High technology for a comfortable life: five interesting innovations

1. Always Call Home Cam

In September 2020, Ring introduced an interesting new product for home security systems. If traditional video surveillance cameras transmit images from stationary points, then the camera-drone always home Cam flies around the Home, conducting video recording. And while you are at work, you can see in real time on your smartphone screen what is happening at home. The device is completely autonomous: during the first flights, it independently creates a map of the location and determines the patrol route. However, the user can also set the following algorithm itself. In addition, the drone camera can be configured so that it rises into the air when the alarm is triggered.

The first ever quantum chess tournament was held in the world


As part of the sp2b 2020 virtual conference on quantum computing, an official “quantum chess” tournament was hosted for the first time in history. the winner was alexander kubica of amazon, who beat doug’s load of google. the latter do not have enough time to make the necessary calculations.

The author of this game is Chris Cantwell of Quantum Realm Games, who came up with it when he was a graduate student studying quantum mechanics. He wanted to transfer complex principles of quantum physics to the real world, adapting them for some practical application, but to preserve quantum nature itself. The choice fell on chess, as a game in which there is an almost infinite variety of situations on the field, so the player must be able to anticipate events and take into account the different probabilities of its occurrence. Just like in quantum computing.

Optical and laser: which computer mouse to choose?

Whether you use it for work or play, our hands are a gripping mouse almost every day. What is the difference between an optical mouse and laser mouse?

By choosing a mouse for yourself

They are on the shelves of stores in a huge assortment and are mostly intended for right-handers, while a few have an ergonomic design that is suitable for left-handers. Of all the features and shape factors, you will find two basic versions of the computer mouse: with an optical sensor or based on a laser. Which is better? Let’s figure it out.
Guess what? All modern computer mice are optical
modern computer mice are the same cameras that instead of capturing faces take pictures of the surface from below (table, stand, etc.). the images are converted to data to track the position of the periphery on the surface. Lastly, this low resolution camera in your hand is only designed to track X and Y coordinates thousands of times per second. Basically, all computer mice consist of a small low resolution (CMOS sensor), two lenses, and a light source. All mice optical, from a technical point of view, because they collect data in an optical way. but they sold as optical models rely on an infrared or a red led that projects light on the surface. this led is usually seen at an angle, focusing the light on the beam. the beam bounces off the surface, through a lens that magnifies reflected light, and transmits to a cmos sensor. The CMOS sensor collects light and converts light as particles into electric current. This analog data is then converted to 1 and 0, resulting in more than 10,000 digital photos being taken every second. These images are in relation to creating the exact location of the mouse, and then the final data sent to the PC to place the cursor every one-eighth of a millisecond. On older LED mice, you may have noticed that the LED pointed straight down and shone like a red width on the surface that the sensor saw. Now LED lights are projected at an angle and are usually invisible (infrared). This helps the computer mouse to track movements on most surfaces.

Why developers think AR will be more popular than VR

Virtual reality (VR) has taken the tech world by storm, but there is a consensus among experts who augmented reality (with) has more potential. They claim that ar will be the more ubiquitous of the two popular among vr and ar developers.

How is augmented reality better than virtual reality?

Augmented Reality (AR) encompasses a wide range of technologies and experiences, from creatures floating around your smartphone to images of Pokemon. Enterprising developers are already using Microsoft HoloLens glasses, where virtual reality blends with the real world, to create digital spaces. AR includes both the virtual and the real world. It makes virtual images more realistic, creating the potential for experiences that are very different from those seen in VR. With, in the end, will be more in demand, the reasons for this are its diversity.
