People with limited mobility have considerable difficulties or even physical incapacities to perform daily tasks independently. The use of home automation is one way to overcome these motor disabilities. Many works have shown the dynamics of smart homes, home automation and assistance for dependents. However, very few of these accomplishments have focused on the design of intelligent systems which would allow non-experts to model and to adapt a home automation environment for people with reduced mobility. This design work is currently restricted to technicians, rather than occupational therapists or others who are able to best understand the needs of those with limited mobility. To take up these challenges, this paper proposes a design flow including a component approach for modeling system architecture and a range of services to meet the needs of both developers and users. Based on Model Driven Engineering, it automates the control code generation for home automation systems.
