In the Google Map Tour video, Google Maps uses the Redundancy Principle to explain the new features that were added. It uses a multimedia presentation with narrations and animations and goes through the process and examples of using Google Maps. The video explains how personalization can be used by being logged into your Google account. Users can "search, star places, and publish reviews" and will get more recommendations to places Google Maps thinks would interest them.
Another principle that Google Maps uses is the Personalization Effect. The narration that is recorded for the audience to hear is a step by step conversational style tutorial. Google Map users can use different features such as "street view", or "photo view" to zoom in see the street or pictures of the location that has been submitted to Google. Another feature that has been added is "earth view." This allows users to "bring the 3D experience from Google Earth to Google Maps." With a video tutorial, the narrator explains how to use the new features and views that have been installed into Google Maps.
Along with Google Maps, there are apps that use interactivity. The Android app Skyvi uses voice activation to help find nearby places of interest for the mobile user. App users can give a voice command into their android phone asking where find a certain place of interest and Skyvi will give a "voice guided, turn-by-turn directions from Google Maps. Skyvi users can also update their social networking statuses by using the voice activation.
