Highlighting the touchpad and how to use the correct color for this song. Touchpad. What is it? Display of all running programs

Golovna / Additional functionality

The touchpad, otherwise known as the touchpad, was invented in 1988 by George Gerfeide. Then Apple Corporation licensed the yoga project and, beginning in 1994, began to win over PowerBook laptops. From that hour, the touchpad was the widest addition to the laptop. How is wine practiced - about the current release.

The touchpad is a flat touch panel to avenge a package of other boards. The panel is most often rectangular in shape with an area of more than 50 square centimeters. It is located below the keyboard and is lightly recessed into the body of the laptop.

The touchpad is based on a vibrating electrical circuit between a finger and a sensor or between two sensors. There are sensors for expanding the vertical and horizontal axes of the touchpad, which allows you to determine the position of your finger with the necessary accuracy. The surface is sensitively built with a grid of two balls of metal conductors, separated by a ball of thin insulating pads of mylar. Two balls of conductors play the role of plates, a gasket plays the role of a dielectric, and capacitors are molded on the crossbars of perpendicular conductors. With which balls are ripped in such a way that the conductors of one ball are perpendicular to the conductors of another.

After I add it, I will build an electric field between the capacitor plates. The microcontroller supplies voltage to two conductors, roztashovannyh at different balls, vimiryuє opіr mіzh them that memorize vimіryane value. Then we supply voltage to the other two conductors, rotting at different balls, and so it is repeated, the microcontroller docks do not die and do not save support between the skin pair of conductors, rozted at different balls. An hour, with the help of which the microcontroller achieves a reading from all sensors, one from the characteristics of the touchpads. After that, the appendix is transformed into the ultimate mode of work.

The human body is a good guide. When approached to a sensitive surface, the finger changes the electric field of the capacitance of the capacitors. The microcontroller vimіryuє opіr mіzh pairs of conductors and vіvnіuє vymiryanі values zі sberezhenimi in memory. Analyzing the measured values, the microcontroller determines the coordinates of the place of the torsional and vice that is to be repaired on the surface. The greater the pressure, or the greater the number of applied fingers, the greater the total capacity of the capacitor, which is fixed by the surface extension with those fingers. Through those that the touchpad works when the capacity is reduced, it is impossible to brush it with a pen or an olive.

Varto signify that no more than a finger is poured into the capacity of capacitors, but also other electrical fields and other physical effects. As a result, the capacity is constantly changing or shaking. For usunennya tremtinnya, "filtering" algorithms are used. The stench smoothes sharp changes in meaning. Most often, a simple algorithm is won, which is called the “averaging window” algorithm. Depending on the new value of the current coordinates, the average of the two remaining non-smoothed values is displayed.

The TouchPad (touch pad) can sometimes be included on laptops for any reason. In some cases, the coristuvachi turn on the touchpad, tk. Vіn can be set to active work with the keyboard of a portable computer.

Check out the options for enabling the touchpad. Ale, if you choose, you need to be sure that you have a brand of laptop. On the right, there are different methods for activating the touchpad for different models.

Let's take a look at how you can turn on the touchpad on a laptop for more help.

Laptop re-engineering

Regardless of the model and brand of a portable computer, it will be the first time to resolve the problem and be re-advanced. It doesn't matter if you have a Windows 7, Windows 8, Ubuntu system, or else, maybe, you just had a one-time pardon and after re-advancement, everything will go to its place.

Victory keys.

On most laptops, a special combination of keys has been transferred to enable/disable the touchpad. Only for different brands won't be taken care of.

With the alternative method, it is necessary to simultaneously press two keys on the laptop keyboard: the Fn key and one of the function keys at the top row (F1-F12).

For different brands and models of portable computers, the combination of three is different. For example, for Asus laptops, it is necessary to type the following: Fn + F9.

