INTRODUCE EGOEVERYTHING

EgoEverything is a benchmark for long-context egocentric video understanding in AR environments. It leverages human attention signals abstracted from gaze data to generate natural multiple-choice questions, covering over 5,000 QA pairs across more than 100 hours of video.

Why EgoEverything

Existing long-context egocentric benchmarks often ask generic, template-like video questions and overlook how AR users naturally query what they attended to during interaction. EgoEverything fills this gap with gaze-grounded, human-reviewed MCQs that better reflect real AR memory and reasoning needs.

How EgoEverything is built

EgoEverything turns long first-person video and gaze into compact, reviewed MCQs through a gaze-oriented target sampling pipeline.

01

Long egocentric video + gaze

Start from long AR recordings with gaze traces aligned to what the wearer attended to.

02

Gaze-oriented target sampling

Sample meaningful targets around attention patterns instead of asking generic video questions.

03

Reviewed MCQ

Turn sampled targets into multiple-choice questions and keep the benchmark human reviewed.

04 / Examples

MCQs are grounded in target objects, visual evidence, and reviewed answer choices

EgoEverything examples show how a gaze-sampled target object becomes a natural multiple-choice question with supporting frames, colored evidence, and model-versus-ground-truth labels.

~60s clipTarget: striped blanketQ timestamp: 01:29

Was there a red and white chevron blanket on the sofa in the living room?

  • Yes, it was on the armrest of the sofa.
  • BNo, there was a plain red blanket on the sofa.
  • CNo, an orange and blue striped blanket was on the sofa.
  • DYes, but it was on the floor next to the sofa.
  • EYes, but it was folded neatly on the cushion of the sofa.

Why Item Presence: Asks whether a specific item appears in a specified place.

Current VLMs remain well below human performance

The homepage preview surfaces the headline gap: strong models improve over text-only baselines, but still struggle with long-horizon visual memory, small details, and attention-conditioned evidence.

05 / Analysis

Why current models struggle

EgoEverything exposes systematic limitations in current VLMs: longer recall intervals, targets farther from gaze, and smaller target objects.

01time

Longer recall interval

Performance drops as the answer depends on events farther back in the egocentric stream.

02gaze

Peripheral objects

Targets away from direct gaze are easier for humans to retain than for current VLM pipelines.

03scale

Smaller objects

Fine-grained, low-area visual evidence remains fragile even when the object is semantically simple.
