We nearly passed out when we saw the original cookie messaging on Nestle’s UK site:
Where to start? Taking over the whole browser and firing this much information at the user completely disorientates them. Those big cross and tick icons? That’s where you click. There’s no other way to proceed. Despite the negative call-to-action, the ‘No’ column actually seems to be the one Nestle want you to go for, with five pros listed underneath, with the random ‘Yes’ what is it that “This website will not…” - we may never know.
Thankfully, someone seems to have had a quiet word, and they’ve now replaced it with a much more friendly banner at the top of the page:
This time the message explains what a cookie is, yet doesn’t interfere with the experience. It’s still not perfect though - the link accessibility is terrible, being dark grey and white on rollover without any underline, and a dismiss button would be nice.
Touch screen target sizes - virtual or physical?
Charbs flagged up this article by UX Movement, discussing mobile touch target sizes.
It’s a great article and a good starting point, but we’re not convinced pixels are the correct measurement to use due to the complexity of pixels per inch (PPI), and the massive variations across devices.
We think it’s better to design for an appropriate size/space on the screen, e.g. a button should be 1cm square. In terms of how we ensure that is achieved, we can help developers by specifying pixels, as the article suggests, but we need to be careful how that information is used when accounting for different devices, and be wary that screen densities vary massively.
The iPad 3 with its retina screen comes in at 264 PPI, as it has a big screen to go with the big resolution, but the iPhone 4S has much bigger PPI figure of 326. At the other end of the scale, the HTC Wildfire S has a decent sized screen but is only 320px wide, meaning 181 PPI. Some more examples can be found in WikiPedia’s List of displays by pixel density.
All this would seem to confirm that target sizes should be measured physically rather than in pixels.
Before we start, it’s worth pointing out that according to the UK Information Commissioner’s Office guidelines, if cookies are used as an essential part of the service being provided, no notification or consent is required.
The first example the Guardian cites is Delia Smith’s recipe and cooking community, Delia Online. Let’s take a more detailed look at the message:
According to the Guardian, the Information Commissioner’s Office suggested Reddbridge Media as a good solution (below). We’d suggest it’s far from perfect, presenting a conflicting mixture of statements and calls-to-action, with the white underlined text looking just like a link for added confusion:
