Solution Overview

Problem

Computing device users often need to manually adjust display zoom levels, leading to inefficient processing cycles and inaccurate zooming due to the lack of consideration for individual user movements and preferences.

Innovation Solution

A system that adjusts display zoom based on user movements, generating a personalized zoom profile by observing and learning user behaviors, allowing automated and accurate resizing of content without manual input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual zoom adjustment is implemented, then user control over display zoom is improved, but processing efficiency deteriorates due to repeated manual adjustments

Engineering Contradiction:
Improveuser controlVSAvoidprocessing efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system automatically adjusts zoom levels by detecting user head position and movement without requiring manual input. The zoom controller monitors user behavior patterns and autonomously modifies display content scaling, allowing the system to serve itself rather than requiring continuous user intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements a feedback loop where the zoom controller continuously monitors user head position via sensors, analyzes zoom behavior patterns, and adjusts zoom levels in response to detected user movements. This closed-loop control eliminates the need for manual zoom adjustments while maintaining user intent.

Inventive Principle:
Principle #23Feedback

2Device complexity

If generic zoom settings are used, then device complexity is reduced, but user experience deteriorates due to lack of personalization

Engineering Contradiction:
Improvesystem simplicityVSAvoiduser personalization
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary analysis of user zoom behavior patterns during an initial calibration period, storing detected patterns in a profile. This advance preparation allows the system to subsequently apply personalized zoom adjustments automatically without requiring complex real-time decision-making infrastructure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The zoom profile is dynamically updated as the system continues to monitor and learn user behavior patterns over time. The system transitions from static generic settings to adaptive personalized settings by continuously refining zoom parameters based on observed user preferences and behaviors.

Inventive Principle:
Principle #15Dynamics

3Productivity

If automated zoom based on head position is implemented, then processing cycles are minimized, but measurement precision deteriorates due to difficulty in accurately detecting user intent

Engineering Contradiction:
Improveprocessing cyclesVSAvoiduser intent detection
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary monitoring and analysis of user head movements during a calibration phase to establish baseline behavior patterns. By pre-processing and storing these patterns in a zoom profile, the system reduces the computational burden during actual zoom operations while maintaining accurate user intent detection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback monitoring of user head position and zoom behavior correlations. By constantly analyzing the relationship between detected head movements and desired zoom adjustments, the system refines its measurement precision while maintaining efficient automated operation.

Inventive Principle:
Principle #23Feedback

AI summary

Display zoom setting adjustment systems are disclosed herein. In an example system, content is displayed on a display device according to a first zoom profile. The first zoom profile identifies different zoom values for different lean angles, where the lean angles are based on a position of a user of a computing device in a direction parallel to the display device. Zoom behaviors of the user are observed over a period of time, where the zoom behaviors are based on detecting a set of user movements. The first zoom profile is calibrated based on the observed zoom behaviors to generate a second profile. Using the second zoom profile, content is displayed on the display device and zoomed according to the parameters of the zoom profile. In this manner, zooming behaviors specific to a user based on their physical movements can be tailored, resulting in an improved user interface experience.
