Handheld technology finds slowly its place in the healthcare world. Some clinicians already use intensively dedicated mobile applications to consult clinical references. However, handheld technology hasn't still broadly embraced to the core of the healthcare business, the hospitals. The weak penetration of handheld technology in the hospitals can be partly explained by the caution of stakeholders that must be convinced about the efficiency of these tools before going forward. In a domain where temporal constraints are increasingly strong, caregivers cannot loose time on playing with gadgets. All users are not comfortable with tactile manipulations and the lack of dedicated peripheral complicates entering data for novices. Stakeholders must be convinced that caregivers will be able to master handheld devices. In this paper, we make the assumption that the proper design of an interface may influence users' performances to record information. We are also interested to find out whether users increase their efficiency when using handheld tools repeatedly. To answer these questions, we have set up a field study to compare users' performances on three different user interfaces while recording vital signs. Some user interfaces were familiar to users, and others were totally innovative. Results showed that users' familiarity with smartphone influences their performances and that users improve their performances by repeating a task.
手持技术在医疗保健领域正逐渐找到自己的位置。一些临床医生已经在大量使用专门的移动应用程序来查阅临床参考资料。然而，手持技术尚未广泛融入医疗保健业务的核心——医院。手持技术在医院的渗透率较低，部分原因是利益相关者持谨慎态度，在推进之前必须确信这些工具的效率。在一个时间限制日益严格的领域，医护人员不能在摆弄小工具上浪费时间。并非所有用户都对手指操作感到舒适，而且缺乏专用外围设备使新手输入数据变得复杂。利益相关者必须确信医护人员能够掌握手持设备。在本文中，我们假设界面的合理设计可能会影响用户记录信息的表现。我们还想了解用户在反复使用手持工具时是否会提高效率。为了回答这些问题，我们进行了一项实地研究，比较用户在记录生命体征时在三种不同用户界面上的表现。一些用户界面是用户熟悉的，而其他的则完全是创新的。结果表明，用户对智能手机的熟悉程度会影响他们的表现，并且用户通过重复任务来提高表现。
