They are found in electrical devices from coffee machines to aircrafts. The common denominator is that they are designed for the specific purpose of the application. Some of them are used in safety critical systems where it is crucial that they operate correct and as intended in order to avoid accidents that can harm humans or properties. Meanwhile, general purpose Commercial Off The Shelf (COTS) devices that can be found in the retail store, such as smartphones and tablets, has become a natural part of everyday life in the society. New applications are developed every day that improves everyday living, but numerous are also coupled to specific devices in order to control its functionality. Interaction between embedded systems and the flexible devices do however not come without issues. Security, safety and ethical aspects are some of the issues that should be considered. In this thesis, a case study was performed to investigate the feasibility of using mobile COTS products in interaction with safety critical systems with respect to functional safety.
