Geographic Reminder Display on Terminal Lock Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reminder systems on terminals only rely on time-based alerts, which can be ineffective as users may not be in the correct location when reminded, leading to missed notifications.
Innovation Solution
A method and device that display item content on a terminal's lock screen by acquiring the device's geographical position and checking if it is within a set display range or a larger reminding range, with reminders triggered through screen prompts, vibrations, or ring tones based on ambient light intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reminder is triggered only by time, then reminder system is simple, but reminder effectiveness deteriorates because user may not be at correct location
Solution Approach 1:
The patent combines time-based reminder triggering with location-based reminder triggering into a unified reminder system. The reminder is activated when either the scheduled time is reached OR the device enters the designated geographic range, merging two different triggering mechanisms to improve reliability without requiring completely separate systems
Solution Approach 2:
The patent introduces geographic range parameters (display range and reminding range) as intermediary elements that mediate between the user's physical location and the reminder triggering mechanism. These ranges act as intermediaries that translate spatial information into reminder activation conditions
2Measurement precision
If display range is set small, then notification precision is high, but reminder coverage deteriorates because user may be slightly away from location
Solution Approach 1:
The patent segments the geographic range into two distinct zones: the inner display range (for high-precision notifications when user is at exact location) and the outer reminding range (for broader coverage when user is nearby). This segmentation allows the system to provide different types of notifications based on the user's precise location within the segmented zones
Solution Approach 2:
The patent applies different notification qualities to different spatial zones: within the display range, the system provides visual notifications on the lock screen; within the reminding range but outside display range, it provides auditory or vibrational reminders. This local differentiation of notification quality matches the user's proximity to the target location
3Ease of operation
If lock screen displays item content, then user can see reminder without unlocking, but screen power consumption increases
Solution Approach 1:
The patent applies partial action by displaying only the necessary reminder information on the lock screen rather than fully activating the device. The screen displays item content in a power-efficient manner without requiring full system wake-up, providing just enough information for the user to recognize the reminder while minimizing energy consumption

AI summary
The present disclosure discloses a method and a device for displaying item content, which belongs to the field of computer technology. The method for displaying item content includes: when displaying a lock screen interface of a terminal, acquiring a current geographical position of the terminal (101); detecting whether the current geographical position is within a display range of a reminding item (102); and if the current geographical position is within the display range of the reminding item, displaying the item content of the reminding item on the lock screen interface (103). In the present disclosure, the problem of having a certain limitation due to performing the item reminding only according to the time in the related art is solved, and the effects of implementing effective reminding in the set display range and improving the reminding frequency are achieved.
