For the previous week, HCI is introduced to us and for this week, we continue discuss about HCI but focus more on the problem of HCI. The most common problem occurs between the interaction of human and computer is the output of the machine is not always what the user wants. Computer use input and output devices to process information that are upload into it while human process information through language, communication, and interaction. Why is it important to achieve FIT?
Expressive Interfaces
• Colour, icons, sounds, graphical elements and animations are used to make the ‘look and feel’ of an interface appealing
– Conveys an emotional state
• In turn this can affect the usability of an interface
– People are prepared to put up with certain aspects of an interface (e.g. slow download rate) if the end result is very appealing and aesthetic.
User frustration
Causes:
•When an application doesn’t work properly or crashes
•When a system doesn’t do what the user wants it to do
•When a user’s expectations are not met
•When a system does not provide sufficient information to enable the user to know what to do
•When error messages pop up that are vague, obtuse or condemning
•When the appearance of an interface is garish, noisy, gimmicky or patronizing
Anthropomorphism
• Attributing human-like qualities to inanimate objects
- Cars and computers.
• Well known phenomenon in advertising
– Dancing butter, drinks, breakfast cereals
• Much exploited in human-computer interaction
– Make user experience more enjoyable, more motivating, make people feel at ease, reduce anxiety
Criticism of Anthropomorphism
•Deceptive, make people feel anxious, inferior or stupid.
•People tend not to like screen characters that point out mistakes.
•Many prefer the more impersonal.
•Studies have shown that personalized feedback is considered to be less honest + makes users feel less responsible for their actions.
What will human react when they see this? What will they feel? Definitely, human will be unhappy and will start stressed out with it. It might take times and sometimes still could not solve it. With the technology we have nowadays, people keep trying their best to create computers which are user friendly. In my opinion, humans are the most unpredictable part of any system and therefore the most difficult to model for HCI design. No matter how good the design is in the future, it will still end with human own preferences.
