Abstract
A remote commander wherein a user can confirm operation of an operation key after such operation has a touch panel operating section including a display device for displaying an image of a plurality of operation keys thereon and an operation detecting device for detecting, when one of the operation keys displayed on the display device is depressed, the thus depressed operation key. Upon such detection of the depressed operation key, the display device is controlled to display part or all of a display portion of the depressed operation key in a flickering condition for a predetermined period of time after completion of such depression of the operation key. An infrared ray command signal corresponding to such depressed operation key is sent out to a remote object appliance to operate the object appliance.