Highlighting the touchpad on Asus laptops

Axis list of keyboard shortcuts to enable the touchpad for the most popular brands of laptops:

Asus - Fn + F9 or Fn + F7
Acer - Fn+F7
Lenovo - Fn+F8 and Fn+F5
Dell - Fn+F5
Sony - Fn+F1
Toshiba - Fn + F5
Samsung - Fn+F5

There is no HP brand on the list, so on Hewlett-Packard laptops the inclusion of a touchpad is behind an additional green key, specially seen for this function. If there are no such keys, then, more than anything, for the purpose of seeing this task, it is necessary to work under pressure (or more pressure) at the upper left corner of the touch panel (marvel at the video below).

Enable touchpad in bios

If you don’t have a touchpad and don’t help in the front, it’s possible that it’s just a fault in the BIOS settings.

Go to BIOS and find the item Internal Pointing Device. The value of this parameter can be Enable, then. noted.

Install/reinstall drivers

Also, the reason for the non-practicality of the touchpad may be due to the incorrect operation of the driver in the annex. Such a situation could have been reinstalling Windows as much as possible, or it could have become something of a bug.

In this case, you need to try to install the touchpad driver from the disk (for this reason) or get it from the official site of the virobnik.

TouchPad by Synaptics

Synaptics touch panels are often found on today's laptops. Possibly, your portable computer also has the Touchpad of this maker installed. In this case (due to the presence of drivers), the touchpad can be connected behind an additional keypad.

For whom it is necessary to go to the Windows recovery panel and select the "Misha" item.

On the tab "Settings" for additional buttons, you can turn on or off the touch panel.

Also, for certain versions of drivers on this insert, you can have it set up, as it allows you to turn on the touchpad when you connect a USB mouse to a laptop.

Touchpad is not working

As if all the above-mentioned recommendations did not help you, it is possible that the reason for this is a physical breakdown of the touch panel, or simply contacts were made. I have one type of day out - sort out a laptop and review all the details. In extreme cases, you may need to replace the touchpad. If you don’t get it right, it’s better to entrust your work to professionals.

Misha, a touchpad, a trackball - all these words are well known to the masters of laptops, as they brought their first electronic assistant about a dozen years ago. However, the popularity of mobile computers is growing, happy lords are growing more and more, and the flow of information is such that some people simply do not have time to know the history of the development of technologies.

As a result, once in a while, the power “touchpad - what is it?” sounds. Today we explain what is possible on the basis of this term, and also guess the main milestones in the development of such outbuildings.

Mobility in the first place

Another name for a laptop is a portable mobile computer. Head yoga vіdminnіst vіd povnotsіnnogo system unit - tse mozhlivіst take yoga with him that hour of pracsyuvati without zvnіshny zherel life. Obviously, the optimal solution is a monoblock if all the key extensions are combined in a single building. There are no other keyboards, a bear and monitors, like in stationary systems. While operating systems were already popular among the first laptops, retailers needed to come up with attachments that would mimic the functions of a bear, and at the same time, part of a monoblock. The task was brilliantly completed.

Teddy bear uphill paws

In portable computers, the troch below the block of the keyboard began to place a small attachment, which I use and two buttons. Provіvshi doloneya on kuli and grafted yogo in ruh, you can use the cursor at the programs.

The principle of robotic buv, like the best bears at that hour. Such a decision took away the name "trackball".

The keyboard is from the touchpad

Prote the trackball maw is low nedolіkіv, so the robots didn't try to find alternative solutions. And now, with the appearance of touch panels, near the gallery equipped with laptops, becoming a right technical breakthrough. Those that have been proponated are successfully victorious and dosi. On the trackball space, they began to place a small rectangular plate, as if functionally replacing the bear. Oh, touchpad - what's up? Danish attachment is structurally part of the laptop case and the keyboard is ruffled at the bottom.

Dotik finger to the panel and її moving along the surface are accepted by the controller, converted to smart coordinates and transferred to the working program. The sensor is of a seminal type: it is easy for someone to cross over, having tried to swipe with the cursor, having hit the panel with an insulating object, for example, an olive - there is no reaction. Under the pressure of the buttons of the bear, it was replaced by two swedish last dots to one pretty point on the panel. To replace the bears in the touchpad, two or three (deposit in the model) mechanical buttons. The function of the ring is also implemented: it is necessary to draw a finger uphill or down on a large small block (a flake of parallel males). For some laptops, for rewinding, it is necessary to move two fingers on the sensor at the same time. As a rule, the price of new models that support multi-touch technology (multiple dots).

