Mobile Terminal User Tracking Unit for Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face challenges in enhancing user convenience for content display, particularly in determining user presence and location to adjust screen settings and privacy protection, as users may have difficulty viewing content from a distance and risk of privacy invasion when others are nearby.
Innovation Solution
Incorporating a user tracking unit using cameras, microphones, and infrared sensors to recognize user presence and location, with a controller that adjusts display settings, such as size, alignment, and activation based on user proximity, and switches between video and voice call modes, and displays different content for privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display unit is always activated to ensure user can view content, then user convenience is improved, but energy consumption increases and privacy protection deteriorates when no user is present
Solution Approach 1:
The system performs preliminary detection of user presence before activating the display unit. The detection unit checks whether a user is present in advance, and only activates the display when user presence is confirmed, avoiding unnecessary energy consumption while ensuring user convenience when needed
Solution Approach 2:
The system continuously monitors user presence through the detection unit and provides feedback to the controller. Based on this real-time feedback, the controller dynamically adjusts display activation state, creating a closed-loop control system that optimizes energy consumption while maintaining user convenience
2Ease of operation
If the display unit is activated to show content, then user convenience is improved, but user privacy deteriorates when other users are nearby
Solution Approach 1:
The detection unit continuously monitors not only user presence but also identifies multiple users in the vicinity. This feedback information is transmitted to the controller, which then adjusts display activation accordingly - activating when a single user is present and deactivating or switching to private mode when multiple users are detected, thus protecting privacy while maintaining convenience
Solution Approach 2:
The display activation state is made dynamic rather than static. The system adapts its behavior based on real-time detection of user presence patterns, transitioning between active, inactive, and private modes to balance user convenience with privacy protection in different social contexts
3Adaptability or versatility
If user tracking using multiple sensors is implemented to protect privacy and enhance convenience, then user experience is improved, but device complexity increases
Solution Approach 1:
The detection unit is designed as a multi-functional module that performs multiple tasks using integrated sensors. The same sensor array detects both user presence and user identity, and can distinguish between single and multiple users. This universal detection unit reduces overall device complexity compared to having separate specialized components for each function
Solution Approach 2:
The patent combines multiple detection functions (presence detection, user identification, multiple user distinction) into a single integrated detection unit. By merging these functions and sharing sensor resources, the system achieves enhanced user experience through adaptive display control while minimizing the increase in device complexity
