Abstract
An impact force feedback device and an interactive system using the same are provided, wherein a large impact force feedback is generated to provide a real force feedback sensation to the user. The impact force feedback device includes a housing, a magnet, and at least one actuator assembly. The housing carries the actuator assembly. The actuator assembly includes a guide rod device, a mass, and a coil. The guide rod device is disposed on the housing. The mass is disposed on the guide rod device in a sliding manner. The coil generates an electric field when a current is conducted through it. An electromagnetic force is generated by supplying the current in a direction orthogonal to a magnetic field. The electromagnetic force is supplied to the mass such that the mass moves on the guide rod device and impacts the housing to generate the unidirectional impact force feedback.
