Where would you like to sit?

brightly coloured simple folding chairs in an outdoor cafe setting.Tanisha Cowell gives her perspective on seat design as an occupational therapist and interior designer. She says her five features for great seats is not rocket science and seems common sense, but as always, it’s the little details that make a difference. Of course backrests and armrests get a mention, but also where to place seating, say in a park or a cafe. Did you think about colour contrast and height of the seat, or even the thickness of a seat? Tanisha has something to say about these too. And what about a cushion for the leisurely Sunday breakfast at your favourite cafe?

Open Sesame! Packaging made easy

Exploded view of the package and all its partsIn marketing terms, the packaging is part of the product. The package shape, colour and brand are important in enticing consumers to buy. But all too often we have to get a sharp knife, a pair of scissors and wrestle with the packaging in order to get to the product inside. Microsoft has come up with a nice solution to packaging their Xbox Adaptive Controller – a gamepad for people who might not have use of their limbs. Good thinking – no good having a nicely designed accessible product that you can’t get out of the box! The video below shows the simple but effective design. There is another video on the FastCompany website or see the engadget website. Package designers take note. 

The title of the article is How Microsoft fixed the worst thing about product packaging.

How to assess inclusivity?

A woman is carrying a tray of foodThere is some debate on whether personas rather than real people should be used to assess whether a design is accessible, inclusive and useable. So what might be different about “quantitative persona”? The Inclusive Design Team at the University of Cambridge have developed persona that represent different groups of people with similar capabilities, which is enhanced with other personal information. The aim is to see how many people in the population might be excluded from using a particular product or performing a particular task. Their research is reported in a paper where they assessed the task of carrying a tray of food across a cafe, taking into account how using mobility aids restricts hand use. The title of the paper is, Evaluating inclusivity using quantitative personas. The full paper is available by request from ResearchGate. 

AbstractExclusion assessment is a powerful method for assessing inclusivity in a quantitative way. However, its focus on capability data makes it difficult to consider the effect of other factors such as different ways of using a product. We propose addressing this by combining exclusion assessment with quantitative personas. Each persona represents a group of people with similar capabilities, and is enhanced with other personal information. The capabilities of each persona are compared against the product demands to assess whether they (and thus the group they represent) could do a task. The additional persona information helps to determine how they approach and conduct the task. By examining personas that cover the whole of the target population, it is possible to estimate the proportion of that population who could complete the task. We present a proof-of-concept study using personas created from Disability Follow-up Survey data. These were used to assess the task of carrying a tray of food across a cafe, taking into account how using mobility aids restricts hand use.

Inclusive Self Service Terminals

A pink cupcake ATM.Gone are the days of having face-to-face customer service as we transition to the digital age and the Internet of Things. Self Service Terminals (SST) in banks, shops, and transport hubs are taking over and humans are disappearing. So, how to make these terminals accessible and useable by all? Well it starts at the beginning of the design phase. At a recent conference, Computers Helping People with Special Needs, held in Austria, there were seven papers focused on this topic dealing with design issues and standards for self service. One paper was about SST in Norway, another about standards development and yet another about touchscreens.  See below for abstracts. You will need institutional access   for a free read.

Accessibility of Self-Service Terminals in Norway  Abstract: 

This short paper outlines a project on SST accessibility conducted by Funka on behalf of the Norwegian Agency for Public Management and eGovernment (Difi). The aim of the project was to establish a set of usable guidelines for the accessible placement of SSTs in Norway. To do this, Funka reviewed and compared the relevant existing standards. From the resulting corpus, Funka culled requirements relevant to issues of placement and harmonised them. The eventual result was a step-by-step guide for the accessible placement of self-service terminals. Funka would like to continue the work on role-based filtering tools. Funka has already launched such a tool for its Swedish market, drawing on several open-source standards. Something similar could be done for SST accessibility on the basis of, for instance, the EN 301 549 European standard.

Standards Guidelines and Legislation Related to Self-service Technologies Abstract: 

The intention of the standards, guidelines and legislation discussed here, along with other initiatives mentioned, is to ensure accessibility for all is built into self-service technologies from the outset. This paper presents developments in relevant standards, guidelines and legislation since 2013. In reporting on this work, the intention to give an idea of its scope, but also to place these standards, guidelines and legislation within a critical framing that reviews both the material and its impact on efforts to make SSTs accessible to all users.

