VISUAL POSITIONING SERVICE or VPS
Now GPS is over it .So new visual system in Google Maps introduced visual Positioning System (VPS) feature. The VPS uses your phone’s camera and Google’s extensive back-end data to analyze your surroundings to identify where you are with greater accuracy.
A few members of our team members are already cheering about this. They live in densely populated urban areas with tall buildings and often complain of GPS drift and other hassles when navigating. The new visual systems are made just for people like them.
At the may Google I/O conference, senior director of product Aparna Chennapragada showed how Google is “combining the power of the camera and computer vision with Streetview and Maps to reimagine walking navigation.” In her presentation, Chennapragada noted how users would often have to move around in the real world to line themselves up with the blue dot marking their location in Maps. To avoid any such confusion, Google Maps will instead display blown-up 3D directions such as lit-up arrows and precise steps like “6th street is 100 feet away.” Meanwhile, a smaller version of the traditional Maps experience will be displayed on the lower half of the screen, should it be needed. Additionally, the demo showed that panning the camera around the streets would automatically highlight points of interest nearby, such as cafés or retail stores. Finally, Chennapragada said that “just for fun,” the Maps team has also been experimenting with a digital avatar that can help further guide users, with a cartoon fox shown off as an example.
