Communicating with Collision System in ECS

[SET001]

I have read tons of articles and forums threads about ECS but still can't understand how anything in engine should communicate with Collision System. Let's say I have Input System that handle keyboard input and then at some point it want to move player character forward. Before doing this I should ask Collision System if there would be a collisions after that move and only if no - change position. 

 

My current approach is to have requestTranslation function in CollisionSystem that take translation function and object like this:

moveForward(){	V3.CollisionSystem.requestTranslation(this.mesh, function(object){		object.translateZ(-this.movingSpeed);	}.bind(this));}

What do you think about this approach? How good/bad it is? What are know alternatives?
