The main aim of this project is to design for accessible interaction in home area networks. The project Assistive Housing was developed focusing on the elderly comfort, allowing home automation by using the television set and its regular remote control as an interface. The design strategy used to improve the legibility and accessibility of the home automation interface on the television screen was to use few and large graphical icons, with horizontal captions describing their function. The interaction is made through numbers as shortcuts avoiding navigation with keys. The idea of having a clean design, with few and large icons and the use of a consumer Electronics appliance that is already familiar to the user will be exploited in our work. In addition to the interface design, this work presents the solution to implement home automation and a sensor network to acquire context and to identify emergency situations. This project relies on power line communications. There are two other relevant projects to monitor elderly using sensor networks and integrating home automation, but they do not explore user interface design. In order to integrate this interface with a home automation system, a development board with an embedded microcontroller was used. The interconnection between the android and the automation system was made using a WIFI connection that is currently available in most android models. A commercial WIFI module was used connected to the development board in order to execute the experiment.
