The BI-Vital Toolbox offers a collection of tools for interacting & communicating with the related BI(lefeld)-Vital monitoring hardware, which is developed and used for research and teaching purposes in the AG Kognitronik & Sensorik at Bielefeld University. The user's vital data such as ECG, pulse, accelerations, orientation and environmental parameters can be transmitted from the BI-Vital to the smartphone via Bluetooth Low Energy (BLE). The data can then be displayed live in the app, saved or processed for further applications. The BI-Vital app is continuously supplemented with new features & tools and expands the functionalities of the BI-Vital hardware.
