Human Factors symposium

Leave a comment

I attended a Human Factors symposium at the University of Toronto. It was organized by the HFIG (Human Factors Interest Group) and titled as Celebration of Applied Human Factors Research, in Honour of Prof. John W. Senders’ 90th Birthday.

At the symposium, I noticed an interesting connection between decision-making and Human Factors. Research in decision-making studies decision biases and provides prescriptions to eliminate or mitigate them. Similarly, HF researchers study errors from the real-life examples and suggest practical recommendations to overcome those errors.

For instance, John Senders and his colleagues studied errors of train drivers, vehicle drivers, airplane drivers, and medical practitioners in terms of their processing visual information. (In 1960s, John drove in Boston wearing a helmet and a visor that occluded his vision to find how often drivers need to see front!) Then, they provided recommendations to the city of Toronto, simulate trainings for pilots, or even develop devices for doctors such as Head Mounted Display).

Since Human Factors research investigates human behavior issues elegantly, which has a great potential to business. Shumin Zhai, for instance, presented his business which was developed from a research project. About 10 years ago, his team developed an innovative text input system for a touch screen device. It does not simply improve a conventional keypad to make it easy to use (e.g., laying out keys differently). Rather, it allows users to use their gestures to input texts. It is now called as ShapeWriter.

To me, Don Norman‘s call for Human Factors researchers to work with business people sounds right. I believe designers need business education to communicate with business people effectively. I found a wide variety of business-able issues were discussed in the symposium but hardly found any people with business background.

I hope to find more business students working at Human Factors community in the future.

Evolution of design thinking

1 Comment

In 2006, what was design thinking? (see more at Luke Wroblewsky‘s blog)

Roger Martin

When it comes to innovation, business has much to learn from design. The philosophy in design shops is, ‘try it, prototype it, and improve it’. Designers learn by doing. The style of thinking in traditional firms is largely inductive – proving that something actually operates – and deductive – proving that something must be. Design shops add abductive reasoning to the fray – which involves suggesting that something may be, and reaching out to explore it.

Tim Brown

Because it’s pictorial, design describes the world in a way that’s not open to many interpretations. Designers, by making a film, scenario, or prototype, can help people emotionally experience the thing that the strategy seeks to describe.

Jeanne Liedtka

Design thinking is synthetic. Out of the often-disparate demands presented by sub-units’ requirements, a coherent overall design must emerge. Design thinking is abductive in nature. It is primarily concerned with the process of visualizing what might be, some desired future state and creating a blueprint for realizing that intention. Design thinking is opportunistic: the designer seeks new and emergent possibilities. Design thinking is dialectical. The designer lives at the intersection of often-conflicting demands – recognizing the constraints of today’s materials and the uncertainties that cannot be defined away, while envisioning tomorrow’s possibilities.

..

Now in 2010, what is design thinking?

I recently came across a carefully written post at Core 77 about design thinking. It was done by Kevin McCullagh and titled as “Design thinking: Everywhere and Nowhere, Reflections on The Big Re-Think.”

In fact, design thinking always meant different things to different players. For some it was about teaching managers how to think like designers; for others, it was about designers tackling problems that used to be the preserve of managers and civil servants; and for others still, it was anything said on the subject of design that sounded smart. To most, it is was merely a new spin on design. All its proponents were, however, united by their ambition for design to play a more strategic role in the world than ‘making pretty.’ Who could argue with that?

..

Now in 2023, what is design thinking?

People are gravitated towards different attitudes about design thinking. Some are disappointed by the fact that design thinking fails to produce visible, lasting outcomes. Others pay attention to its unique role in helping people creative. Design thinking might not be a short-term, direct tool, but rather a long-term, indirect mindset.

Organizations have sought to adopt design thinking aiming at innovation. However, implementing such a creative problem-solving approach based on designers’ mindsets and practices requires the navigation of obstacles. Corporate structure and culture hinder the adoption course, and cognitive barriers affect non-designer engagement. In this regard, training has been used as a means of easing the process. Although considered a crucial step in design thinking implementation, research on training initiatives is scarce in the literature. Most studies mirror that about d.school boot camp and innovative programs developed by companies globally remain unknown. This practice-oriented paper investigates a training blueprint tailored for LG Corporation in South Korea, targeting R & D personnel working in several affiliates that needed creative problem-solving skills to improve business performance. The study findings unveil a customized initiative that expanded the established boot camp model by adding preceding activities to increase learning opportunities and enable empathetic observation. Fundamentally, the customization strategy aimed to provide participants with customer-oriented tools to solve business problems. In addition, the training program reframed the design thinking steps in order to make it relevant for employees and foster corporate implementation goals. Ultimately, this case study supplies literature describing a training blueprint to disseminate design thinking considering two dimensions: individual adoption and organizational implementation challenges.

Context for good design

1 Comment

Many design awards have their own answers about what makes a product well designed; it must be original, it must be aesthetically appealing, and it must be useful. Similarly, marketing researchers have also studied that newness, beauty, and usefulness contributes to the evaluation of a product. However, whether product usage context or the outer space of a product affects whether a product is well designed has been little discussed.

