Mengapa kursor mouse dibuat miring sekitar 45°

Pernahkah terpikir oleh kita, mengapa desain kursor mouse di komputer dibuat miring? Saking seringnya kita melihat kursor, mungkin pertanyaan itu tak pernah terlintas di benak kita.
Kursor mouse yang kita kenal selama ini umumnya berupa tanda panah tersebut dan ditampilkan miring sekitar 45 derajat ke kiri. Namun, tahukah bahwa sebelumnya kursor dibuat tegak? Lalu mengapa dibuat miring?
Untuk menjawab pertanyaan tersebut, kita harus kembali ke masa pada awal mula mouse dibuat, di era tampilan komputer masih berupa susunan piksel resolusi rendah.
Menurut penjelasan di situs Stack Exchange, mouse dan kursor pertama kali dibuat oleh Douglas Englebart pada tahun 1968. Awalnya, kursor memang dibuat tegak lurus ke atas.
Namun, saat komputer Xerox PARC dibuat sekitar tahun 1970-an, kursor kemudian dibuat miring. Alasannya, dengan layar resolusi rendah pada zaman itu, kursor mouse yang tegak lurus susah dicari di layar.

Ars Technica Pointer mouse semula didesain tegak lurus, sulit dibedakan dengan obyek lain di layar

Dengan piksel resolusi rendah, tampilan kursor sulit dibedakan dengan obyek-obyek lain yang ditampilkan layar komputer, apalagi saat itu tampilan layar masih monokrom.
Karena itu, dengan membuat kursor yang melintang 45 derajat, itu akan mempermudah pengguna mencari kursor di layar.
Setelah itu, kursor miring ke kiri temuan Englebart tersebut kemudian diadopsi oleh pembuat-pembuat software komputer hingga kini. Hal tersebut termasuk dilakukan oleh pencipta Apple, Steve Jobs, yang meminjam kursor tersebut untuk Mac OS-nya, dan kemudian Bill Gates dengan Windows-nya.

Reasons To Get A No Hands Mouse

By Marissa Velazquez

There are very many benefits which come with using the services of a no hands mouse. This is what makes it the best option which people should opt for in the market. One of the most important things that most people usually consider before buying anything is reliability. With these, this is an assured factor hence making it the most sought after devices.

One thing you should note with this is that you will get to move the cursor by using your feet. They kind of look like pedals hence very easy to use even for the first timers. This makes it an option which all people can take advantage of hence the best thing you could ever get.

You should also know that they are compatible with most of the operating systems people use hence making it an option which is open to all people. This makes sure that anyone who feels the need to get one is able to do so within the shortest time and enjoy the services. This tells a lot as to why they are growing in popularity.

Productivity is generally increased when you get one of these. This is simply because you will reduce the amount of time wasted by taking the hand off the keyboard so that you make sue of the mouse. The use of both feet and hands is one way to do more work in a very little time frame. This tells why most people have already had these installed in their homes and offices.

The pains which people usually complain of while using the ordinary desktop mouse is also done away with. This is one of the things which make people rest assured that the moment they get one of these then they will be assured good health while increasing their output. This is therefore a solution to people who suffer under the use of the ordinary mouse.

One thing which makes them very special is that they are designed to be very sensitive hence making them very simple to use. This means that you will find it very easy to move the cursor around despite the fact that you will be using your feet. Simplicity is one factor which is considered when designing the devices hence making them open to use by any Tom, Dick and Harry.

Getting these is made quite easy since all you have to do is find an online store and you will be able to make an order. This will only require a credit card and a computer. Given the fact that these are readily available to most people, this becomes an option which almost everybody can take advantage of.

Comparison of prices will play a huge role in determining how good of a deal you will get. With online stores it is even easier since you will do all this over the internet. The no hands mouse is therefore something you should try out and get to enjoy the services.
