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) NEWI North East Wales Institute of Higher Education

PROPOSED HOME AUTOMATION SYSTEM Figure 2: Proposed Home Automation System NEWI North East Wales Institute of Higher Education

X-10 – Technique “Power Line Carrier” – Frame sent two times – Noise filter / Phase coupler – Up to 256 controlled devices Figure 3: X-10 frame NEWI North East Wales Institute of Higher Education

GSM Figure 4: GSM connection – AT / AT+ commands – Serial connection – SMS – MMS – Dials NEWI North East Wales Institute of Higher Education

INTERNET PROTOCOL Figure 5: Siemens UPnP – Control Points – IP devices IP cameras – Web browsers – XML – Siemens UPnP Stack Addressing Discovery (SSDP) Description (XML) – Control (SOAP) – Eventing (GENA) – Presentation (HTML,WML) 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 NEWI North East Wales Institute of Higher Education

Conclusion 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 NEWI North East Wales Institute of Higher Education
