Abstract
According to one configuration, a remote controller device wirelessly controls a remote media system. The remote controller device includes multiple selectable control buttons, multiple optical sources, and controller hardware. Each optical source individually back-illuminates a respective selectable control button of the multiple selectable buttons. The controller hardware selectively activates different groupings of the multiple optical sources depending upon a current operational mode of the remote media system. For example, a respective user of the remote controller device selects a particular button of the remote controller device corresponding to the first operational mode. The remote controller device, in turn, transmits a wireless signal to the remote media system to control the remote media system to the first operational mode. Rather than illuminating all buttons, the remote controller device then back-illuminates only a relevant group of multiple selectable control buttons applicable to the first operational mode.
