Introduction
When we want to go to an unknown location, we will use maps to navigate. In the era when the global positioning system was not popular, people used paper maps. With the development of science and technology, almost all modern navigation systems use the Global Navigation Satellite System (GNSS), and many countries have developed their own positioning systems, among which Global Positioning System (GPS) is more commonly used. GPS will use trilateration to locate the user's current location and set the path to the destination. GPS positioning is used when outdoors.
Why we need indoor positioning system (IPS)?
However, in the indoor environment, it is difficult for GPS to provide reliable positioning information due to signal attenuation and blocking caused by buildings and construction materials. Thus the location-based apps such as Navigation don’t work inside airports, malls, subways, etc. GPS doesn’t provide information about the floor and building level where the user is located. These factors led to the need for a system where a user can be located inside a building accurately and precisely to make positioning and navigation inside indoors as easy as outdoors.

Association of indoor positioning system (IPS) and AR remote instructions system.
This is the previous blog about AR remote instruction.
AR Remote Instructions base on ARKit - フレクトのクラウドblog re:newal
In AR remote instruction, the supporter or the client will have a problem, that is very often unable to find the target location and cannot provide assistance. Almost all locations are indoor environments, such as warehouses or offices.
Therefore, we searched some existing research information to investigate which research methods are suitable for AR remote instruction.
