Human Experience in Regulated Offices Extended (HEROx) dataset

Synopsis:

Human Experience in Regulated Offices Extended (HEROx) is a synchronized multimodal dataset capturing human physiological, environmental, and perceptual responses during controlled indoor thermal exposure experiments. The dataset includes wearable peripheral physiology, EEG, questionnaire data, and environmental monitoring, all aligned to a standardized multi-phase protocol using an authoritative session timeline. It is released to support reproducible research in human–environment interaction, thermal comfort, and multimodal time-series analysis.

Experimental Conditions

• Colder environment exposure: Low Temperature (LT)
• Normal comfort environment exposure: High Temperature (HT)

Instrumentation

Each participant wore and was monitored by multiple sensors simultaneously:

1. Muse S Headband - EEG sensor worn on forehead (256 Hz sampling)
2. EmotiBit - Multi-sensor wearable on wrist (EDA/PPG/Motion: 15 Hz, Temp: 7.5 Hz)
3. Domx Sensor - Environmental sensor placed near participant (sampled every 10 seconds)
4. Ultrasound Sensor - Distance sensor near participant (~9.5 Hz sampling). Shared roof sensor during all sessions.
