
If the camera is arranged at a freely-selected position around the display device, then the system is flexible and adaptable, but the user does not always appear at the center of the captured image, causing display position mismatch
Solution Approach 1:
The system performs preliminary action by calculating the user's position in the captured image before displaying menu items. It determines the appropriate display positions in advance based on the user's location, ensuring that menu items are positioned optimally for selection before the user interacts with them.
Solution Approach 2:
The patent applies parameter changes by adjusting the display positions of menu items based on the user's position parameters in the captured image. The system changes the positional parameters of menu items dynamically to match the user's location, maintaining ease of operation regardless of camera position flexibility.
3Adaptability or versatility
If the user appears off-center in the captured image, then the camera positioning is flexible, but the distance between the user's hand and menu items increases, requiring reaching motions
Solution Approach 1:
The system uses dynamics to adjust the display positions of menu items dynamically based on the user's position in the captured image. By making the display positions adaptive rather than fixed, the system minimizes the distance between the user's hand and menu items regardless of where the user appears in the captured image.

AI summary
To enable a user to easily select a selection element, a user interface device includes image capturing means for capturing an image of a user viewing a display screen, recognition means for recognizing the position of a reference part of the user's body appearing in the captured image, which differs from a selection position that is a position for the user to select a selection element displayed on the display screen, display position determination means for determining a display position of the selection element based on the position of the reference part appearing in the image, and display means for displaying the selection element in the determined display position.
