“…Moreover, Israr et al [14] explored the possibility of enhancing gameplay using a glove containing one vibrating actuator to enrich storytelling through tactile feedback [16]. Beyond gaming purposes, tactile feedback had also been considered for simulators [34,37,43] learning Reading et al [31], Santos and De Carvalho [33], and teleoperation systems [17, 26, 27, 29? ].…”

Apparent tactile motion has been shown to occur across many contiguous part of the body, such as fingers, forearms, and back. A recent study demonstrated the possibility of eliciting the illusion of movement from one hand to the other when interconnected by a tablet. In this paper we explore intermanual apparent tactile motion without any object between them. In a series of psychophysical experiments we determine the control space for generating smooth and consistent motion, using two vibrating handles which we refer to as the Hand-to-Hand vibrotactile device. In a first experiment we investigated the occurrence of the phenomenon (i.e., movement illusion) and the generation of a perceptive model. In a second experiment, based on those results, we investigated the effect of hand postures on the illusion. Finally, in a third experiment we explored two visuo-tactile matching tasks in a multimodal VR setting. Our results can be applied in VR applications with intermanual tactile interactions.

“…Using a unique approach, Sorensen et al [10, 11] gathered structural data directly from images of a sectioned cadaveric head. Digital images were acquired of a cryosectioned head at 25micron thickness creating a ultra high resolution data set composed of 605 RGB images with in plane resolution of 3056 x 2032 pixels aligned with custom registration software.…”

“…In most instances, computer-based simulation accomplishes this by 3D reconstruction of the regional anatomy using data from clinical imaging. Others have employed high-resolution photography utilizing data from specialized cadaveric preparations, including data from the National Library of Medicine’s Visible Human Project and the Visible Ear Project [10, 11]. Some have employed methods to extract polygonal surfaces from these data, while others have created representations using volumetric techniques.…”

Integration of high-resolution data for temporal bone surgical simulations

et al. 2016

Purpose To report on the state of the art in obtaining high-resolution 3D data of the microanatomy of the temporal bone and to process that data for integration into a surgical simulator. Specifically, we report on our experience in this area and discuss the issues involved to further the field. Data Sources Current temporal bone image acquisition and image processing established in the literature as well as in house methodological development. Review Methods We reviewed the current English literature for the techniques used in computer-based temporal bone simulation systems to obtain and process anatomical data for use within the simulation. Search terms included “temporal bone simulation, surgical simulation, temporal bone.” Articles were chosen and reviewed that directly addressed data acquisition and processing/segmentation and enhancement with emphasis given to computer based systems. We present the results from this review in relationship to our approach. Conclusions High-resolution CT imaging (≤100μm voxel resolution), along with unique image processing and rendering algorithms, and structure specific enhancement are needed for high-level training and assessment using temporal bone surgical simulators. Higher resolution clinical scanning and automated processes that run in efficient time frames are needed before these systems can routinely support pre-surgical planning. Additionally, protocols such as that provided in this manuscript need to be disseminated to increase the number and variety of virtual temporal bones available for training and performance assessment.

“…Most VR temporal bone simulators use a volumetric model that supports haptic interaction for drilling with force feedback and uses different technologies to accomplish 3D stereo graphics. VR simulators are based on either CT-derived data (Voxel-Man 26 , the Ohio State University 27 , the Stanford BioRobotics lab 28 , and the University of Melbourne 29 ), or on cryo sections of a fresh frozen human temporal bone (Visible Ear Simulator 30, 31 ).…”

Synopsis This review presents a summary of the current activity of simulation training for otologic skills. Simulation training has been demonstrated in a large spectrum of skills from simple otoscopy to advanced temporal bone surgical procedures and these are individually addressed. There is a wide variety of educational approaches, assessment tools and simulators in use including simple low cost task trainers to complex computer based virtual reality systems. A systematic approach to otologic skills training using adult learning theory concepts such as repeated and distributed practice, self-directed learning, and mastery learning is necessary for these educational interventions to be effective. Future directions include development of valid, universally accepted measures of performance to assess efficacy of simulation training interventions and for complex procedures, improvement in fidelity based on the educational goals for the particular skill.
