摘要

PURPOSE: An apparatus utilizing electromagnetic Induction based on reaction upon external force for providing a passive haptic feedback, a module providing passive haptic feedback using the same, a portable unit using the same and a control method therewith are provided to supply to a user a haptic feedback corresponding to measured external force by measuring the strength of external force through an electric signal within a second magnetic generating unit. CONSTITUTION: A first magnetism generating unit(30) is connected to a lower portion of a pressure plate(20), and generates magnetic force. An elastic force supply unit(40) provides the pressure plate with elastic force. A second magnetism generating unit(50) generates an electric signal through an electromagnetic induction effect of the first magnetic generating unit, and generates magnetic force. A measurement unit measures the strength of the external force through the generated electric signal.
