Comparing Effectiveness, Efficiency, Ease of Use, Usability and User Experience When Using Tablets and Laptops
Initially perceived as a consumer device, in recent years tablets have become more frequently used in business contexts where they often replace laptops as mobile computing devices. Since they follow different user interaction paradigms we conducted a study comparing effectiveness, efficiency, ease of use, usability and user experience when using tablets and laptops in typical private and business tasks. To measure these characteristics we used the task completion rate, the task completion time, the Single Ease Question (SEQ), the Software Usability Scale (SUS) and AttrakDiff. Results indicate that there is a difference between effectiveness, efficiency and the users’ assessment of the devices. Users can carry out tasks more effectively and efficiently on laptops, but rate tablets higher in perceived usability and user experience, indicating that a pleasant and meaningful experience depends on more characteristics than work-related qualities such as effectiveness and efficiency.
