{"url":"/dataset/airletters","name":"AirLetters","full_name":null,"description_markdown":"This large collection of over 161,000 video-label pairs of video clips, shows humans drawing letters and digits in the air, and is used to evaluate a model’s ability to classify articulated motions correctly. Unlike existing video datasets, AirLetters’ accurate classification predictions rely on discerning motion patterns and integrating information presented by the video over time (i.e., over many frames of video). That study revealed that while trivial for humans, accurate representations of complex articulated motions remain an open problem for end-to-end learning for video understanding models.","description_withheld":null,"homepage":"https://www.qualcomm.com/developer/software/airletters-dataset","introduced_date":"2024-10-03","introduced_date_note":null,"introduced_by":{"paper":"/paper/airletters-an-open-video-dataset-of","title":"AirLetters: An Open Video Dataset of Characters Drawn in the Air","first_author":"Rishit Dagli","url":null},"license":{"name":"Data License Agreement – Research Use","url":"https://www.qualcomm.com/content/dam/qcomm-martech/dm-assets/documents/Dataset-Research-License_airletters.pdf"},"modalities":[{"name":"Videos","url":"/datasets/modality/videos"}],"tasks":[{"name":"Video Understanding","url":"/task/video-understanding","datasets_with_task":"/datasets/task/video-understanding"},{"name":"Video Classification","url":"/task/video-classification","datasets_with_task":"/datasets/task/video-classification"}],"languages":[],"variants":["AirLetters"],"data_loaders":[],"num_papers_in_archive":1,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
