Not everyones hands are the same. One way to beat repetitive motion problems like tendonitis and arthritis is to make it so your fingers are not always stuck in one place on the controller. I am not much of a gamer but since buying quest I have played dead and buried 2 an hour or 2 a day and my left thumb is in agony. One way to prevent this would be a moveable (sliding) joystick that can slide along a rail and lock in place to provide the most comfortable position for each person.
