Boxes filled by boxes. Virtual and reality.

Real and virtual world

Suppose, by contacting the robot sent to the accidental area, he will be asked to make a continuation of the next step. Here are a couple of problems. The medium of communication between the robot and its man driver is very unreliable, some data will be lost, some will be distorted. Let's say that the robot is trying to repair some of the rooms in a nuclear center facing the Meltdown. Because of the accidents, there is no way to know about the current condition of the room that the robot can be taught beforehand. When the robot is moving slowly, he will collect information about his surroundings and send his master to the master. Explain the data of the driver and understand the surroundings of the robot and send him the command to the next step. It may be right, go to the left, rotate the screw, and do some common commands like this.

The main work here is to solve the difficult issues, such as the unreliability of the information, instantly large amounts of data analysis. But the man who manages this robot based on this information, how well do you understand the situation from the simplified analysis of the computer? If the driver himself could walk on the accident, but he had no physical or mental harm, then he could repair or retrieve his knowledge with better knowledge about the situation.

Of course, the solution is to make a magic suit, no one can harm anyone. What can computer science do to create magic suits in the hands of magicians? Since we can not go to the nuclear reactor, we can think of bringing the nuclear reactor to our laboratory in such a way. I am not so ambitious, so do some planning near the soil. We have a robot's data regarding its situation. If all of them are added to a 3D virtual model, then the virtual model can be filled in a box, but only then the accident will come to us. The rest of the virtual world is going back to the people, and working in the real world through a robot avatar.

In the virtual world there is a small system of virtual travel arrangements in the virtual world. But Virginia Tech took the matter to another level. We have three stories tall, wide and long a huge cube, and it is called "cubes". One advantage of Cube's magnitude is that it is possible to put a roughly realistic 3D dimensional model into this box. Suppose we want to build a dimensional model of a medium-sized gymnasium or somebody's living room and fill it in that box; It is possible to adjust to the real scale. However, it will not be possible to build the field of Tepantara and press the horse into it.

Another advantage is that it is possible to move around the cube and walk in the same virtual world as well. In order to make the case possible, the cubic must have the ability to track the person or the position of the person walking in it. Since the size of the cube is too much, there are a number of tools needed to track moving person / object moving in.

There is a total of 24 infrared cameras installed at equal distance around half the height of the cube, which can simultaneously throw infrared light inside the room, and if the light comes back after being reflected in any object, it can calculate the position of the reflective object with collective knowledge. Note that for the three-dimensional positioning, you must know at least three cameras distance from the same reflector.

Since there is no shortage of cameras, knowing about the position of each reflector is not a problem. Suppose two reflectors move at the same time, and at one point they came very close to each other, and at the moment they started moving away again. The Cube will not understand it anymore. Let's think about twenty or thirty people are moving at the same time. Cubic poorly agitated in a rage, despite being turned into a point in the BigCrunch, he can not be blamed. So, the way to survive?

Another thing is that everyone can not completely reflect infrared. For this reason, the person or object that is tracked, is given a silver-colored infrared reflective spherical sensor. So far as I was saying about the problem, it is necessary for every person / object to be recognized uniquely even after the crossover, an intelligent solution. Note that there is no variation in reflected energy from the sensor. Let me cube the track. That's why I took a hallmat on my head. The 4/5 sensor on the helmet is placed in a format.

Now I will give the cube some time for calibration. Cube will remember this 4/5 sensor's 3D layout as a goal to track. The next person's headpiece will be remembered as the second target by putting more 4/5 sensors in a different three-dimensional format. In this way, different things will be remembered for each item. Later, when all targets will start moving together, after crossover it will be possible to identify each target separately from their helmets sensor's unique three-dimensional layout. The whole process is simplified and shown in the picture below.

tracking

The entrance door to the virtual world
will look like a box-box on the inside of the cube, and it will not be entered into the virtual world. Different technologies can be used for that work. In most cases the users of Cube use a monocular rift head mounted display. Firstly, by completing a three-dimensional model in the Unity game engine, it is consistent with the three-dimensional level of the cube (scale matching). After that the model was added to the cube tracking system. The easiest way to move in a 3D model is to shift the position of the model's camera. For this speed from the First Person Perspective, the model camera has to match the user's head. Playing a first person shooting game, anyone who understands this thing easily.

The problem is that, if the feet of the cubes fall into the zero point of the eye, then the user will be able to see himself at the starting point of a three-dimensional model. After that, when he moved somewhere else, the cube tracking system will tell the Unity game engine by calculating its new location. The unit will then render the scenes of the three-dimensional camera in that new position and render the surrounding scenes again. And in this way, realistic modeling and the correct amount of calibration walks through the cube, in reality, there is a realistic feeling of walking around the virtual world.

Way to reach

the virtual world is a garden or park, it would be enough to just walk beranoi. But if we are not satisfied with walking just like asteroids or want to change the virtual world's material or want to change it, then additional technology will be needed. A great way is the lipmotion handraver. If you put a hand in front of a small device of this liposuction, then he can recognize the different strains of the hand. If transcription information is sent to the unit, it can be possible to compare the different handpoints in the realm of the real world with programming. For example, when someone guides the index finger to an object, it can be translated into the object.

Shaheed Qader Molla Bhai, if you want to show V sign again from heaven, then you can see that the world's people will send it to you by sending the information through Vibrant Leap in front of Leap Motion. Even if he showed the mediator in the happiness that the blogger and free-spirited converters had been converted into the mass killing grounds to seek his execution, then he could understand the Leap Motion.

Do you remember the scene of the Minority Report, where Tom Cruise was analyzing the horizons in Oracle's vision? Leap Motion has turned this thing into a matter of real fact. However, LipMotion is not the only way, any tracking system can be used for this purpose with enough programming.

Some cubes of cube can be used for
various purposes, in entertainment or serious research. But like the previous day's shared computer, it's time to get bigger Huma. It is available for several hours after several hours. So far, the serials that have been used in this project have been visualized in them, visualizing large-scale organic molecules, visualizing cyclone and analyzing. There is also data visualization and cropping analysis. I'm doing a class project with the Future House, where each one is working on each part. If you look at an object like a terminator in one part, arrange to see all the information related to it in the virtual world.

The last word

though blogging is very bad things, but nothing like this blog do not eat at all knock. This is not a science blog, but a completely technical blog. A renowned technologist from the country's top triangle triangle. Besides, "Ten ways in which the wife will keep her husband happy" etc. The information provided by us to the public or the Bamboo Kella Group, which is the most accurate information about any issue in the country, is fabricated and operated by the renowned technicians. So proven technology is good writing.
