AppleInsider reports today that Apple's iOS 6 and iOS 7 software has performed impressively in a study carried out by tech consultants Pfeiffer Consulting. The study looked at quantitative user-experience data from iOS 6 and iOS 7 users, as well as Windows Phone 8, Samsung Android and BlackBerry 10 users. Pfeiffer says that their test methodology tried to eliminate as many subjective variables as possible, including the likes of â€œbrand loyaltyâ€ and â€œperceptionâ€, and only focus on objective â€œaspects that have a direct impact on the day-to-day user experience of an average, non-technical user.â€ The study looked at four key points: the OSâ€™s cognitive load, efficiency and integration, options for customisation, and user-experience friction. For cognitive load, iOS 7 was narrowly beaten by iOS 6. As far as efficiency and integration was concerned, iOS 7 was second to Samsung Android. For options for customisation, Samsung once again came first, with iOS 7 a close second. For the experience friction comparison, iOS 6 was the winner, with iOS 7 not far behind. In terms of the overall User Experience Index results, though, iOS 7 and iOS 6 took first and second place respectively, with the study finding that iOS 7 was the most user-friendly of the operating systems tested, saying, â€œApple has achieved its goal to move iOS into the modern smartphone era. Despite some controversial design aspects, iOS 7 is pleasant and more fluid to use than other mobile operating systems.â€ As originally reported by Maura on iPhoneforums.net Source: iOS 7 shines as Apple bests Android, Windows Phone in 'user experience shootout'
