Study & Write T9 (A good and a bad ergonomics design examples)
In this post I would like to provide two examples of designs: one with bad ergonomics and one with good ergonomics.
Bad design: Keyboards
Many PC users are used to keyboard shortcuts. It makes their life much easier, for example, CTRL+C and CTRL+V is probably known by everybody. Instead of clicking right mouse button, repositioning your pointer and clicking "copy", you can just use CTRL+C shortcut. We got used to the fact that CTRL is located on the left bottom of the keyboard. This proved to be quite convenient and we can always find the key without looking at it.
Another handy key is a Fn (function) key. It is undoubtedly useful in many situations, but it is not used as regularly as CTRL. It is usually placed to the right of the control key, as seen in the picture below.
However, some manufacturers decided to swap Fn and CTRL key and place Fn at the bottom left of the keyboard for some reason. In my opinion, it is a horrible design solution, since we are used to the fact that CTRL is always located on the bottom left part of a keyboard. Fn in the lower left corner is usually found on laptops (especially in Lenovos), though luckily, it is usually possible to make Fn key function as a CTRL key in BIOS settings.
Good design: Touch ID technology
With Touch ID technology it is possible to use your fingerprint as a password. And in my opinion, it is a great and convenient technology for keeping your data secure. Your fingerprint is completely unique, which means that only you can unlock the phone and unlocking your phone with the fingerprint is much faster than typing in the password. Also, the fact that the sensor is located on the front panel (home button or on screen) makes it even more better. However, there are some exceptions. On some phones, the sensor is located on the back panel, so you have to stretch your pointing finger high up. In every other aspect, it is great. I would even say that it is sometimes more convenient than Face ID, since Face ID requires picking up your phone and looking at the camera, but with Touch ID it is simpler to fast-check your messages. You can leave your phone lying on the table and quickly scan your fingerprint, check new notifications and lock the phone back.
