Haptic Haptic is a term referring to the technology of touch. One of the earliest forms of haptic devices is used in large modern aircraft that use servo systems to operate control systems. One envisioned use of haptics is for " teledildonics ". www.nebulasearch.com /encyclopedia/article/Haptic.html   (587 words)

Haptic - Wikipedia, the free encyclopedia It is the earliest sense to develop in the fetus, and the development of infants' haptic senses, and how that relates to the development of the other senses such as vision, has been the target of much research. Haptic simulators are currently used in medical simulators and flight simulators for pilot training (2004). Haptics is gaining widespread acceptance as a key part of Virtual Reality systems, adding the sense of touch to previously visual-only solutions such as 'The Wedge' and more recently in laptop-based VR solutions such as the '3D-Mobile Immersive Workstation'. en.wikipedia.org /wiki/Haptic   (1572 words)

Virtual Prototyping This haptic interfacing allows forces of contact to be simulated, such as surface tracing, assembly forces, and grasping. As a haptic interface moves around in the virtual environment, its position has to be monitored for possible interaction with objects. The haptic interface may be holding a virtual part, and the modeled gripper itself has a certain geometry, so arbitrary surface-to-surface minimum distance calculation is required. www.cs.utah.edu /research/areas/immersive/virtual_prototyping.html   (1174 words)

HAPTIC REPRESENTATION OF SCIENTIFIC DATA FOR VISUALLY IMPAIRED OR BLIND Persons A haptic interface is a force feedback mechanism that is used to feel computer generated objects or forces that a remote robot is sensing. Haptic display research is limited, but has been used to increase the immersive effect of virtual reality and scientific exploration such as molecule docking, nanoscale manipulation, and virtual surgery [1,3,10]. In a haptic environment, axes are represented with planes with periodic "bumps" for the tick marks. www.rit.edu /%7Eeasi/easisem/haptic.html   (2779 words)

Algorithms for Haptic Rendering of 3D Objects The goal of haptic rendering is to generate tactual displays of the shapes, hardnesses, surface textures, and frictional properties of 3D objects in real time. Haptic rendering is a major element of the emerging field of computer haptics, which invites comparison with computer graphics. We have already seen various applications of computer haptics in the areas of medicine (surgical simulation, telemedicine, haptic user interfaces for blind people, and rehabilitation of patients with neurological disorders), entertainment (3D painting, character animation, morphing, and sculpting), mechanical design (path planning and assembly sequencing), and scientific visualization (geophysical data analysis and molecular manipulation). www.nasatech.com /Briefs/July03/NPO21191.html   (545 words)

MVC - Haptic Projects and Research It is driven by a dual processor PIII machine which, as the haptic feedback is calculated by a separate process, limits the perfomance degradation of any interactive visuals. As part of National Science Week 2005, MVC was asked by Manchester Museum if we could provide a haptic demonstration to allow the public to "touch" some artifacts that were usually kept under lock and key in display cases. Within thermal sensing, the force is mapped as a haptic vibration sensation and I am interested in the usage of vibration within scientific visualization. www.sve.man.ac.uk /mvc/Research/Haptics   (1276 words)

SDRU: Colwell et al ASSETS paper Haptic devices such as the one used in the current study also have the potential to assist both sighted and blind users in the navigation of the totally virtual environment of the World Wide Web (WWW). Revesz [21] suggested that haptic recognition of objects is not immediate, as it is with vision, but that the perception of parts of an object is followed by a cognitive process through which the whole is constructed. In designing haptic interfaces, designers need to exercise care and not assume that the virtual world will be perceived in exactly the same ways as the real world, particularly given the current limitations of haptic devices which use probes and joysticks. www.psy.herts.ac.uk /sdru/pubs/VE/colwell.html   (5025 words)

Workshop on Haptic Human-Computer Interaction: Call for Papers   (Site not responding. Last check: 2007-10-21) Haptic devices allow users to feel their interfaces and interactions and have the potential to radically change the way we use computers. Haptic interaction is interaction related to the sense of touch - this could be based on force-feedback or tactile devices. The is currently no unified place to present research on general haptic human-computer interaction and so one aim of this workshop is to provide an infomation resource for those interested in the area. www.dcs.gla.ac.uk /~stephen/workshops/haptic   (667 words)

