Quick Answer: What Is Robustness In HCI?

What are the five principles that affect Learnability?

5 Essential Principles of Learnability to Improve Your WebsiteSimplicity.

Make user interfaces simple.


This principle is based on the idea that user interfaces are at their best when there are no surprises for the user.


This principle is similar to simplicity and familiarity.

Controls That People Expect.

Provide Context and Feedback..

What are the HCI principles?

Shneiderman’s Eight Golden RulesStrive for Consistency.Cater to Universal Usability.Offer Informative feedback.Design Dialogs to yield closure.Prevent Errors.Permit easy reversal of actions.Support internal locus of control.Reduce short term memory load.

What does ruggedness mean?

ruggedness – the property of being big and strong. huskiness, toughness. strength – the property of being physically or mentally strong; “fatigue sapped his strength” 2. ruggedness – the quality of being topologically uneven; “the ruggedness of the mountains”

What is predictability in HCI?

Predictability of an interactive system means that the user’s knowledge of the interaction history is sufficient to determine the result of his future interaction with it. … There are many degrees to which predictability can be satisfied.

What is recoverability principle?

Recoverability is the ability to reach a desired goal after recognition of some error in previous interaction. … Backward error recovery is an attempt to undo the effects of previous interaction in order to return to a prior state before proceeding.

What is familiarity in HCI?

Familiarity. The familiarity principle is concerned with the ability of an interactive system to allow a user to map prior experiences, either real world or gained from interaction with other systems, onto the features of a new system.

What is Synthesizability of the system?

• Synthesizability. – ability of the user to assess the effect of. past operations on the current state.

What is the difference between ruggedness and robustness?

Along the similar lines it has been suggested that ruggedness should be used as a parameter evaluating constancy of the results when external factors such as analyst, laboratory, instrument, reagents and days are varied and robustness should be used as a parameter characterizing the stability of the method with respect …

What is consistency in HCI?

Consistency in human-computer interaction tasks is usually considered in a trans- fer paradigm in which the higher the similarity between two tasks, the higher the transfer and consistency. … Two experiments tested the predictions of the quantitative analyses of consistency for alternating tasks.

Which is the following specific principle supports to robustness?

Postel’s Law, also known as the robustness principle, states: Be conservative in what you do, be liberal in what you accept from others. Jon Postel wrote this in an early version of the TCP specification in 1980, and it has since been referred to as Postel’s Law.

What does tedious mean?

: tiresome because of length or dullness : boring a tedious public ceremony.

What does robustness mean?

Robustness is the property of being strong and healthy in constitution. … In the same line robustness can be defined as “the ability of a system to resist change without adapting its initial stable configuration”.

How do you calculate robustness?

Robustness is generally calculated for a given decision alternative, xi, across a given set of future scenarios S = {s1, s2, …, sn} using a particular performance metric f(·).

What are the 8 golden rules of interface design?
