The area of Human Computer Interaction, HCI, especially handles several usability aspects. This degree project emphasizes HCI in a context of, so called, Smart House. The report is divided into three main sections: theory, application, and measurement results. In the theory section we will present about the context of HCI and the content of HCI, such as HCI model and goals of HCI design. In the application section we discuss the use of mobile phones as a device to remotely control devices of smart houses, and present a system developed to support such services. In order to make the system more attractive, we decided to design it for two categories of operations, menu operation and direct-touch operation mode. Finally, we have used questionnaires for reasons of measuring user satisfaction. Through investigation and analysis of the result of this, we come to the conclusion that system usability is good.

Interaction, is an exciting and important area of computer science. It combines the physical, logical, conceptual, and language-based interactions between the human user and the computer for achieving some goals[14]. As other subjects, HCI is developed in order to meet the demand of human life. At the same time, the advance of computer technology is also promoting the development. In the 1980s, with the development of ergonomics, cognitive psychology, Artificial Intelligence and so on. Human Computer Interaction design and development has become one of the most popular topics in the computer world. In 1982 the ACM (Association for Computing Machinery) established SIGCHI (Special Interest Group on Human-Computer Interaction). The Association for Computing Machinery defines human-computer interaction as "a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them."[26] Since then the Human-computer interaction field has gone through nearly 30 years of development. Meanwhile, the new technology has been emerging continuously and the fields of HCI research have combined into a new subject: Interaction design. Human-computer interaction as an independent and important research area received the attention of the world computer industry. To a considerable extent, HCI now aggregates a collection of semi-distinct fields of research and practice in human-centered informatics[17]. It became another competitive field in 90 years in the computer industry. The improvements in computer technology that HCI technology also led the development of related software and hardware technology. It is a successful guarantee of new generation computer systems. 1.1.1 The History of Human Computer Interaction technology Human-Computer Interaction has gone through what many things do for adaptation
