Display Focus Switching Logic for Gamepad Text Input

Solution Overview

Problem

Users often inadvertently switch the focus from the game scene to the soft keyboard when using external devices like gamepads, leading to inefficiencies in text input during gameplay.

Innovation Solution

A display apparatus with a device interface that distinguishes between keys capable and incapable of switching focus, using a processor to manage focus switching based on specific click events from external devices, ensuring accurate text input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the external device allows free focus switching between game scene and soft keyboard, then the ease of operation is improved, but the reliability of text input is deteriorated due to unintended focus switches

Engineering Contradiction:

Improveease of operationVSAvoidreliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The external device keys are segmented into two functional categories: focus switching keys (first keys) and text input keys (second keys). This segmentation allows the system to distinguish between intentional focus switching operations and text input operations, preventing unintended focus switches during text input while maintaining operational ease.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different keys on the external device are assigned different functional qualities: some keys have focus switching function while others have only text input function. This local differentiation in key functionality enables reliable text input prevention while preserving overall ease of operation.

Inventive Principle:

Principle #3Local quality

2Productivity

If the focus switches to the game scene before text input is completed, then the productivity is improved by returning to gameplay, but the loss of information occurs as the text input is lost

Engineering Contradiction:

ImproveproductivityVSAvoidloss of information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system performs preliminary detection of focus switching key presses before executing the focus switch. When a first key is pressed during text input, the system detects this as an intentional focus switching command and processes it accordingly, preventing accidental focus switches that would cause text input loss while allowing intentional switches to resume gameplay.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the external device has no key pressing restriction, then the adaptability is improved by allowing all keys to function freely, but the ease of operation deteriorates due to accidental focus switching

Engineering Contradiction:

ImproveadaptabilityVSAvoidease of operation

Core Design Contradiction:

AI summary

The present disclosure provides a display apparatus and a control method. In the method, the focus interface is obtained in response to the text input command, and the first click event is listened if the focus interface is the application interface, where the first click event is used to switch the focus interface to the text input interface, and the first click time is generated by the focus switching key of the external device. Based on the first click event, the second click event generated by the non-focus switching key and sent from the external device is obtained, and the text data is generated and displayed based on the second click event.
