Exploring the Human- Computer Interface
Feedback
●Any indication that either the computer is still working or has completed the request
○Ex: a cursor is replaced by a different icon to show completed or loading
○Some apps give customer feedback
○Or use a progress bar
to give an estimate on time remaining
User Interface (UI)
●The way a user interacts with system and how this responds to such interaction
○Ex: colors, contrast, buttons interaction, feedback, touch feedback, hover on
feedback
○Aka buttons u click, where on screen u swipe, click, scroll
●If files deleted bc accidentally tapped on a huge green button --> terrible UI leads to an
even worse UX (user experience)
●Xerox parc developed the Alto personal computer. It was the first computer to
demonstrate the desktop metaphor and GUI
●Apple released Macintosh and brought the a lot-style GUI to the masses
Consistent Interface
●Regardless of who makes software, icons and menus tend to be similar
●Why?
○Companies reuse the same code in each of their applications (saves time)
○Aids u in learning and using additional applications
○Certain operations are so fundamental to processing that all apps just use those
operations (easier for us)
○Consistency provides a strong sense of familiarity with a new application
Clicking and Blazing
●When we install new app, we do 2 things:
○"clicking around"
○"blazing away" is going boldly where you’ve never gone before bc you know
intuitively that you cant break anything. Its software
New Instance
●Any specific piece of info-- an image, a month, or a document-- is an instance
of its type
○Ex: term paper is an instance of the doc type of info
○July 2014 is an instance of the calendar type info
●"new" or "blank" instance is simply the structure without any properties or content
filled in
