Touchscreen Call History Delay to Prevent Accidental Redial
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face issues where users unintentionally initiate new calls due to the immediate display of the call history after terminating a call, leading to battery drain, network overload, environmental impact, and negative health effects from radiation exposure.
Innovation Solution
Implement a method in electronic devices with a touch-sensitive display that prevents new calls from being initiated within a determined time range after call termination, by either disabling selection in the area where the end call icon was displayed or requiring confirmation for new calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the call history is immediately displayed after call termination, then the user interface responds quickly, but the user may unintentionally initiate a new call due to insufficient time to stop finger motion
Solution Approach 1:
The system prepares the call history display in advance but delays its actual presentation until a predetermined time period after call termination has elapsed. This preliminary preparation allows the system to have the data ready while ensuring it only becomes visible when the user has sufficient time to complete their intended action, thus preventing accidental selections.
2Ease of operation
If the electronic device establishes unwanted telephone connections due to accidental user input, then the user interface is responsive, but battery resources are drained and network traffic increases
Solution Approach 1:
The system implements a predetermined time period delay before allowing new call initiation after call termination. During this period, the user interface remains unresponsive to new call requests, preventing accidental selections while still maintaining responsiveness for other essential operations. This selective delay reduces unnecessary battery consumption and network traffic caused by unwanted calls.
3Ease of operation
If the touch-sensitive display immediately responds to finger touches after call termination, then the user experience is responsive, but accidental call initiations occur due to incomplete finger motion stopping
Solution Approach 1:
The system implements a predetermined time period delay before the touch-sensitive display becomes responsive to new call initiation inputs after call termination. During this period, touches in the call history area are ignored or blocked, preventing accidental selections while the user completes their finger motion. After the delay expires, normal responsiveness is restored, maintaining good user experience for intentional actions.

AI summary
The invention relates to a method carried out by a computer (4) in an electronic device (1) with a touch-sensitive display (5), wherein the electronic device (1) is configured for providing a telephone connection to a second electronic device (2), the method comprising the steps: - provide a telephone connection to the second electronic device (2); - display an end call icon (18) on the touch-sensitive display (5) while providing the telephone connection to the second electronic device (2), wherein in case the telephone connection is terminated by the second electronic device (2): within a determined time range after termination of the telephone connection, a detection of the touch-sensitive display (5) being touched in a display area (19) in which the end call icon (18) was displayed during the telephone connection, does not initiate a new telephone call.
