3. OBJECTIVES NEWI North East Wales Institute of Higher Education
Develop a Home Automation Remote System
Use different inner and outer network technologies
Use devices that are easy to install
Use low-price materials and devices
Make it suitable for inexperienced users or even disabled people
Make it scalable for further add-ons
Manage multiple control points
Encourage standardization

WHY REMOTE CONTROL?
Enables control from almost anywhere (more comfortable)
Instant alerts greatly increase security
Backup emergency control
Optimal for people with reduced mobility
It can be combined with local control to give higher flexibility.
The network hierarchy has been rapidly moving lower in the chain towards smaller and more personal devices (Canosa, 2001)

10. INTERFACES & MIDDLEWARE
NEWI North East Wales Institute of Higher Education
INTERFACES & MIDDLEWARE
Middleware
Standard compatible
Link technologies (translation)
Robust
User interfaces (Local & Remote)
Must follow Heuristic Evaluation (Molich and Nielsen 1990)
High usability
Good visibility of system status
Match between system and real world
Error prevention (minimize error messages)
Aesthetic and minimalist
Help

12. Conclusion NEWI North East Wales Institute of Higher Education
The E-home is coming quickly
Standards are not completely established
Remote Control is necessary for certain purposes
Developing low-price systems will accelerate the process of turning our homes intelligent
The price of the “intelligence” in a house in comparison with its “body”, is insignificant
