Abstract. In this paper, we conduct research on the developmental trend of modern wearable devices from perspective of the human-computer interaction. Wearable computers have to face the primary products market, the development momentum is very fierce, can be applied to various fields, has a great market potential, as therefore the research of the technology is also more and more. Wearable computer as representative one kind of emerging scientific and technological achievements, to instill the advanced concept of "people-oriented", although is only in the initial stage, convenient but it easy to carry, etc. has been the favor of people, visible in the future after it has potential of technological progress. Our research integrates the human-computer interaction to enhance the traditional wearable devices that will optimize the performance.

Abstract. In this paper, we combine the technique of ARM and ZigBee to design and implement the novel smart home system. Through analyzing the data transmission security enhancement model, we modify the traditional model with security concern. Each smart home system can be controlled by the server to facilitate access to residential property services, municipal services, such as weather forecast information. While using ZigBee as household interior various network can be easily will not have communication interface devices connected to the Internet gateway, does not need complex wiring or buy expensive appliances with communication interface. In the future research, we will numerically experiment our system and collect feedback for further optimization.
