It seems like the kind of thing you would set up to run when you are not in the room. The cables appear to stay taut and out of the way when it's not running.

Their example of it being used to move items between robotics stations in an automated workshop seems far more widely-applicable than the in-home solution, which I imagine is primarily aimed at assisting people with physical disabilities rather than those of us who can easily bend down and pick things up without pain or exhaustion.
