Useful information clutters designs

Here's a great Dilbert on how narrow minded graphic designers tend to sacrifice the communicative and functional aspects of design on the alter of eye candy.

Top usability findings 2010

Jeff Sauro has complied a list of top 10 research-based usability findings of the year 2010. Here's a sample of the five most interesting:

- Users are able to self-report around half of the problems that can be found during moderated usability tests

- Usability accounts for at least 30% of customer loyalty

- Ratings of website usability after only 5 seconds are the same as those after 10 minutes.

- 10% of paid participants in remote user research will cheat

- Usability problems are almost 10-times more common on business applications than on websites

7 persuasion techniques

In this article, David Travis shows how to exploit seven persuasion techniques in web design:

- Reciprocation. By doing people a small favour, such as a giving them free chapter from a book, they will feel obligated to return the favour and buy the book.

- Commitment. By making people make a public commitment to something (e.g. "Like" a product) they will feel more inclined to support it

- Social Proof. By indicating that something is popular more people will want it.

- Authority. People are more likely to take action if a message comes from a credible and authoritative source.

- Scarcity. By indicating that something is in short supply or available only for a limited time, people are more likely to want it.

- Framing. By overpricing some products, the other alternatives will seem cheaper.

- Salience. People are more likely to pay attention to elements in your user interface that are novel and relevant to their tasks.

How to do A/B and multivariate testing

A/B and multivariate testing are techniques used to tests how different design variations influence peoples' behavior on a website.

In this article, Paras Chopra explains how to set up such tests by first forming hypotheses about what might be wrong with a design and then testing possible solutions on the website to see how each of them perform.

In the article, Paras shows how some minor adjustments of a software download page increased its download rate by 60%.

UXPin - a paper prototyping kit

If you want to make your paper prototyping a little easier, you might consider investing in a UXPin Portable Kit. It comes with a browser notepad and pads of restickable interface elements, such as buttons, text fields, drop down lists and check boxes, nicely packed in a hard-cover.
