We explored the feasibility of using Bluetooth low energy (BLE) beacon sensors to determine when individuals with low vision (LV) use handheld magnifiers at home. Knowing the frequency and duration of magnifier use would be helpful to document increased magnifier use after successful rehabilitation training, or conversely, to know when someone has abandoned a magnifier and requires assistance. Estimote Sticker BLE beacon sensors were attached to the handles of optical handheld magnifiers and dispensed to eight LV subjects to use at home. Temperature and motion data from the BLE beacon sensors were collected every second by a custom mobile application on a nearby smartphone and transmitted to a secure database server. Subjects noted the date and start/end times of their magnifier use in a diary log. Each of the 99 diary-logged self-reports of magnifier use across subjects was associated with BLE beacon sensor recordings of motion (mean 407 instances; SD 365) and increased temperature (mean 0.20 °C per minute; SD 0.16 °C) (mean total magnitude 5.4 °C; SD 2.6 °C). Diary-logged duration of magnifier use (mean 42 min; SD 24) was significantly correlated with instances of motion (p < 0.001) and rate of temperature increase (p < 0.001) recorded by the BLE beacon sensors. The BLE beacon sensors reliably detected meaningfully increased temperature, coupled with numerous instances of motion, when magnifiers were used for typical reading tasks at home by people with LV.

Rapid advancements in mobile industry have emerged new technological ideas and applications for researchers by allowing smart devices over the last decade. In recent years, the need for Indoor Position Routing (IPR) and Location-Based Advertisements (LBA) systems are increasingly common, IPR and LBA systems have been becoming very popular. Nowadays, it has become possible to create software and hardware applications for IPR and LBA in indoor environments, thanks to developments of different technologies. The development of the system should be based on low-cost technology, it should be suitable for integration and indoors operation. New options and possibilities for indoor locations are presented by the iBeacon-Bluetooth Low Energy (BLE) radio protocol. iBeacon-BLE supports portable battery-powered system that can be smoothly distributed at low cost giving it distinct advantages over Wi-Fi. Therefore, in this study, a technological infrastructure is created to solve the navigation problem in closed locations using iBeacon-BLE technology, a data monitoring information system is proposed for smart devices of currently available technology for IPR, LBA with using iBeacon-BLE. The localization of the objects based on iBeacon-BLE and their combination are determined using the measured data with the developed application. To build an IPR system for indoor environments, the available hardware, software, and network technologies are presented. The concept of the indoor monitoring system and the technologies can be used to develop the IPR system are presented. This system is made up of iBeacon-BLE sensor nodes, a smart device and a mobile application that provides IPR and LBA services by measuring the distance between Transmitter (TX) and Receiver (RX). The proposed model uses the trilateration method, it allows the mobile application to determine the exact location of the object at the micro-level size. The proposed model uses sensory data to identify and trilateration the object’s position.

The IOT based live student tracking system is a mobile application ensuring the safety and security of the students. The main objective of the application is to build a smart watch for a school students.Now a days teachers and parents are worry about children because of the large amount students are bunking their classes.On certain cases,the teachers did not know about where the student is currently available and our proposed system gives a technical solution for the above problem.The system consists of school unit and bus unit which interact with the user.The school unit consists of a Bluetooth Low Energy device which is like a watch,that is used to send information once the student is out of Bluetooth range and also if the watch is removed by the student and the bus unit consists of mobile module where the app is placed.The parents acts like a end user,they can get a student exact location in their mobile phones.With this help of mobile application the parents and teachers can lively track the students location.

The RE.S.I.STO project targets visitors of Pisa medieval city, with the goal of providing high-quality digital contents accessible with smart devices. We describe the design, implementation and the test phases of the RE.S.I.STO application, whose goal is to automatically detect the proximity between visitors and artworks. Proximity is detected with a set of algorithms based on the analysis of Bluetooth Low Energy beacons. We detail our experimental campaigns which reproduce several museum layouts of increasing complexity at two pilot sites, and we compute the performance of the implemented algorithms to detect the nearby artworks. In particular, we test our solution in a wide open space located in our research institute and by performing a real deployment at the Camposanto Monumentale located in Pisa (Italy). The obtained performance varies in the range of 40% to perfect accuracy, according to the complexity of the considered museum layouts. We also describe a set of stress and stability tests aimed at verifying the robustness of the application during the data collection process. Our results show that the mobile application is able to reduce the beacon loss rate, with an average value of 77% of collected beacons.

The Bluetooth Low Energy (BLE) technology provides an effective means for indoor location and navigations by using Beacons - BLE devices that can transmit and receive signals over short distances. Device’s information and goods’ information that is linked to a Beacon can be archived by a mobile application, which is basically a Bluetooth - enabled application. In this paper, we present the design and development of an user - driven information IoT system based on the BLE technology. An experimental product, ESMarket, is a system that uses our self - development Beacon - ESBeacon for smart supermarkets with the ESBeacons are placed in a small supermarket shelves and a Bluetooth - enabled smartphone is used to install the digital supermarket application to communicate with these ESBeacons. The results show that when a smartphone appears within the ESBeacon range, it will display information related to the shelves on the screen.

This paper presents our experience on a real case of applying an indoor localization system for monitoring older adults in their own homes. Since the system is designed to be used by real users, there are many situations that cannot be controlled by system developers and can be a source of errors. This paper presents some of the problems that arise when real non-expert users use localization systems and discusses some strategies to deal with such situations. Two technologies were tested to provide indoor localization: Wi-Fi and Bluetooth Low Energy. The results shown in the paper suggest that the Bluetooth Low Energy based one is preferable in the proposed task.

Experience Questionnaire

This project is conducted based on the Nawacita policy from President Joko Widodo. Tourists tend to explore the attraction independently instead of using a tour guide, but there are minimum supporting facilities because of the limitations of detailed information on tourist attraction in various languages that are not interesting and less interactive. The objectives of the research are to develop an Internet of Things based mobile application named eTourGuide that uses a location-based service to get information about the content interestingly and interactively inside a museum. The location-based service uses beacon that broadcast Bluetooth Low Energy (BLE) signal. Development of the research includes several experiments for gathering the data optimally. After completing the development, user experience questionnaire is required to evaluate the result of user’s experience after using the application. The result shows positive results of user’s experience after using the application.
