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 haptic vests or haptic suits for use in immersive virtual reality so that explosions and bullet impacts can be felt. Research has been done to simulate different kinds of taction by means of high-speed vibrations or other stimuli. One device of this type uses a pad array of pins, where the pins vibrate to simulate a surface being touched. While this does not have a realistic feel, it does provide useful feedback, allowing discrimination between various shapes, textures, and resiliencies. Several haptics APIs have been developed for research applications, such as Chai3D, OpenHaptics, and the Open Source H3DAPI. Haptic interfaces
