Virtual Sensor Picture Update for Server-Based Cloud Gaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud gaming scenarios, applications running on servers lack physical sensors, preventing the terminal from updating the displayed picture based on user actions detected by sensors.
Innovation Solution
A virtual sensor is constructed in the server to mimic the structure and functionality of physical sensors on the terminal, allowing the server to receive sensor data, update multimedia pictures, and send updated data to the terminal for display, thereby simulating user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an application runs on a server without physical sensors, then the server can process and transmit multimedia pictures, but the server cannot detect user actions to update the pictures
Solution Approach 1:
The patent introduces a terminal device as an intermediary between the user and the server. The terminal's physical sensors detect user actions locally, then transmit this sensor data to the server. The server uses this transmitted sensor data to update multimedia pictures without needing physical sensors itself, thus resolving the contradiction between server-based execution and action detection capability
Solution Approach 2:
The patent creates a virtual copy of the sensor detection capability on the server side. Instead of requiring physical sensors on the server, the system transmits sensor data from the terminal to the server, allowing the server to process and respond to user actions as if it had direct sensor access, thereby enabling server-based applications to interact with user inputs
2Ease of operation
If the application runs on the terminal with physical sensors, then user actions can be detected and pictures updated, but the application cannot run on a server without installation
Solution Approach 1:
The patent divides the system into two functional segments: the terminal device handles sensor detection and data transmission, while the server handles application execution and multimedia processing. This segmentation allows the application to run on the server without installation while still maintaining sensor-based picture update capability through the terminal's sensor data transmission
Solution Approach 2:
The terminal device serves multiple functions: it acts as both the user interface for interaction and the sensor detection device. By transmitting sensor data to the server, the terminal enables the server-based application to access sensor information, thus providing both server-based execution capability and sensor-based update functionality through a unified system architecture

AI summary
This application relates to a picture update method and apparatus, a computer device, and a storage medium. The method includes: receiving sensor data sent by a terminal, the sensor data being collected by a physical sensor of the terminal; writing the sensor data into a virtual sensor, the virtual sensor corresponding to a structure of the physical sensor and is configured to support a sensor service associated with the physical sensor; reading the sensor data in the virtual sensor, updating a multimedia picture based on the sensor data, and generating corresponding updated multimedia data; and returning the updated multimedia data to the terminal, so that the terminal displays the corresponding updated multimedia picture based on the updated multimedia data.
