Your work meetings like with the holograms of ‘Star Wars’ thanks to 5G

Published

on

The three-dimensional image of Princess Leia broadcasting her distress message is part of popular culture. Even those who have not seen the films of the saga, easily associate the holograms with Star Wars. If anything, holographic technology has a promising path ahead. The arrival of 5G will allow heavier images to be transmitted through networks. In this way, it will be easier for these 3D images to be adopted as a standard in communication between people.

Video calls, so common since the pandemic took over our routines, could be made using a 3D hologram. It’s not just the speed of the network that will influence our ability to deal with holograms. Also the low latency. These two aspects, of paramount importance in 5G, will allow images to be transmitted properly and not be unbalanced or suffer interruptions.

The origin of holography

The differences between holography and photography are obvious. The second captures a two-dimensional snapshot, while the first offers three-dimensional or multidimensional information. When the viewer moves they will see different angles of the projection and this will make sense at all times.

This result is reached through decades of research. One of the pioneers in this field was Dennis Gabor, who studied Mechanical Engineering at the Polytechnic University of Budapest and the University of Berlin. There he began to work in one of the physics laboratories of the Siemens company. Following Hitler’s rise to power, he was forced to leave Germany because of his Jewish origins. And it was in 1947, in the United Kingdom, when he happened upon a new method of forming images on a circular transparent slide. He called that technique holography, for ‘holos’ (everything, in Greek). Its discovery went unnoticed at first but years later it gained international recognition. So much so that in 1971, Gabor received the Nobel Prize in Physics.

How holograms work

It can be said that a hologram is a record of the interference that occurs between two beams of light when the light from one of the beams reflects off the object. This registration is carried out with a laser beam on a photosensitive film. From there, it is possible to generate a three-dimensional projection of the image.

When it comes to image projection, it’s really just a matter of having the right receiving device. “Holography works the same as live streaming, but changing the final screen for a holographic device”, point out from the technical department, specialized in holography. “Although it is always necessary to follow the specific technical parameters of lighting and recording.”

5G as a boost for holography

In the field of holographic images, 5G will be a boost. The graphics are very heavy, so the high speeds offered by the new generation of networks are adequate. But also its low latency, thus avoiding interruptions. Otherwise, the projections may suffer cuts and decompensation.

“Currently enough powerful network connections are needed to avoid delays in full HD broadcasts,” they point out from 3DH. “ With the arrival of 5G we hope to avoid these delays and to be able to broadcast in 4k without problems . It will help us a lot in the retransmission of holographic images ”.

There have been several pilots who have made video calls with holograms via 5G networks. And this is one of the applications being considered as a driver of the new connectivity. It is based on augmented reality. Two people could sit quietly chatting, each with the other’s hologram.

It seems like a thing of the future, but in 2017 the first international video call was already made. It was made between Seoul and New Jersey. In South Korea, KT Telecom, one of the participants in the project, pointed out that this type of communication would be available with the new 5G. The idea is to provide a greater sense of reality. From the flat image of video conferencing, it would move to a three-dimensional one, which would capture much more detail, such as body language.

The following year another milestone took place in the field of holography. Mischa Dohler, a professor of wireless communications at King’s College London and a music composer, demonstrated the capabilities of the technology at a concert. It was a live event, where he acted as a pianist on stage while his daughter sang through a hologram. The holography showed the girl a few meters from the piano, singing to the rhythm of her melody. The two were 1,000 kilometers apart, but the latency was minimal, so the result was impressive.

It’s just two glimpses of what holograms can do. From 3DH they list, as the main applications of technology, ” communications, events, exhibitions, fairs, shops, and businesses “. Although they point out that they are currently developing “new holographic applications for education, in schools, and the cultural sphere, for museums.”

Meetings via holographic telepresence

With current technology, it is possible to generate video calls with holograms. This is what the project offers a telepresence system that shows an assistant remotely through volumetric video. For this, augmented reality techniques will be used. Participants in this holographic meeting will have to wear HoloLens 2 type glasses.

The remote assistant will be staged in a 3D augmented reality figure. The idea is that it can be observed from all angles. A factor that will be useful for training in different areas, such as rehabilitation techniques or medical interventions. But objects can also be displayed in 3D, which will be useful when examining prototypes in industry, for example.

