An input interface device includes at least one processor. The processor performs control to cause, among light emitters, a first light emitter corresponding to a contact/proximity point detected by a detector to emit light with a luminous intensity higher than that of a remaining light emitter. The contact/proximity point is where an object is in contact with or in proximity to a detection surface. The processor further performs control, while the object is moving along the light emitters in a state in which the object is in contact with or in proximity to the detection surface, to gradually reduce a luminous intensity of, among the light emitters, a second light emitter corresponding to a point where the object being in contact with or in proximity to the detection surface once detected by the detector is no longer detected to put out the second light emitter in a predetermined time.

A display apparatus includes an image pickup section, a display section, an instruction section, a position specification section, a direction specification section, a specification section, and a reporting section. The image pickup section sequentially picks up an image. The display section displays the picked up image. The instruction section generates an instruction signal for marking an object included in the image. The position specification section specifies a position where the display apparatus exists. The direction specification section specifies a pickup direction by the image pickup section. The specification section specifies a position of the object relative to the position of the display apparatus based on the position of the display apparatus and the pickup direction in response to the instruction signal. The reporting section reports the position of the object.
