Linked Display Screen Control During Power-Saving Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linked display systems using head-mounted displays (HMDs) and mobile terminals face usability issues due to power saving modes that turn off the mobile terminal display during inactivity, requiring user interaction to reactivate it, disrupting the viewing experience.
Innovation Solution
A linked display system that maintains the mobile terminal's screen display on during linked operations by disabling the power saving mode or using trigger-based screen activation, ensuring continuous viewing without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power saving mode is activated to reduce battery consumption, then energy efficiency is improved, but the display screen turns off requiring user interaction to reactivate, which deteriorates usability
Solution Approach 1:
The system automatically manages the power saving mode based on the operational state of linked devices. When a linked operation is detected, the mobile terminal automatically disables power saving mode to maintain display activation without requiring user intervention. This self-service mechanism resolves the contradiction by making the system adapt its power management behavior based on the operational context, thereby maintaining usability while preserving energy efficiency when appropriate.
2Ease of operation
If the display screen is kept constantly on during linked operations, then usability is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the power saving mode status based on the operational state of linked devices. The mobile terminal transitions between power saving mode and normal operation mode according to whether a linked operation is active, creating a dynamic power management strategy that balances usability and power consumption rather than maintaining a static state.
Solution Approach 2:
The system changes the operational parameter of the display (on/off state controlled by power saving mode) based on the detection of linked operations. When a linked operation is detected, the parameter changes from power saving mode (display off) to normal operation mode (display on), allowing the system to adapt its power consumption characteristics to the operational requirements.
3Loss of energy
If the mobile terminal requires user interaction to reactivate the screen from power saving mode, then battery consumption is reduced, but workflow efficiency deteriorates due to manual intervention
Solution Approach 1:
The system implements a feedback mechanism where the detection of linked operations triggers automatic adjustment of the power saving mode. The mobile terminal receives feedback about the operational state (linked operation detected) and automatically responds by disabling power saving mode, creating a closed-loop control system that eliminates the need for manual user intervention while maintaining energy efficiency when appropriate.
Data Source
AI summary
A linked display method to be executed by a first information device and a second information device which are connected so as to communicate with each other, the method comprising: starting a linked operation between the first information device and the second information device; disabling a power saving mode of the first information device to switch a screen display of a first display provided in the first information device to be constantly turned on; transmitting second divided data including a part of data for display being shown on the first display to the second information device; showing, on the first display, first divided data that remains after the second divided data is cut out from the data for display; by the second information device, receiving the second divided data; and by the second information device, showing the second divided data on a second display provided in the second information device.
