Gyroscope Emulation in Guest OS via Host Driver Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual operating system (DUOS) computing devices, Android OS as a guest operating system cannot access hardware sensors, such as gyroscopes, when the Windows OS boots, as the access is outside its scope, leading to malfunctioning or undefined states.
Innovation Solution
A method is provided where a request for gyroscope data from a guest operating system is routed through a hardware abstraction layer to a second application in the user mode layer of the host operating system, which then sends the request to a driver in the kernel mode, allowing the guest OS to access and receive the gyroscope data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Windows OS boots and enumerates hardware, then the host operating system gains control of hardware sensors, but the guest operating system loses access to these sensors
Solution Approach 1:
The patent introduces a sensor emulator as an intermediary component that sits between the guest operating system and the actual hardware sensor. The emulator receives sensor data from the host OS and presents it to the guest OS as if it were directly accessing the hardware, thereby resolving the conflict between host OS control and guest OS access needs
2Adaptability or versatility
If the guest operating system runs as a virtual machine, then dual operating system functionality is achieved, but hardware sensor access becomes unavailable to the guest OS
Solution Approach 1:
The patent creates a virtual copy of the sensor within the guest operating system environment. Instead of providing direct hardware access, the sensor emulator generates synthetic sensor data that mimics real sensor behavior, allowing the guest OS to function with sensor capabilities while the host OS maintains actual hardware control
Data Source
AI summary
A guest operating system, launched by executing an application associated with a host operating system, is provided with access to a gyroscope associated with a computing device including a processor executing the host operating system. A first application associated with the guest operating system generates a request for gyroscope data. The request is received at a hardware abstraction layer associated with the guest operating system, and the request is sent from the hardware abstraction layer to a second application associated with the host operating system. The request is sent from the second application to a driver executing within a kernel of the host operating system. The driver retrieves the requested gyroscope data from the gyroscope. The retrieved gyroscope data is provided to the first application via the second application and the hardware abstraction layer.
