In one embodiment, a method includes displaying a horizontal screen visible to a user through a display, determining a horizontal distance between a position of the user and the horizontal screen, determining a vertical distance between a controller associated with the user and the horizontal screen, creating an interaction screen, where the interaction screen and the horizontal screen intersect in a closest point, where the interaction screen is tilted toward the user from the horizontal screen by an angle, detecting a first event that a ray cast from a virtual representation of the controller hits a first point on the interaction screen, translating the first event to a second event that the ray cast hits a second point on the horizontal screen, and displaying a curved line from the controller to the second point on the horizontal screen that is visible to the user through the display.
