Title:
【発明の名称】ターンアラウンド型のセルラ式電話機
Document Type and Number:
Japanese Patent JP2003523142
Kind Code:
A
Abstract:
A miniaturizable wireless communications device is configured to redefine the roles of the primary front and rear surfaces of the device by positioning a large graphic display on the forward surface and a speaker on the rear surface. The associated keypad can be disposed on either or both of the rear surface or the graphic display (such as via a touchscreen). Alternatively, a pivotable flip can include the keypad and even the microphone. During operation, a user can turn the device around to orient the desired input surface for use (forward face up for display surface use and forward face down or away for telephone use). An associated method of designing the operational platform of a wireless communications device so that it has two active primary faces is also disclosed.
