In this study, a force reflection control structure is developed for the surgery training haptic system. In the surgery training haptic system, the surgical operation is cooperatively performed by a trainer and a trainee. The participation of each surgeon in the operation is established through their own haptic consoles. Although the operation is primarily performed by the trainee, the trainer ...
Background & Aim: Several methods have been reported for refixation of dislocated intraocular lenses (IOLs). However, these methods are associated with some disadvantages including vitreous prolaps, vitreous traction, ocular collapse, intraocular hemorrhage, high astigmatism, and the need for complex intraocular maneuvers. The aim of this study was to evaluate the results of transscleral fi...
objective: to investigate the correlation between lower and higher order sensory functions and manual dexterity as well as to identify the sensory measures that could predict manual dexterity in patients with idiopathic parkinson’s disease (pd). materials and methods: in this cross-sectional study, 55 patients with idiopathic pd by mean age of 59.85 ± 11.89 years, and mean hoehn and yahr stage ...

New 3D video representations enable new modalities of interaction, such as haptic interaction, with 2D and 3D video for truly immersive media applications. Haptic interaction with video includes haptic structure and haptic motion for new immersive experiences. It is possible to compute haptic structure signals from 3D scene geometry or depth information. This paper introduces the concept of hap...
Since haptic rendering requires at least 1 kHz device control latency to obtain high haptic fidelity, haptic rendering process must be separated from others in realtime virtual reality system with haptic/force feedback. Feature-Based Haptic Rendering gives process architecture for load balancing. Haptic rendering is done based on features using feature library. Feature is local haptic character...
All figures are expected to be printed in one-column 2 ABSTRACT This paper presents a survey of the main results obtained in the field of " pseudo-haptic feedback " : a technique meant to simulate haptic sensations in virtual environments using visual feedback and properties of human visuo-haptic perception. Pseudo-haptic feedback uses vision to distort haptic perception and verges on haptic il...
This paper presents a survey on haptic technology, virtual reality, and artificial intelligence applications in medical training during the COVID-19 pandemic. Over the last few decades, there has been a great deal of interest in using new technologies to establish capable approaches for medical training purposes. These methods are intended to minimize surgerychr('39')s adverse effects, mostly w...
Visuo-haptic biases are observed when bringing your unseen hand to a visual target. The biases are different between, but consistent within participants. We investigated the usefulness of adjusting haptic guidance to these user-specific biases in aligning haptic and visual perception. By adjusting haptic guidance according to the biases, we aimed to reduce the conflict between the modalities. W...
This study investigated the haptic 'dissection' of a digital model of the hand and wrist in anatomy education at both undergraduate (UG) and postgraduate (PG) levels. The study ran over five successive years and was split into three discreet phases. Phase one compared the results of PG students across control, non-haptic and haptic groups. Phase two compared the results of UG students between c...
