Wearable Learning Support Device for Immediate Safety Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing learning support systems for children's traffic safety, such as WO 2019/240070, fail to provide immediate feedback on safety activities, leading to low effectiveness in habit formation as children often forget or neglect safety actions in designated areas.
Innovation Solution
A learning support device that includes a determining unit to assess safety activities in real-time and a notification unit to provide immediate feedback, such as praise or reminders, while the learner is in a designated area, using a combination of GPS, motion sensors, and a communication processor to ensure timely and relevant messaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If evaluation results are provided after children come home, then data processing time is reduced, but learning effectiveness deteriorates because children cannot associate feedback with the actual activity context
Solution Approach 1:
The notification unit is configured to provide determination results to the wearable electronic device before the child leaves the designated area, ensuring feedback is delivered while the activity context is still fresh in the child's mind. This preliminary action prevents the feedback delay problem by establishing a timing mechanism that delivers results immediately upon completion of the safety activity.
Solution Approach 2:
The system implements immediate feedback by notifying the child of their safety activity performance while still in the designated area through the wearable electronic device. This feedback loop allows children to directly associate the evaluation results with their actual behavior, thereby improving learning effectiveness and encouraging repeat safe behaviors.
2Reliability
If determination results are provided while the learner is in the designated area, then learning effectiveness is improved, but device complexity increases due to real-time monitoring requirements
Solution Approach 1:
The wearable electronic device performs multiple functions: it monitors safety activities, determines whether children are in designated areas, processes motion data, and provides notifications. By making the device multi-functional, the system avoids adding separate dedicated monitoring equipment, thereby managing complexity while achieving real-time feedback capabilities.
Solution Approach 2:
The wearable electronic device autonomously determines whether the child is in a designated area using its own sensors and processing capabilities, without requiring external monitoring infrastructure. The device self-manages the entire process from data collection to feedback delivery, reducing system complexity while maintaining real-time monitoring effectiveness.
3Productivity
If praise messages are provided frequently, then motivation is enhanced, but information overload occurs reducing message impact
Solution Approach 1:
The notification unit provides different types of messages (praise, correction, encouragement) based on the specific determination result and context. Rather than uniformly providing praise for all activities, the system tailors message content and frequency to the actual performance quality, ensuring that motivational messages are delivered selectively when they will have maximum impact.
Solution Approach 2:
The system provides praise and motivational messages selectively rather than continuously. By applying partial action (providing feedback only when appropriate based on determination results), the system avoids information overload while maintaining sufficient motivation. The feedback frequency is optimized to be neither too sparse nor excessively dense.

AI summary
A learning support device carried by a learner that learns an activity for ensuring safety includes a determining unit configured to determine whether the learner has done the activity in a designated area, and a notification unit configured to, after determination of the determining unit, immediately provide the learner with a determination result of the determining unit.
