Haptic feedback: a brief history from telepresence to virtual reality
Haptic Human-Computer Interaction, 2001
This paper presents a short review of the history surrounding the development of haptic feedback systems, from early manipulators and telerobots, used in the nuclear and subsea industries, to today's impressive desktop devices, used to support real-time interaction with 3D visual simulations, or Virtual Reality. Four examples of recent VR projects are described, illustrating the use of haptic feedback in ceramics, aerospace, surgical and defence applications. These examples serve to illustrate the premise that haptic feedback systems have evolved much faster than their visual display counterparts and are, today, delivering impressive peripheral devices that are truly usable by non-specialist users of computing technology.
Keynote Address: Haptic Feedback for Virtual Reality
2002
Haptic feedback is a crucial sensorial modality in virtual reality interactions. Haptics means both force feedback (simulating object hardness, weight, and inertia) and tactile feedback (simulating surface contact geometry, smoothness, slippage, and temperature). Providing such sensorial data requires desk-top or portable special-purpose hardware called haptic interfaces. Modeling physical interactions involves precise collision detection, real-time force computation, and high control-loop bandwidth. This results in a large computation load which requires multi-processor parallel processing on networked computers. Applications for haptics-intensive VR simulations include CAD model design and assembly. Improved technology (wearable computers, novel actuators, haptic toolkits) will increase the use of force/tactile feedback in future VR simulations.
Haptic Science and Technology in Surgical Simulation, Medical Training and Military Application
2014
Engineering as it finds its wide range of application in every field not an exception even the medical and military field. One of the technologies which aid the surgeons to perform even the most complicated surgeries successfully is Virtual Reality. And In this paper I have a look at different military fields and applications. I present example applications, which are being used in those fields. The applications are discussed and conclusions are made. Haptics, despite of being a relatively new topic in military field, has a small but certain ground already and will be more important in the future. Even though virtual reality is employed to carry out operations the surgeon’s attention is one of the most important parameter. If he commits any mistakes it may lead to a dangerous end. So, one may think of a technology that reduces the burdens of a surgeon by providing an efficient interaction to the surgeon than VR. Now our dream came to reality by means of a technology called “HAPTIC T...

This study gives a broad overview of haptic technologies for social touch research. In psychology and neuroscience, social contact has received a lot of attention. It is now feasible to make attending in social touch from a particular distance or with the artificial social agents, research into the technology mediated social contract has been motivated by social touch research, and the point of research has been found very effecting that are quite similar to through social touch. Haptics is the research of how to interact with computer applications through touch (tactile) sensation and control. Haptic device gives users a tactile experience in computer-generated environments, making touchable virtual objects appear real and tangible. This method applies pressures, vibrations, and/or movements to the client in order to connect them to a virtual environment through their tactile. The creation of virtual objects items that only appear in computer simulations as well as the locally and remotely control of machinery and apparatus might benefit from this mechanical stimulation. Numerous sectors have previously demonstrated the versatility of haptic technology. Technology has made the possibility that to get truly investigated that how human sense of touch functions by enabling the production of precisely controlled virtual objects. This method might be used to train people for occupations requiring hand-eye coordination, such operating on spacecraft or performing surgery. This kind of input may be used to observe and engage with nanomaterials, and also simulate electrons atom orbits and the feel of abdomen tissue during operation or a laparoscopy training exercise.

Computer haptics is an emerging technology that provides force feedback and tactile sensations to users as they interact with a virtual object. Haptic hardware provides sensory feedback that simulates physical properties and forces. The monitor enables sighted users to see computer generated images and audio speakers allow users to hear sounds, the haptic device makes it possible for blind or visually impaired users to feel force feedback and textures while they manipulate virtual two and three dimensional objects. The haptic device allows the user to interact with a virtual object, such as a planet surface feature or a cell membrane, using the sense of touch. Other physical properties can also be simulated, such as textures, magnetism, viscosity, vibration, or elasticity. Science related haptic software was used with students with visual impairments, the researcher found that adding forces to the visual display enhanced users understanding of the binding energy of a drug molecule. ...
Haptic Systems in User Interfaces
Proceedings of the 2019 ACM Southeast Conference, 2019
Over the past decade, the advancements in force-feedback (haptic) systems, facilitated the inclusion of the tactile communication channel in a variety of user interfaces. Tactile sensors are distributed over the entire human body, hence a diversity of haptic hardware configurations are possible. The applications span from: force-feedback systems-conveying large forces, to vibrotactile systems-conveying smaller forces to the human sensory system. This paper provides a comprehensive survey of state-of-the-art in force-feedback and vibrotactile hardware with references to associated software. The main application domains, several prominent applications, as well as significant research efforts are highlighted. Additionally the survey defines the terms and the paradigms used in the haptic technology domain.

The work in the Touch Lab (formal name: Laboratory for Human and Machine Haptics) is guided by a broad vision of haptics which includes all aspects of information acquisition and object manipulation through touch by humans, machines, or a combination of the two; and the environments can be real or virtual. We conduct research in multiple disciplines such as skin biomechanics, tactile neuroscience, human haptic perception, robot design and control, mathematical modeling and simulation, and software engineering for real-time human-computer interactions. These scientific and technological research areas converge in the context of specific application areas such as the development of virtual reality based simulators for training surgeons, haptic aids for people who are blind, real-time haptic interactions between people across the Internet, and direct control of machines from neural signals in the brain.
Haptics in virtual environments: Taxonomy, research status, and challenges
Computers & Graphics, 1997
Haptic displays are emerging as effective interaction aids for improving the realism of virtual worlds. Being able to touch, feel, and manipulate objects in virtual environments has a large number of exciting applications. The underlying technology, both in terms of electromechanical hardware and computer software, is becoming mature and has opened up novel and interesting research areas. In this paper, we clarify the terminology of human and machine haptics and provide a brief overview of the progress recently achieved in these fields, based on our investigations as well as other studies. We describe the major advances in a new discipline, Computrr Huptics (analogous to computer graphics), that is concerned with the techniques and processes associated with generating and displaying haptic stimuli to the human user. We also summarize the issues and some of our results in integrating haptics into multimodal and distributed virtual environments, and speculate on the challenges for the future.
