The cognitive walkthrough method is a usability inspection method used to identify usability issues in a piece of software or web site, focusing on how easy it is for new users to accomplish tasks with the system.

HCISec is the study of interaction between humans and computers, or HCI , specifically as it pertains to information security . Its aim, in plain terms, is to improve the usability of security features in end user applications. Unlike HCI, which has roots in the early days of Xerox PARC during the 1970s, HCISec is a nascent field of study by comparison. Not surprisingly, interest in this topic tracks with that of Internet security , which has become an area of broad public concern only in very recent years. Historically, security features exhibit poor usability for reasons that include they were added in casual afterthought they were hastily patched in to address newly discovered security bug s they address very complex use case s without the benefit of a Wizard software software wizard their interface designers lacked understanding of related security concepts their interface designers were not usability experts often meaning they were the application developers themselves See also Human computer interaction Further reading http www.simson.net thesis Design Principles and Patterns for Computer Systems That Are Simultaneously Secure and Usable , by Simson Garfinkel External links http gaudior.net alma biblio.html HCISec Bibliography http tech.groups.yahoo.com group hcisec HCISec Yahoo Group http www.usablesecurity.com Usable Security Blog Category Human communication Category Human computer interaction Category Computer security ... more details

Wikify date September 2010 NFR Non functional requirement Non Functional Requirements is a framework on Goal Modelling . The analysis begins with softgoals that represent NFR which stakeholders agree upon. Softgoals are goals that are hard to express, but tend to be global qualities of a software system. These could be usability, performance, security and flexibility in a given system. These softgoals are then usually decomposed and refined to uncover a tree structure of goals and subgoals for e.g. the flexibility softgoal. Once uncovering tree structures, one is bound to find interfering softgoals in different trees, e.g. security goals generally interferes with usability. These softgoal trees now form a softgoal graph structure. The final step in this analysis is to pick some particular leaf softgoals, so that all the root softgoals are satisfied.

notability date November 2011 unreferenced date December 2011 Human machine interaction HMI is the interaction between machines and the persons who operate them. An old fashioned historic term is man machine interaction MMI . Related terms An interactive system in contrast with automated systems is a system for which human control or human supervision is required for its operation. The part of the machine used to interact with the human operator is called Human machine interface . In complex systems, the human machine interface is typically computerized. The terms Human computer interaction and Human computer interface refer to these systems. A primary goal in the design and development of interactive systems is to maximize the user s productivity and safety and satisfaction. The set of procedures used to get this goal is called usability assurance . The goals of usability assurance are to maximize the system utility usefulness and to minimize the operational risks . The engineering of the human machine interfaces is by considering ergonomics human factors . The corresponding disciplines are human factors engineering HFE and usability engineering UE , which is part of systems engineering . The knowledge about human factors is gained through behavioral sciences such as linguistics , social sciences and cognitive psychology . Theories of human machine interaction are based on communication theory , in which the human operator is regarded as a sub system, with special values of performance properties response time, error rates, learning rate, memory capacity, retention rates, vigilance, etc. . Theories about evaluating success and failure of the interaction apply knowledge about use error s, risk assessment and resilience engineering .
