Bad design: Fresenius Applix Smart food pump

Fresenius food pump

The Fresenius Kabi Applix Smart food pump is a masterclass in bad design. There is nothing smart about this food pump and its accessories. It has been designed without taking into consideration the context in which it is to be used. Consequently, some of its accessories are not just safe enough to used around patients and the home and could lead to the compromise of patient safety.

When designing any form of interface, a usability consultant will push for the interface to be: effective and efficient; easy to learn and remember; useful and safe.

After usability comes user experience (in this medical context perceived user satisfaction is enough, as it is never going to be fun to use a food pump on a chronically ill person) which encourages users to feel supported and motivated by a helpful interface.

Fresenius Kabi has failed the user of the Applix Smart food pump on usability and user experience. (more…)

Why task analysis doesn’t do it for me

Like every self-respecting human-computer interaction (HCI) lecturer, I introduce task analysis or the technique of analysing how people perform a task or job, to my students a couple of weeks into a given course. Each time I am aware that I fail to get excited about task analysis and so give it a bad press. (more…)

Codebreaking: Humans are the weakest link

Sunday, October 21st, 2007

People are the weakest link in all computer systems. We hear about the best cryptography money can buy: integrity checking, sender/receiver identity authentication, digital signatures, and then someone leaves a list of passwords on a post-it note stuck above a computer and in an instant renders all the algorithms pointless. Or the same someone automatically gives out his password over the telephone or by email when ‘technical support’ asks so that they can reset it - another victim of phishing. (more…)

Human-computer interaction: Can you see what it is yet?

check out the video of this interface on ted.com

The recent furore over the 2012 Olympics Logo reminds me of how people react to the user interfaces they find on everything they interact with, from websites to washing machines. If an interface, like a logo, is well-designed, no one notices or mentions it. If it is difficult or unsightly, people complain loudly and when given a choice, won’t use an interface they don’t like. Interaction designers, like IT support staff, are never thanked when all is well and severely criticised when interfaces cause users problems. (more…)

Visualisation: Information is power - just avoid drowning in data

(The Great Fire of London map at the British Library website)

In the 1530s when Henry VIII realised that dissolving the monastries would get him much needed assets, he commissioned a map of London, paying particular attention to ‘lawless’ Southwark. He wanted to see if the borough had any money he could take off them. Henry VIII was a smart man, he knew that the right sorts of information bring wealth and power.

I saw the resulting map last year at the British Library exhibition London: A Life in Maps along with many others - maps of wills and estates, Victorian cab fare maps, cycling maps and tourist maps. Each map was primarily motivated by the need to learn more about an area of London in order to make or save money, especially when making your way around the ever growing London.
