We evaluated a web-based communication tool for nurse scheduling using two common usability evaluation methods, heuristic evaluation and end-user think aloud protocol. We found that heuristic evaluation performed by human-computer interaction (HCI) experts revealed more general interface design problems, while end-users' think-aloud protocols identified more obstacles to task performance. To provide the most effective and thorough evaluation results, a combination of heuristic evaluation and end-user think-aloud protocol is recommended.
我们使用两种常见的可用性评估方法,即启发式评估和最终用户出声思维协议,对一种基于网络的护士排班沟通工具进行了评估。我们发现,由人机交互(HCI)专家进行的启发式评估揭示了更普遍的界面设计问题,而最终用户的出声思维协议则识别出了更多任务执行过程中的障碍。为了提供最有效、最全面的评估结果,建议将启发式评估和最终用户出声思维协议结合使用。
