Solution Overview

Problem

The usability of always on display (AOD) functions in electronic devices is low due to their brief usage duration and limited appeal to users, who typically only view limited information and quickly exit the function.

Innovation Solution

The display method includes detecting changes in user states such as head angle, facial expressions, and line of sight to dynamically update the display manner of images, enhancing the appeal and playability of the AOD function by changing the appearance of virtual objects in response to these states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the AOD function displays limited information (time, notifications) in a static manner, then power consumption is reduced and device simplicity is maintained, but user appeal and usage duration are limited

Engineering Contradiction:
Improveuser appealVSAvoiddisplay complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic display content that changes based on user states. The display transitions from static information to dynamic content including virtual objects that respond to user actions, head movements, and facial expressions. This dynamic behavior increases user appeal while the system maintains power efficiency by only activating complex displays when users are present.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes display parameters based on detected user states. When users are detected through cameras or sensors, the system adjusts display brightness, content type, and animation intensity. This parameter adaptation allows the display to be simple and power-efficient most of the time, while becoming engaging and versatile when users interact with it.

Inventive Principle:
Principle #35Parameter changes

2Duration of action of moving object

If the AOD function uses simple static display, then ease of operation and low power consumption are achieved, but usage duration and user engagement are brief

Engineering Contradiction:
Improveusage durationVSAvoidpower consumption
Core Design Contradiction:
Duration of action of moving objectVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic updates of display content based on user presence detection. The system alternates between low-power static display mode and high-engagement dynamic display mode. Virtual objects are updated periodically when users are detected, creating an engaging experience that extends usage duration while maintaining overall power efficiency through rhythmic activation patterns.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses feedback from user detection systems (cameras, sensors) to control display activation. When users are detected, the display transitions to engaging dynamic content with virtual objects that respond to user actions. When users leave, the system returns to low-power mode. This feedback-driven approach extends usage duration by making the display responsive and engaging only when needed.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If virtual objects are added to enhance interactivity and user engagement, then user appeal and usage duration improve, but device complexity and processing requirements increase

Engineering Contradiction:
ImproveinteractivityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent uses virtual objects as simplified copies or representations of user actions and emotions. Instead of implementing complex real-time physics simulations or AI, the system uses pre-designed virtual objects that mimic user behavior through animation and state changes. These virtual copies provide intuitive interactivity while keeping the underlying system relatively simple and manageable.

Inventive Principle:
Principle #26Copying

AI summary

This application discloses a display method, an electronic device, and a computer storage medium. The method includes: displaying a first interface, where the first interface includes a first image in a first display manner; detecting that a state of a first user changes from a first state to a second state, where the state of the first user includes at least one of the following: an angle of a head of the user relative to the electronic device, a position of a face of the user relative to the electronic device, a gesture action, a facial expression, a position at which a line of sight is focused on a display, and an appearance feature; and updating a display manner of the first image to a second display manner, where the first display manner is related to the first state, and the second display manner is related to the second state. In this application, a display manner of an image changes with a user state. This can enhance the appeal of a display function to a user, and increase usage duration.
