<p>A display system (1) displays objects (D to F) in a display region (810) in a manner arranged in a predetermined orientation. One light-emitting element of a sensor array (30) emits light to the obj ects (D to F) in the predetermined orientation. The display system (1) prestores data which associates numerical value ranges different from each other with the objects (D to F), respectively. When light reflected by a finger (910) is received by light-receiving elements of the sensor array (30), the display system (1) calculates the number of the light-receiving elements that have received the reflected light, identifies one object associated with the numerical value range including the calculated number of the light-receiving elements, from among the objects (D to F), based on the calculated number of the light-receiving elements and the stored data, and performs processing corresponding to the identified object.</p> |
