10 Heuristics for User Interface Design Visibility of system status The system should always keep users informed about what is going on, through appropriate feedback within reasonable time. (Read full article on visibility of system status.) Match between system and the real world The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. (Read full article on the match between the system and the real world.) User control and freedom Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue. Consistency and standards Users should not have to wonder whether different words, situations, or actions mean the same thing. Error prevention Even better than good error messages is a careful design which prevents a problem from occurring in the first place. (Read full article on preventing user errors.) Recognition rather than recall Help and documentation
how to be creative Accept that you’ve got the creative urge and it’s never going to go away. Make friends with it. Drink some tequila if you need to. Commit to the process. Engage! There is a gap between where you are and where you want to be. You eat the elephant one mouthful at a time. Creativity happens in the relationship between you and your medium, whether it’s the violin or writing or painting or puppetry or interpretive dance or start-ups or some combination thereof (interpretive dance puppetry, which I hear is wildly underrated). Find your tribe. Avoid toxic people. Seek constructive feedback. Master your tools. Master the difficult. Celebrate your progress, step by step by step. Embrace your limitations and constraints. If you don’t have any limitations, make some up. Develop creative rituals. Control your space. Be imperfect. Reframe failure. Go for bold heroic failures. Be solitary. Be social. Feed your head. Create conversation. Go where the conversation isn’t. Shift perspectives.
List of cognitive biases Systematic patterns of deviation from norm or rationality in judgment Cognitive biases are systematic patterns of deviation from norm and/or rationality in judgment. They are often studied in psychology, sociology and behavioral economics. Although the reality of most of these biases is confirmed by reproducible research, there are often controversies about how to classify these biases or how to explain them. Several theoretical causes are known for some cognitive biases, which provides a classification of biases by their common generative mechanism (such as noisy information-processing). Gerd Gigerenzer has criticized the framing of cognitive biases as errors in judgment, and favors interpreting them as arising from rational deviations from logical thought. Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. Belief, decision-making and behavioral Social 
Metaheuristic Compared to optimization algorithms and iterative methods, metaheuristics do not guarantee that a globally optimal solution can be found on some class of problems. Many metaheuristics implement some form of stochastic optimization, so that the solution found is dependent on the set of random variables generated. By searching over a large set of feasible solutions, metaheuristics can often find good solutions with less computational effort than can algorithms, iterative methods, or simple heuristics. As such, they are useful approaches for optimization problems. Several books and survey papers have been published on the subject. Properties and classification Different classifications of metaheuristics. These are properties that characterize most metaheuristics: There are a wide variety of metaheuristics and a number of properties along which to classify them. One approach is to characterize the type of search strategy. Applications Contributions

Brain–computer interface A brain–computer interface (BCI), sometimes called a mind-machine interface (MMI), direct neural interface (DNI), synthetic telepathy interface (STI) or brain–machine interface (BMI), is a direct communication pathway between the brain and an external device. BCIs are often directed at assisting, augmenting, or repairing human cognitive or sensory-motor functions. Research on BCIs began in the 1970s at the University of California Los Angeles (UCLA) under a grant from the National Science Foundation, followed by a contract from DARPA. The papers published after this research also mark the first appearance of the expression brain–computer interface in scientific literature. The field of BCI research and development has since focused primarily on neuroprosthetics applications that aim at restoring damaged hearing, sight and movement. History Berger's first recording device was very rudimentary. BCI versus neuroprosthetics Animal BCI research Early work 2013: M.
Heuristic Evaluation July 6, 2014 Showing users things they can recognize improves usability over needing to recall items from scratch because the extra context helps users retrieve information from memory. January 1, 1997 Discount usability engineering is our only hope. June 27, 1995 Participants in a course on usability inspection methods were surveyed 7-8 months after the course. January 1, 1995 Heuristic evaluation is a good method of identifying both major and minor problems with an interface, but the lists of usability problems found by heuristic evaluation will tend to be dominated by minor problems, which is one reason severity ratings form a useful supplement to the method. Rating usability problems according to their severity facilitates the allocation of resources to fix the most serious problems. Usability inspection is the generic name for a set of methods that are all based on having evaluators inspect a user interface. Jakob Nielsen's 10 general principles for interaction design.

Over Under Lacing This method reduces friction, making the lacing easier to tighten and loosen plus reducing wear and tear. Gap Lacing This simple variation of Criss Cross Lacing skips a crossover to create a gap in the middle of the lacing, either to bypass a sensitive area on the instep or to increase ankle flexibility. Straight European Lacing This traditional method of Straight Lacing appears to be more common in Europe. Straight Bar Lacing Hiking / Biking Lacing Quick Tight Lacing Ukrainian Lacing- New!

Weird Encyclopedia - a Quick & Dirty Guide to All Things Strange SMART HEURISTICS What interests me is the question of how humans learn to live with uncertainty. Before the scientific revolution determinism was a strong ideal. Religion brought about a denial of uncertainty, and many people knew that their kin or their race was exactly the one that God had favored. They also thought they were entitled to get rid of competing ideas and the people that propagated them. How does a society change from this condition into one in which we understand that there is this fundamental uncertainty? How do we avoid the illusion of certainty to produce the understanding that everything, whether it be a medical test or deciding on the best cure for a particular kind of cancer, has a fundamental element of uncertainty? Introduction "Isn’t more information always better?" Gigerenzer provides an alternative to the view of the mind as a cognitive optimizer, and also to its mirror image, the mind as a cognitive miser.
