How the iPhone Design Appeals to our Brains
Published on: September 12 2017
Apple products, including the iPhone, appeal to us with their attention to good design. The influence of designs isn’t just rational, it communicates to us on an emotional and subconscious level. For this reason, we can’t always describe it well in words. It creates a feeling and we might not understand the ways that the product is visually appealing to our subconscious. Whilst each new iPhone launch involves discussion of the latest features – camera quality, screen resolution, battery life – the design of the device itself has been just as precisely engineered to create this emotional appeal.
Design is a way to differentiate products that may have similar functional capabilities. Since its launch ten years ago, the iPhone has inspired many imitators, and other smartphone brands are competing within the same range of technical capabilities. Yet why do certain brands of phone inspire such strong feelings in their fans?
Could the global success of the iPhone explained by the way it follows a set of specific principles of how things visually appeal to our brains?
Neuroscience studies on how people automatically react to different designs lead me to believe that Apple are – either deliberately or accidentally – using principles that visual neuroscience tells us work well in design.
In particular, there are four things that Apple does exceptionally well with the iPhone that help it appeal to our brains: 1. First impressions
Apple make efforts to ensure that the design of each new version of the iPhone doesn’t leak before their official launch. This allows them to carefully control the exact way that the public first see their product.
Neuroscientists have discovered that we can form an impression within seconds (sometimes in less than a second) of first seeing a product or image, and this impression will then stick(1) . Our later feelings and attitudes towards the product will have been shaped by this first reaction. Therefore, getting this right, and presenting a product in its best light, will help frame our long-term feelings towards it.
In addition to its technical capabilities, the presentations in which Apple first reveals each new iPhone typically also focus our attention on its appearance and design features. Neuroscience would suggest that this has a big impact on guiding how we all feel about the iPhone.
2. Pleasing proportions
Since classical times, designers and architects have been tapping into our brain’s in-built love for certain proportions. One of these is a shape known as the golden rectangle. This is a rectangle with particular proportions: the long sides are 1.6X the length of the short sides.
Whether it’s in ancient Greek temples, or Renaissance paintings, we see rectangles of these proportions in many beautiful designs.
It just so happens that the iPhone’s screen – like many successful products – is approximately in the form of a golden rectangle. The proportions aren’t exact, but visual neuroscientists have found that there is a range of rectangle height-to-width ratios that we find pleasing (2).
Of course, this shape also is a good shape for fitting into the palm of our hands, so its visual appeal may be accidental, yet it is nevertheless there!
3. Unexpectedly familiar
Psychologists have long known that the more familiar something looks, the more we tend to like it. They call it the ‘mere exposure effect’ (3).
However, more recent studies have shown that things are a bit more complicated.
We all know that things that are too familiar can appear boring, and that we all can be attracted to looking at something just because it's new. What subsequent studies show is that images that are familiar, yet still have a touch of the unexpected, are particularly appealing to us (4). A good example of how this works in real life is if you bump into someone familiar to you – such as a friend or neighbour – in somewhere you don’t usually expect to see them – such as in the airport, for example – it can put a smile on your face in a way that it wouldn’t if you just saw them in the usual environment.
4. Intuitive physics
A relatively new area of psychology – called embodied cognition – studies how we use our bodies and our knowledge of the physical sensations of the world to influence our thinking and emotions. For example, this can be seen in how we talk about things: if something is important we might describe it as ‘weighty’ or ‘heavy’, or if something is hard to do we might describe it as ‘rough’ (and, conversely, easy things as ‘smooth’).
From the time we’re babies we are used to understanding things through their physical features like weight, smoothness or temperature. It comes easy to us, and because we don’t have to think about it too hard it feels intuitive and therefore pleasing.
The iPhone, since its original launch, has incorporated a number of these types of physical-world metaphors to help make the product look and feel intuitive. For example, the iPhone introduced the user-interface techniques known as rubber-banding (the way the screen will snap-back, like a rubber band when scrolled as far as it will go and let go) and inertial scrolling (the way a screen will continue to scroll after your finger has left the screen, as though it had its own inertia, like something physical) to smartphones.
My interest in understanding the subconscious drivers of product appeal has led me to design a test on the new iPhone design, to run on the day of its launch. The test doesn’t rely on asking people questions, but rather uses a technique that was developed in psychology labs in the 1980s and ‘90s called ‘implicit response testing’. This allows us to measure people’s automatic and subconscious responses to a design. In essence we hope to pick up how appealing the new design is to people subconsciously. Check back within a few days to see the results!
