In #AR, using real-time on-device 3D Gaussian splatting, we create the illusion that physical changes occur instantaneously, while a hidden robot fulfills the “reality promise” moments later, updating the physical world to match what users already perceive visually. 🤖

Even virtual agents’ actions can have physical effects, with motion paths that divert attention from the hidden robot. 🐝

Beyond materializing physical objects (seemingly out of thin air), users can manipulate out-of-reach objects via RealityGoGo — creating the illusion of telekinesis. 🪴

In collaboration with @sunniesuhyoung.bsky.social, Amna Liaqat, Rohan Jinturkar, Olga Russakovsky, and Ruth Fong.

Excited to share that Indu will be starting as a PhD student at UIUC this fall! 🎉

This is a qualitative study of how simple interactive mechanisms—filtering, overlaid annotations, and counterfactual image edits—might address existing challenges with static CV explanations, such as information overload, semantic-pixel gap, and limited opportunities for exploration.
A 3×4 grid showing bird images with visual explanations for Static, Filtering, Overlays, and Counterfactuals across three types: Heatmap, Concept, and Prototype. Heatmap row:
Color heatmaps over birds with labels “More Important” and “Less Important.” Filtering separates “Most Important Areas” and “Least Important Areas” with a “Show More” slider. Overlays add a tooltip: “The bird part that you are hovering near is: grey bill.” Counterfactuals include prediction text—“‘Heermann’s gull’”—and editable attributes like “Back Pattern” and “Bill Color.” Concept row:
Bar charts show the importance of features like “black bill” and “white tail.” Filtering splits “Positive” and “Negative Concepts” with sliders. Overlays label parts like “spotted belly” and “grey wing.” Counterfactuals show the prediction “pine grosbeak” with concept bars and edit options like “Tail Color.” Prototype row:
Birds are overlaid with patches showing similarity scores (e.g., “0.98 similar”). Filtering compares “Prototypes” and “Criticisms.” Overlays highlight areas with tooltips like “grey crown.” Counterfactuals include the label “Eastern towhee” and editable features like “Belly Color” and “Wing Color.”

Thanks for putting this together! I recently joined, and this is very helpful—would love to be added!
