摘要： The present invention provides a haptic feedback device comprising a touch-sensitive display screen (1) and a magnetic loop actuator (2). The touch-sensitive display screen (1) has a touchable surface coated with a transparent film which is able to provide a variable surface friction to the touchable surface in response to an externally applied electromagnetic field. The magnetic loop actuator (2) is for applying the electromagnetic field to the film to vary the surface friction of the touchable surface. The magnetic loop actuator (2) is spatially separated from the touch-sensitive display screen (1). In a preferred embodiment, the haptic feedback device further comprises a driver module (12) to drive the magnetic loop actuator (2) to generate the electromagnetic field, a triggering module (17) to trigger the driver module (12), and an application (18) to receive a user input from the touch-sensitive display screen (1), to determine a haptic output to the user in response thereto, and to output a control signal to the triggering module (17) to vary the surface friction of the touchable surface according to the haptic output thus determined. The touch-sensitive display screen (1) and the magnetic loop actuator (2) may be installed as separate components in an electronic device (4) or the magnetic loop actuator (2) may be maintained external to an electronic device (4) comprising such a touch-sensitive display screen (1). In this way, the surface friction of the touch-sensitive display screen (1) may be varied to provide haptic feedback to a user without requiring a special construction of the touch-sensitive display screen (1).
