What you think people are going to see on your webpage may not be what they do see.It might depend on their background knowledge,familiarity with what they are looking at,and expectations.
You might be able to persuade people to see thing in a certain way,depending on how they are presented.
If you want users to concentrate on a certain part of the screen,don’t put animation or blinking elements in their peripheral vision
get the gist of:获取要义
Use pattens as much as possible since people will automatically be looking for them.Use grouping and white space to create patterns.
People recognize and react to faces on Web pages faster than anything else on the page(at least by those who are not autistic).
fusiform face area (FFA):纺锤体(脸部区域)
People recoginze a drawing or object faster and remember it better if it’s shown in the canonical perspective.
Put the most important information(or things you want to people focus on)in the top third of the screen or in the middle.
If you want people to take action on an object,thether in real life or on a computer screen,you need to make sure that they can easily perceive,figure out,and interpret what the object is and what they can and should do with it.
Avoid providing incorrect affordance cues.
Rethink hover cues if you are designing for a device that uses touch rather than a pointing device.
cues:these cues are called _affordances_
If you are paying attention to one thing, and you don’t expect changes to appear,then you can easily miss changes.
If you want to be sure that people notice a change in their visual fields,add additional visual cues(such as blinking)or auditory cues(such as beap).
Sometimes changing the spacing is sufficient,and you will be reducing the visual noise of the page.
Avoid red,green and blue(around them).
saccade and fixation:眼睛飞快地扫视和定影
Reading is all about anticipating the next word.
Don’t assume that people will remember specific info in what they read.
Provide a meaningful title or headline.
The Flesch-Kincaid Readability Formula:206.835 - 1.015(total words/total sentences) - 84.6(total syllables/total words)
Unusual or overly decorative fonts can interfere with pattern recognition and slow down reading.
Large x-heights can make a font look larger.
Black text on a white background is easiest to read.
Use a longer line length(100 characters per line) if reading is an issue,vesvus.
Stress impairs working memory.
Working memory is sensitive to interference – too much sensory input will prevent them from focusing attention.
How do people move things from working memory into long-term memory?There are basically two ways:repeat it a lot,or connect it to sth they already know.
The head is a schema ,so is eye.People use schema (plural for schema) to store information in long-tern memory and to retrieve it.
If people already have a shcema that relates to information that you are providing,make sure you point out what that schema is.It will be easier for them to learn and remember the information if they can plug it into an existing schema.
Recognition makes use of context and context helps you remember.
Information in the middle of a presentation will be the least likely to be remembered.
grain of salt:有保留的
The later experience has changed your memory
Design with forgetting in mind.If some information is really important,don’t rely on people to remember it.Provide it for them in your design,or have a way for them to easily look it up.
If you know that someone had a dramatic or traumatic experience,you need to understand two things:1.They will be convinced that what they remember is true and 2.It’s not exactly true!
《Don't make me think》
If you have to make a trade-off on clicks versus thinking,use more clicks and less thinking.
All “loads” are not equal:cognitive,visual,motor.
When you design a product, remember that making people think or remember (cognitive load) requires the most mental resources.
mind wander != daydream
People like Web surfing because it grabs onto mind wandering (hyper links).
Don’t speed a lot of time trying to change someone’s ingrained(根深蒂固的) beliefs.
One of the best purposes of training on a new pruduct is to adjust the audiences mental model to fit to the conceptual model of the product.
The secret to designing an intuitive user experience is making sure that the conceptual model of your product matches as much as possible,the mental models of your audience.If you get it right,you will have created a positive and useful experience.
If you have a brand new product that you know will not match anyone’s mental model, you will need to provide training to prepare people to create a new mental model.
Don’t just tell people what to do ,show them.
People like to put things into categories.
The more mental processing you do,the more time you think has elapsed.
Always provide progress indicates so people know how much time sth is going to take.
Therapeutic A-ha Moment
Deliberate & Cognitive Creativity
Pay focused attention
Make connections ammong bits of information you’ve stored in other parts of your brain.
Deliberate & Emotional Creativity
Spontaneous & Cognitive Creativiy
Spontaneous & Emotional Creativity
Remember that your own creative process for design follows these same rules.Allow yourself time to work on a creative design solution and when you are stuck,sleep on it.
If you’re trying to design for,or induce,a flow state (for example,you are a game designer)
1.Give people contol over their actions during the activity.
2.Break up the difficulty into stages to feel that the current goal is challenging,yet achievable.
3.Give constant feedback.
Be careful of overgeneralizing.
