People that suffer from dementia or people with disease in the autism spectrum tend to elope from their caretaker’s attention, a fact that can lead to serious problems. Thus, a system that takes into consideration of the multiple requirements is of paramount importance. In this paper, a LoRa based SAR system is proposed in order to help in the localization of people with high risk of going missing. In contrast to most of the related systems, in this research article a different approach has been followed. Instead of focusing on the technology, in our approach a human-centered design has been used, leveraging the knowledge of Human-Computer Interaction (HCI) domain. Thus, the technologies used, are an outcome of the initial study. Finally, the system is evaluated using heuristic evaluation and questionnaires1 aBouras, Christos1 aGkamas, Apostolos1 aSalgado, Spyridon, Aniceto Ka  uhttp://telematics.upatras.gr/telematics/publications/long-range-based-iot-search-and-rescue-system-human-computer-interaction-preliminary-study-and
