Sense4HRI: A ROS 2 HRI Framework for Physiological Sensor Integration and Synchronized Logging
HCI Today summarized the key points
- •This article introduces the Sense4HRI framework, which integrates physiological signals into ROS 2–based human-robot interaction.
- •Because existing ROS 2 HRI systems lack support for standardizing and reusing physiological sensor data, it proposes an extension architecture to address this gap.
- •Sense4HRI separates sensor-specific packages and message formats, handling raw signals and interpretation results independently, and provides a topic structure suited to multi-user scenarios.
- •It also records both the device timestamp and ROS time to support synchronized logs, helping with combined analyses of multiple physiological sensors and other interaction data.
- •The prototype demonstrated potential by linking Polar PPG/ECG with ROS4HRI perception components, and future work still leaves multi-user handling and sensor extensibility as key challenges.

Why Read This from an HCI Perspective
This article is meaningful in that it treats physiological signals in HRI not as mere supplementary data, but as reusable infrastructure for estimating a user’s state. In particular, its modular design tailored to ROS 2 and ROS4HRI, synchronized logging, and time-series message standardization directly affect experimental reproducibility and the quality of multimodal analysis. It provides a practical reference point for both HCI/UX practitioners and researchers.
CIT's Commentary
From a CIT perspective, the key point of Sense4HRI is that it proposes an ‘interoperable interpretation structure’ rather than just ‘sensor connectivity.’ Physiological signals differ in format and time reference across devices, so in real research the bottleneck is often alignment and interpretation more than collection. This work separates raw signals from interpretation results and ties user ID, sensor ID, and time information into a consistent topic structure to reduce the operational burden of running HRI experiments. However, there is a risk that state estimation may ultimately remain limited to rule-based logic or simple classification; going forward, validation procedures that interpret emotional and cognitive states together with user context will become even more important. From the CIT standpoint, such infrastructure is noteworthy because it can serve as a foundation for personalized HRI and Human Digital Twins.
Questions to Consider While Reading
- Q.In a multi-user environment, what is the most realistic strategy for dynamically aligning physiological signals with person identification?
- Q.When estimating the offset between each device’s internal clock and ROS time, how should criteria for experimentally validating synchronization accuracy be designed?
- Q.When standardizing interpretation modules in physiological-signal-based state estimation, how should the balance between reusability and domain specificity be struck?
