Does the assessment process distort the results?
What is facial coding?
A __ software system is one that supports the effective and efficient completino of tasks in a given work context.
You cannot use inspections to test specifications, mockups, functional prototypes, or systems.

For user testing on your low fidelity prototypes, you will:
A search engine depends on _______to find information on the web.
Usually a high authority approves the design of the informed consent form, the assessment procedure, data processing and data storage methods
The program will also keep users updated in a reasonable time about what's happening through correct feedback.
Usability research is based on indicators of success, e.g. How long and how many errors are made while performing a series of predefined tasks. Indirect observation (video and keystroke logging), questionnaires regarding user satisfaction, and interviews are also collected.
What is physiological reactions?
What is reflective design?
Perception allows us to focus on information that is relevant to what we are doing and it involves an audio and/or visual senses.
Can the system measure what they are supposed to calculate?
Which of the following is design's golden rule?
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.
Field studies involving the implementation in natural settings of prototypes or innovations can also be referred to as 'in the wild.'
__ overall development and maintenance costs
Which of the following is a concept indicating that we understand human attention?
It is easier to incorporate user feedback during low-fidelity prototyping compared to high-fidelity prototyping
It is the design of the interaction between users and products.
What are the elements of the Gulf of Execution?
What is Anthromorphism?
There are three broad categories of user. This category of users know well how to perform the tasks they need to perform frequently.
Which of the following is the principles of HCI?
What are expressive interfaces?
Evaluations may be carried out in controlled settings such as labs, less controlled field settings, or where no users are present.
Several systems and technologies were developed to support telepresence and co-presence
__ follow-on business due to satisfied customers
Human-Computer Interaction (HCI) is a multidisciplinary area of study focused on computer technology design and, in particular, the interaction between ______________________.
Does the process yield the same results on different occasions?
Visibility is what operations and manipulation can be performed on a given entity
Fidelity can be in terms of one or some or all of the following areas:
What is emotional interaction?
Developers must attempt to ______________________ in order to produce computer systems with good usability.
HCI encompasses three major parts within the framework, ____________, _______________ and _________________.
A Prototype is

Speech-recognition systems allow users to communicate using spoken commands
You want to test the intuitiveness of the functionality of the application. For this task, you will use:
When is an interface annoying?

Expert is told of the assumptions regarding consumer population, sense of usage, task specifics in heuristic evaluation.
These are set of options that appear on screen.
Which one of these would NOT be found in a good HCI?
Error messages should be expressed in plain language (no codes), the problem should be specified precisely and a solution suggested constructively.
Remote testing systems which are inexpensive are more compact than usability laboratories. Many do have handheld eye-tracking apps and other tools.

Interaction design concerned with ___________
Low-fidelity prototyping requires more precision than high-fidelity prototyping because that is when the major structure of the application is being designed
Usability testing and trials require the assessor to have a high degree of control over what is being tested, while evaluators usually exert little or no control on participants in field studies.

The prototyping phase follows after which of the following steps?
Usability testing is carried out in regulated labs or temporary laboratories.
User-free settings are intended to predict, analyze & model aspects of device analytics.