Accessible Touch: Evaluating Touchscreen PIN Entry Concepts with Visually Impaired People Using Tactile or Haptic Cues, Abstract:

Findings are presented from a user test of several different concepts to enable personal identification number (PIN) entry on a touchscreen by people who are blind or partially sighted. A repeated measures experimental design was used for the user test, with all participants using all concepts in a randomised order. Results are presented, and wider implications of this study and the subsequent approvals are discussed.

How can you sell more ice cream?

packshots of ice cream and detergent and the increase in salesThe answer is simple: improve the design of your packages and images to make them more inclusive. But it seems corporates are slow to change their approaches to design, instead preferring to stay with “tried and true” methods. The Inclusive Design Team at the University of Cambridge has been working on this issue for 15 years. They have come up with a three key components that help persuade businesses to think about their product and label designs from a different perspective. The title of the paper is, “Using Inclusive Design to Drive Usability Improvements Through to Implementation”. The article can be found on ResearchGate.  or a book chapter in Breaking Down Barriers, a SpringerLink publication. The image shows the rise in sales after changing the pack-shot with Mini-Magnums increasing by 24%.

Abstract: There are compelling reasons to improve usability and make designs more inclusive, but it can be a challenge to implement these changes in a corporate environment. This paper presents some ways to address this in practice based on over 15 years experience of inclusive design work with businesses. It suggests that a successful persuasive case can be built with three key components: a proof-of-concept prototype, an experience that enables the stakeholders to engage personally with the issues and quantitative evidence demonstrating the impact of a potential change. These components are illustrated in this paper using a case study that was conducted with Unilever to improve the images used in e-commerce. The ice cream brand, Magnum is one of Unilever’s billion-dollar brands that implemented these changes. During an 8-week live trial, comparing the old and new images, the new images experienced a sales increase of 24%.

Bridging the exclusion gap

inclusive design toolkitThe Inclusive Design Group based at the Engineering Design Centre, University of Cambridge (UK) have been working over many years to find ways to demonstrate to product designers how many potential users are excluded from using, and therefore purchasing, their products. They first published the Inclusive Design Toolkit and have continued enhancing this work. Two gadgets to help designers, gloves and glasses, are now available. Using a pack of Post-it Notes as an example Sam Waller demonstrates in the video below how many people will find it impossible to remove the cellophane wrapping. A good case of including people with low vision and/or arthritis is good for everyone and increases market size.

Manufacturing a UD design process

aerial view of three people at a desk looking at a set of construction drawingsA straightforward introduction to this paper from Japan argues that UD should have been thought of a long time ago, but wasn’t. So inclusive thinking hasn’t been part of conventional design processes. This poses difficulties for industrial designers, and if being inclusive doesn’t fit their processes, there is a tendency for designers to put UD in the “too hard” basket. The authors have developed a design process model that takes designers from conventional design processes to one that is more inclusive. The title of the paper is Universal Design Models of Development Lifecycle Process. Here is an excerpt from the introduction:

“UD should originally have been the basic concept behind manufacturing, but lack of recognition until now has created a large gap between the ideal and reality. Hence, many of the responsibilities will fall on the UD designers. As a result, designers will request from the UD promoters only a list of minimum UD requirements and asking them to settle for simple, offhand solutions to avoid developmental delays. In response, the UD promoters will emphasize the need to implement more than the minimum requirements by pointing out the difficulties of overcoming conflicts that arise from various user demands. Convincing the designers is a hard task. Currently there are very few examples or methods to explain the differences between conventional and UD design processes. Many times the designers think that UD design process will be the same as conventional ones, or they give up because they believe numerous UD knowledge and experiences are necessary.”

The paper then goes on to describe three ways of re-thinking the design process. Although somewhat technical in parts, it is another view of how to think about designing universally.

conference logo The paper was presented at the 2nd International Conference for Universal Design in Kyoto 2006 (just released on Research Gate). It was attended by 14,000 participants from 29 countries. Their next conference will be held in Thailand 4-6 March 2019
