I’m becoming increasingly fascinated with the parallels between architecture and web design. Dan Lockton recently published Architecture, urbanism, design and behaviour: a brief review – it’s an extract from his PhD thesis where he discusses how architecture can be used to influence behavior. It’s a long article, but well worth your time – I highly recommend it.
It’s full of architecture concepts that can be applied to designing for the web, but I want to discuss one in particular – the idea of “paving the cowpaths”:
One emergent behaviour-related concept arising from architecture and planning which has also found application in human-computer interaction is the idea of desire lines, desire paths or cowpaths. The usual current use of the term [“¦] is to describe paths worn by pedestrians across spaces such as parks, between buildings or to avoid obstacles “” “the foot-worn paths that sometimes appear in a landscape over time” (Mathes, 2004) and which become self-reinforcing as subsequent generations of pedestrians follow what becomes an obvious path. [“¦]
[T]here is potential for observing the formation of desire lines and then ‘codifying’ them in order to provide paths that users actually need, rather than what is assumed they will need. In human-computer interaction, this principle has become known as “Pave the cowpaths” “” “look where the paths are already being formed by behavior and then formalize them, rather than creating some kind of idealized path structure that ignores history and tradition and human nature and geometry and ergonomics and common sense” (Crumlish & Malone, 2009).
Particularly with websites, analytics software can take the place of the worn grass, and in the process reveal extra data such as demographic information about users, and more about their actual desires or intention in engaging in the process. [“¦] This allows clustering of behaviour paths and even investigation of users’ mental models of site structure. [“¦]
From the point of view of influencing behaviour rather than simply reflecting it, the principle of paving the cowpaths could be applied strategically: identify the desire lines and paths of particular users “” perhaps a group which is already performing the desired behaviour “” and then, by formalising this, making it easier or more salient or in some way obviously normative, encourage other users to follow suit.
This is such an interesting perspective on user-centred design. We all know that we need to design for real user needs, and not what we think they want, but it’s often so hard to do all our design work from that perspective. That’s where real-world analogies like this can be extremely helpful.
