Cognitive products use cognitive functions to work autonomously and reduce the amount of interaction necessary from the user. However, to date no method exists to support the integration of cognitive functions in common products. This paper presents a method that supports designers when exploring ideas for new cognitive products. The method is based on functions/actions that humans perform while using a product, as well as functions/actions performed by the product itself, all of which can be consistently modelled in an activity diagram. Initially, the system boundary of the product is drawn around the functions/actions performed by the product. Cognitive functions are then identified that are currently performed by the user, and can possibly be integrated into a new cognitive concept. The resulting concept is specified systematically by interpreting the system boundary of the product to include cognitive functions. This method has been verified via design projects performed by interdisciplinary student design teams, and an example of this work is presented.
