The principles and processes of user interface design
How users and their tasks are identified
How to balance the concepts of doable, usable and likable in a health care settingLearning Objectives
The communication between human and computer
An interface enables a user to interact with a system to perform a task. For example:
website navigation (hyperlinks, search tools, etc.) enables a user to find content
a shopping cart/basket system enables goods to be ordered
the formatting palette in Microsoft Word enables a user to change text colour, size, font, etc.Some Definitions to Start With…
A GUI allows a user to interact with a computer without entering code
With the combination of an input device (such as a mouse or stylus) and visual representations of the workspace and tasks, the user is able to interact with the computer in a manner similar to the physical manipulations available in the real world.Some Definitions to Start With…
bitmap display (graphic image)
Combining these elements allowed a user to interact with the computer without translating the user’s request into machine code.
visual/graphic: text (labels); shape, colour and size; spatial cues such as beveling and shadows to indicate ‘click-ability’; icons; change when moused-over; etc.
aural: speech, beeps, clicks, etc.
An effective interface combines the available, contextually-appropriate sensory cues to:
inform users of the task the interface can be used to complete
provide feedback (in response to interaction) to confirm task status (often referred to as closure).
Does the user perceive that clicking on that object is a meaningful, useful action, with a known outcome? (Where ‘object’ is an interface element, such as a button, checkbox or hyperlink.)
The designer cares more about what actions the user perceives to be possible than what is true.
Usability is a measure of the quality of a person’s experience in interacting with content or services.
How fast can a user who has never seen the user interface before learn it sufficiently well to accomplish basic tasks?
Efficiency of use
Once an experienced user has learned to use the system, how fast can he or she accomplish tasks?
If a user has used the system before, can he or she remember enough to use it effectively the next time or does the user have to start over again learning everything?
How often do users make errors while using the system, how serious are these errors, and how do users recover from these errors?
How much does the user like using the system

No difference in regards to gender
Nurses younger than 30 had significantly more positive score than older nurses
Nurses with a bachelor’s degree had a more positive score
Nurses with computer science education had a more positive score
Nurses who attended classes in medical informatics during their formal education had a significantly more positive score
Nurses with previous computer training had significantly more positive score with users who did not use computers scoring less than nurses using computers at home
Nurses using computers for any purpose (work, education, pleasure, communication) also related to a higher attitude towards computers
the situation in which an interface is to be used
the task(s) the user will complete using the interface
how a task is broken down into meaningful stages and sequences
sensory cues and interaction models likely to be known by the user
