Solution Overview
Problem
Conventional augmented reality (AR) technologies experience high power consumption due to continuous data transfer between AR devices and smartphones, leading to unnecessary resource usage.
Innovation Solution
An electronic device equipped with a communication module and processor that receives image information from an AR device, detects objects, acquires virtual information, and adjusts the transfer interval based on whether the object is within the AR device's viewing range, thereby optimizing data transfer and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous data transfer is implemented between smartphone and AR glasses, then screen sharing and AR content delivery are maintained, but power consumption increases and resources are wasted
Solution Approach 1:
The system transitions from continuous data transfer to periodic transfer based on object motion detection. When objects are detected to be moving within the viewing range, data transfer is activated; when objects are stationary or outside the viewing range, transfer is suspended. This periodic action maintains necessary screen sharing functionality while eliminating continuous power consumption during idle periods.
Solution Approach 2:
The data transfer mechanism is made dynamic by continuously monitoring object motion states and adjusting transfer intervals accordingly. The system adapts its behavior based on real-time conditions: high transfer frequency when objects are moving and within view, low or zero transfer when objects are stationary or outside view. This dynamic adjustment resolves the contradiction between maintaining reliability and reducing energy use.
2Loss of information
If continuous transmission of virtual information is performed, then AR content is always available, but unnecessary data transmission occurs when objects are out of view
Solution Approach 1:
The system implements feedback through continuous monitoring of object position and motion state. The processor detects whether objects are within the viewing range and whether they are moving, then adjusts data transmission accordingly. This feedback loop ensures AR content is transmitted only when necessary (when objects are in view and moving), preventing energy waste while maintaining content availability when needed.
Solution Approach 2:
The transmission parameters (data transfer interval, transmission frequency) are dynamically changed based on detected object conditions. When objects are out of view or stationary, transmission parameters are adjusted to reduce or stop data flow. When objects enter the viewing range and begin moving, parameters are adjusted to resume transmission. This parameter adaptation eliminates unnecessary energy consumption while preserving AR content availability.
3Measurement precision
If high frequency data transfer is maintained, then AR image quality is preserved, but power consumption and resource usage increase
Solution Approach 1:
The system applies partial action by transmitting data at high frequency only when necessary (when objects are moving within the viewing range). When objects are stationary or outside the view, transmission is reduced or stopped entirely. This partial application of high-frequency transfer maintains AR image quality during active periods while improving overall resource efficiency during idle periods, resolving the contradiction between quality and efficiency.
