Advances in technology enable users to increase their standards of living to make their life easier and comfortable. Smart spaces aim to enhance the intelligence level of the living environment and improve the quality of human life. Users are expecting spaces such as homes, buildings, campuses etc. to work for themselves. Cognitive Smart Spaces autonomously increase energy efficiency along with sensing, understanding and even predicting the needs of occupants. They are also capable of recognizing users and situations they are in and the spaces should react accordingly, e.g., by providing certain services or changes in the surrounding environment such as temperature, light illumination, HVAC systems etc. Therefore, cognitive smart space developments are gradually coming to different application domains, each with corresponding specific characteristics. The paper discusses different technologies and methodologies for development of systems for various cognitive smart spaces. This paper also presents case studies in the context of Cognitive Smart Spaces. Also, it gives a brief introduction about the various hardware and software components for the development of Cognitive Smart Spaces.
