Virtual Realities - Essay ExampleNASAs mandate is to address three elements before introducing a new training modality tailor training costs, improve safety and improve cosmonaut performance. Any new technique needs to demonstrate superiority in at least one(a) of these parameters. It is important to note that there is a momentous S-curve effect in adopting any new methodology lots of effort going in, so significant payback as the new methodology is adopted and demonstrates greater productivity.One can look at NBS as a perfected technology, one in which a lot more effort will not improve the methodology very much. If, on the other hand, IVR can be shown to be superior at present, the S-Curve effect dictates a greater improvement in the future.NBS has been established since the 1960s to help train astronauts on EVA. There is therefore a substantial record of breeding times on specific tasks, which can then be correlated using real spacewalk experience. With over 30 astronauts wh o have gone through the NBS training, then the actual EVA experience, we therefore have a database to establish four elementsTwo elements cost to train and potence, can be measured on NBS in a fairly straightforward way. Safety, however, can only be subjectively addressed. This is because there have been no significant safety problems that have led to the loss of an astronaut or a hazard that has stopped an entire mission. In this case, a stimulate sheet for NBS would look as followsOn the groundIn spaceCost per proficient astronaut$/astronautN/ATasks performed effectively% of tasks performed effectively% of tasks performed effectivelyTasks performed safelySubjective rating (1-10)Subjective rating (1-10)By comparing on-the-ground NBS gain ground with in-space actual places, we can therefore normalize the NBS effectiveness and safety results to correlate them with in-space EVA results.Each of the tasks judged to be important can be thus scored, and a complete score for all NBS t asks for eventual EVA tasks can be evaluated and scored, as follows, one score sheet each for effectiveness and safetyEffectiveness Score Sheet (example) plantSpace% achievedWeighting 1-10Activity 195% 85%85/95= 89%9Activity 299%98%98/99=99%6. . .By weighting each task in regards to its importance to the mission, NASA can come up with an overall weighted score which allows for establishing the effectiveness of the training, and how much additional improvement can be made per task, and in overall EVA tasks performed. The three ways to use this are1. Establish the effectiveness of training using NBS on the eventual results.2. Create a score which normalizes NBS results for use when looking at IVR, and 3. Establish which areas have the greatest potential for improvement, thereby change magnitude overall scores.The above scoring approach works for both the safety