It will be necessary to deploy a volumetric capture room. This will feature multiple depth cameras, such as Intel’s RealSense. What they will do is capture the 3D figure of a person in real-time. From there, the images will be generated using Evercoast software. To send them, considerable bandwidth will be needed and here 5G comes into play. Thanks to edge computing processing, multidimensional images can be served to meeting attendees.

Video calls with a 3D hologram on mobile

The next step is to take the holograms to much more everyday terrain. This is what some initiatives that have put smartphones in the spotlight are looking for. From these devices, they have been able to generate holographic images, although not always with good resolution.

One of the methods used is simply an optical game to channel the light, with a simple pyramid projector. Of course, it is not the most advanced, but today almost all holograms generated with smartphones need some type of projector. Although some have tried to create them using only miniaturized technology, integrated into the smartphone, such as HoloFlex. For the moment, the results have to improve.

In this context, engagement on Facebook is very important for your brand to be seen, after all, you want to be where your customers are.

If, however, the number of likes, comments and shares on your page is declining and you’re experiencing a drop in engagement, we have the tips you need to get out of that situation!

Engagement with posting on Facebook is basically every action the user takes regarding what you post, i.e. the number of likes, comments and shares.

How to increase engagement on Facebook is a concern of every account manager.

Likes represent people’s approval; comments generate discussions about the topic you are doing, increasing interest; finally, shares increase the reach of your post.

There’s also the number of times people tag your profile in posts, and if you have a physical store, engagement can include the number of check-ins at your location.

As you can see, an engaged audience brings many advantages to a brand and, therefore, one of the concerns of every marketer and influencer is how to increase the reach of posts on Facebook and the number of interactions.

How to increase engagement on Facebook? 

How to increase Facebook engagement? How to increase the number of followers? How to increase the visibility of a Facebook page?

All of this is possible with these 7 must-see tips that we’ve separated for you to get more engagement for your social network. Follow along to find out what they are.

7. Buy Facebook Likes for ultimate growth

Another answer to how to increase engagement on Facebook is to buy engagement for social media. You can buy likes, video views and even comments.

These numbers increase the reach of your posts, making more people access your content.

SuperViral.Ca is an excellent place to buy followers online reliably, securely and confidentially: no one will know that interactions were purchased, as they are made by real profiles.

That’s what you’re reading, no fake profiles. See how easy it is?

  1. Use Hashtags

Hashtags are part of all social networks. They are tags or keywords that are associated with a topic that you want to be indexed explicitly in the application.

It is not uncommon, for example, that the pages of bars and restaurants use hashtags such as #food or #whereto eat in their posts: this way, every time a network user searches for these hashtags, they will find the establishment’s page.

In other words, the use of hashtags helps to increase the visibility and the number of likes of your posts and, consequently, the number of visits to your website.

Some tips you can follow when making your hashtags:

  • Don’t write too many words together as they leave an ugly aesthetic;
  • Research the hashtag before using it, so you can choose the hashtags that are hottest;
  • Use a hashtag that matches your post — your hashtag should refer to the topic or product you want to cover.

2. Use a CTA

Finishing your posts with a call to action gives your followers a suggestion for interaction.

It can be through phrases such as “tag your friend” or “leave your comment” or, more quickly, leave questions: “what do you think?”, “did you like this product? Tell us.”

Other than, followers are also important metric especially for personal profiles. But if you buy Facebook Followers Australia from any trusted website then it becomes easier for you to rise above the competition. 

3. Be brief

The first 5 hours of a Facebook post’s life represent 75% of the engagement it will have.

To give you an idea, it takes people between 1.7 and 2.5 seconds to look at each post while scrolling through the feed.

This means that your post needs to get attention as soon as the user passes through it.

So keep your post short to get attention quickly and get people involved with your post.

4. Use images

Using images is one way to increase your engagement. It can be a simple photo, as long as it is beautiful.

For someone who is selling a product, for example, the photo can be of a customer or of the item that you want to sell.

For influencers, it could be a photo of themselves or something related to the topic they’re proposing.

A travel influencer, for example, might post a photo of the last trip he took or the place he wants to talk about.

