Image Display Apparatus Proximity-Based Content Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems lack the ability to dynamically adjust the displayed content based on user proximity and gaze direction, leading to suboptimal user interaction and operability.
Innovation Solution
An image display apparatus equipped with a line-of-sight detection sensor and human detection sensor that determines when a user is within a specific distance and gaze direction, triggering a change process such as image enlargement or screen switching to enhance user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image display shows static content regardless of user position, then the device complexity is low, but the user operability and interaction quality deteriorate
Solution Approach 1:
The patent implements dynamic content adjustment on the image display based on real-time detection of user position and gaze direction. The display transitions from static to dynamic behavior by automatically changing displayed content when the user approaches within a predetermined distance and gazes at the display, resolving the contradiction between simplicity and user operability
Solution Approach 2:
The system uses detection sections to continuously monitor user position and gaze direction, then feeds this information back to the control section which adjusts the display content accordingly. This feedback loop enables the display to adapt to user needs without increasing apparent complexity for the end user
2Ease of operation
If the image display dynamically adjusts content based on user proximity and gaze, then the user operability improves, but the device complexity increases
Solution Approach 1:
The detection sections serve multiple functions: detecting user presence, determining user position, and detecting gaze direction. By making these detection components multi-functional, the patent reduces the need for separate specialized sensors, thereby limiting the increase in device complexity while maintaining improved user operability
3Adaptability or versatility
If the image display remains unchanged, then the device complexity is low, but the adaptability to different user situations deteriorates
Solution Approach 1:
The patent changes the display parameters (content, size, position) based on detected user position and gaze direction parameters. When the user approaches within a predetermined distance and gazes at the display, the system adjusts display parameters to enhance visibility and accessibility, achieving adaptability without requiring fundamentally different hardware configurations

AI summary
An image forming apparatus includes an image display that displays an image. In response to determining both that the image display is present in a detected user's gaze direction and that a distance between the user and the image display is shorter than a predetermined distance, the apparatus performs a change process on the image. After performing the change process, the apparatus determines whether or not the distance between the user and the image display is equal to or greater than the predetermined distance, and if so, returns the image back to a state prior to the change process.
