With the increasing popularity of mobile devices, Healthcare Human Factors wanted to determine which popular mobile devices can best support various nursing tasks. Device usability was determined through metrics such as performance and user perceptions. The following five mobile devices were evaluated:
Test results indicated that ease-of-use, failure rates and task completion time on their own do not determine acceptance of mobile devices in the clinical environment. Nurses will forgo ease-of-use in favour of a more compact, lighter weight device.
The Blackberry Bold and iPhone 3G were found to be acceptable devices because of their size and speed. The Nokia N810 also met or exceeded the performance of these devices, but was generally considered too bulky and heavy for nurses to use on a routine basis. The Palm Treo 680 and HP iPAQ 210 are not recommended due to poor page rendering and slow performance.
