Introduction to Human Computer Interaction

The bottom-line benefits of usability to development organizations include:	[Greater] profits due to more competitive products/services [Decreased] overall development and maintenance costs [Decreased] customer support costs [More] follow-on business due to satisfied customers
HCI tries to provide us with allunderstanding of the computer and the person using it, so as to make the interaction between them ___________ and ___________.	effective, enjoyable
software system is one that supports the effective and efficient completino of tasks in a given work context.	usable
Sense Cam is a wearable tool that takes photographs intermittently when worn without any user interference	FALSE
Perception allows us to focus on information that is relevant to what we are doing and it involves an audio and/or visual senses.	FALSE
One of HCI's goals is to create specific capabilities and constraints for the software and/or hardware and platform chosen for the product	TRUE
HCI is about understanding and creating software and other technology that people: (select all correct answers)	will want to use, will be able to use, will find effective whenused
Humans have a restricted capacity for processing information	TRUE
HCI is about understanding and creating software and other technology that people will want to use, will be able to use, and will find effective when used.	TRUE
HCI encompasses three major parts within the framework, ____________, _______________ and _________________.	human, computer, interaction
The benefits of more usable software system to business users include:	increased productivity, decreased user training time and cost, decreased user errors
Visibility is what operations and manipulation can be performed on a given entity	FALSE
Social processes such as turn-taking, conventions etc. help us to work together and organize our activities	TRUE
HCI concerns more on computing systems for human use.	FALSE
HCI is about understanding and developing software and other technology that will allow people to use, be able to use, and be successful when used.	TRUE
When humans communicate with _____________, they bring to the encounter a lifetime of	computer
What is the fundamental insight that underlies the evaluation process of "cognitive walk through?"	The idea that users earn by exploring an interface
Individual differences (need for structure vs. flexibility) and work situations (overloaded vs. bored) would mean that a one-size-fits-all solution is neither feasible nor prudent as we strive for optimum workplace environment and human efficiency.	TRUE
HCI is the study of how people use computer systems to certain tasks.	FALSE
Keeping abreast of what others do and letting others know what you do are irrelevant aspects of collaborative work and socialization	FALSE
A software engineer trained in the development of user interfaces would have gained experience, learned about approaches and techniques and gained an understanding of its weaknesses.	TRUE
HCI is the study and the practice of _______.	usability
Developers must attempt to ______________________ in order to produce computer systems with good usability.	achieve efficient, effective and safe interactionDecreased user training time and cost, Decreased user errors, Increased accuracy of data input and data interpretation, Decreased need for ongoing technical support
