Could you build this?

No System-wide screen reprojection using OpenGL ES, sensor fusion, and Shizuku without root involves complex low-level Android display subsystem capture, surface warping, and real-time graphics pipeline injection.

What it would actually take: This architecture requires Android NDK (C++) with OpenGL ES/Vulkan rendering, capturing system display buffers via hidden framework APIs exposed through Shizuku (ADB privileged permissions), and binding real-time IMU sensor streams (gyroscope/accelerometer) to custom vertex shaders for perspective transformation. The primary hurdles are latency reduction, managing surface rendering without root permissions, and handling vendor-specific display pipelines (SurfaceFlinger hooks). Deep expertise in Android display architecture, graphics shaders, and IPC is required.
