Researchers have introduced S-EMBER, a new benchmark designed to evaluate AI's ability to retrieve information from continuous, egocentric video streams, mimicking the experience of wearable devices. The benchmark, comprising over 3,000 videos totaling 388 hours captured by Ray-Ban Meta smart glasses, includes nearly 10,000 question-answer pairs that require precise temporal localization within the video stream. Initial testing revealed a 'localization paradox,' where larger models, higher resolutions, and increased frame density did not improve temporal grounding accuracy, indicating a persistent architectural bottleneck for episodic memory in AI.
