Haptic technology and expressiveness of the bow (haptic device) held by the artist. This can be done with physical modeling synthesis. Designers and modellers may use high-degree-of-freedom input devices that give touch feedback relating to the "surface" they are sculpting or creating, allowing faster and more natural workflow than traditional methods. Artists working with haptic technology such as vibrotactile effectors are Christa Sommerer, Laurent Mignonneau, and Stahl Stenslie. Digital drawing or handwriting tasks can be enhanced and produce better outputs with a more realistic feedback which is designed to enable artists or writers to feel as if they are drawing or writing
Haptic technology world via a tool or stylus, giving a form of interaction that is computationally realistic on today's hardware. Systems are being developed to use haptic interfaces for 3D modeling and design that are intended to give artists a virtual experience of real interactive modeling. Researchers from the University of Tokyo have developed 3D holograms that can be "touched" through haptic feedback using "acoustic radiation" to create a pressure sensation on a user's hands (see future section). The researchers, led by Hiroyuki Shinoda, had the technology on display at SIGGRAPH 2009 in New Orleans. Several companies are making full-body or torso
