![]() ![]() Bluetooth beacons broadcast a Bluetooth Low Energy (BLE) signal in a limited and configurable range. A mobile application that resorts to Bluetooth beacons for indoor user localization and Building Information Models (BIM) for physical context. This study employs two established technologies to develop a cost-effective solution. A second problem is that indoor maps with relevant, usable information that can be integrated easily in digital apps are usually not available. An Indoor Positioning System usually implemented via Bluetooth, infrared, magnetic field and/or WIFI, serves the purpose of finding the position of an electronic device-phone, tablet, watch-and, when the smart device connects with the ILS, the system can store that data and use it to inform on the building utilization. This life-problem can be easily solved by an Indoor Location System (ILS). ![]() Indoor navigation based on smartphones has been attempted and provides a number of challenges. GPS and inertia based mobile apps are today ubiquitous in outdoor navigation, but GPS is not available indoor. It is of the interest of building owners to help users. Users usually choose to wander and explore on their own, then ask for directions and sometimes get lost again. Since environmental cues such as sunlight are missing, signage-based orientation, maps, and human-assistance are the traditional methods of orientation. Even when spatial clarity is built into the design, adaptations introduce entropy and compromise the initial intention. The application was tested by a panel of new and habitual campus users against traditional wayfinding alternatives yielding navigation times about 30% smaller, respectively.īuildings such as hospitals, schools, shopping centers, or transportation interfaces are increasingly large and complex and therefore hard to navigate efficiently, both for occasional and frequent users. Also, the beacons can deliver relevant context information. This system is based on an App (Find Me!) for Android OS (Operating System) which captures the Bluetooth Low Energy (BLE) signal coming from the beacon(s) and shows, through a map, the location of the user’s smartphone and guide him to the desired destination. This uncertainty is handled by building layout and users’ movement in a developed system that maps users’ position, gives guidance, and stores user movements. Beacons installed on the building at specific pre-defined positions emit signals that give a geographic position with an associated imprecision, related with Bluetooth’s range. This is an interactive process with visualisation information that can help user’s orientation inside unknown buildings and the data stored from different users can provide useful information about users’ movements inside a public building. The author company, Premier Biosoft has also launched a simple version for evaluation of oligos for real time PCR primers and probes (support limited to TaqMan and SYBR Green primers) by the name Beacon designer free version.This research work uses a simplified approach to combine location information from a beacon’s propagation signal interaction with a mobile device sensor (accelerometer and gyroscope) with local building information to give real-time location and guidance to a user inside a building. Avoidance of the cross homology renders specificity to the primers in question and they are highly targeted and only amplify the intend sequence and no other targets.īeacon Designer has been used in workshops and conferences related to real time PCR study as a reference software. The software designs real time pcr primers and probes for complex differential gene expression and allele discrimination assays. ![]() The software currently supports the following real time PCR chemistries for efficient primer and probe design.īeacon Designer program has built in support for homology avoidance using the standard web BLAST service or the set-up of a desktop BLAST feature for identification of regions that are significantly cross homologous with the target gene sequence. It is compatible to work on Windows as well as on Mac. ![]() Beacon Designer designs highly specific an efficient primers and probes for real time PCR (polymerase chain reaction) assays. ![]()
