Touch Screen Remote Control Input Trigger Logic

Solution Overview

Problem

Conventional remote controls with touch screens face challenges in simultaneously realizing remote control functions and touch screen functions due to differences in operation triggers, leading to inability to perform continuous input, flicking, and dragging operations effectively.

Innovation Solution

An operation control method that determines whether a second manipulation occurs within a predetermined time after a first manipulation, allowing for appropriate operation control, including continuous, flicking, or dragging actions, by using a controller to differentiate between types of user inputs based on elapsed time and movement speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the remote control is designed to generate an IR signal when a button is pressed, then the remote control function is achieved, but the touch screen function requiring action on release cannot be realized

Engineering Contradiction:

Improveremote control functionVSAvoidtouch screen function

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the operation trigger adaptable based on the type of button. Pressable buttons generate IR signals on press, while touch screen areas generate signals on release. The controller dynamically determines the appropriate trigger event based on the input device type, allowing both remote control and touch screen functions to coexist without conflict

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent applies local quality by assigning different operational characteristics to different regions of the interface. Physical buttons are configured to trigger on press, while touch screen areas are configured to trigger on release. This localized differentiation allows each region to optimize its function while working together as a unified remote control system

Inventive Principle:

Principle #3Local quality

2Ease of operation

If the touch screen generates an IR signal when released, then the touch screen function is achieved, but the continuous input function requiring repeated signals cannot be realized

Engineering Contradiction:

Improvetouch screen functionVSAvoidcontinuous input function

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent applies continuity of useful action by implementing a long-press detection mechanism. When a button is held down beyond a threshold duration, the system generates repeated IR signals continuously until the button is released. This ensures that both touch screen tapping and continuous channel/volume adjustment functions work effectively

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent applies periodic action by generating IR signals at regular intervals during long-press operations. Instead of a single signal on release, the system emits periodic signals while the button remains pressed, enabling continuous function activation such as rapid channel changing or volume adjustment

Inventive Principle:

Principle #19Periodic action

3Ease of operation

If the remote control presses the button to generate a signal, then the remote control function is achieved, but the flicking and dragging functions of the touch screen cannot be realized

Engineering Contradiction:

Improveremote control functionVSAvoidflicking and dragging function

Core Design Contradiction:

AI summary

An electronic device having a touch screen and an operation control method thereof are provided. The electronic includes a touch screen which receives a plurality of manipulations; and a controller which determines whether a second manipulation is made on a screen displayed on the touch screen during a predetermined time period after a first manipulation is made on the screen, and controls to perform an operation corresponding to the second manipulation instead of an operation corresponding to the first manipulation to be performed, if the second manipulation is made during the predetermined time after the first manipulation is made.
