One of the essential requirements of a realistic surgical simulator is to reproduce haptic sensations due to the interactions in the virtual environment. However, the interaction need to be performed in real-time, since a delay between the user action and the system reaction reduces the immersion sensation. In this paper, a prototype of a coronary stent implant simulator is present; this system...

Computer-based surgical simulation promises to provide a broader scope of clinical training through the introduction of anatomic variation, simulation of untoward events, and collection of performance data. We present a hapticallyenabled surgical simulator for the most common techniques in diagnostic and operative hysteroscopycervical dilation, endometrial resection and ablation, and lesion exc...

Objective. The objective of this review was to compare traditional intravenous (IV) insertion instructional methods with the use of haptic IV simulators. Design. An integrative research design was used to analyze the current literature. Data Sources. A search was conducted using key words intravenous (IV) insertion or cannulation or venipuncture and simulation from 2000 to 2015 in the English l...

A collaborative hapto-visual virtual system consisting of two similar networked stations allowing two users to collaborate within a learning environment is designed and implemented. This system uses a server–client configuration for haptic rendering. The haptic component runs a real-time operating system and consequently allows for better response. A second component used for haptic collaborati...

The emergence of force feedback haptic devices that can remotely interact with virtual environments presents a number of challenges to the underlying networks that have to support their interactions. One important issue concerns the characterisation of haptic traffic, particularly whenever multiple users remotely interact over a network such as the Internet. Previous research has characterised ...

INTRODUCTION Laparoscopic virtual reality simulators are becoming a ubiquitous tool in resident training and assessment. These devices provide the operator with various levels of realism, including haptic (or force) feedback. However, this feature adds significantly to the cost of the devices, and limited data exist assessing the value of haptics in skill acquisition and development. Utilizing ...

This paper presents a new model which computes the deformation and the feedback force of high-resolution biomedical volumetric objects consisting of hundreds of thousands of volume elements. The main difficulty in the simulation of these high-resolution volumetric objects is to compute and generate stable feedback force from the objects within a haptic update time (1msec). In our model, springs...
