Dynamic Scheduling for Wearable Display Power Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable display technologies for virtual, augmented, and mixed reality experiences have fixed duty cycles for communication, which do not adapt to varying data traffic and channel conditions, leading to inefficient power usage and potential disruptions in the user experience.
Innovation Solution
Implementing dynamic scheduling methods that adjust wake-up intervals and data transmission intervals based on the amount of data to be transferred and channel properties, allowing for flexible and efficient communication by dynamically determining the duration of downlink and uplink periods and adding or removing link pairs as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If fixed duty cycles are used for communication, then device complexity is reduced and ease of operation is improved, but power efficiency deteriorates and productivity decreases
Solution Approach 1:
The patent implements dynamic duty cycles that automatically adjust communication parameters based on real-time channel conditions and data traffic patterns. The system transitions from fixed to variable wake-up intervals, transmission power levels, and data rates, allowing the wearable device to optimize power consumption while maintaining reliable communication through continuous adaptation to changing environmental conditions.
Solution Approach 2:
The system dynamically modifies multiple communication parameters including duty cycle percentage, wake-up interval duration, transmission power, and data rate based on measured channel quality indicators. By changing these parameters in response to real-time conditions, the system achieves optimal power efficiency without requiring complex manual configuration or intervention.
2Productivity
If fixed duty cycles are used for communication, then device complexity is reduced, but productivity and data transfer efficiency deteriorate
Solution Approach 1:
The patent incorporates feedback mechanisms that continuously monitor channel conditions, data buffer status, and power consumption metrics. This feedback drives automatic adjustment of duty cycle parameters, enabling the system to maintain high data transfer efficiency by adapting to varying traffic demands and channel quality without requiring complex external scheduling infrastructure.
3Use of energy by moving object
If dynamic scheduling is implemented, then power efficiency and productivity are improved, but device complexity increases
Solution Approach 1:
The wearable device autonomously manages its own communication scheduling by internally processing channel quality measurements and automatically adjusting its duty cycle parameters. This self-service capability eliminates the need for complex external coordination or manual configuration, reducing the practical complexity burden despite the sophisticated adaptive behavior implemented.

AI summary
Disclosed herein a system, a method and a device for dynamic scheduling between a head wearable display and a console is provided. The head wearable display can initiate, at a first time instance, a first downlink transmission to the console. The head wearable display can dynamically indicate, to the console, an end of the first downlink transmission, at a second time instance when transfer of data of the first downlink transmission is complete. The head wearable display can dynamically cause, relative to the second time instance, the console to begin an uplink transmission. The head wearable display can receive an indication to dynamically start a second downlink transmission, at a third time instance when transfer of data of the uplink transmission is complete.
