Context-Aware Index Display for List Alignment

Solution Overview

Problem

Existing index display methods in electronic devices result in mismatched display of indices and lists, leading to obstructed user operations and inefficient power consumption.

Innovation Solution

The method involves displaying an index corresponding to a list only when the list is located in a preset display region of the interface, skipping index display when other elements are present, and adjusting index labels based on list information and display conditions to enhance matching and user convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the index is continuously displayed in the display interface, then the user can easily locate list items through the index, but the list may not be displayed while the index is displayed, resulting in a mismatch between the index and the list

Engineering Contradiction:

Improveease of locating list itemsVSAvoidmatching between index and list

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies dynamics by making the index display state changeable based on real-time detection of list display status. The system dynamically switches between displaying and hiding the index according to whether the list is currently visible, ensuring the index remains relevant and matched to the displayed content while maintaining ease of navigation when the list is visible.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by continuously monitoring the list display status and using this information to control index visibility. The system detects whether the list is displayed and feeds this information back to the display control logic, which then adjusts the index display state accordingly, creating a closed-loop system that ensures index-list matching.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If the index is displayed when the list is not visible, then the index provides navigation assistance, but it occupies display space and may obstruct other interface elements

Engineering Contradiction:

Improvenavigation assistanceVSAvoiddisplay space occupation

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The patent applies dynamics by making the index display state changeable based on real-time detection of list display status. The system dynamically switches between displaying and hiding the index according to whether the list is currently visible, ensuring the index remains relevant and matched to the displayed content while maintaining ease of navigation when the list is visible.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent extracts the index display function from continuous operation and activates it only when needed - specifically when the list is displayed. This selective extraction of the index display function eliminates unnecessary display space occupation while preserving navigation assistance functionality when the list is visible.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If the index is displayed for all lists, then comprehensive navigation is provided, but power consumption increases due to unnecessary index display

Engineering Contradiction:

Improvecomprehensive navigationVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the index display state changeable based on real-time detection of list display status. The system dynamically switches between displaying and hiding the index according to whether the list is currently visible, ensuring the index remains relevant and matched to the displayed content while maintaining ease of navigation when the list is visible.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent applies partial action by displaying the index only for lists that are currently visible and only when navigation assistance is actually needed. This selective partial display eliminates power consumption associated with displaying indices for invisible or unnecessary lists while maintaining comprehensive navigation capability when needed.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

This application belongs to the field of user interfaces, and provides an index display method, an electronic device, and a computer-readable storage medium. The index display method includes: displaying a first page in response to an operation of a user, where the first page includes a first list, and displaying an index corresponding to the first list when the first list is located in a preset display region of a display interface, so that both the first list and the corresponding index are displayed, thereby improving a degree of matching between an index displayed in the display interface and a list.
