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. It is developed by Antradar Software 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 more than 4 choices at a time, their decisions ten ...

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 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 minimal in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dyslexic
Dyslexia, also known until the 1960s as word blindness, is a disorder characterized by reading below the expected level for one's age. 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 diffe ...

Ajax (programming)
Ajax (also AJAX ; short for " 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 server asynchronously (in the background) without interfering with the display and behaviour of the existing page. By decoupling the 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 concept. HTML and 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 information. The built-in XMLHttpRequest object is used to execute Ajax on webpages, all ... [...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 ... [...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 * 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 ... * Principles of attention stress References Us ...

Cognitive Load
In cognitive psychology, cognitive load refers to the amount of working memory resources used. There are three types of cognitive load: ''intrinsic'' cognitive load is the effort associated with a specific topic; ''extraneous'' cognitive load refers to the way information or tasks are presented to a learner; and ''germane'' cognitive load refers to the work put into creating a permanent store of knowledge (a schema). 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. Task-invoked pupillary response is a reliable and sensitive measurement of cognitive load that is directly related to working memory. Information may only be stored in long term memory after first being attended to, and processed by, working memory. Workin ...
