Touch Terminal Wakeup via Vibration Signal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch terminals require a mechanical button for waking up the system, which is fragile and affects the appearance and service life of the device.
Innovation Solution
A method and system that scans the touch screen in a standby state for a vibration signal with predetermined characteristics during a touch action, allowing the touch terminal to wake up without a mechanical button, using a touch action detection module, a vibration signal detection module, and a wakeup module to determine and respond to specific touch actions like single-clicking or double-clicking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical button is used for wakeup, then the wakeup function is achieved, but the appearance is affected and service life is reduced due to fragility
Solution Approach 1:
The patent replaces the mechanical button system with a touch-based vibration detection system. The touch screen controller detects vibration signals generated by user touches, eliminating the need for mechanical buttons while maintaining the wakeup function. This substitution resolves the contradiction by removing the fragile mechanical component that limited service life and affected appearance.
2Use of energy by moving object
If the touch screen is closed to save power in standby state, then energy saving is achieved, but the wakeup response time increases
Solution Approach 1:
The patent implements periodic scanning of the touch screen during standby state at predetermined intervals. This allows the system to remain in low-power mode while periodically checking for wakeup touches. When a touch is detected, the system transitions to active state, achieving a balance between power saving and responsive wakeup timing.
3Measurement precision
If vibration signal detection is added to touch action detection, then wakeup accuracy is improved, but the detection complexity increases
Solution Approach 1:
The patent combines vibration signal detection with the existing touch action detection system. The touch screen controller simultaneously detects both touch actions and vibration signals, merging two detection functions into one integrated system. This approach improves wakeup detection accuracy by considering both touch presence and vibration characteristics without significantly increasing overall system complexity.

AI summary
The present invention relates to the technical field of touch. Provided are a wakeup method and system for a touch terminal and the touch terminal. The wakeup method for the touch terminal comprises the following steps: step A: scanning a touch screen in a standby state, when a touch action is detected to be present on the touch screen, further determining whether or not a vibration signal satisfying a preset characteristic condition and used for prompting wakeup of the touch terminal is detected at the same time; step B: if the vibration signal satisfying the preset characteristic condition and used for prompting the wakeup of the touch terminal is detected at the same time, then waking up the touch terminal. The present invention obviates the need for a mechanical button to be configured on the touch terminal to implement the wakeup of the touch terminal, thus not affecting the service life of the touch terminal and allowing the appearance of the touch terminal to be of increased appeal.
