A Dataset on Human Reactions to Treadmill Perturbations Under Predictive Vibrotactile Feed

29 participants (16 male, 13 female) experienced unexpected treadmill perturbations in four directions under six experimental scenarios combining VR-induced cognitive load and predictive vibrotactile feedback. Synchronized multimodal measurements include instrumented treadmill data, VR headset IMU and task recordings, markerless motion capture, top-view videos, and questionnaire responses. Kamyar Rahmani published this 17.5 GB dataset on figshare in April 2026 under a CC-BY-4.0 license.

Use Cases

• Analyzing human balance recovery strategies based on synchronized motion capture and treadmill force plate data.
• Evaluating the effectiveness of predictive vibrotactile feedback timing on perturbation response based on the CLV1-CLV4 experimental scenarios.
• Studying the impact of divided attention on motor performance based on VR-induced cognitive load conditions.
• Developing models for human stability and fall risk assessment based on kinematic and kinetic data from controlled perturbations.

Strengths

• Includes data from 29 participants, providing a substantial sample for human subject research.
• Synchronized recordings from six distinct sensing modalities, enabling holistic analysis of balance reactions.
• Covers six controlled experimental scenarios, allowing for comparison of cognitive load and feedback timing effects.
• Dataset size is 17.5 GB, indicating a large volume of detailed sensor and video data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analytical methods.
• Data may reflect bias inherent to the controlled lab experiment and the specific participant cohort.
