week 3 post 3: reflection

     In this week's lesson, I learned the real complexity of Human computer interaction. Because when they design the interface successfully, we do not tend to notice because we do not have any issues with completing our tasks. That is why understanding the invisible interfaces is very important in Human computer interaction. Application of an effective feedback cycle from week two, actually connects with direct manipulation and invisible interfaces, because the interfaces are most effective when the user has a sense or understands that they are directly manipulating and interacting with their task. I also learned that interfaces become invisible because we learn to use this application. So even if there is a new change or application on a device, once we learn to use it, we eventually forget it is there because the interface has become invisible because it is something we are accustomed to.

    I also learned that there are 5 key tips in designing an invisible interface. first, affordance. affordance is the visual design of the interface that is used how it's supposed to, an example of this would be pressing buttons. I learned that using affordance makes interfaces simpler and more usable. the second tip is knowing the users and who you are trying to design for. Third, differentiate between users, this provides multiple ways to complete a task which is friendly for any user. fourth, letting your interface teach the user. and lasty, firth, talking to your user, if they talk about or bring up the interface that means it is visible which is a sign that your interface is getting in the way of the user's goal or task in mind. All these steps will help maximize the efficiency and usability of your design. a question i have is how do you collect data from users to find out the most efficient designs? How does Human Compter interaction research work?
