How to Increase Pose Movement Speed in ARCore

I am working on an application in Unity ARCore SDK for visualizing a room with marker detection on android mobile phones. There is no problem in creating the room model when marker is detected. The problem is, when user moves in the room, its movement is very slow in the unity world. For instance when user moves 5 meters in real world, its position on the model just changes 1 meter. How can i increase the change in position?

I can't scale down the size of the model. Because when i do that, the model not aligns with the real world, it becomes much much smaller.