5. Post consistently and on time

The Facebook feed is based on an algorithm: not everyone sees your post at the time it was posted. Still, it is important that the post is done instantly with more users using the network.

A good window is between 9 am and 7 pm, when there is a greater number of accesses.

The most important thing is that your posts are done consistently so that the public sees your content regularly.

6. Make videos or broadcast live

Video posts generate more engagement than photo posts.

In turn, live streams have the highest engagement of all, with 6 times more interactions than regular posts.

Conclusion

Gaining visibility on the internet is the goal of everyone who wants to succeed through Facebook.

With the help of Seguidores.com.br, increasing your engagement is much easier, helping to achieve authority and popularity on social media.

Add more RAM memory to your laptop in a simple way and without breaking anything

Published

on

As in our desktop PCs, the RAM memory of our laptop can also be updated. At least, in the vast majority of models. However, the process of updating it can be much more complicated than with our desktops. Even so, it is not so complex that I can put you back from doing it. And, by taking several precautions, it is something that you can finish in just minutes.
Laptops sacrifice expandability in exchange for gaining portability, however there is one element that we can expand and this is RAM. An operation which is in principle simple, but which can have the appearance of complex. So that you are not afraid when making this hardware update to your PC, we have prepared this tutorial for you.
Reasons to expand the RAM of our laptop
With the change in usage habits, the consumption of RAM memory in our personal computers tends to increase, usually due to the following factors:
A greater number of tabs open in the browser.
Having several applications open, even some that we do not pay attention to.
Use of very large files.
In a desktop PC , this circumstance has a fairly simple solution: buy more RAM memory modules. If possible, the same make and model as the RAM that you already had previously installed and in laptops the same thing also happens, of course you have to make sure that it has SO-DIMM modules on the board, since you can find with problems when expanding the memory of the same.
If you are one of the people who works with heavy applications that require a lot of RAM, you will notice the difference in performance in the system and it will not suddenly become slower due to the fact that it is out of memory and the applications will not drag as before.

Laptop RAM is sold in SO-DIMM format

Unlike the RAM used in desktop PCs, RAM for laptops has a different format . This format is called SO-DIMM. And it’s quite a bit smaller than the DIMM format of RAM our desktops use.
Therefore, before doing anything, you should check what model of RAM your laptop uses. And find out if this one has a single RAM slot, or two. In the first case, the only way to update the RAM is to remove the original module. And change it for one of greater internal capacity. But of the same make and model as the one we have installed. In the second case, we should buy another SO-DIMM module identical to the one we have installed.
We want to place special emphasis on this aspect. Since laptops tend to be more delicate in terms of the RAM memories with which they work and therefore it is essential when choosing the DIMMs that we are going to buy.
Without SO-DIMM you cannot expand the RAM of the laptop

Before thinking about updating the RAM memory of a laptop, the first thing we should know is if our laptop is going to allow such expansion. We comment on this because, there are laptop models where the RAM is soldered to a PCB. And it cannot be expanded in any way. If this is the case with your laptop, we are very afraid that you will not be able to expand the RAM.
Because LPDDR4, LPDDR4X and LPDDR5 memory are not sold in DIMM or SO-DIMM format, but memory manufacturers sell them to be soldered directly on the chips to solder them to the main PCB of the laptop, in these laptops their RAM memory does not can be enlarged. So when you go to buy a laptop take a good look at the type of RAM it carries.
To find out if your laptop allows you to expand the RAM, you must locate the laptop’s maintenance manual. Most brands usually publish the specifications online, usually on the support website for each model.
How to expand laptop RAM

Before starting to handle our laptop, the essential thing is to disconnect the battery. Failure to do so can create a short circuit when touching the components inside the notebook.
Once we know for sure that we can update the RAM of our laptop, we must locate the slots where they are inserted. Some laptops have dedicated openings on the back, from where we can manipulate the RAM.
But, unfortunately, this is not always the case. And in many laptop models, you will have to remove the back of it to access the slots.
Be that as it may, to place the new RAM, we must insert it in the slot that we have free. We must introduce it, so that it forms an angle of between 30 and 45o with the horizontal.
With the module fully seated in the slot, it is time to press down so that the two side metal retention rods in the slot begin to retain the SO-DIMM.
Do not close your laptop yet
Once we have the RAM properly installed, do not close your laptop yet. It is time to check that everything has gone well during the installation of this. Therefore, connect the laptop to the power cable, without first connecting the battery.
Now, the only thing left to do is boot up the computer and check that the new RAM is recognized by it. Something we can do directly inside the BIOS, if we are in a hurry to check. Or we can wait for the operating system to load, and check it in the Windows Task Manager .
If everything works correctly, now you can turn off the laptop, disconnect it from the power supply, and close it completely, unless you want to use it and enjoy the extra performance that the RAM expansion will give you in many of your applications PC

