Why Oblique Mouse Cursor

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 .

Ars Technica The mouse pointer perpendicular originally designed , difficult to distinguish from other objects on 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 policy- makers of computer software up to date. 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 .