I found a nice example which shows the impact of usage context on design. Designers from Industrial Facility, a UK design studio, developed a Bath Radio for Muji. It is a radio but looks like a set of shampoo and rinse. This example shows that consumers may consider a product well designed when its design matches its usage context.

Jump Associates, unique office

3 Comments

Last summer, I visited two design consulting firms in California: IDEO and Jump Associates. Visiting them raised several interesting research questions.

I was impressed by the space of the “Jump Associates.” It occupies two floors in one building and the two floors are connected by a steel stair inside the building. Employees can freely go up and down without using the external elevator. Besides, Jump Associates has several interesting rooms including “Zen Room.” This room has a low ceiling with several cushions. The Zen Room is often used for consumers who want to express their needs and ideas in a warm, comfortable setting. This is interesting because I have not seen any work telling the value of small sized space with a low ceiling. Instead, much work suggests that high ceiling facilitates creativity.

I wonder if spaces (rooms and their ceiling heights) are carefully selected for different stage gates of a product development process. Designers may want to collect consumer needs in a low-ceiling, close space but they may want a high-ceiling, open space to generate concepts.

IDEO, three roles of prototypes

2 Comments

Prototypes have different forms. According to an article written by two apple computer employees, Houde and Hill (1997), prototypes prototype the “role” of a product, its “look and feel,” or its “implementation.” Therefore, designers should choose a right type of a prototype.

One step further, prototypes serve different roles. When I visited IDEO last summer, I found three boards which describe what prototypes do; they “inspire,” “experiment (evolve),” or “validate (specify)” a product. This suggests that different types of prototypes can serve different purposes for a product.

Given that there are different types of prototypes and different objectives of prototypes, designers should create different types of prototypes for different objectives. For instance, the “role” prototype can be more appropriate when designers inspire a product, while the “look and feel” prototype can be better when designers validate a product.

Prototypes are widely recognized to be a core means of exploring and expressing designs for interactive computer artifacts. It is common practice to build prototypes in order to represent different states of an evolving design, and to explore options. How- ever, since interactive systems are complex, it may be difficult or impossible to create prototypes of a whole design in the formative stages of a project. Choosing the right kind of more focused prototype to build is an art in itself, and communicating its limited purposes to its various audiences is a critical aspect of its use.

Do people like an unexpected design of a product?

burger king

We often meet a product with a unique form and find it difficult to guess how it works. Examples include a donut-looking tape by 3M, a burger/fries/coke-looking USB key by Burger King, or a chocolate-looking mirror by Meiji, a Japanese chocolate manufacturer. One of my Japanese friends even pointed me a website in which a designer keeps posting his/her design prototypes (Prototype 1000).

I wonder whether consumers like a product more when its form and function are inconsistent than when they are consistent.

Noseworthy, T. J., & Trudel, R. (2011). Looks Interesting, but What Does It Do? Evaluation of Incongruent Product Form Depends on Positioning. Journal of Marketing Research, 48(6), 1008–1019.

Marketers struggle with how best to position innovative products that are incongruent with consumer expectations. Compounding the issue, many incongruent products are the result of innovative changes in product form intended to increase hedonic appeal. Crossing various product categories with various positioning tactics in a single meta-analytic framework, the authors find that positioning plays an important role in how consumers evaluate incongruent form. The results demonstrate that when a product is positioned on functional dimensions, consumers show more preferential evaluations for moderately incongruent form than for congruent form. However, when a product is positioned on experiential dimensions, consumers show more preferential evaluations for congruent form than for moderately incongruent form. Importantly, an increase in perceived hedonic benefits mediates the former, whereas a decrease in perceived utilitarian benefits mediates the latter. The mediation effects are consistent with the view that consumers must first understand a product’s functionality before engaging in hedonic consumption.

Designer vs. Consumer

3 Comments

Consumers find it difficult to evaluate an object when it consists of many components. For instance, they cannot evaluate whether the designer’s interior with furniture, clock, wall, and window is good or bad.

In this case, according to decision research, consumers should break down an object into detailed components in order to evaluate it better. Doing so helps consumers identify how much each component contributes to the object. This suggests that, for instance, if consumers find the value of furniture, the value of clock and the value of wall to the whole interior, they can evaluate the interior as a whole. At this moment, LEARNING needs; If consumers are exposed to multiple interiors and each of which has its evaluation score and various interior components, consumers are able to LEARN how much each interior component contributes to each interior. In sum, breaking down a holistic object into components and learning the degree to which each component contribute to the holistic object help consumers evaluate the holistic object.

Interior2

Recently, I believe that there is an alternative way to evaluate a holistic object; instead of breaking it down into pieces but by putting together the pieces. Doing so helps consumers infer the THEME that designers propose. If the designer decides the theme of her interior as jungle, for instance, she may choose a brown desk and green chairs to represent a tree with leaves, paint the walls with red dots to represent bugs, and place a round-shaped yellow clock on the wall to represent the sun. If consumers identify the jungle theme, they will be able to evaluate how much each component contributes to the theme.

Now, my question is whether consumers identify the designers’ themes. Put differently, I wonder whether consumers can reversely engineer the designers’ messages? If not, how can we help consumers find them?
