Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion sensors are integrated into the wearable display to enable gesture control, then control precision is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent introduces radar sensors as intermediary devices positioned between the user and the cloud gaming system. These radar sensors capture motion data from the user's body movements and transmit them to the cloud gaming server, which then translates them into game inputs. This intermediary approach allows precise gesture control without requiring complex motion sensors to be integrated into the wearable display itself, thereby resolving the contradiction between control precision and device complexity.
2Adaptability or versatility
If motion sensors are integrated into the wearable display to enable gesture control, then control capability is improved, but power consumption increases
Solution Approach 1:
The radar sensors serve as external intermediary devices that handle the power-intensive motion detection function separately from the wearable display. The sensors capture motion data in the environment and transmit it to the cloud system, which processes the data and sends back simplified control commands to the wearable device. This distribution of computational workload significantly reduces the power consumption requirements of the wearable display while maintaining full gesture control capability.
Solution Approach 2:
The patent replaces the mechanical/electronic motion sensing system that would be integrated into the wearable display with an external radar-based detection system. The radar sensors use electromagnetic waves to detect body movements, and the cloud system translates these detections into game controls. This substitution eliminates the need for power-intensive onboard sensors and processing in the wearable device, thereby reducing power consumption while preserving control capability.
3Device complexity
If traditional controllers are used for cloud gaming, then device complexity is kept low, but control precision and user experience deteriorate
Solution Approach 1:
The patent replaces traditional mechanical game controllers with a radar-based motion detection system. The radar sensors capture detailed body movement data, and the cloud gaming server translates these movements into precise game inputs. This substitution eliminates the need for physical controllers while providing superior control precision through full-body gesture recognition, thereby improving measurement precision without significantly increasing overall system complexity.

AI summary
A wearable display of a client system is configured to receive and display a game stream representing a gaming application running on a cloud-based gaming server. To help control the gaming application, the client system includes or is otherwise connected to a smart ecosystem including one or more ecosystem devices each including radar circuitry. In response to the wearable display displaying the game stream, an ecosystem device is configured to transmit one or more radar signals towards the wearable display to generate radar data. Based on the radar data, the client system then determines motion data for the wearable display, user, or both and generates one or more game inputs for the gaming application based on the determined motion data.
