Principles Of Attention Stress
The principles of attention stress is a user interface design theory to measure the amount of attention that is required to perform certain tasks in a web application. Antradar Software develops it in an attempt to benchmark the ease of use of open source CMS products and to monitor the trend of UI designs. The attention stress theory is based on many psychological observations, of which the two most important ones are: * attention shift * selection threshold Attention shift addresses the issue of "getting lost", or the experience of a "broken flow". It is usually measured by the number of page refreshes or the amount of hand–eye coordination required to complete a task. According to attention shift, new pages cause more stress than pop-ups, and pop-ups are more "expensive" than things like inline-editing. Selection threshold deals with the matter of "being overwhelmed". It is observed that when the users are presented with more than 4 choices at a time, their decisions tend ...

User Interface
In the industrial design field of human–computer interaction, a user interface (UI) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls and Unit operation, process controls. The design considerations applicable when creating user interfaces are related to, or involve such disciplines as, ergonomics and psychology. Generally, the goal of user interface design is to produce a user interface that makes it easy, efficient, and enjoyable (user-friendly) to operate a machine in the way which produces the desired result (i.e. maximum usability). This generally means that the operator needs to provide mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dyslexic
Dyslexia (), previously known as word blindness, is a learning disability that affects either reading or writing. Different people are affected to different degrees. Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing words when reading aloud and understanding what one reads. Often these difficulties are first noticed at school. The difficulties are involuntary, and people with this disorder have a normal desire to learn. People with dyslexia have higher rates of attention deficit hyperactivity disorder (ADHD), developmental language disorders, and difficulties with numbers. Dyslexia is believed to be caused by the interaction of genetic and environmental factors. Some cases run in families. Dyslexia that develops due to a traumatic brain injury, stroke, or dementia is sometimes called "acquired dyslexia" or alexia. The underlying mechanisms of dyslexia result from differences within language ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ajax (programming)
Ajax (also AJAX ; short for "asynchronous I/O, asynchronous JavaScript and XML") is a set of web development techniques that uses various web technologies on the client-side to create asynchronous web applications. With Ajax, web applications can send and retrieve data from a Web server, server asynchronously (in the background) without interfering with the display and behaviour of the existing page. By decoupling the data exchange, data interchange layer from the presentation layer, Ajax allows web pages and, by extension, web applications, to change content dynamically without the need to reload the entire page. In practice, modern implementations commonly utilize JSON instead of XML. Ajax is not a technology, but rather a programming pattern. Hypertext Markup Language, HTML and Cascading Style Sheets, CSS can be used in combination to mark up and style information. The webpage can be modified by JavaScript to dynamically display (and allow the user to interact with) the new i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attention Management
Attention management refers to models and tools for supporting the management of attention at the individual or at the collective level (cf. attention economy), and at the short-term (quasi real time) or at a longer term (over periods of weeks or months). The ability to control distractions and stay focused is essential to produce higher quality results. A research conducted by Stanford shows that single-tasking is more effective and productive than multi-tasking. Different studies have been conducted in using Information and Communications Technology (ICT) for supporting attention, and in particular, models have been elaborated for supporting attention. Background The scarcity of attention is the underlying assumption for attention management; the researcher Herbert A. Simon pointed out that when there is a vast availability of information, attention becomes the more scarce resource as human beings cannot digest all the information. Fundamentally, attention is limited by the pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attentive User Interface
Attentive user interfaces (AUI) are user interfaces that manage the user's attention. For instance, an AUI can manage notifications, deciding when to interrupt the user, the kind of warnings, and the level of detail of the messages presented to the user. Attentive user interfaces, by generating only the relevant information, can in particular be used to display information in a way that increase the effectiveness of the interaction. According to Roel Vertegaal, there are four main types of attentive user interfaces: * Visual attention * Turn management * Interruption decision interfaces * Visual detail management interfaces See also * Adaptive hypermedia Adaptive hypermedia (AH) uses hypermedia which is adaptive according to a '' user model''. In contrast to regular hypermedia, where all users are offered the same set of hyperlinks, adaptive hypermedia (AH) tailors what the user is offered based on ... * Attention management * Principles of attention stress References [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Load
In cognitive psychology, cognitive load is the effort being used in the working memory. According to work conducted in the field of instructional design and pedagogy, broadly, there are three types of cognitive load: * ''Intrinsic'' cognitive load is the effort associated with a specific topic. * ''Germane cognitive load refers to the work put into creating a permanent store of knowledge (a schema).'' * ''Extraneous'' cognitive load refers to the way information or tasks are presented to a learner. However, over the years, the additivity of these types of cognitive load has been investigated and questioned. Now it is believed that they circularly influence each other. Cognitive load theory was developed in the late 1980s out of a study of problem solving by John Sweller. Sweller argued that instructional design can be used to reduce cognitive load in learners. Much later, other researchers developed a way to measure perceived mental effort which is indicative of cognitive load. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ego Depletion
Ego depletion is the idea that self-control or willpower draws upon conscious mental resources that can be taxed to exhaustion when in constant use with no reprieve (with the word "ego" used in the psychoanalytic sense rather than the colloquial sense). When the energy for mental activity is low, self-control is typically impaired, which would be considered a state of ego depletion. In particular, experiencing a state of ego depletion impairs the ability to control oneself later on. A depleting task requiring self-control can have a hindering effect on a subsequent self-control task, even if the tasks are seemingly unrelated. Self-control plays a valuable role in the functioning of the self on both individualistic and interpersonal levels. Ego depletion is therefore a critical topic in experimental psychology, specifically social psychology, because it is a mechanism that contributes to the understanding of the processes of human self-control. There have both been studies to supp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fatigue
Fatigue is a state of tiredness (which is not sleepiness), exhaustion or loss of energy. It is a signs and symptoms, symptom of any of various diseases; it is not a disease in itself. Fatigue (in the medical sense) is sometimes associated with medical conditions including autoimmune disease, organ failure, chronic pain conditions, mood disorders, heart disease, infectious diseases, and post-infectious-disease states. However, fatigue is complex and in up to a third of primary care cases no medical or psychiatric diagnosis is found. Fatigue (in the general usage sense of normal tiredness) often follows prolonged physical or mental activity. Physical fatigue results from muscle fatigue brought about by intense physical activity. Mental fatigue results from prolonged periods of Cognition, cognitive activity which impairs cognitive ability, can manifest as sleepiness, lethargy, or directed attention fatigue, and can also impair physical performance.

Keyboard Warrior
Keyboard warrior, sometimes keyboard cowboy, is a term that refers to a person who makes abusive or aggressive posts on the internet, typically one who conceals their true identity. History The term was first used in the 1960s, with the earliest known evidence of it appearing in the '' Daily Gleaner'' in Fredericton, Canada in 1968. This term used in the early to mid-2000s to refer to online gamers, often viewed through a particular stereotype: "The mythic keyboard warrior," the ''International Herald Tribune'' reported in 2006, "is usually portrayed as a gangly teenage boy hypnotized in the moonlight before a computer screen flickering with assorted night elves, dwarves and the forsaken undead." The term came to be associated with online activism, including by those using the internet as a tool of resistance in more repressive environments. In 2025, Filipino senator Francis Tolentino revealed that the Philippine-based public relations firm InfinitUs Marketing Solutions, Inc. h ...
