Abstract: The present invention is directed to a psychological counseling assistive system employing immersive virtual reality (VR) and interpersonal relationship sculpture comprises an interpersonal relationship sculpture construction module and a VR experience module. The interpersonal relationship sculpture construction module comprises an interpersonal relationship sculpture construction basic function module and an interpersonal relationship sculpture construction interaction module. The VR experience module comprises a VR experience function module and a role interaction function module. A VR technique and an interpersonal relationship sculpture technique are combined to allow a visitor to have an immersive experience of an embodiment of a psychophysical field. A character model is used to implement an interpersonal relationship sculpture function that would normally require multiple participants in conventional group psychological intervention.
