Compare to traditional training, virtual reality simulation-based training[Reznek 2002,Seymour 2002,Freeman 2001,Gallagher 2005] have proven to have advantages in term of of convenience and repeat-ability and is a valid approach for improving an operator familiarity with procedures that requires hands on experiences.
Decision making[Vannaprathip 2016] has already proven itself to be a viable training that fit perfectly with the form and the interaction allowed within our system. Using serious game approaches of in-game narrative style combine with  visual and audio cue we can create an interactive tool that teach emergency and stressful situation handling very effectively and using gamification technique,  we hope to maximize engagement and memory retention Tsui 2014,Chittaro 2015.

In order to convey the emergency and possible panic inducing situation which can happen during a medical operation and not normally taught with traditional training method, we use VR for the training to achieve highest immersion. 

Using VR related in emergency training has been done before for example Freeman 2001 but most of VR based studies are training of procedures under relatively normal situation. The trainee normally knows what to expect to do in the training. Our study want to focus on how an operator would and should handle the unexpected emergency situation that can occurs during the surgery procedure that require precision, in which the mishandling of the sudden emergence could be costly to the patience.

we select cardboard for the easy accessibility, mass adaptation and portability. The decision is based from the same as how a game designer/marketing would choose the platform.

Following Vannaprathip 2016's Desitra, We choose endodontics surgery decision making simulation as the base for our application due to the compactness of the surgery that at the same time also has multiple possibility of emergency situation that can happen during the surgery. 

Taking lesson from Pearson 2003's study of how voice recognition can be used to effectively created a responsive, direct voice input simulation, we use google voice recognition library in our simulation to create a responsive assistance that the operator can ask for equipment during the operation.

Our recreation of the operating room and the ambient are not based on the as-realistic-as possible approach but as Bowman 2007 has found, focusing more on convincing the user of being in the computer generated world is a better approach.
