A 4D mouse has four directional movements, making it useful for scrolling both vertically and horizontally. It can benefit those who spend long hours on the computer and is faster and easier than traditional scrolling methods. It may also have programmable buttons and can be wired, wireless, or optical.
The “4D” in the name of a 4D mouse refers to four directional movements. This pointing device can scroll a page both vertically and horizontally, or up/down and left/right. Having an extra direction of movement is useful not only online but also in spreadsheet applications and graphics programs. It’s also useful for quick mouse positioning in games or for drawing large projects in graphics programs.
Scrolling is an extremely useful feature, especially when browsing the Internet. Most websites require visitors to repeatedly click the small window up/down arrows or drag the vertical bar to scroll down the page. A 4D mouse makes this repetitive and somewhat annoying task as easy as rolling a ball with your fingertip. A page that does not fit into horizontal view can be viewed using the horizontal roller.
Studies have shown that repetitive motions like clicking a mouse button can cause carpal tunnel syndrome and finger pain. For those who spend only a few hours or less each day on a computer, this may not be a problem. However, the millions of people who spend eight or more hours a day in front of the screen may find this type of mouse very beneficial.
Aside from the physical relief, scrolling with a 4D mouse is easier and faster than repeatedly clicking an arrow or dragging a scrollbar. The screen moves smoothly and can be stopped effortlessly in any position by stopping the scrolling motion. There is no longer a “screen jump” when the mouse accidentally slips off the arrow or vertical bar.
This mouse may also include programmable buttons that can be used for back and forward page functions or other tasks. It can be wired, wireless or optical. Many laptops have a 4D mousepad built into the keyboard. Sliding your finger horizontally along the bottom edge of the pad scrolls the screen left and right, while sliding it up or down the right edge of the pad scrolls vertically. Some keyboard manufacturers also offer desktop keyboards with built-in 4D pads.
