Solution Overview

Problem

Existing computing devices require manual adjustments in system settings to scale display content, which can be inconvenient and disruptive to user workflow, especially when user-to-screen distance changes frequently.

Innovation Solution

Implementing a system that measures or estimates the user-to-screen distance using devices like eye trackers or cameras, allowing for automatic adjustment of display scaling settings in the operating system or applications to optimize content size based on the measured distance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of display scaling is implemented through system settings, then display content size can be controlled, but user convenience deteriorates due to frequent interruptions in workflow

Engineering Contradiction:

Improvedisplay scaling adjustment convenienceVSAvoidworkflow interruption time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically detects user-to-screen distance and adjusts display scaling without requiring user intervention. The computing device serves itself by monitoring distance metrics and autonomously modifying display parameters, eliminating the need for manual system setting adjustments and preventing workflow interruptions.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements a feedback loop where display scaling is continuously adjusted based on real-time detection of user-to-screen distance. The display scaling parameter responds dynamically to distance changes, creating a closed-loop control system that automatically adapts to user positioning without requiring manual input or causing workflow interruptions.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If automatic display scaling based on user distance is implemented, then user experience improves through seamless optimization, but device complexity increases due to additional sensing and control systems

Engineering Contradiction:

Improvedisplay scaling adaptabilityVSAvoiddistance measurement system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system leverages existing multi-functional components such as cameras or sensors that can serve both as user presence detectors and as distance measurement devices. By making these existing components perform the additional function of distance measurement, the system achieves automatic display scaling adaptability without significantly increasing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system introduces a software-based intermediary layer that processes distance data and controls display scaling, rather than requiring complex hardware modifications. This software mediator translates simple distance measurements into appropriate display parameter adjustments, achieving high adaptability while keeping the physical device complexity low.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A system is described for scaling display content on a computing device based on user-to-device distance. A measurement is taken of the distance between the user and the device and a scaling setting is determined using a predefined rule based on the measured distance. The scaling setting is applied to scale content on the display based on the user-to-device distance by changing settings in the operating system or changing scaling in an application. Embodiments include virtual desktop/application and localized implementations.
