Week 3 | User Based Interaction

Problems with HCI

There are a lot of problems when we are using a computer. One of the example could be when we are about to open a file and an error suddenly pops up. Showing the errors with some error codes does not solve the problem. This makes the user getting irritated and frustrated when using an interface. To solve this problem developers should actually link or tell us on how we can fix/prevent this error. Doing so will mostly make it easier for users to know and understand what they have done wrong. Telling us an error, doesn't really help. Giving us solutions to solve/fix the error is a good way to satisfy the user.

What to avoid in an error message :

1. Avoid using UPPERCASE letters.

2. Avoid using sound warning

3. Lastly, avoid using the word INVALID, FATAL, and BAD.

What should be included in an error message :

1. Solutions to solve the problem.

2. Message should not be vague and must be precise.

3. Message which tells the user that it is the computer's fault helps the user fell happy.

4. Provide context sensitive help

Affective User Interface

1. Simple - Simple is of course the best way to make an affective interface design. Simple design are easy to remember and easy to learn. Simple is pleasing to our eyes and makes our eyes relax while doing our work.

2. User-Controlled - The user, not the computer, initiates and controls all actions.

3. Clear - A clear interface makes information obvious and makes a user friendly interface.

4. Forgiving - Human makes mistakes, the interface should provide solutions/answers to the problem that the user has.

5. Consistent - A consistent interface allows users to apply previously learned knowledge to new tasks. Effective applications are both consistent within themselves and consistent with one another.

6. Direct - Users must see the visible cause-and-effect relationship between the actions they take and the objects on the screen. This allows users to feel that they are in charge of the computer's activities.
