Batphone vs KWENDA

Batphone is a research tool which demonstrates a method determining your location within a building. It's meant to be an alternative to GPS or iBeacon, and it works by using the microphone to record room ambience. These acoustic room fingerprints are used to recognize previously-tagged rooms when they are revisited. For comparison, it also shows the position retrieved from Location Services, which determines your coordinates using radio signals from GPS satellites, wifi and cellular base stations. Our experiments have shown that Batphone's acoustic method is more accurate than the radio method. Try it for yourself and let us know what you think! Fore more details, please see the report titled "Indoor Localization without Infrastructure using the Acoustic Background Spectrum" which was presented at the 2011 MobiSys conference.

KWENDA gives you information and guidance. It provides information about the room your in or about the artwork you see on the wall. The system uses iBeacons and is developed by and in conjunction with people with visual impairments that uses VoiceOver. KWENDA respects your needs. If you can't use stairs due to weak legs or you have a guiding dog that can't use escalators just adjust the type of travel in the settings and KWENDA will take this into consideration when calculating navigation routes for you. Get an overview by looking at the map where all the info points are marked and see the navigation route directly on the map. Read more at https://mawingu.se.
