Yesterday, the Nielsen Norman Group released groundbreaking research on user interface design for dogs:
There are several key usability guidelines that help dogs to have the most usable experience on modern websites and apps, particularly on mobile, tablet, and other touch-based interfaces:
- Consistency is critical. While consistency in any user experience is important, with dogs, it’s even more so. Experienced dog trainers will tell you that, for dogs to learn proper behavior, consistency in enforcing routines, expectations, and commands is critical. Some common UI culprits that provide extra difficulty for dogs are swipe ambiguity, gestures without signifiers, tap uncertainty for flat UI elements like ghost buttons, and unusual placement of common elements like navigation and search.
- Tap targets must be large. We recommend 1cm2 for human tap targets, but paws (whether belonging to cats or dogs) require larger tap sizes (of at least 3-4cm2, or even larger for Labradors and Great Danes).
- Gestures must be ergonomic for dog physiology. While many wearable interfaces now involve gestures such as swiping left or right to dismiss notifications or switch apps, these need to be modified for more ergonomic canine movements (such as “shake”). Dogs have a greater ability to move paws with precision up and down, but dogs’ range of motion along the horizontal axis is limited and relatively imprecise, so all gestures must account for this limitation.
They also give special guidance on the risks of using hamburger menus and pie charts.
