We introduce MyEgo, the first egocentric VideoQA dataset designed to evaluate MLLMs' ability to understand, remember, and reason about the camera wearer.
Implicationpartial
Explicitly stated in the abstract as 'the first egocentric VideoQA dataset designed to evaluate MLLMs' ability to understand, remember, and reason about the camera wearer'
Verificationpartial
partial
Evidencepartial
Top closed- and open-source models (e.g., GPT-5 and Qwen3-VL) achieve only~46% and 36% accuracy, trailing human performance by near 40% and 50% respectively.
Implicationpartial
Direct numeric evidence provided in abstract with specific model names and performance metrics
Verificationpartial

Top closed- and open-source models (e.g., GPT-5 and Qwen3-VL) achieve only~46% and 36% accuracy, trailing human performance by near 40% and 50% respectively.
Implicationpartial
Direct numeric evidence provided in abstract with specific model names and performance metrics
Verificationpartial
partial
Evidencepartial
Surprisingly, neither explicit reasoning nor model scaling yield consistent improvements.
Implicationpartial
Directly stated in abstract as a finding from benchmarking, though specific evidence details would be in full paper
Verificationpartial
partial
Evidencepartial
Models improve when relevant evidence is explicitly provided, but gains drop over time, indicating limitations in tracking and remembering 'me' and 'my past'.
Implicationpartial
Directly stated in abstract as a key finding from the analysis
Verificationpartial
partial
Evidencepartial
Benchmarking reveals that competitive MLLMs across variants, including open-source vs. proprietary, thinking vs. non-thinking, small vs. large scales all struggle on MyEgo.
Implicationpartial
Strongly supported by benchmarking results showing low accuracy across model types, though specific comparison details would be in full paper
Verificationpartial
partial
Evidencepartial
These findings collectively highlight the crucial role of ego-grounding and long-range memory in enabling personalized QA in egocentric videos.
Implicationpartial
Directly stated as a conclusion from the findings, though supported by the evidence presented
Verificationpartial
partial
Evidencepartial
MyEgo comprises 541 long videos and 5K personalized questions asking about 'my things', 'my activities', and 'my past'.
Implicationpartial
Explicit numeric details provided about dataset composition and question types
