Virtual Realities - empennagevas ExampleNASAs mandate is to address cardinal elements before introducing a new training modality curve training costs, improve safety and improve spaceman performance. Any new technique needs to turn up superiority in at least one of these parameters. It is important to note that there is a evidential S-curve effect in adopting any new methodology lots of effort going in, accordingly prodigious payback as the new methodology is adopted and demonstrates greater productivity.One bathroom 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. in that location is therefore a substantial record of learning times on specific tasks, which can then(prenominal) be correlated using real spac ewalk experience. With over 30 astronauts who 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 effectiveness, 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 attain sheet for NBS would look as followsOn the groundIn spaceCost per trained astronaut$/astronautN/ATasks performed in effect% of tasks performed effectively% of tasks performed effectivelyTasks performed safelySubjective rating (1-10)Subjective rating (1-10)By comparing on-the-ground NBS oodles with in-space actual scores, 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 tasks for eventual EVA tasks can be evaluated and scored, as follows, one score sheet each for effectiveness and safetyEffectiveness Score Sheet (example) installSpace% achievedWeighting 1-10Activity 195% 85%85/95= 89%9Activity 299%98%98/99=99%6. . .By weightiness 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. produce a score which normalizes NBS results for use when looking at IVR, and 3. Establish which areas have the greatest potential for improvement, thereby increase overall scores.The above scoring approach works for both the safety
