Week 3 - Problem between human and computer By Tai Qiu Xian

Nowadays, the problem that we face in our daily life is our self with the computer. Human brain can memories things, have perception and can solve problem by its own. Computer is the combination of hardware and software which that cannot solve problem by its own and need a host to make it work. The computer need instruction from human and it need lot of instruction in specific field from human when it start works.

Before this, human computer interaction (HCI) is about efficient and effective system but today HCI is more about how design interactive systems that make people respond in certain way. If a computer want a achieves the fit is to consider about expressive interface, user frustration, persuasive technologies and anthropomorphism.

Expressive interface is all about colour, icons, sound, graphic element and animation to make interface appearing. It is to build a relationship between the user and machine and make it more natural and human like. Expressive interface can provide reassuring feedback. 

User frustration is about what user like or dislikes are share. We have to remember that “one size does not always fix all”. For example, the error message that show in our computer, the message does not show clearly that what cost of the error. To provide a good error message, we have to follow 5 of the element which is avoid using term like FATAL, INVALID, BAD, audio warning, avoid UPPER-CASE and long code numbers, messages should be precise rather than vague, provide context (sensitive help). A bad interface design will make people frustration.

Persuasion is about interactive computing systems deliberately designed to change people attitudes and behaviours (Fogg, 2003). Persuasion is to change what they do or think. For example, pop up ads, warning messages, reminders, prompts, personalised messages and recommendations.

Anthropomorphism is attributing human like qualities to any object and it is well known phenomenon. Anthropomorphism also and interpretation of what is not human or personal in terms of human or personal characteristics. For example, when human interacting with a computer with a good design, human will keep on prise the product of the design and introduce it to the people around him, this is one of the act of anthropomorphism.

In conclusion, computer is making easier for human being nowadays. It is because computer is the modern technology to let human being work easier and faster in their life. We can use this technology anytime and anywhere with just a small laptop and internet connection.We can do almost everything in the computer by just clicking a single button. For example, we can communicate face to face with each other by using video call no matter how far they are. A good computer is important to have a good interaction with human.
