Why Mouse Cursor Italic?

Has it occurred to us, why the mouse cursor on a computer design made ​​crooked? So often we see the cursor, maybe the question never occurred to us.

The mouse cursor that we know it is generally in the form of arrows and shown tilted about 45 degrees to the left. However, you know that before the cursor created upright? Then why made ​​crooked?

To answer this question, we must go back in time to the beginnings of the mouse is made, in the era of the computer display is a low-resolution pixel array.

According to the explanation on Stack Exchange sites, the mouse and the cursor was first made by Douglas Englebart in 1968. Initially, the cursor is created perpendicular to the top.

However, when the computer Xerox PARC made ​​around the 1970s, the cursor is then made oblique. The reason is, with a low resolution screen at that time, the mouse cursor perpendicular hard look at the screen.

With the low resolution pixels, the display cursor is difficult to distinguish from other objects displayed a computer screen, especially when the display is monochrome.

Therefore, by making the cursor across it 45 degrees, it will be easier for users looking for a cursor on the screen.

After that, the cursor tilted to the left Englebart findings are then adopted by the computer software makers until now. This is done by including the creator of Apple, Steve Jobs, who borrowed the cursor to the Mac OS, and then Bill Gates with its Windows.