Touchpad: what's up?

Like a bachimo, for a little-witted name, one wants to do it with simple functions. So often used by computer technology, if a lot of terms are taken from foreign language. Otzhe, so to speak more simply, the power of "touchpad - what is it?" You can confirm that this attachment is a touch panel, recognized for the functional replacement of a computer bear.

Vinaisov touchpad one man, call yogo George Gerfeide, in 1988 roci. In less than an hour, the Apple company extended the license for yoga wine, and began to victorious "touch maidan", starting from 1994 until today, with its PowerBooks. This river, indeed, having become a progress in the gallery of counting technology, and even today, we are basking in such a necessary “maydanchik”, which, before speech, can be replaced by a bear, and not wondering about those, " how does it work?".

Robotic principle

Robotic principle the touchpad is not too foldable. Yogo robot is based on vimiri capacities or fingers, or capacities between sensors. So called optional sensors, expanding the horizontal and vertical axes of the TouchPad*a, allow our “touch pad” to designate, for some part of the rotation, a finger, tobto. indicate the position of the finger with the necessary accuracy. If you marvel at the TouchPad from the physical side, then the wines of power number of metal conductors that make up the network. Distribution of services insulating gasket from lavsan plіvka, yak can milk rosemary. Through those that the touchpad works when vimiryuvannі єmnostі, koristuvatisya him є impossible whether it be a pen or an olive. Describe all the calculations, how the touchpad vibrates, there is no sensation, because. everything is vlashtovano already nadto foldingly.

Rozmir, the fortunes are not good

The touchpad, which is attached, which takes a meagerly little time, which, indeed, is enough for the user in everyday life at the laptop (it is easy to use the touchpad when the sides of the browser are choked, and when there are system add-ons and for simple games). Ale, respect that in online / 3D shooters you have a lot of work, and also you have a warehouse for working with photoshop.
The touchpad sings victorious in laptops, but yoga can also be used. For which I will add no drivers and third-party programs. The touchpad will be especially needed there, since there is no possibility of victoring a big mouse, for example, in the subway, by train, in a car, etc. Ring out, all the touchpads are protected from falling into the middle of the saw of the abologists. The touchpad is guilty of serving you for a few hours, usually 5-6 years! I would also like to present a list of touchpad advantages:

For a robotic touchpad, a smooth surface is not needed, that great expanse
To move the bear around the screen, you don’t need to swipe your finger across the touchpad, but to do a small shift
Before the touchpad, it is not necessary to call and mother especially the buttons, because. calling to the new one is easy and calling yogo is also easy
Water-, sawn-resistant
By itself, the wine does not break and serve you for a long time

Later, I concur, at this statute you have recognized for yourself a lot of cicato and acknowledgment. Especially for myself, I found out that the touchpad is waterproof, and that the principle of yoga robotic foundations is based on a large number of sensors.

On what road the reader ended the article, until the end

A laptop is a mobile device, which can be effectively used both in a full-time work place, and in idle minds, for example, in transport. The touchpad is one of the quietest additions, which ensure mobility. It’s important for those coristuvachas to know how to turn on the touchpad on laptops.

The next thing you see in front of you is the victoriousness of the bear. Here it is necessary to go to the tab "Settings" (another tab may have a different name, for example "ELAN"). On the tab "Settings I will add" there can be a button "Umknuti". Click on this button and save it by clicking on the OK button, as it appears at the bottom of the window.

The next step is to indicate that on the “Settings I will build” tab, the “Removing the calling bear” function may be available. If it is active, then the touchpad is not practical, if a larger computer mouse is connected to the computer. If you want to disable the touchpad and the bear at once, then disable this function.

If you have checked all the ways to turn on the touchpad and nothing helped, then your touchpad may have been disabled through the BIOS. In this case, in order to enable the touchpad, you need to enable the function under the name "Internal Pointing Device". As a rule, it is listed in the "Advanced" section.

Well, the BIOS is also all-inclusive, but there are only two options: no drivers are installed, or the touchpad is broken.
