MathDeck is a first-of-its-kind search interface designed to make it easier to edit, reuse, annotate, and share formulas. The system is based around a 'chip and card' metaphor inspired by board games.

CHI 2021 demo video; ECIR 2020 demo video - online system (Google Chrome strongly recommended)
AccessMath tracks whiteboard contents in lecture videos through time and generates keyframes. 'Ink' in keyframes can be used to jump to where that 'ink' is drawn in the video, or searched using image queries through the Tangent-V search engine. (NSF-funded project - Video Demo)
The first multi-modal equation editing prototype, with support for handwriting, typing, and image input for formulas, along with support for math + keyword search. (NSF-funded project; Video Demo)
A prototype that supports searching lecture videos for spoken keyterms (within-speaker), using a modified Dynamic Time Warping algorithm (NSF-funded project; Example Results).
Back in 2008, Kurt Kluever created the first video captcha, where users enter three words describing a video.

The dprl has participated in every CROHME competition since its inception in 2011, and co-organized the competition since 2013. CROHME has become a standard benchmark for handwritten formula recognition. The last CROHME was held in 2019, adding a typeset formula detection task.
ARQMath is a co-operative evaluation exercise aiming to advance math-aware search and the semantic analysis of mathematical notation and texts. ARQMath has two tasks, one for answer retrieval, and one for formula retrieval. The lab has been run for both CLEF 2020 and CLEF 2021 (lab web page).
