With patients increasingly treating themselves at home, often using specialist equipment, the chance of use errors increases, and the ensuing results can be deadly.
User Interfaces (UI) have a key role to play in reducing the risk of use errors in a patient-used device, writes David Furley of PDD. In fact, he says, “the benefits of a good UI go beyond reducing errors. People generally like using products that feel easy to use and creating a device that patients feel good about has the potential to improve their well-being, increase treatment adherence and better overall health.”
Unfortunately, UIs of patient-used devices available today are often lacking. Furley suggests the following simple design principles to improve the user experience:
– Speak in a language users will understand
– Reduce reliance on instructions
– Reduce cognitive load
– Reduce capacity for errors
