Talking to computers (part 2): VUI as an error recovery system

I take a closer look at some unavoidable challenges to effective speech recognition, and I discuss why you may want to think twice before designing dialogue that is 'conversational' and 'natural'. I also offer five important questions that I think should form the basis of any VUI design kick-off meeting.

Talking to computers (part 1): Why is speech recognition so difficult?

Although the performance of today's speech recognition systems is impressive, the experience for many is still one of errors, corrections, frustration and abandoning speech in favour of alternative interaction methods. We take a closer look at speech and find out why speech recognition is so difficult.

The Principle of Least Surprise

Consistency is at the heart of good product design. But consistency is often misinterpreted as making things look or behave the same way. This ignores context and can lead to a foolish consistency. Instead of consistency, designers should adhere to the Principle of Least Surprise.

Storytelling in UX research

UX researchers are storytellers who have devised tools like personas and user journey maps to tell the story of their research. Focusing on the story, rather than the tool, is a powerful way to become more effective.

The User Researcher's Field Guide to Psychology

When planning user research studies, there are four fundamental principles from psychology that user researchers must know. These are: your users do not think like you think; your users don't have good insight into the reasons for their behaviour; the best predictor of your users' future behaviour is their past behaviour; and your users' behaviour depends on context.

A CRAP way to improve usability

Visual design is often dismissed as eye candy. In fact, we can use four key principles of visual design to create more usable interfaces. These principles are Contrast, Repetition, Alignment and Proximity.

Communicating errors

Ideally, you'll design your system to prevent errors from occurring in the first place. But no matter how simple your system, someone, somewhere, will make an error when using it. The difference between a great user experience and an awful one is what your system does next.

247 web usability guidelines

Although designing usable systems requires far more than simply applying guidelines, guidelines can still make a significant contribution to usability by promoting consistency and good practice. We use this list of guidelines in our consultancy work. For best results, remember to interpret the guideline in context — this requires a bit more thought but ensures you will get a lot more from your review. You can also download the guidelines as an Excel workbook.

Shopping basket usability: Nine tests for a usable checkout

With consumer budgets tightening, retailers need to fix every potential leak in their e-commerce site. Many sites lose customers during the series of screens that appear after the customer clicks the checkout button. We've observed hundreds of e-commerce sessions in our usability labs and the best performing sites demonstrate these 9 features.

Dragons' Den Usability

It's easy to get caught up in the promise of new technologies and lose sight of the fundamental issues that make a product successful. By listening to the questions venture capitalists pose when reviewing new products we can develop a checklist to assess the viability of a new product idea.

The A-Z of Usability

Rather than create yet another definition of usability, we decided to take a different approach and work through the alphabet, picking one word for each letter to capture the flavour of the field. So we proudly present the A-Z of usability — or usability in 26 words.
