Worked on the ankidroid/Anki-Android repository to enhance input reliability and user experience by developing and integrating the AnkiShakeDetector feature. This component introduced a cooldown mechanism to debounce shake events, ensuring that rapid or repeated shakes would not trigger multiple unintended actions during flashcard review. The solution was implemented in Kotlin and involved updating both the AbstractFlashcardViewer and ReviewerFragment to utilize the new detector, effectively reducing accidental duplicate triggers. Focused on Android development and mobile user interaction, this work improved review throughput and consistency, addressing a key pain point in the app’s input handling without introducing new bugs.
