Vision-Based Mid-Air Unistroke Character Input: Precision, Recall, and Accuracy

This paper presents a novel vision-based mid-air unistroke character input method utilizing polar signatures. While the paper describes the method in detail, it lacks specific information on the achieved precision, recall, and accuracy of the system. To assess these metrics, further data and evaluation results are required. The provided information is insufficient to determine the performance of the proposed method in terms of precision, recall, and accuracy.
