2、fer various intelligent services by recognizing residents along with their life style and feelings. One of the key issues for realizing the smart home is how to detect the locations of residents. Currently, the research

3、effort is focused on two approaches: terminal-based and non-terminal-based methods. The terminal -based method employs a type of device that should be carried by the resident while the non-terminal-based method requires

4、no such device. This paper presents a novel non-terminal-based approach using an array of pyroelectric infrared sensors (PIR sensors) that can detect residents. The feasibility of the system is evaluated experimentally o

6、, comfortable, and safe residential environment [1], [2]. In general, the smart home aims to offer appropriate intelligent services to actively assist in the resident’s life such as housework, amusement, rest, and sleep.

7、 Hence, in order to enhance the resident’s convenience and safety, devices such as home appliances, multimedia appliances, and internet appliances should be connected via ahome network system, as shown in Fig. 1, and the

8、y should be controlled or monitored remotely using a television (TV) or personal digital assistant (PDA) [3], [4]. 3frequency identification (RFID) tag. Therefore, it is impossible to recognize the resident’s location if

9、 he or she is not carrying the device. In contrast, non-terminal methods such as Easy Living and Smart Floor can find the resident’s location without such devices. However, Easy Living can be regarded to invade the resid

10、ent’s privacy while the Smart Floor has difficulty with extendibility and maintenance.This paper presents a non-terminal based location-aware system that uses an array of pyroelectric infrared (PIR) sensors [15], [16]. T

11、he PIR sensors on the ceiling detect the presence of a resident and are laid out so that detection areas of adjacent sensors overlap. By combining the outputs of multiple PIR sensors, the system is able to locate a resid

12、ent with a reasonable degree of accuracy. This system has inherent advantage of non-terminal based methods whileavoiding privacy and extendibility, maintenance issues. In order to demonstrate its efficacy, an experimenta

13、l test bed has been constructed, and the proposed system has been evaluated experimentally under various experimental conditions. This paper is organized into four sections, including this introduction. Section II presen

14、ts the architecture of the PIR sensor-based indoor location-aware system (PILAS), and the location-recognition algorithm. Section III describes a resident-detection method using PIR sensors, and evaluates the performance

15、 of the system under various conditions using an experimental test bed. Finally, a summary and theconclusions are presented in Section IV.II. ARCHITECTURE OF THE PIR SENSOR-BASED INDOORLOCATION-AWARE SYSTEMA. Framework o

16、f the smart homeGiven the indoor environment of the smart home, an indoor location-aware system must satisfy the following requirements. First, the location-aware system should be implemented at arelatively low cost beca

17、use many sensors have to be installed in rooms of different sizes to detect the resident in the smart home. Second, sensor installation must be flexible because the shape of each room is different and there are obstacles

18、 such as home appliances and furniture, which prevent the normal operation of sensors. The third requirement is that the sensors for the location-aware system have to be robust to noise, and should not be affected by the

19、ir surroundings. This is because the smart home can make use of various wireless communication methods such as wireless LAN or radio-frequency (RF) systems, which produce electromagnetic noise, or there may be significan

20、t changes in light or temperature that can affect sensor performance. Finally, it is desirable that the system’s accuracy is adjustable according to room types.Among many systems that satisfy the requirement, the PIR sen
