This early-stage research article intends to explore the regulatory and liability requirements of a not yet fully developed subset of consumer Internet of Things (IoT) objects: the mixed-functions IoT devices. These objects could be wearables or not but could perform an e-health function, such as measuring your heartbeat, as well as consumer functions, such as displaying chat notifications. I argue that these mixed-functions devices will play an important role within smart homes as they will interact with new medical IoT devices to carry on rehabilitation and other medical functions at home. That is why it is important to start mapping down all the regulatory and liability requirements that might interest mixed-functions IoT device developers for them to understand which thread to follow in this regulatory and liability requirements maze.

The Autonomous Navigation System (ANS) constitutes a critical key enabling technology required for operating Maritime Autonomous Surface Ships (MASS). To assure the safety of MASS operations, the effective identification of potential objects and target ships interacting with the own MASS is quintessential. This study proposes a systematic method to identify the items interacting with the own MASS. This method is based on a similar approach previously employed for the encountering items’ identification in robotics, which is customised herein for the MASS needs. The developed method is applied to a short-sea shipping MASS. The environmental features, agents and objects related to her navigation are identified and ranked based on the frequency of encounter and the potential collision consequences. The results demonstrate the ability of the method to identify additional items in comparison to Automatic Identification System based data. The interactions with the small ships are considered as the most critical, due to their potential accidental consequences and their exhibited high frequency of encounter. This study results are employed to support the ANS design and testing of the investigated ship.
