In training assembly workers in a factory, there are often barriers such as cost and lost productivity due to shutdown. The use of virtual reality (VR) training has the potential to reduce these costs. This research compares virtual bimanual haptic training versus traditional physical training and the effectiveness for learning transfer. In a mixed experimental design, participants were assigned to either virtual or physical training and trained by assembling a wooden burr puzzle as many times as possible during a twenty minute time period.After training, participants were tested using the physical puzzle and were retested again after two weeks. All participants were trained using brightly colored puzzle pieces. To examine the effect of color, testing involved the assembly of colored physical parts and natural wood colored physical pieces. Spatial ability as measured using a mental rotation test, was shown to correlate with the number of assemblies they were able to complete in the training. While physical training outperformed virtual training, after two weeks the virtually trained participants actually improved their test assembly times. The results suggest that the color of the puzzle pieces helped the virtually trained participants in remembering the assembly process.

“…When comparing models as assessment tools for TQ, however, the MATT (KGS Trauma Fx) appeared to be a more difficult testing model than the goat with difficulties in transfer effectiveness. 34,35 While skills learned on STM seemed to translate to successful completion on LT, skills learned on LT did not translate to successful completion on STM. Anecdotally, the experienced physicians and Special Forces medics on the study team felt that supratherapeutic forces often seemed necessary to provide effective arterial compression in the MATT STM due to the lack of tissue fidelity.…”

“…This lack of anatomic fidelity could potentially lead to negative training transfer with subjects subsequently deciding to perform chest tube placement too low to be safe. 34,41 Furthermore, the amount and type of force required to puncture through the chest wall in our simulator could vary depending on how the tissue layers are assembled. This lack of tissue/functional fidelity, which does not allow the learners to understand the correct feel of the tissue planes, could potentially negatively impact future performance.…”

“…33 While the aim of this study was not to formally evaluate transfer effectiveness ratios, our results suggest that the complexity of procedure may be related to the amount of time and practice necessary to develop competence, but does not necessarily predict whether transfer of training between models will be successful. [34][35][36] When examining the impact of LT versus STM as the training modality (STM-LT vs. LT-LT), no difference was found in six of seven procedures studied when examining either outcome measure (CF or PS). Tube thoracostomy demonstrated a significant difference, with more CFs in the STM-trained group (Table 8).…”

Simulator training provides the opportunity to acquire and practise technical skills in a safe, controlled and reproducible environment without the risk of harming patients. Although there is no evidence to prove that patient outcomes are worse if trainees undertake interventional procedures, there is an inevitable concern that procedures may not be as safe or successful if undertaken by doctors in training. 1,2 Experiential training in the workplace exposes patients to the theoretical risks of the learning curve of trainees, especially in the radial era. 3 Further, as catheter laboratory (cath lab) scheduling time is precious, having trainees undertaking procedures that inevitably take longer can be difficult to justify when the focus is on lab efficiency. Simulator training has the potential to offer focussed training opportunities that allow both the time and space to develop interventional skills. 4 These skills can then be analysed and critiqued without any risk of patient harm or impact on the cath lab schedule.Enthusiasm for simulation training has increased dramatically over recent years because advances in technology have allowed the delivery of authentic simulated training opportunities.Despite a broad body of evidence supporting the use of simulation in medicine, there are still some concerns when this evidence is extrapolated to less studied specialties. 5 Simulation training enhances learning, especially when used alongside traditional, apprentice models of training, and it is now increasingly recognised in cardiology and interventional training programs. 6,7 In interventional cardiology the evidence and experience of simulation continues to grow, although presently there are no studies that have documented a positive effect on patient outcomes.As mentioned, many healthcare settings have restricted the weekly working hours for doctors in training due to an increasing demand on cath lab schedules. 8,9 Institutions are becoming risk averse and often limit training opportunities through fear that patient outcomes might be lowered when procedures are undertaken by doctors in training. 1These two factors reduce exposure to practical procedures thus weakening the skills and experience of future specialists. Experience is an essential component of becoming an independent operator.Solutions are therefore required to enhance and increase training opportunities and simulation is one of the most useful practical options. Supervised simulated training experiences away from the bedside in a controlled, authentic environment will allow trainees to explore and develop techniques and consolidate their learning without exposing patients to risk, as has been seen in other medical specialties. The Role of Simulation in Other Medical SpecialtiesSimulation is a long established form of medical training. 10 The early cardio-pulmonary resuscitation dolls are a simple but effective way of delivering the core elements of resuscitation training by providing a safe environment to practise and rehearse tasks, algorithms and al...
