These novel things like AR experimental equipment have really become very popular in recent years! Many schools and laboratories have also bought a lot of them, but many people are just as confused as me when they get them. They don’t know where to start fiddling with them. The instructions are dizzy or they can’t figure out how to operate them—not to mention those advanced functions, which are as desperate as reading the heavenly books! Today I will tell you about some of the experiences I have learned from touching the elephant by blind people during this period, as well as the pits I have stepped on, and the tears I have shed. I hope it can help those friends who love and hate this fresh thing like me, so that everyone can use it less effort and less worry!
AR experimental equipment, simply put, is to use the augmented reality technology that sounds extremely advanced, you know? It is the kind of technology that can mix virtual things with reality, and cleverly combines the bottles, jars and instruments used in experiments – a set of novel operating tools created! What can it do? Tsk, there are too many! For example, it can simulate a particularly dangerous chemical reaction process so that you can see clearly without worrying about being blown up; it can also lead you to disassemble a 3D three-dimensional model. What is the most important thing that is more than 100 times more intuitive than looking at a floor plan? It can help us beginners to familiarize themselves with various complex and high-end experimental processes, so we don’t have to worry about breaking expensive real guys because of their clumsy hands. It’s really too considerate and powerful!
1. Hardware preparation and connection :
Let’s talk about this hardware first. The first step to get the device is to think about the hardware! Generally speaking, you will have an AR headset that looks weird like glasses, and there may be several sensors used to capture your hand movements… Maybe there is a small base station for position tracking in the corner – in short, parts are indispensable. If there is any missing, you have to find the seller as soon as possible and don't guess it yourself!
Then there is the connection, and the wire and interface can make people dizzy! Should I connect my headset and computer? The sensor must also be paired with the host? It is important to note here that the data cable interface of different brands of equipment may look completely different. Don’t force it to insert it. Use some force to see if it can’t be inserted, so stop and find out if it’s right. If the interface is crooked, it’s too late to cry! There are also some considerations in the order of booting. Generally, you turn on the computer first and then start the display after the computer is slowly started. Otherwise, sometimes it will not be connected, which is particularly anxious and annoying!
Also, that positioning is to ensure that what you see with your eyes is accurate, which is particularly important! The room is too bright, not too dark. Some equipment also chooses a venue. There cannot be too strong reflective things on the ground, and there cannot be too many messy debris that block infrared signals. Otherwise, the picture will shake, float, and it will be dazzling. How can you do an experiment?
2. Be patient when installing and calibrating software :
Once the hardware is ready, it’s the software’s turn, and this thing is not a fuel-efficient lamp! Generally, the official website will provide the dedicated AR experimental software. You must see clearly that version and strictly correspond to the hardware model you bought. If the version is incorrect, it will be useless if it is downloaded. Maybe there will be security risks. Don’t just save trouble and use it!
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" Some options, such as "install driver" and "allow access to camera/microphone", must be checked, otherwise the software will not work normally, and you won't be able to do it at that time!
After the installation is completed, the most important step is to calibrate! It is equivalent to "tuning your eyes" for the device and performing "space (perception) calibration" on yourself. It literally means letting the device know where you are and where you look. If this step is not done well, the virtual experiment (instrument) you see may float in the air and be crooked, or if you gesture with your hand, you will not be able to catch the virtual operating rod, which can make people anxious and angry! Follow the prompts that the robot on the screen that you don’t understand, slowly turn your head, stretch out your hand, aim at those annoying calibration points, try a few more times, don’t be afraid of trouble, it doesn’t matter if you are slow at the beginning, then it’s soon!
3. Basic operations and common functions exploration :
Only when the headset is comfortable can you do a good job of experimenting! Keep the elasticity well, don't always fall down like a slide – don't be too tight, so that your head hurts and you can't stand it and want to give up if you can't wear it for a while; if the lenses are dirty, you have to wipe it. Use that special soft cloth to gently rub it like a kitten. Don't rub it randomly with your greasy sleeves or cardboard shells. If you scratch the lenses, you will be finished!
Then how do you interact with that invisible and intangible virtual object? There are generally two ways, either use your hand to gesture in the air like a martial arts gesture… or use a strange-shaped "control stick" – this one needs to be practiced more against the device and be familiar with the best angle it recognizes… Do it several times in slow motion to find the feeling, for example, "grab" usually turns your wrist slightly and stays for half a second, not just like a kitten fishing.
There are various prefabricated virtual experiment templates in the APP, such as "basic physical and mechanical experiments", which are all practical, or if you accidentally break a virtual instrument and can reset it in one second, you don't have to worry about whether to compensate. It's simply too convenient. Provide global procurement services for weak current intelligent products! You can first start with which simplest one, follow the virtual instructor who speaks in a mechanical voice step by step. If the operation is wrong, it will usually be called. Sometimes the virtual teacher will use its emotional tone to remind you what was wrong. If you are much more patient than the real teacher, you will not scold people. After you finish it, you can still play back the steps you messed up just now. Think about why you were wrong. You will be able to get it right next time and you will know what to do! Many times, it is the truth to find experience in failure over and over again! There are many professional functions and settings. If you are not professional, it is recommended not to set parameters casually!
Do you have any friends like me? Are you worried that the equipment suddenly ran out of power and the machine stopped working? This big problem! So once you get the charger, you have to find a fixed place to put it in. Develop the good habit of charging it casually after using it. Don’t wait until the light starts to flash red light to warn you before thinking about charging. At that time, you just happened to take the key steps. Suddenly, the crash or shutdown will make people hate it! There is also the small screen inside the headset. Don’t disassemble it and wipe it yourself. If there is dust, just find the small glue stick that sticks to dust and stick it gently, otherwise it will get worse and worse or even tear the line off. Then you should be scolded by the boss or pay for repairing it yourself! If you think an operation is particularly difficult to understand, you must actively ask questions and ask those knowledgeable friends or customer service to find out the ins and outs!
I personally think that although this AR experimental device was particularly complicated and headache when I first came into contact with it, it was both high-tech and various buttons, which was daunting! But you only need to spend one day or two days – or take an hour more seriously, and patiently understand and understand the most basic things I said above, and then it will become more and more convenient and easier to use later. You will find that it can really save you a lot of trouble and avoid detours, and the efficiency of learning and experimental operations can also be improved by a lot – it is really worth spending time researching and mastering this little helper in the new era! It doesn’t mean that everything depends on luck, and hands-on and patience are the truth!
