Acceleration Sensor Vibration Control for Drowsy User Notification Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in completely awakening and accurately operating an information communication terminal to stop notification functions, especially when drowsy or with eyes closed, leading to potential errors such as unintended calls or messages to others.
Innovation Solution
Incorporating an acceleration sensor into the information communication terminal to detect user-induced vibrations, allowing the terminal to control notification operations based on detected vibrations, thereby simplifying the process of stopping notifications by requiring the user to shake the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user operates the operation unit to stop the notification operation, then the notification can be stopped, but the user may cause operation errors when drowsy or with eyes closed
Solution Approach 1:
The patent replaces the mechanical operation of pressing keys on the operation unit with a vibration detection mechanism. The acceleration sensor detects specific vibration patterns (such as shaking the device) to trigger notification stop, eliminating the need for precise manual key presses and reducing operation errors when drowsy
Solution Approach 2:
The vibration detection mechanism serves as an intermediary between the user and the notification system. Instead of directly interacting with the operation unit, the user interacts with the device through vibration, which is then interpreted by the control unit to stop notifications, providing a more reliable interface for drowsy users
2Reliability
If the key press time is longer than or equal to a predetermined time to stop the report, then the report stops, but if the key is not held down until the report is stopped, a re-report is made after a certain time
Solution Approach 1:
The patent changes the detection parameter from time-based (how long a key is held) to vibration-based (detecting specific shaking patterns). This allows the system to quickly identify the user's intent to stop notifications through a natural shaking motion, eliminating the need for prolonged key holding and avoiding unnecessary re-reports
3Ease of operation
If a simple operation is used to stop the notification, then ease of operation is improved, but the awakening effect is insufficient
Solution Approach 1:
The patent utilizes mechanical vibration as the operation input method. The user must shake the device with sufficient amplitude and frequency to generate detectable vibrations, which naturally promotes awakening while maintaining simplicity. The vibration requirement ensures the user is sufficiently aroused to control the device properly
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances user awakening and reduces operation errors by allowing vibration-based control of notifications, making it easier for users to interact with the terminal and preventing accidental notifications.
Implementation Method 1
acceleration detection means for detecting vibration occurring on the information communication terminal to generate vibration information

AI summary
An information communication terminal with a report function for use in the alarm includes the report function for awakening. However, since an operation required to stop the report function is performed in an operation unit, there is a risk that the user who is not in wakefulness makes an operation error. Using the information communication terminal including a sensor capable of detecting that the information communication terminal is shaken, a notification operation at a set time in the report function is controlled. Also, a control unit of the information communication terminal performs various kinds of control for the notification operation by partitioning vibration information detected by this sensor according to various patterns.
