NEWINorth East Wales Institute of Higher Education INTRODUCTION • Objectives • Home-Network • Why Remote Control? • Proposed Home Automation System • X-10 • GSM • Internet Protocol • Interfaces & Middleware • Conclusion
NEWINorth East Wales Institute of Higher Education OBJECTIVES • 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

NEWINorth East Wales Institute of Higher Education 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)

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

NEWINorth 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
