The paper describes a multimodal guidance system whose aim is to improve manual skills of people with specific disorders, such as Down syndrome, mental retardation, blind, autistic, etc. The multimodal guidance system provides assistance in the execution of 2D tasks as for example: sketching, hatching and cutting operations through haptic and sound interactions. The haptic technology provides the virtual path of 2D shapes through the point-based approach, while sound technology provides some audio feedback inputs about his or her actions while performing a manual task as for example: start and/or finish an sketch; some alarms related to the hand's velocity while sketching and filling or cutting operations. Unskilled people use these interfaces in their educational environment.
