At a time when virtual reality applications are beginning to grow vigorously, many market views think that virtual reality can be used as a job training application for enterprise employees, so content such as "Job Simulator" has been launched one after another. In order to test whether the work training effect can be achieved through virtual reality, the Google Daydream lab team conducted an actual test to compare the training results through virtual reality or by watching YouTube films.

According to the actual test results of the Google Daydream lab team, it is shown that the overall result of training how to brew a cup of coffee through virtual reality is twice as good as learning by watching a movie. Although there are still some problems such as taste gap no matter which training method is used, it is easier for trainees to remember the overall operation process by simulating the actual operation process in virtual reality, such as filling coffee powder from a bean grinder. And brew Italian espresso through the equipment, and then add milk or dilute it into American coffee according to customer needs.

On the other hand, trainees who watch the film to learn the coffee brewing process may be more likely to have problems such as operational errors and reversal of order, and may not even be able to cope with the actual pace of ordering in the restaurant. Therefore, from the actual results, although there is no guarantee that trainees can make coffee with excellent taste through virtual reality training, there are relatively fewer errors in the process of operation. Google also confirms that the virtual reality training model is indeed useful.

However, many practical problems have been exposed in this experiment.

First of all, coffee is a bad choice. The physical sensation of grinding beans and pressing powder obviously cannot be simulated by a simple vibration buzzing sound. In addition, no matter how many times the volunteers were warned not to touch the virtual steam nozzles, they were always too close to the nozzles in the real world, so the researchers needed to prepare hands to pull their hands back at any time. This shows that for some skills, virtual reality training is not yet mature. Until the tracking performance of gloves is improved and tactile feedback becomes mainstream, VR training will still have restrictions on input, such as being able to operate only through the controller or using buttons. If there is too much distance between the digital analog object and the real object, it may not be of much help to the skill learning.

At the same time, Google has found that people don't follow instructions. This can be seen in all prototypes produced by Daydream Labs, which is a particularly big problem for trainers. Instructions located on the controller? People put their hands on both sides; write on the backboard? Their attention is focused on what is in front of them; use narration? They don't have the patience at all; Google even adds a "prompt" button, but people think it's cheating, and in any case, they always forget after a step or two. So Google finally combines all of the above methods and adds tags to the scene. Large green arrows indicate what the user should do. But Google says it has not solved the problem and that more needs to be done to integrate instructions effectively.

Therefore, Google also shows that virtual reality training may not completely replace the traditional training mode, but mainly as an option among many training contents, such as simulating the actual operation situation through virtual reality, so that trainees can learn more closely to the real situation. at the same time, it can also ensure certain risks for training units and reduce training costs. Previously, NASA and other units have used virtual reality equipment to allow astronauts to simulate the possible situation of the space station, but they do not need to spend a lot of money to build simulated space gravity environment and operation training equipment, and use computers and virtual reality to simulate the operation of related equipment, so that astronauts know and get used to all kinds of situations.

At present, more and more people are engaged in work training, psychotherapy, or situation simulation before major surgery through virtual reality, and there are even many application models that enable people to work together in virtual reality situations at the same time, or even to interact remotely, and so on. Many markets think that virtual reality will bring many application opportunities.
