AR-based next-gen maps aim to rebalance detail and simplicity
Every sat-nav user is familiar with the chagrin of missing their turn because the map’s lines and circles don’t resemble the real world.
Yandex is blaming maps, not users, for these errors. At its annual conference in December, the company presented its re-designed maps boasting natural-looking 3D objects such as trees, bus stops, colored buildings, road markings and more. “We know that many users are bad at translating physical reality into a system of symbols,” Ilya Vlasyuk, head of map production of Yandex, said in the company’s video release. “Therefore, improving readability of maps is our job. One of the ways to achieve it is to increase the level of detail in the maps.”
However, many other popular navigation apps also offer similar enhancements. For example, Sygic and TomTom’s apps have embedded 3D views of buildings. Both, as well as Google Maps and Petal Maps, also accurately reproduce the design of motorway lanes and markings at busy locations. Yet, none of them offer the full range of native-looking objects embedded in Yandex’s next generation of maps.
Native images are a compromise
That said, adding more native-looking objects to sat-nav apps can be a double-edged sword, believes Andrey Vorobyev, deputy head of ITS competence center of the Moscow Road Institute (MADI). First, the more detail in the map, the more time it takes the commuter to sort out unimportant elements. Also, large 3D objects such as tall buildings or trees can block the view of smaller ones behind them.
However, a bigger issue is that any map, good or bad, distracts the driver from the road, he said. While improving readability can reduce distraction time, it cannot eliminate it totally because looking at the map involves taking one’s eyes off the road and re-focusing them. This inherent disadvantage can only be overcome by getting rid of maps altogether.
An alternative is provided by voice and haptic assistants, which do not distract the user from the road. However, their instructions are not precise enough, leading to navigation mistakes on complex road junctions.
AR-based navigation is the final goal
Vorobyov suggested that the ultimately solution to these issues will be the development of navigation tools based on holographic head-up displays for cars and augmented-reality wearables for cyclists, scooter riders and walkers.
