Every lens leaves a blur signature—a hidden fingerprint in every photo. In our new #TPAMI paper, we show how to learn it fast (5 mins of capture!) with Lens Blur Fields ✨ With it, we can tell apart ‘identical’ phones by their optics, deblur images, and render realistic blurs.

Take hand-written notes in mixed reality! Our #CHI2025 paper "MaRginalia" explores how mixed reality can better support university students’ note-taking during in-person lectures. Students can stay engaged without needing to look down at their devices. #HCI #XR 🧵 (1/8)

Illustration of the use case scenario.]{Illustration of the use case scenario. The user wears a mixed reality head-mounted display holding a stylus over a tablet. In front of the user is a room with a big display of slides and a lecturer. The MR spatial panels are overlaid in the environment. To the left of the display is the Notes Panel, which has notes that mirror what is on the tablet. The display has the Slides Panel overlaid with a navigator of previous slides and some control buttons. To the speaker's right is the Transcripts Panel, which displays the lecture transcript.
