Modern distributed embedded systems frequently involve wireless communication nodes where messages have to be delivered within given timing constraints. This goal can be achieved by adopting a suitable real-time communication protocol. In addition, connecting such systems with mobile devices is also desirable for performing configuration, monitoring, and maintenance activities. The Bluetooth low energy...
Low energy consumption is one of the primary issues that have to be addressed in body area networks to prevent frequent battery recharges in the nodes. Such networks are being increasingly used to acquire sensory data that need to be processed in real-time. The Bluetooth Low Energy (BLE) protocol is an attractive solution for implementing personal area networks with reduced energy consumption, also...
Tracking the position and the orientation of human limbs to reconstruct postures and actions is becoming a crucial need in several application domains, including medicine, rehabilitation, sport, and games. However, most available solutions are expensive, imprecise, or require an instrumentation of the environment. This paper presents a low-cost tracking system based on a set of wearable inertial measurement...
This work-in-progress paper presents an extension to the Arduino framework that introduces multitasking support. This allows to have more concurrent tasks instead of the single cyclic execution provided by the standard Arduino framework. The extension is implemented by integrating in a seamless way the ERIKA opensource Real-Time OS, maintaining the simplicity of the programming paradigm typical of...
