The Human Cognitive Modeling Language (HCM-L) was developed for the Ambient Assisted Living (AAL) domain with the goal, to be easily understandable by future users: doctors, caregivers and even end-users themselves, i.e. anybody who needs help for successfully performing an activity. HCM-L is a lean modeling language with only a few concepts. The graphical notation was created considering principles for designing cognitively effective visual notations. This paper presents studies which tested the intuitive understandability of models that are formulated using this language.
