Do any of you fine gentlepeople know of a good way to alert a person in VR that you want their attention?

I am trying to get back into VR. It's great cardio.

I want my wife to be able to say "I'm going to bed, goodnight" without risking me smashing her face while I smash the face of a goon in GORN.

Is there an adhesive "doorbell" I can place on my doorframe that activates a vibrating wristband? Or activates an LED small enough to fit inside my headset? I cant find anything in that direction more refined than a Ring doorbell.

I could say "just yell" but its night time and our walls are thin.

My leading solution is supply a basket of plushies and tell her to throw one at my knees before bedtime, hoping that doesn't make me trip or something.

Anyone got better solutions?
