CityGuide

The device operates quite simply; using the Sony Spresense’s onboard GNSS module, it retrieves the current location of the individual and processes it in order to see if they are at a certain landmark on the map. If the user is at a marked location; the appropriate recording for the landmark will be played, briefly informing the client about the background to what they are seeing.
