Haptic technology from the video camera positioned inside the patient's body to perform the procedure. Visual feedback is either similar or often superior to open procedures. The greatest limitation to these minimally invasive approaches is the impairment (in the case of traditional laparoscopy) or complete lack of tactile sensation (in the case of robotic laparoscopy) normally used to assist in surgical dissection and decision making. Despite multiple attempts, no tactile imaging device or probe is currently commercially available for laparoscopic surgery. Figure on the right presents one of the proposed devices, which is in the development phase. Haptic technology Haptic technology or
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
