People with disabilities sometimes have considerable diffculties, or even physical incapacities, performing daily tasks independently. Many research works have introduced home automation as a useful way to overcome these activity limitations. However, very few of these accomplishments have focused on the design of intelligent systems which would allow nonexperts to model and to adapt a home automation environment for the disabled. 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 mobility or cognitive impairments. To take up these challenges, this paper proposes a design ow 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.
