Abstract

Purpose This study aims to investigate the usability of a public university website for measuring its efficiency, users’ satisfaction or anxiety while searching for and retrieving information through different devices. Design/methodology/approach A task-based approach was adopted for the study. Twenty-eight participants were asked to complete 11 information-searching tasks on the website. The participants were divided into two groups. The tasks were carried out by members of each group, using desktop and mobile devices in a rotating fashion. Volunteers observed the participants' actions and recorded information regarding their productivity, time usage (using a timer), satisfaction or annoyance while performing each task. Finally, based on the use of the devices, a comparison was established between the participants' performance accuracy, efficiency and anxiety. Findings The study provides an overview of a task-based user experience carried out on the university website using a combination of qualitative and quantitative research methods. According to the results, participants' satisfaction levels were generally high, and their anxiety levels were low while completing the tasks on a mobile device. In comparison to the desktop, it took less time overall to complete all tasks. On the other hand, using a desktop computer (97.1%) resulted in better task completion success rates for participants than using a mobile device (85.7%). Originality/value No previous task-based evaluation study of this kind has been conducted to assess the usability of any university website in Bangladesh.

通过不同设备对网站进行可用性测试：在孟加拉国公立大学环境中采用基于任务的方法

目的本研究旨在探讨一所公立大学网站的可用性，以衡量其效率、用户在不同设备上搜索和检索信息时的满意度或焦虑程度。设计/方法/方法本研究采用基于任务的方法。28名参与者被要求在网站上完成11项信息搜索任务。参与者被分成两组。这些任务由每个小组的成员轮流使用桌面和移动设备完成。志愿者观察参与者的行为，并记录下他们在执行每项任务时的效率、时间使用(使用计时器)、满意度或烦恼程度等信息。最后，根据设备的使用情况，对参与者的表现准确性、效率和焦虑程度进行比较。该研究结合定性和定量研究方法，对该大学网站上基于任务的用户体验进行了概述。结果显示，在使用移动设备完成任务时，参与者的满意度普遍较高，焦虑水平较低。与桌面相比，它完成所有任务所需的时间更短。另一方面，使用台式电脑(97.1%)比使用移动设备(85.7%)的参与者完成任务的成功率更高。原创性/价值以前进行过这种基于任务的评估研究，以评估孟加拉国任何大学网站的可用性。
