Virtual Sensor Driver for Multi-OS Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with multiple operating systems (OSs) face compatibility issues with sensor devices due to varying hardware standards, leading to ineffective use of sensor data and increased power consumption.
Innovation Solution
A virtual sensor driver is configured to receive and transmit sensor data between different OS environments, allowing sensor devices to be shared across multiple OSs, with the driver activated only when an application using the sensor is executed, and the buffer size determined based on data reception interval and sensitivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sensor device is used in a guest OS environment without a virtual sensor driver, then the sensor device cannot be used due to hardware specification variations, but configuring a virtual sensor driver enables sensor data reception and transmission between different OSs
Solution Approach 1:
A virtual sensor driver is introduced as an intermediary layer between the physical sensor device and the guest OS. This virtual driver receives sensor data from the host OS and transmits it to the guest OS, enabling compatibility without requiring the guest OS to directly interface with the physical sensor hardware. The virtual driver abstracts the hardware-specific details, allowing the guest OS to access sensor data through a standardized interface.
2Productivity
If the virtual sensor driver is activated continuously to ensure sensor data availability, then sensor data can be transmitted efficiently, but power consumption increases
Solution Approach 1:
The virtual sensor driver is activated periodically or on-demand based on whether sensor data is actually needed by applications in the guest OS, rather than running continuously. The system monitors application requirements and activates the driver only when sensor data transmission is required, reducing unnecessary power consumption while maintaining productivity when needed.
3Reliability
If sensor data is transmitted between OSs continuously, then data availability is maintained, but processing speed decreases due to CPU power increase
Solution Approach 1:
The system extracts and transmits only the necessary sensor data that is actually required by applications in the guest OS, rather than continuously transmitting all sensor data. The virtual sensor driver filters and selectively transmits data based on application needs, maintaining data availability for required parameters while reducing CPU processing overhead and improving overall processing speed.

AI summary
Provided are an electronic device and a method for controlling same. In the method for controlling the electronic device, received is an input of a user command for executing a second OS during execution of a first OS. And a virtual sensor driver, for receiving sensor data from a sensor device, is provided when the second OS is executed. Sensor data is received from the sensor device by means of the provided virtual sensor driver. And the received sensor data is transmitted to an application of the second OS.
