This paper presents an investigation towards the simulation requirements for virtual regional
anaesthesia training. To this end we have developed a prototype human-computer interface
designed to facilitate Virtual Reality (VR) augmenting educational tactics for regional anaesthesia
training. The proposed interface system, aims to compliment nerve blocking techniques methods.
The system is designed to operate in real-time 3D environment presenting anatomical information
and enabling the user to explore the spatial relation of different human parts without any physical
constrains. Furthermore the proposed system aims to assist the trainee anaesthetists so as to build a
mental, three-dimensional map of the anatomical elements and their depictive relationship to the
Ultra-Sound imaging which is used for navigation of the anaesthetic needle. Opting for a
sophisticated approach of interaction, the interface elements are based on simplified visual
representation of real objects, and can be operated through haptic devices and surround auditory
cues. This paper discusses the challenges involved in the HCI design, introduces the visual
components of the interface and presents a tentative plan of future work which involves the
development of realistic haptic feedback and various regional anaesthesia training scenarios.
This paper presents an initial study exploring and evaluating a novel, accessible and user-centred interface developed for a VR Medical training environment. In particular, the proposed system facilitates a detailed 3D information exchange, with the aim of improving the user's internal 3D understanding and visualisation of complex anatomical inter-relationships. In order to evaluate the effectiveness of the proposed VR teaching method we developed a female 3D model under the guidance of Consultant Breast surgeons with particular emphasis given on the axilla section. In turn we commenced a comparative study between PBL tutorials augmented with VR and the contemporary teaching techniques involving twelve participants. Overall the paper outlines the development process of the proposed VR Medical Training environment, discusses the results from the comparative study, and offers suggestions for further research and a tentative plan for future work.
