David Kelley: Human Centred Design

I think that there is real merit in understanding the ways a human interacts with a product and vice - versa. In an age where technology is leading innovation, it is essential that designers continue to employ the human being as the central focus.

In his 2002 TED talk, David Kelley presents a number of interesting case studies which help to explain the human centred nature of product design which has been evolving through the past 18 years. More as a prediction of what was to come, Kelley’s ideas were somewhat forward thinking at the time, concepts which we see incorporated in design extensively today.

He presents work completed for new Prada stores which are focused on creating a more immersive and engaging experience between the consumer and the clothing item he or she chooses. This includes bespoke RFID tag remote controls that can capture the clothing data and present it on screens displayed around the store. In conjunction with this, scanners in the changing rooms collect and present information and detail about the clothing items that were chosen to be tried on. Another interesting feature was the use of liquid crystal glass screens which turned opaque when a floor button was pushed. I’ve seen this technology now moving into the domestic environment, chosen as a unique was to achieve privacy and maintain an open – plan – like space.

In collaboration with Scott Adams, Kelley was asked to design the “ultimate cubicle for Dilbert,” and through the explanation of this process it was reiterated that a human engages more deeply with a product that can give something back – a pleasurable feel, appearance, an emotive response or recognisable action. Furthermore, although sometimes perceived as kitsch or dated, it is the personal items which, when used to accessorise the design, actually transform a cubicle space into a more user friendly environment – items that are recognised and have treasured value.

From this talk a lot can be taken away, though I believe the two most important factors are that humans form natural attachments to items of value or significance, and that an item needs to be engaging, designed with the human as the central focus.
