2.?Materials and MethodsIn this section, the developed measurement system, as well as the methodology followed for its field validation, will therefore be described.2.1. Measurement System Development2.1.1. General DescriptionA configurable m
The concept of ��intelligent environment�� arose in the late 90s to characterize a set of technological elements which were capable of communicating with the user and making decisions by means of an intelligent process. This interaction between user and device is carried out in a transparent manner, in the sense that the presence of these elements is sufficient to establish communication between them. In [1], the authors afford a solution to link contextual information with user interactions from daily activities, in an implicit and transparent way.
One of the best known examples concerning intelligent environments is radio frequency identification (RFID) technology. RFID systems are able to store and retrieve significant data from identified items by means of small tags in which this information can be easily read Inhibitors,Modulators,Libraries and written. These small tags can be attached Inhibitors,Modulators,Libraries to or incorporated into products, animals or people, and contain relevant information about the associated item, thus permitting their identification and the control of some of their features.The relative low cost of this technology, together with its rapid development and the tags’ adaptability for use on a great variety of surfaces have led to the constant expansion of RFID technology over the last few years. There are diverse fields of application of this technology.
In the fields of manufacturing and distribution, RFID systems have been used in Inhibitors,Modulators,Libraries the identification of packing and containers and for component tracking in factories [2,3]. Moreover, savings of time and paper are achieved in these cases because the inspection registers can be certified by writing on the tags which are attached to the elements [4]. Other authors [5] propose an application for a conference site through identification by RFID. In this work, people attending the conference wear RFID tags and the session room is equipped with antennas which detect the presence of the speakers in the room and facilitate the proceedings. This intelligent technology is also used in medical environments to locate the hospital equipment and improve its management, control Inhibitors,Modulators,Libraries patients’ activities in hospitals, or help people who need assistance [6].
RFID technology has also been applied in the field of robotics where it has been used as a complementary technology to laser Batimastat sensors for robot localization and for environmental Veliparib map construction, for example in [7]. The robotic platform described in [8] has been built to assist the visually impaired in supermarkets or airports. The intelligent system helps them to avoid collisions or to indicate how to follow itineraries.
