We propose a wearable haptic display that indicates the pressure and vibration on the palm for bimanual operations in virtual reality environments. This system aims to provide the touch and stroke sensations of virtual objects or virtual creatures. We constructed a prototype device that can reproduce vertical and shearing forces on the palm and evaluate the capability of the proposed method to ...

Haptic technology, or haptics, is a tactile feedback technology which takes advantage of a user's sense of touch by applying forces, vibrations, and/or motions upon the user. This mechanical stimulation may be used to assist in the creation of virtual objects (objects existing only in a computer simulation), for control of such virtual objects, and for the enhancement of the remote control of m...

Current touch technology provides precise and accurate large multi-touch surfaces, which allow multiple users to collaborate in these two-dimensional setups. Furthermore, recent developments in the field of display technology support visualization of three-dimensional (3D) virtual environments (VEs) in high-fidelity visual detail on these surfaces. Finally, cost-efficient depth cameras such as ...

Of the processes that make up a transaction of selling a physical product for money over the Internet, those that presume some form of physical product handling are most problematic. These include the process of determining product utility and the delivery phase. The difficulties that the latter poses for the spread of on-line shopping and e-commerce-enabled disintermediation are well known, wh...

Liver fibrosis assessment is very important to the treatment of chronic liver disease. In the present study, Virtual Touch Tissue Quantification (VTQ) and eSie Touch™ elasticity imaging techniques were used to examine the rat liver fibrosis model. Rat liver fibrosis was induced with thioacetamide and the degree of liver fibrosis was determined using pathological diagnosis as a gold standard. Th...

The continuing emergence of virtual reality (VR) for training, industrial and entertainment applications increases the need for highly capable haptic interfaces into these VR environments. For certain subsets of tasks in these application areas, existing methods for interfacing haptic devices to VR applications suffice. However, for operators performing manual control tasks, many of the pre-exi...

Introduction: Medical images generated in MRI are loaded with large amounts of information, posing challenges for human sight to identify and perceive the level of detail provided within these images. A solution is to use additional senses, such as the sense of touch, which is known as haptics. Haptics is also referred to as the technology of generating artificial sense of touch by interacting ...
