Gaming-related displays present text and graphics viewable with a special visual aid, e.g., a camera phone. The visual aid provides an interface allowing the player to interact with, and be engaged by, the gaming machine and the gaming environment. The text and graphics shown on the visual aid may provide information that adds to the player's experience. For example, a gaming system includes a gaming terminal for a wagering game. The gaming terminal includes a light-emitting area emitting a predetermined pattern of invisible light having wavelengths outside the visible electromagnetic spectrum. The gaming system also includes a visual aid including a sensor and a visual aid display. The visual aid detects, with the sensor, the pattern of invisible light, converts the pattern of invisible light into a pattern of visible light having wavelengths inside the visible electromagnetic spectrum, and displays the pattern of visible light on the visual aid display.
