An electronic controller apparatus (30) having an input device (36) coupled to a display (34) can include a motion detector (40) and a means (42, 44, 46, 48, and 50) for maintaining the display in a predetermined orientation relative to a user of the electronic device and regardless of the movement of the input device. The movement of the input device causes a signal to vary in the electronic controller apparatus. The electronic controller can be a hand held device such as a game controller, a personal digital assistant, a cellular phone, a remote control device, or a gaming adaptor for a personal digital assistant or for a cellular phone. The means for maintaining the display in the predetermined orientation can use gravity to maintain the predetermined orientation or alternatively use electronic sensors (104 and 105) and motors (108 and 110) to maintain the predetermined orientation of the display.
