(For example: Visibility: A TV remote is showing all the operations it can perform with a better sectioning in a good arrangement. Each function can be seen on the remote, but all the functions which are needed and which are needed rarely, it makes your deign a bit complex and difficult for a naïve user to understand.)

Q. 1 Solution Idea
Devices Visibility Consistency Constraints Affordance Keyboard Keyboard design is a good design all the Alphabet and numeric are in different section also the special function key are arranged in top of the keyboard, specially delete button is very good deployed at right top, which cannot be accidentally pressed during any typing. Keyboard has strict constraint i.e if we want to used special character which are on numeric buttons these cannot be activated without pressing the shift button. Or some button on keyboard especially on laptop is only work with pressing “fn” key. Atm machine ATM has good visibility because it have a limited amount of button on his left and right side and only some limited amount of processing screen. ATM has low consistence because there is no similar function to perform. ATM machine have strongly constraint because without the limited amount of action the individual can nothing to do. ATM Machine have no good affordance because naive users have facing a lot of difficulty while using the ATM. Digital watch Digital watch have no good visibility because its screen is not visible in full sun light and in darken area. It is not consistence device because every button has its function, we cannot perform similar task with different button or method. Digital watch has less affordance because its button have no label, so the naïve user can not configure the time or date. Digital camera It has consistence function because every time we press the button the same work will be done against mentioned button. Good constraint because a person cannot capture video except listed format. Also we cannot change function or setting of camera. Less affordance because the new user can used Digital camera with facing some difficulties.
