Dynamic Touch Button for Accidental Call Management Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accidental touches on touch screens of electronic devices can lead to unintentional answering or rejecting of incoming calls, causing inconvenience.
Innovation Solution
An incoming call answering and rejecting method on touch screens that utilizes dragging signals to differentiate between answering and rejecting actions, with visual cues and dynamic button movement to guide the user, thereby reducing accidental inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If answering button or rejecting button are displayed on touch screen for incoming call, then user can easily answer or reject call, but accidental touch may occur causing unintentional answering or rejecting
Solution Approach 1:
The button dynamically changes its position and size based on the user's touch interaction. When the user touches the screen, the button moves toward the touch location and enlarges, making the operation intuitive while requiring deliberate action. This dynamic behavior prevents accidental touches because the button only becomes actionable when intentionally interacted with, resolving the contradiction between ease of operation and reliability.
2Ease of operation
If touch screen is activated by touch, then intuitive operation is achieved, but accidental touch errors occur easily
Solution Approach 1:
The system applies preliminary anti-action by requiring the user to deliberately touch and drag the dynamic button to a specific location before the action is executed. This preliminary requirement prevents accidental triggers because the button must be intentionally manipulated through a multi-step process, countering the harmful effect of accidental touches while preserving intuitive operation.
Solution Approach 2:
The button's dynamic position and size changes in response to user interaction create an intuitive visual feedback mechanism. The button moves toward the user's touch and enlarges, making the system responsive and intuitive while requiring deliberate action to complete the gesture, thereby preventing accidental inputs.
3Device complexity
If static buttons are displayed for call management, then simple interface is maintained, but accidental touches cause unintentional actions
Solution Approach 1:
The button transitions from a static element to a dynamic one that responds to user touch by changing position and size. This dynamic behavior maintains interface simplicity (still a single button) while preventing accidental touches, as the button only becomes actionable when deliberately interacted with through the drag gesture.
Solution Approach 2:
The dynamic button acts as an intermediary between the user's touch input and the call management function. It mediates the interaction by requiring a deliberate drag gesture to a specific location, ensuring that only intentional actions trigger call management while maintaining a simple single-button interface.

AI summary
An incoming call answering and rejecting method, an electronic device, and a digital data storage media are provided. The method is applied to an electronic device having a touch screen and has the following steps. A request of an incoming call is received. A dragging signal is generated on the touch screen. When the dragging signal is an answering signal, the incoming call is answered. When the dragging signal is a rejecting signal, the incoming call is rejected.
