Developed and integrated a dual touchpad finger touch detection feature for the SDL library, enhancing input support for Steam Deck devices. This work involved implementing new touch event pathways and extending touchpad state management in C, enabling reliable detection of finger touches on both left and right touchpads. Addressed a critical finger detection bug, resolving edge-case input gaps and improving gameplay responsiveness. The changes in libsdl-org/SDL focused on robust hardware interaction and real-time input handling, resulting in more consistent cross-device input reliability. Demonstrated a strong grasp of game development principles, input subsystem design, and performance-oriented programming for gaming hardware.