This used to be a fanciful notion, not really having any bearing on reality, but recent developments such as the 'cyber glove' indicate that it might not be so strange a notion. It is not uncommon that the pornography industry is among the early adopters of a new technology; for example, the multiple-viewpoint feature of DVDs was first widely used in pornography, and the internet is notorious for having been so swiftly exploited by those who work in the porn business. www.reference.com /browse/wiki/Haptic   (892 words)

What is haptic? - A Word Definition From the Webopedia Computer Dictionary Haptics is the science of applying tactile sensation to human interaction with computers. A haptic device is one that involves physical contact between the computer and the user, usually through an input/output device, such as a joystick or data gloves, that senses the body's movements. However, because of the nature of a haptic interface, the user will feel the tennis ball in his hand through tactile sensations that the computer sends through the data glove, mimicking the feel of the tennis ball in the user's hand. www.webopedia.com /TERM/H/haptic.html   (233 words)

Hands on Haptics   (Site not responding. Last check: 2007-10-21) Haptic interfaces, such as force feedback and tactile devices, offer the opportunity to present dynamic "visualizations" in a non-visual manner to the sense of touch. The traditional dichotomy drawn between "input" and "output" is often difficult to delineate in manipulation tasks such as moulding with clay, sewing using a needle, or removing the screw cap from a bottle. The first day of the workshop will emphasise the use of haptic demos provided by the attendees, as this is a vital aspect of the workshop that would not be possible during a paper session or with a larger gathering of attendees. www.dcs.gla.ac.uk /haptic   (454 words)

IMSC [USC Integrated Media Systems Center] In many applications of haptics it will be necessary for users to interact with each other as well as with other objects. The basic idea is to provide a framework for multiple users (each with his or her own haptic device connected to a computer) to share a common experience of touch. The key challenge is the design of an architecture for haptic collaboration via the Internet that explicitly addresses the issue of latency (communication delay), thus providing a foundation for a shared haptic experience among distributed users. imsc.usc.edu /research/project/haptics   (488 words)

Haptic Devices Product Resources   (Site not responding. Last check: 2007-10-21) A haptic interface is a device which allows a user to interact with a computer by receiving tactile feed back. The use of haptic devices that once were cost prohibitive but now are incorporated into mainstream devices such as the iFeel Mouse and the IFeel Mouseman, promote inclusion and acceptance of "adaptive" technology into the "daily computer experience" of people with and without disabilities. The 2-demensional haptic devices can be used to aid computer users who are blind or visually disabled; or who are tactile/Kinesthetic learners, by providing a slight resistance at the edges of windows and buttons so that the user can "feel" the Graphical User Interface (GUI). snow.utoronto.ca /technology/products/haptic-devices.html   (438 words)

.::The Tacitus Project::. Haptic interfaces have previously been employed with 2D and 2.5D desktop metaphors in order to improve targeting performance. Subjects completed a targeting task with and without haptic feedback, in the form of "virtual magnets" that physically attract the user towards targets in the environment, and with and without the provision of stereo depth cues via a stereo emitter and shutter glasses. An important application of haptic interface technologies is to allow domain experts to transfer manual skills to virtual environments. www.eca.ac.uk /tacitus/papers.htm   (866 words)

Using the TBG Haptic Device Rest the haptic pointer in its neutral position (centered, on the table, pointing forward).

Haptic Rendering of Molecular Properties The principal goal of this research is design of a haptic interface that allows the user to modify shape of a molecular model (eg, to rotate a particular bond) while ‘feeling’ the required energy via force resistance. Driving a haptic device requires fast computation of the model - in order to create illusion of smooth surfaces etc., the force has to be recomputed at the rate 1—3 kHz. However, as the science behind haptic interfaces is very premature, a lot of effort is still needed to fulfill the primary expectation, ie, to provide an effective interface to huge data sets emerging from scientific calculation. www.ercim.org /publication/Ercim_News/enw44/krenek.html   (725 words)

Researchers use haptics á the science of touch á to 'feel' objects that don't exist: 4/03 Haptics, the science of touch, lets computer users interact with virtual worlds by feel. Haptic interfaces can communicate the contours of a sculpture, and they can apply pressure to sculpt. With this new two-fingered haptic interface, researchers can pick up a virtual block, and then let it slip controllably between their fingers. www.stanford.edu /dept/news/pr/03/haptics42.html   (864 words)
