“…Ce type d'actes requiert une bonne coordination oeil-main, des capacités spatiales tridimensionnelles, et des compétences de perception haptique. Plusieurs simulateurs virtuels pour le geste d'insertion d'aiguille ont été proposés [33,34,29,35]. Le lecteur peut se référer à deux revues de la littérature récentes sur le sujet [36,37].…”

La réalité virtuelle est une technologie prometteuse pour former les professionnels de santé dans un environnement de simulation sécurisé. Dans ce travail, nous présentons la conception et l'évaluation d'un simulateur immersif pour la formation de l'anesthésie locorégionale échoguidée. Dix-huit anesthésistes ont participé à la validation de l'aspect et du contenu du premier prototype du système. Les réponses à sept des onze questions sur la validité de l'aspect étaient positives. La problématique soulevée concerne la fidélité du rendu haptique de l'aiguille, suggérant l'utilisation d'un bras haptique à six degrés de liberté dans les futurs prototypes. Les réponses aux six questions sur la validité du contenu étaient positives. Les participants trouvent que le simulateur est un outil de formation prometteur particulièrement adapté pour développer les compétences de coordination oeil-main. Ces résultats confortent nos choix de conception et suggèrent des améliorations pour notre simulateur avant sa validation comme outil de formation.* Auteur correspondant is a promising training tool particularly suited for developing hand-eye coordination skills. These results support our design choices and suggest improvements for our simulator before its validation as a training tool.

“…Indeed, force feedback has been recognized as important when performing motor skills, particularly for surgical skills [11,14,15,38], but also for industrial maintenance tasks [19,29]. These interactions are particularly interesting for tool-based motor tasks, since a shape-alike tool can be coupled with the device to achieve a better representation and reproduce the same interaction as expected in real procedures [20,38]. This suggests that the use of haptic devices is important to support tool-based interactions in VR simulators.…”

Mastering motor skills requires performing the task unconsciously with great speed and accuracy. This is acquired slowly through practice over time. Nonetheless, in domains such as surgery, the training of these skills in the field introduces safety, ethical and economic issues. In this context, immersive VR technologies offer the possibility to recreate real-world situations and allow the trainees to improve their skills in a safe and controlled environment. However, the design of such systems raises new research questions, such as how to represent the user in the virtual environment, and whether this representation can influence motor skills automaticity.In this work, we focus on how the user's hand representation can impact the training of tool-based motor skills in immersive VR. To investigate this question, we have created a VR simulator for training a tool-based pick and place task, and conducted a user study to evaluate how the user's hand visualization can influence participants' learning performance after a two-week training period. For that purpose, two groups of participants were trained in the VR simulator under one of the two experimental conditions: the presence and the absence of their virtual hands' representation, while a control group received no training. The results of the study show that training on the VR simulator improves the participants' motor task performance when compared with the control group. On the other hand, no difference was observed between the two training groups. This suggests that the user's hand visualization does not always impact tool-based motor tasks training in immersive VR simulators. Indeed, for short-term motor training there was no difference in performance between having a partial embodiment of the user's hands and only the tools representation.

“…However, no visual feedback experience was included in this system. Other simulators have also been developed for training different needle insertion procedures (Torres et al, 2012;Sutherland et al, 2013;Corrêa et al, 2014;Henshall et al, 2015). The reader can refer to this recent literature review on needle insertion simulators (Corrêa et al, 2018).…”

“…Users were able to visualize different models through different points of view using the keyboard. Henshall et al (2015) VR prototype for kidney biopsy allows visualizing anatomical models of the spine, liver and kidneys in order to perform a needle insertion. For this prototype, the user's head position was tracked to provide a first-person perspective of the operational field.…”

Recently, virtual reality (VR) technologies started gaining momentum in surgical simulation-based training by allowing clinicians to practice their skills before performing real procedures. The design of such simulators is usually focused on the primary operative tasks to be taught, but little attention is paid to secondary tasks that the user needs to perform, such as changing his/her point of view when manipulating the surgical instruments. More particularly, it is not clear how to design appropriate interaction techniques for those tasks, and how the fidelity of these interactions can impact the user's performance on such systems. In this paper, we compare two viewpoint changing techniques having two different levels of interaction fidelity during needle insertion in a semi-immersive VR (SIVR) biopsy trainer. These techniques were designed based on observing clinicians performing actual biopsy procedures. The first technique is based on tracking the user's head position (high interaction fidelity), while the second technique is touch-based with the user utilizing his/her non-dominant hand fingers to manipulate the point of view on a touch screen (moderate interaction fidelity). A user study was carried out to investigate the impact of the interaction fidelity of the viewpoint changing task (secondary task) on the user's performance during the needle insertion task (main task).
