Editor's Notes

- Bringing Location Indoors, Ben Butchart, EDINA Indoor Positioning Technology is rapidly emerging as a mainstream mobile technology. Apple recently incorporated Indoor Positioning into iOS8 and Apps using “nearables”, based on Apple’s iBeacon technology are gaining traction and media attention. Goal for today is to share EDINAs experience experimenting with indoor technologies such as iBeacons and report on potential use case in higher, further education and skills sector.
- Indoor Location relies on fusion of multiple sensors such as WIFI, GPS, motion sensors. Motion sensors such as accelerometer, gyroscope, magnetometers provide dead reckoning ( count footsteps and direction), environmental sensors such as barometer (altitude), mobile cell. Dedicated infrastructure such as iBeacons can also be provided. Floor plan topology can assist in filtering noise in RF signals and interpreting users movements. Users themselves can be part of solution by crowd sourcing pathways through the building.
- (wikipedia entry for iBeacons 20.02.2014) An iBeacon deployment consists of one or more iBeacon devices that transmit their own unique identification number to the local area. Software on a receiving device may then look up the iBeacon and perform various functions, such as notifying the user. Receiving devices can also connect to the iBeacons to retrieve values from iBeacon's GATT (generic attribute profile) service. iBeacons do not push notifications to receiving devices (other than their own identity). However, mobile software can use signals received from iBeacons to trigger their own push notifications

- Some use cases We will revisit these at the end of my talk and hopefully add a few or expand on them. But can see very broad range of applications.
- Now possible for venues such as shopping malls, airports and galleries to upload maps to Apple Maps and Google Maps and for developers to make use these maps. At the moment, Apple and Google are prioritizing large, public venues. As the link to the Google video shows, uploading a floor plan and making align with the map is not difficult, but not trivial either. https://www.youtube.com/watch?v=pR7lFsNFEjg
- We experimented with iBeacons in our office. The screenshots show how we integrated our office floor plan into Open Street Map and used iBeacons to highlight rooms. Issues include usability of standard floor plans Technical issues; Variability in signal strength due to obstacles Variability across devices Smoothing to correct variabilty causes delays use weighted rolling average Multiple beacons 4. Ranging only works in foreground. The link below provides a nice summary from Thoughtworks team who ran a similar but slightly more thorough investigation http://www.thoughtworks.com/insights/blog/semi-technical-lowdown-working-ibeacons
- An intern helped us to design a more accessible version of the floor plan Architectural floor plans are not especially easy for people to make sense of – especially on a small screen. Venue maps often not geographically accurate.
- Projecting the map from standard birds eye view to a zoomed in 2.5d view helps user to orientate themselves more easily.
- Ok – you learnt something about indoor location. Now it’s your turn to come up with some ideas for using them in your institution.
