Mobile Terminal User Presence Sensor Event Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals do not effectively notify users of missed calls or messages unless they periodically check the device's display, and users, especially those who are visually impaired, may remain unaware of missed calls even when the device is nearby.
Innovation Solution
A mobile terminal equipped with a user presence sensor, such as a three-axis acceleration sensor or temperature sensor, that detects the user's presence and triggers notifications, including sounds, vibrations, or LED indicators, when a predetermined event occurs, allowing the user to be informed of missed calls or messages only when they are present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mobile terminals periodically output sound or vibrate to notify users of missed calls or messages, then users may be notified of events, but users who are not in the vicinity of the mobile terminal or visually impaired will not be effectively notified
Solution Approach 1:
The patent introduces a proximity sensor as an intermediary device to detect whether the user is near the mobile terminal. This sensor acts as a mediator between the notification system and the user, enabling the system to intelligently determine notification timing and method based on detected proximity, thereby solving the problem of ineffective notification to absent or visually impaired users
Solution Approach 2:
The mobile terminal autonomously detects user proximity through the proximity sensor and automatically adjusts its notification behavior without requiring user intervention. The system self-determines whether to output notifications based on detected proximity levels, enabling visually impaired users and absent users to receive appropriate notifications without needing to manually check the display or interact with the device
2Loss of information
If conventional mobile terminals require users to periodically check the display to be aware of missed calls, then users can see notification information, but this creates inconvenience and users may miss important calls for long periods
Solution Approach 1:
The patent implements preliminary action by having the mobile terminal proactively notify users of missed events before users need to check the display. The system uses the proximity sensor to detect when users are near the device and automatically outputs notifications, eliminating the need for users to periodically check the display and ensuring timely awareness of missed calls and messages
3Reliability
If conventional mobile terminals output notifications continuously or periodically, then users may be informed of events, but this is not helpful when users are not in the vicinity of the mobile terminal and wastes energy
Solution Approach 1:
The patent applies dynamics by making the notification system adaptive and responsive to real-time conditions. The proximity sensor continuously monitors user proximity, and the notification system dynamically adjusts its behavior based on detected proximity levels. Notifications are output only when users are detected to be near the device, optimizing energy consumption while ensuring reliable notification delivery when needed
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
Ensures users are promptly notified of missed events without the need for constant display checking, enhancing awareness and usability for all users, including those with visual impairments, by providing targeted notifications based on their proximity to the device.
Implementation Method 1
The motion detector may be a three-axis acceleration sensor. The controller may generate the control signal when a detected motion variation value is equal to or greater than a predetermined reference value.
Implementation Method 2
The user presence sensor may include a temperature sensor that detects a body temperature of a user. The temperature sensor may be a contact type temperature sensor or a non contact-type temperature sensor.
Implementation Method 3
The output unit may switch on a light emitting diode (LED) contained in the mobile terminal, or cause the LED to blink to notify the user of the occurrence of the predetermined event.

AI summary
A mobile terminal having an event notification function which includes a user presence sensor that detects the presence of a user of the mobile terminal, a controller that detects the occurrence of an event, switches the user presence sensor on when it detects the occurrence of the event, and generates a control signal to notify a user of the occurrence of the event when the user presence sensor detects the presence of the user, and an output unit that receives the control signal and notifies the user of the occurrence of the event.
