What is the scroll ball?
Scroll Ball Twisting the ball is equivalent to scrolling up or down with using a computer mouse’s scroll wheel. The cursor is still controlled by moving the ball. The scroll ball is intelligent and will send the motion type, ensuring that you need not constantly switch between scrolling and cursor modes.
How does a Mousewheel work?
Each wheel is made up of plastic spokes and, as it turns, the spokes repeatedly break a light beam. The more the wheel turns, the more times the beam is broken. So counting the number of times the beam is broken is a way of precisely measuring how far the wheel has turned and how far you’ve pushed the mouse.
What is the purpose of track ball?
A trackball is a computer pointing device which can perform the same functions as a mouse. Computer mice have small balls inside of them, and when a user moves the mouse, the ball rolls, causing the pointer on the screen to move.
What is the function of trackball?
A trackball is an input device used to enter motion data into computers or other electronic devices. It serves the same purpose as a mouse, but is designed with a moveable ball on the top, which can be rolled in any direction.
What does an optical mouse See?
An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface.
What is trackball used for?
In other configurations (sometimes called “natural scrolling”) the effect is inverted. On a mouse, the scroll-wheel can often also be used as a third mouse button by pressing down on it – a scroll button.
What kind of scroll wheel does a trackball have?
As with modern mice, most trackballs now have an auxiliary device primarily intended for scrolling. Some have a scroll wheel like most mice, but the most common type is a “scroll ring” which is spun around the ball.
Is there a way to scroll horizontally on a mouse?
Some modern mice can scroll horizontally as well as vertically, using a tilting scroll-wheel (introduced by Microsoft ), scroll ball (found, for example, on Apple ‘s Mighty Mouse ), pointing stick, touchpad (as on Apple’s Magic Mouse ), optical sensor, or a second scroll wheel.
Which is better twin scroll or single scroll?
More power and torque could be realized because there was more boost at the same engine speed with the twin scroll versus the single scroll. From 3,000 to 4,900 RPM, the increase in torque and power output grew as the engine speed climbed.
