The SOCIOTAL project aims to enable citizen-inclusive Internet of Things (IoT) by encouraging citizen participation and control over personal data. The project is developing key enablers like detecting face-to-face social interactions using Bluetooth and orientation sensors, and indoor localization using magnetic fields. An initial evaluation of the social interaction detection achieved 81.4% accuracy. The project is building an open platform and APIs to enable developers to access contextual information and detect social relationships between entities.
