Smart Watch Display Control via User Gaze Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart watches have limited operation time and power consumption issues due to their small size and wearable nature, leading to inconvenience and potential exposure of user privacy, while also risking unwanted payments through NFC communication.
Innovation Solution
A system and method for controlling a smart watch that uses sensors like speed change, tilt, and gyroscope sensors to manage display operations based on user movement and gaze direction, reducing power consumption and preventing unwanted payments by limiting payment functionality through an accessory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the portable terminal is brought close to the payment device for NFC payment, then payment convenience is improved, but the risk of unwanted payments increases
Solution Approach 1:
The smartwatch serves as an intermediary device between the user and the payment terminal. It detects the user's viewing state through sensors and determines whether to activate payment functionality, thereby mediating the interaction and preventing unwanted payments while maintaining convenience
2Ease of operation
If the smart watch displays content continuously, then user convenience is improved, but power consumption increases
Solution Approach 1:
Instead of continuous display operation, the system uses periodic detection of user viewing state through sensors. The display is activated only during periods when the user is actually viewing the smartwatch, creating a periodic on-demand operation pattern that reduces overall power consumption while maintaining convenience
3Reliability
If multiple sensors are installed and operated in the smart watch, then user privacy protection is improved, but power consumption increases
Solution Approach 1:
The sensor system operates autonomously to detect user viewing state and control payment functionality without continuous user intervention. The sensors self-manage the privacy protection function by automatically determining when the user is viewing the device, enabling reliable privacy protection while minimizing unnecessary power consumption

AI summary
Disclosed are an apparatus, a method, and a recording medium for controlling a portable communication terminal and a smart watch of the portable communication terminal, which control an operation of a display unit only when a user obtains information on a movement of the smart watch from a sensor installed in the smart watch and view the smart watch.
