Haptic feedback method, haptic feedback apparatus, electronic device and stylus

A haptic feedback apparatus, applicable to an electronic device including a touch input unit configured to receive an operation on the touch input unit by an operating object, wherein the haptic feedback apparatus comprises:

• a force feedback unit arranged on the touch input unit;
• a circuit board;
• a processing unit arranged on the circuit board, wherein the processing unit is configured to obtain a first parameter indicating a type of the operating object upon reception of the operation and to determine a feedback parameter of the force feedback unit at least based on the first parameter;
• and
• a control unit arranged on the circuit board, wherein the control unit is configured to control the force feedback unit based on the feedback parameter to generate and output to a user a feedback force corresponding to the type of the operating object.

A stylus, configured to control an electronic device by performing an operation on a touch input unit, wherein the stylus comprises:

• a body comprising a head and a stem;
• a force feedback init arranged on the body;
• a circuit board arranged on the body;
• a processing unit arranged on the body, wherein the processing unit is configured to obtain a first parameter indicating a type of the stylus when the operation is performed on the touch input unit by the head and to determine a feedback parameter of the force feedback unit at least based on the first parameter;
• and
• a control unit arranged on the circuit board, wherein the control unit is configured to control the force feedback unit based on the feedback parameter to generate and output to a user a feedback force corresponding to the type of the stylus.
