In practical applications, the infrared light receiving module 26 can be activated by operating a function menu of the portable device 200 or by executing a specific program. In this embodiment, a shooting game program is executed as an example. When the shooting game program is started, the portable device 200 activates the infrared light receiving module 26A to receive the infrared light beam R. As shown in step S2, the operation method of this embodiment is followed by displaying an icon using the display screen 250. Please refer to Fig. 4A, which shows a schematic diagram of the display screen when the icon is displayed. In this embodiment, the icon p is a to-be-shot object. For example, the flying-panel P is displayed on the display screen 250 with a display coordinate value range for indicating the position of the icon P on the display screen 250. After the portable device 200 displays the icon p via the display screen 250, the icon p can then be moved on the display screen 250 such that the icon p is shifted to change its display coordinate value range over time. As shown in step S3, the infrared beam r is then emitted toward the display screen 25A. Please refer to item 4B, which shows a schematic diagram of the infrared light beam on the display screen. In the portable device 200 of the present embodiment, the infrared beam R is emitted by the infrared beam emitter 291 of the stylus 290, and the infrared beam R is incident on the display screen 250. As shown in step S4, the infrared beam r is received using the display screen 25A.
