The touch pointing input device used in notebooks has now changed markedly, or rather, there are already quite a lot of innovations in it, which we will discuss today in our article.
Discoverers
TrackBall is one of the very first technical innovations that replaced the familiar mouse. Sensor devices of this type are currently used not only in portable, but also in personal computers. This development is a mouse that looks completely different from the traditional one, but it's very simple and convenient to operate it. From the body of TrackBall stands a small ball, which rotates with the palm of your hand, and meanwhile all his movements are tracked by the cursor on the computer screen. Perhaps the biggest advantage of this device is that all users to it very quickly adapt. Of course, at the present time such devices can rarely be found. And in modern laptops they are not used.
The touch panel device and its predecessors
AccuPoint is a miniature manipulator, which is located in the center of the keyboard of a portable device. It operates according to the principle of the joystick, it is simple to operate, for this purpose it is necessary to tilt the element in the necessary direction, after which the mouse cursor will move in the same direction . Perhaps the main advantage of this device is that the manipulator itself has small dimensions. But, in order to learn how to apply it correctly, it will take some time. For a certain period, these devices have been very popular, but now they are difficult to meet.
Field for management
The TouchPad is a touch-sensitive pointing device used in notebooks. For certain the name of this element is familiar to each user. The TouchPad is located on the case of the laptop and has a size slightly larger than the matchbox. Apply this modern equipment is very simple. You just need to hold the tip of your finger in a certain direction, and in connection with this indication will move and the mouse cursor on the computer screen. If, for example, you needed to open something, then you need to press the pad twice, only this is done, respectively, quickly, as in the case of mouse buttons. The TouchPad is a touch-sensitive pointing device used in notebooks, which is now very popular, such equipment is installed on all modern portable computers. In some new models of devices, there is also the possibility of transmitting graphic information. To do this, you need to use the stylus to write the appropriate letter, and it will be immediately transferred to a graphical editor on the computer. As we mentioned earlier, the device is currently the most popular and is used on a large number of notebooks from various manufacturers.
A rare addition
TouchScreen is a touch screen device that is installed directly on the laptop screen itself. Nowadays, this technology is most often found in modern mobile phones, tablets, and portable computers. A wide distribution of such laptop displays have not yet received, because such components have a very high cost, and accordingly, manufacturers are not profitable to produce them on a large scale. For example, you can find such a device in Fujitsu notebooks of a special series, which belong to class B.
Wheel
Now consider the Jog Dial - this is a touch-sensitive pointing device used in laptops, which can often be found in the devices of Sony. The device is very simple. It is a small wheel that protrudes slightly from the body. In fact, this device is for the most part designed to adjust the volume, selection and launch of various applications, as well as to view and scroll through them. For example, in order to run a specific program, you need to scroll with the wheel, then perform only one click, and the selected item will be opened. Indeed, it can be noted that this device is very useful and, most importantly, user-friendly. By the way, in some notebook models this solution can be found together with the TouchPad. This option can be attributed to a portable computer HP, the model received a unique mouse, which is retracted into the case itself. It traces all movements by means of a movable plate, which is connected directly to the portable PC itself. This device is actually very convenient and does not require long user addiction.
