SAW-Bench: Learning Situated Awareness in the Real World

SAW-Bench (Situated Awareness in the Real World) is a benchmark for evaluating observer-centric situated awareness in multimodal foundation models — the ability to reason about space, motion, and possible actions relative to one's own egocentric viewpoint as it evolves over time.

Unlike prior benchmarks that emphasize environment-centric relations (how objects relate to each other in a scene), SAW-Bench probes whether a model can maintain a coherent observer-centric spatial state from egocentric video. It comprises 786 real-world videos captured with Ray-Ban Meta (Gen 2) smart glasses and 2,071 human-annotated question–answer pairs across six tasks. Even the best model trails humans by 37.66%.

Tasks

Task (`task`)	What it probes	# QA
`localization`	Where am I within the space (corner / side / center)?	200
`direction`	Where is a target relative to my current heading?	834
`shape`	What is the shape of the path I traveled?	546
`revplan`	How do I get back to where I started?	229
`memory`	What changed in the scene between two visits?	100
`affordance`	What action is feasible from my current pose?	162
Total		2,071

Fields

field	type	description
`task`	string	one of the six task names
`id`	int	id within the task
`question`	string	the multiple-choice question
`options`	list[str]	answer choices
`ground_truth`	string	the correct option text

Usage

Load the QA pairs:

from datasets import load_dataset

# one split per task
ds = load_dataset("ucsbai/SAW-Bench", split="direction")
print(ds[0])

# or all tasks combined
ds_all = load_dataset("ucsbai/SAW-Bench", "all", split="test")

Download the videos:

from huggingface_hub import snapshot_download

snapshot_download(
    repo_id="ucsbai/SAW-Bench",
    repo_type="dataset",
    allow_patterns=["videos_compressed/**"],
    local_dir="SAW-Bench",
)

Ethics, privacy & responsible use

SAW-Bench consists of real-world egocentric videos. Please read this statement before using the data.

Collection & consent. Videos were self-recorded by participants who consented to wearing the camera (Ray-Ban Meta Gen 2 smart glasses) in everyday indoor and outdoor environments. Incidental third parties (e.g., passers-by) and identifiable locations may appear in the background; no individuals were deliberately targeted, tracked, or directed.

Privacy minimization. Audio is removed from all clips. A face/identity-blurred variant of the videos was produced during the study. Even so, faces, license plates, or other identifying details may remain partially visible in some frames.

Permitted use. Non-commercial academic research only, under CC BY-NC 4.0.

Prohibited use. Do not attempt to identify, re-identify, locate, or contact any individual in the videos; do not use the data to train or evaluate face-recognition, biometric, surveillance, or person-tracking systems; do not use it commercially.

Removal requests. If you appear in a video, or are a rights holder, and want a clip removed, contact chuhan_li@ucsb.edu and we will promptly remove it.

By downloading the data you agree to these terms.
