Interaction design from multiple perspectives


Originally posted on Kanrawi's HCI Notes:

Dan Saffer introduced an interesting fact in interaction design in his book Design for interaction. The goal of interaction design is to design possible interactions for users to accomplish their goal or product or service. The interactions have to fit the time and context of the product.

Even the goal of interaction is the same, different designers might do it in many different ways depending on their experiences. One factor affecting their design is their perspective toward the design project.

Saffer suggested three perspectives.

1. Technology-centered view – designing interactions for the raw product created from software engineer or programmers in order to create good user experience.

2.Behaviorist view – designing the behavior and feedback of the product to serve the needs of the user. The focus is on the function and the feedback.

3.Social interaction design view – designing interaction between people that use the product regardless of the number of device or type of device they…

You don’t always know what you’re saying

If you think you know what you just said, think again. People can be tricked into believing they have just said something they did not, researchers report this week.

The dominant model of how speech works is that it is planned in advance — speakers begin with a conscious idea of exactly what they are going to say. But some researchers think that speech is not entirely planned, and that people know what they are saying in part through hearing themselves speak.

So cognitive scientist Andreas Lind and his colleagues at Lund University in Sweden wanted to see what would happen if someone said one word, but heard themselves saying another. “If we use auditory feedback to compare what we say with a well-specified intention, then any mismatch should be quickly detected,” he says. “But if the feedback is instead a powerful factor in a dynamic, interpretative process, then the…

Please Stop Ideating

Surely it makes sense that the more ideas we have, the better our innovation track record will be. Not true, it turns out.

Firms that hold ideation sessions − those in which a group guided by outside consultants generate ideas for new products and services − generate little additional revenue from new offerings compared to those that don’t. That was a finding of a study of consumer-package-goods companies that I led.

How could this be? Aren’t more ideas better?

Actually, coming up with an idea turns out to be relatively easy; refining a concept until it becomes an economic success is the hard part. Consider this example: The first known claim of inventing a hand-held mobile phone was made in 1906. Yet it took another 70 years of development before one that actually worked was produced.

In fact, most companies have an abundance of ideas. At one firm with a particularly dismal record…

Developing Critical Thinkers: Challenging Adults to Explore Alternative Ways of Thinking and Acting by Stephen D. Brookfield


Originally posted on


Critical thinking is defined in this book is composed of two processes: identifying and challenging assumptions, and then imagining and exploring alternatives. When I think critically, my perceived truth, or my understanding of absolute truth, changes. By questioning what I have always understood to be true, I can come to a better position, or find a better solution to a problem that I have encountered. This is the premise of the book. Not only should I learn to think differently about what I have learned, but I should learn to explore new ways of solving problems. 

Part One (chapter one through four) spends time defining the concept of critical thinking, and then presents the benefits of critical thinking. Critical thinking means that a person does not blindly accept everything they have learned. A critical thinker learns to understand what is being told to them, and then broadens their learning experience…

The Importance of Critical Thinking

“The essence of the independent mind lies not in what it thinks, but in how it thinks.” — Christopher Hitchens

Exactly what is critical thinking? According to Robert Ellis, author of The Path of Objectivity, critical thinking is reasonable, reflective thinking that is focused on deciding what to believe and what to do. Many of us do not realize our capacity for developing critical thinking. Numerous studies have shown that leaders who practice critical thinking are better able to adapt to the variables that may present within a constantly changing marketplace and competitive business environment. Critical thinking empowers employees, managers and individuals to learn from their mistakes, identify opportunities and overcome challenges both inside and outside of the workplace.

Developing our critical thinking skills requires a conscious and consistent commitment to challenge ourselves to be less judgmental, to think outside the box, to be empathic, and to change our habitual…

Cognitive Biases and Behavioural Economics

cognitive hazard


It takes the human brain three hundred to seven hundred milliseconds to identify a picture or read a word aloud from a page. We haven’t even begun to scratch the surface of the brain’s potential. However, there are many limitations to how the brain makes decisions; hiccups in our logical thinking that cause us to make unwise decisions. One such hiccup is cognitive bias. Sometimes cognitive biases help our brains process information more quickly and effectively, particularly in a crisis or tense situation where thinking faster has a direct, immediate outcome.


However, these same biases can cause us to make severe errors in judgement when we rely on them alone for processing information. A cognitive bias is a genuine failure in our thought processing – arising from miscalculations, external social influences, or personal experiences. When trading in any market, it is easy to…
