Why there is a dot(.) on 5 key of every cellphone?
Wed, Apr 28, 2010
Have you ever noticed while typing on your cellphone, having small dot on number 5 key if not check it now.There is also small raised bar on the “F” and “J” keys of keyboards.
The reason behind on putting dot on keypads are pretty simple,In the early days, items with numeric pads, such as caculators and adding machines were used almost exclusively by accountants and the like. Since they had to perform a lot of caculations fast, most learned a method of using the keypad without looking at it. The dot was added as a reference point, so you could identify the 5 key by touch.
It’s given so you can locate where your finger is on the keypad without having to look…Mobiles have the dot on the number 5 key on the keypad, and computer keyboards have them on the the F and J keys.
5 is in the middle – and this is a way for you to type and not look at the numbers – move your finger to the 5 and you know where all the other keys are.
