What’s the difference between Virtual Reality and Augmented Reality? What does HMD mean, and what the heck is an omnidirectional treadmill? What does latency and screen refresh rate have to do with it? In our Virtual Reality glossary, we’ll explain the most important terms from the world of VR.
The most important terms in VR explained
3D-Audio: 360°sound for VR headsets. The sounds will be played back through the headphones to match what’s happening in game.
Augmented Reality (AR): In Augmented Reality, the real and virtual world are being combined. Images or videos from the real world are combined with additional information in real time.
Although perhaps the most usual is to use Window with a single user account, it is often necessary to have multiple accounts, especially on shared computers. This makes things a lot easier when we share the computer with our siblings, roommates or if underage users have access to the PC and we want to control their access.
For this, Microsoft’s operating system offers the possibility to create different users accounts, to manage, eliminate, or to give them certain privileges. That is why, we are going to share below a small guide on user accounts in Windows 10, how to create a new account, enable a guest account, change to administrator account, delete accounts, etc.
Create a new user account and rename accounts
If you want to create a new user account, then the first thing you have to do is go to the Windows 10 Settings page from the Start menu and select Accounts. Once you do this, enter the Family & other people section and you will see in the right panel the options of adding a relative or another person. If you want to create an account for anyone then choose the second option, then enter their email account, click next and it’s done. If you do not have access data for that person, then you can click on this option and indicate the email and password that you want to use to log in to the system.
If on the contrary you want to create a family account, then select the add family option. This makes it possible for all family members to set up their own login and desktop or to make children not have access to certain websites, applications, games or even set time limits for using the PC.
Microsoft’s operating system offers the ability to create user accounts so that each person who uses the same computer has their own account to manage their files and applications with the necessary permissions. When we turn on the computer and start the operating system, we will see the Windows 10 login screen. In this screen, we can see how the list of the active user accounts in the system appears in the lower left corner.
Just by choosing your account from that list and entering the password, you will login to Windows 10. However, there are some tasks or functions that will only be available to the computer’s administrator user, such as being able to manage these user accounts. The system administrator will be the one that can create, delete, activate or deactivate a user account in Windows 10.
Numerous users have complained that the image inside the PlayStation VR headset moves to one side as time passes. It is a problem that doesn’t seem to affect all users and some even report that it is more pronounced in some software than in others. Now, Sony has addressed this problem and posted an article …
PlayStation VR just hit the market this week and has become many people’s introduction to the world of virtual reality. The following list of tips and tricks is supposed to improve your PlayStation VR experience. If any of the terminology sounds unfamiliar to you, we recommend you check out our virtual reality glossary. If you want to know how to set up PlayStation VR just have a look at this article.
Optimizing the Tracking
Playstation VR uses a camera in combination with LEDs on your headset and the PlayStation Move controller (Dual Shock 4 controllers can also be recognized). This method is of course less than subtle and these bright lights reflecting of off shiny surfaces can become a little irritating. That’s why we recommend darkening your room for PS VR. If you don’t need to have the Social Screen displayed on your TV you can just turn it off.
Almost everyone has its own user and password to access Windows. A measure that although it protects us so no one can access our computer and dispose of the information have in it, it’s not entirely reliable. Because in case our laptop is lost or stolen, anybody could have access to all of our information if they boot the computer through a CD, DVD or USB, or even installing another OS.
Therefore, if we want to improve our data security, besides encrypting, we can set a Hard Drive booting password and avoid that someone can start the system easily. For this, we have to enter the BIOS or UEFI and in its settings add a password to block the computer so no one can start it up without it.
According to the manufacturer, the method to access our computer’s BIOS may vary, though normally you can enter by pressing any of the keys Supr., F2, F10, F12, Esc, etc. while the computer is starting. If we don’t make this way, then check the user manual or contact the manufacturer.
How to block from BIOS or UEFI our computer so no one can start it
Once in the BIOS we must look for the HDD password option that will probably be under the security tab. Due to that the menu options may vary from one manufacturer to another, in case you don’t find the option, it’s advisable to check the user manual of the motherboard. Once we have found this option, we will set a safe password and after that restrict the start mode so it can only be booted from the hard drive so blocking your computer.
Since its creation, over 40 years ago, The BIOS has been the tool through which we can manage our computer’s hardware. And the thing is that if we would like to choose which device to initialize during the booting process, configure RAM or graphic card frequency, adjust fan speed, among other things, the only way we have to do all of those is to access the BIOS and change the settings.
Barely 6 years ago and thanks to an important agreement held by the main technology companies, it was decided to replace the BIOS for a new system called UEFI. A new standard that was introduced commercially soon after and that offers various benefits in comparison to the BIOS.
USB-C is made to offer a large range of data connectivity, and also provides the same power supply capability as the proprietary power adapters used now. This makes it so that with just one charger and just one cable we can charge at high speed any kind of devices.
The USB-C adapters of certain capacity can work at different voltages, but they always offer compatibility with devices with charge modes of less capacity and intensity. In other words, if we were to buy a laptop with an USB-C charger, we will find voltages between 20 and 5 volts. This is standard and is precisely made to promote the universal use of just one charger for all devices.
A MacBook Pro 2016 charger with 20, 9 and 5V modes.
It has four voltage standards: 5, 9, 12 and 20v. The intensity will vary according to the needs of each device and the charger will adjust the intensity to it as well. The maximum power transfer will also vary according to the voltage and the charger.
If we’re going to talk about web browsers, it is worth mentioning that Google Chrome is the most used browser by users worldwide. And that is because in addition to all the features, functions, settings and configuration options, you can get more performance from Google’s browser making use of the large number of extensions available in the Chrome web store. Web browsers are linked directly to Internet browsing and searches on different search engines, which are the ones that allow users to perform searches on any topic or a particular website.
However, modern browsers do not index the entire web page when making suggestions to the user based on pages visited or marked as favorites in the past. Because of this, although on many occasions you obtain results based on the index of the title of the page or its URL, when you can’t remember the URL or the website’s name you have to look in the browsing history for the previously visited site that you couldn’t remember.
Without a doubt, a very heavy task that can be very time consuming and that will be much easier thanks to WorldBrain, a Google Chrome extension that indexes all web pages visited or marked as favorites to allow you to search for them in the browser’s own address bar.
Surely on more than one occasion you have said or heard someone say a computer is running slow, especially on older computers, as more and more powerful applications are being developed and therefore more resources are needed. RAM is one of the key components in computer performance, although other components such as the processor itself or the hard drive are also important in this regard.
Sometimes we decide to change computer the minute we start noticing it becomes slow and that there is no way to optimize its performance through software, however, you should first think about the possibility of making some changes in the hardware to extend the life of our PC or laptop much more.
Undoubtedly, changing from HDD to SSD can help you a lot, but in many cases users think first about increasing the RAM of their computer. However, several doubts may arise here, how much RAM do I have installed right now, what type, how much RAM does my computer support, how to know if I have room to install more RAM and how do i install it.
