Purpose 
This study aims to explore advancements in medical education tools by focusing on Anki, a popular, open-source spaced repetition software (SRS). Anki's algorithm enhances long-term retention by progressively increasing review intervals as information is recalled correctly. We investigate the impact of a one-handed computer controller interface on Anki's usability and efficiency, comparing it to traditional keyboard setups. This research seeks to enhance learning tool accessibility and adaptability, potentially revolutionizing student engagement with educational materials. The anticipated outcome is to lay a groundwork for future advancements in medical education technology, emphasizing accessibility and effectiveness. 

Methods 
Subjects studied Anki cards using the two interfaces and were asked to provide feedback on each controller's accessibility, efficiency, and comparative usability. A questionnaire was administered to medical students who currently use Anki and have completed at least one session with a compact controller designed for one-handed operation. The survey was administered with a 5-point scale from strongly disagree to strongly agree. Using a two-tailed t-test, the results were analyzed to determine if there was a significant difference between the traditional keyboard and the one-handed computer controller interface.

Results 
Preliminary results (n=10) showed that the one-handed computer controller interface was more enjoyable (p <0.001), more likely to increase use (p=0.002), more portable (p<0.001), and more versatile across platforms (p=0.029). Students also reported being able to study in more places, feeling less distracted, and reviewing material more efficiently while using the one-handed controller. Ongoing data collection aims to expand these findings.

Conclusions
In summary, our study suggests the one-handed computer controller enhances Anki use in medical education. With positive feedback on enjoyment, portability, and efficiency, this innovative interface holds promise for reshaping learning tools, fostering adaptability, and improving accessibility in medical education.
