VAEX-Bench Dataset Card

Dataset Description

VAEX-Bench is a controlled egocentric video benchmark for evaluating whether MLLMs can move from localized evidence readout to multi-scene spatiotemporal evidence integration. The benchmark includes paired extractive and abstractive reasoning tasks on the same scene and trajectory, enabling controlled diagnosis of failures in egocentric memory, spatial aggregation, and latent scene reconstruction.

Dataset Structure

VAEX-Bench consists of 10 controlled egocentric indoor scenarios. Each scenario contains one rendered walkthrough video and multiple QA pairs covering five task families: chronology, direction, distance, planning, and counting. Each family includes an extractive task and an abstractive counterpart.

Data Instances

Each instance in qa_pairs.csv represents a single QA pair associated with a specific video.

Data Fields

Below are the descriptions for each column in qa_pairs.csv:

video_id: Unique identifier of the video/scenario associated with the QA pair.
type: Reasoning regime of the QA pair, either extractive or abstractive.
question_type: Task category or task name, such as Appearance Order, Memory-Action, Relative Direction, Map Direction, Relative Distance, Map Scale, Route Plan, Simulation, Object Counting, or Global Counting.
question: Natural-language question given to the model.
ground_truth: Ground-truth answer used for evaluation.
answer: Model-generated answer for the given question.

Task Types

VAEX-Bench includes five paired task families:

Family	Extractive Task	Abstractive Task
Chronology	Appearance Order	Memory-Action
Direction	Relative Direction	Map Direction
Distance	Relative Distance	Map Scale
Planning	Route Plan	Simulation
Counting	Object Counting	Global Counting

Extractive tasks can be answered from localized, directly observable evidence. Abstractive tasks require integrating observations across multiple scenes, rooms, time points, or viewpoints.

Intended Use

VAEX-Bench is intended for evaluating multimodal large language models on egocentric spatiotemporal reasoning. It is designed for diagnostic research on localized evidence readout, multi-scene evidence integration, egocentric memory, spatial aggregation, and latent scene reconstruction.

Ethical Considerations

VAEX-Bench uses human-designed rendered indoor scenes rather than recordings of real people or private spaces. The released assets do not contain personal, sensitive, or scraped real-world data.
