6、 cell battery. We can put Beacon device at anywhere we want as long as there have networks. With iBeacon and smart phone APP, items will be smart to detect visitors around them in a certain area, and push item informa

17、 as well as WiFi. Smart items should be able to perceive visitors’ behaviors and make the right response. We proposed smart items design based on application of iBeacon. Smart items basically have three characterist

18、ics shown by Fig.3. Smart item is composed of iBeacon and APP in visitors’ smart device. It is able to perceive visitor’s existence, get visitors’ location as well as judging visitor’s preference by distance between

19、the item and the visitor, residence time a visitor stay around a certain item. Fig. 3. Illustration of smart item 1) Perceive existence of individuals around them Beacon sends BLE at intervals all the time, if anybod

20、y entered this region with smart devices, the APP installed in smart device beforehand will be triggered by detected BLE form Beacons. An iBeacon can be placed beside a culture artworks or an ancient historic spot,

21、visitors’ smart phone APP will detect the BLE, and push corresponding knowledge about this item to the smart phone. 2) Perceive individual’s location and provide navigation service An indoor navigation service is a

22、vailable based on three or more than three Estimate iBeacons. (Fig.4.) When a visitor enters a special region in the museum hall, the APP in smart device will detect the strength of BLE from different iBeacons, and c

23、alculate the distance between visitor and different iBeacons. We are able to get visitor’s position info inside the hall, and navigate visitors inside museum or an area. At the same time we can push relative knowledge

24、about the closest items at real time. Fig. 4. Location by 3 Estimate iBeacons 3) Detect individual’s preference If a visitor is interested in some item in the exhibition, they will be stay in front of the item for

25、a little longer time, or stay there for some while, and even trying to find more about it by approaching closer to it. The visitor might retrieve key words on line, share photos or relative links with friends on Socia

26、l Media. All these behaviors will take some time. Therefore, the APP will detect iBeacon signals and calculate visitor’s residence time. The distance between the visitor and the item is another measurement value of

27、 visitor’s preference. Usually, when someone visits a collection or local historic relics, he will read the brief introduction, and go around it to observe some details by closer to it. Let’s make a hypothesis, valu

28、e t means residence time in second, d means distance between item and visitor in centimeter, the judgment will be made according to the criteria below: We judge the preference or interests to a certain item by two co

29、nstraint conditions: Residence time is greater than or equals to 60 seconds, meanwhile, the distance is greater than 0, and less than or equals to 100 cm. If both of these two conditions are true, we think that the

30、visitor is interested in this item, and then, push him more information of the item, and Triggered AR APP in smart devices. And then, visitors are able to scan fiducial markers besides the item. The AR APP will tell m

31、ore about this item by interaction between 3D models and real world experiments. Else, we think the visitor has no interests to the item, and only push brief introduce via visitor’s application in smart devices on

32、site. With iBeacon and the criteria above, our item associated with iBeacon will have ability to detect the individual’s preference at real time, and then make corresponding responds. IV. LOCAL CULTURE PROTECTION SYST