Why should you add/upgrade graphics cards on your PCs?

Published

on

It is possible to greatly enhance a computer’s performance by installing a graphic card. If you want to see a performance boost, you’ll need a new graphic card. A PC with a better graphics card can play better games. Additionally, the card may enhance the computing experience by enhancing video playback and freeing up memory. It is possible to add a graphic card to a computer, preload or incorporate it into the motherboard.

Improved Playing
Having a better graphic card may help gamers play better.
The performance of a computer may be considerably increased by installing a better graphic card. The graphic card is the most crucial piece of gaming gear. An insufficient graphic card may severely limit a computer’s capacity to play games, especially if the game’s requirements are high. If a game requires a high-quality graphic card, the default video card will not perform as well as a newer, more advanced video card. Adding an up-to-date graphic card to a computer that is a few years old may let it play games almost as well as a newer machine. Adding a new graphic card to an older computer is frequently less expensive than purchasing a new computer.

Enhanced Video Capability
With the addition of a graphic card, you’ll be able to edit digital videos better. Video playback and editing may be improved by installing a graphic card. A video editor’s productivity may be boosted by using a high-quality graphics card. High-definition video and multi-video playing need the use of a graphic card, which has its memory and resources, to increase playback quality. In addition, a graphic card helps a computer “fuse” (process a new video) more quickly by processing and compressing video.

Memory Can Be Freed
When a graphic card shares memory with the computer, it depletes the computer’s resources. Some built-in graphic cards have their dedicated memory, while others share the computer’s memory with others. When a computer’s built-in graphic card uses up all of the computer’s memory, adding a graphic card will free up that memory for the computer to utilise for other tasks. Even if the new graphic card is equivalent to the computer’s built-in card, installing a graphic card may boost the computer’s performance. A graphic card’s built-in memory is frequently quicker than the computer’s RAM, which might help enhance speed.

Streamlined Computer Use
The performance of your computer may be improved by installing a graphic card. Installing a graphic card may make your computer experience more enjoyable, even if you don’t need it to perform what you want it to. It’s common for newer operating systems to include new graphical capabilities that the built-in graphic card may not show smoothly. It is especially true for newer operating systems like Windows, Mac OS X, and Linux.

Differentiation between Graphics and Video Cards
Basic computer hardware knowledge will help you comprehend the advantages of video cards over integrated graphics; nonetheless, there is no such thing as an integrated graphic card or a video card.

Hardware for a computer
The motherboard is an essential part of any home computer. CPU, RAM, and a graphics or video card may all be plugged into the motherboard, as well as any other significant gear that may be present.

Integrated Visuals
A computer with integrated graphics implies that the motherboard handles the computer’s capacity to analyse visual data, such as in movies and video games. Integrated graphics have the advantage of being cheaper than a separate video card. However, this comes at the expense of lower visual quality. Integrated graphics may suffice if all you need your computer for is viewing a film.

Animated/graphic cards
The processing requirements for visual data in video games are much greater than in other media. Because it relies on the CPU and RAM for resources, integrated graphics often perform poorly in computer video games. Graphic cards fix this issue by offering a separate piece of hardware that may be plugged into the motherboard for visual processing purposes alone. If you’re looking to save money, a video card is a great option. Even a low-end one will surpass most integrated graphics.

To breathe fresh life into an outdated computer, you may want to consider upgrading your video card. It’s becoming more difficult for outdated graphic cards to keep up with the demands of modern games and operating systems. You can only increase your computer’s performance by purchasing a more powerful graphic card since the only method to increase visual memory is to buy more RAM. In less than an hour, you can swap out your graphic card.
