Week 3 | HCI - The problems

In this week, we learnt about the problems that might occurs in HCI.
As we know accessibility and usability are the main components in HCI. Without it human will have  problems while interacting with computer.The example of problems that human might face are :

 - dont know how to solve and react to an error when it appear
 - capabilities and limitations in seeking to ensure that tasks, equipment, information    that can suit human and computer
 - miscommunication and cannot understand syntax,programming language and coding

When it come to a problems like this, human must now realize that some of the error massage need to be reform to give better understanding and improve usability at the same time.

These are the shneiderman's 5 guidelines for error messages that need to be considered:-

1) avoid using terms like FATAL, INVALID, BAD
2) audio warnings
3) avoid UPPERCASE and long code numbers
4) message should be precise rather than vague
5) provide context - sensitive help

On the other hand, we also need to know about Anthropomism which are conceptual or representation of human attribute to a non-human.As we know computer can never be compared to human, but in this situation computer need to perform task and react more appropiately towards human to fulfill the need of user usability. For example, computer now are more friendly as they can give better feedback and reaction such as "Hello and have a nice day" rather than just show some static massage.It was a succesful idea as it will create a good interaction between human and computer and make user feel comfortable.


As conclusion,
A good system interactivity,well design of interfaces and appropiate respond will provide a user-friendly interaction between human and computer because it make user happy and comfortable of using it.
