-After the surgery is done, save the recording. The recording may be upload to the university server or the cloud.
-The video then will be downloaded and analyse by senior surgeons and fellow trainees to provide feedback of your operation
Reliability of the IT system will be concern if the details of the graphic are low. This is because student will miss the minute detail of human body if some of the details are not available. Besides, low graphic means that the output will be more pixelated, which may cause nausea especially in VR. Besides that, the input lag present in the system itself may make movements hard to perform. This is because of the appliances use itself, such as the controller which was built using wire that transfers data slower which is cheaper to be use.
A positive impact of the IT system to the student is that it allows them to get experience without having to suffer the consequences and panic. As the system take place in a virtual world, the students are prevented from hurting living patients. As a result, the students can do the surgery again and again seamlessly. Additionally this will help the student to do their practical without the cost and time of equipment that must be sanitized and bought countless time.
On the other hand, a negative impact such as input lag in the system will affect the student greatly. Having a delay of hundreds milisecond when inputting a hand movement command may turn off the student and frustated them. This may prevent the student from doing the surgery with efficiency as surgeon are doctors who need to react quickly.This may be the biggest drawback of the system to them. Besides, students will also treated this simulation like a game. This will make them feels like this thing is not that important and will treated it lightly, giving them a false sense of security. This is a big problem when they are told to perform surgery on a live person as they may make fatal mistake which will cost the patient life.
A positive impact for the senior doctor is that they can review the video countless time to observe more carefully with minute detail on the surgery perform. As a result, the senior doctor can help to improvise the students technique and showcase the wrongdoing by replaying back the video. Besides that, being able to download the video help the senior doctor to review the video anywhere and anytime. This help to cater to the senior’s doctor busy work schedule and help them be relief from tight work schedule.
On the other hand, due to the new nature of VR system, the doctor need to learn the usage of it. They need to now how to initiate the programme and how to perform it. This may cause a lot of trouble especially for the elderly doctor who has a hard time keeping up with new technology. Besides, the constraint of time will hinder their learning about this new system. Next, reviewing video at home may cause them to work more that the time they were paid for. This will cause a lot of stress and sleep loss, thus will affect their brain process during surgery.
Weighing up, one may conclude that the positive and negative impacts for the students and senior doctors are interconnected. For the student, the reliability and false security outweigh the saving of cost and time together with the ability to perform surgery many times. For the senior doctor, the stress gained by using VR system also outweigh the ability to replay a video to spot minute mistake. In conclusion, the system does have positive implications but the number of people affected negatively is greater than those affected positively to the point where those negative point outweigh the benefit.
A major problem experienced by the stakeholder is the reliability of the IT system. To combat this, the developer of the IT system should implemented a gigabit ethernet/better Wi-Fi card if the VR system is virtually based on the cloud, the reason is so that more bandwidth can be used by the vr system. This enable data from the input and to the output on the cloud system to be faster and thus eliminated the packet loss or high ping. This will enable smoother simulation and also high quality image.
The positives of this solution is that it greatly increases the reliability of the the system by providing more accurate movement and graphic. This will enhance the user experience while being easy to implement. By having a better hardware for the network part of a system, this may attract the attention of trainee student as the frustrating feeling of delay and slow reaction time are eliminated.
On the other hand, such implementation of networking hardware may increase the cost of the system as more advance and modern network card and ethernet require more money to buy. University usually has a lot of other things to pay such as the bill, the scholar ship and other more important equipment. University with low finance which is usually at third world countries such as Africa may experience problem in buying this vr equipment with the higher cost.
In conclusion, this solution may indeed help to alleviate the reliability issues arising from the system. Its positives outweigh its negatives as the money spent on a better networking hardware will help to produce more surgeon which are in dire need in South Africa and may allow the system to be more widely implemented. As such, the solution is effective and viable, although it does demand additional cost which is justified by the achievement of the intended purpose of the system while ensuring the reliability of the system.
