Haptics is the science of applying touch (tactile) sensation and control to interact with computer applications. Haptic device gives people a sense of touch with computer generated environments, so that when virtual objects are touched, they seem real and tangible. Haptic technology refers to technology that interfaces the user with a virtual environment via the sense of touch by applying force...

In this paper, we present a stereoscopic kiosk for virtual museum, which combines techniques of stereoscopic displays, image-based rendering, virtual reality, and augmented reality. In our kiosk system, artifacts are presented as object movies, and can be integrated with both image-based panoramas and geometry-based scenes for constructing virtual museum. Two display devices are used in the kio...

In this paper, we discuss the development of cost effective, wireless, and wearable vibrotactile haptic device for stiffness perception during an interaction with virtual objects. Our experimental setup consists of haptic device with five vibrotactile actuators, virtual reality environment tailored in Unity 3D integrating the Oculus Rift Head Mounted Display (HMD) and the Leap Motion controller...

This paper addresses the ongoing developments of a haptic (in fact multi-modal) framework called I-TOUCH, which serve two purposes. The first purpose is academic and concerns the conception of a generic framework that is able to allow researchers in haptics to prototype quickly computer haptic algorithms and to do quantitative and qualitative evaluations of their concepts. Nevertheless, the fou...

OBJECTIVE The purpose of this study was to evaluate the diagnostic performance of a novel quantitative shear wave elastography (SWE) of virtual touch tissue imaging quantification (VTIQ) in diagnosis of breast lesions. METHODS The conventional ultrasound (US) and VTIQ images of 133 pathologically proven breast lesions in 98 patients were assessed. The breast lesions were classified by US brea...

3d imagination of human's organs has become feasible by digital image processing techniques and algorithms via ct or mri images in recent years. in this study, a new method for reverse engineering and biomodelling of hard tissues by catia cloud points' concept has been considered. comparing with the current softwares (e.g. biobuild or mimics) has shown the new method's easiness of implementing ...

BACKGROUND Objective of the study was to evaluate the diagnostic value of novel ultrasonographic modalities in comparison with simultaneously performed liver biopsy. METHODS The results of simultaneously performed examinations using Acoustic Structure Quantification (ASQ), Virtual Touch Imaging and Quantification (VTIQ) and Virtual Touch Tissue Quantification (VTTQ) were compared with the fin...
