Abstract [en]

Ubiquitous computing environments can support clinical administrative routines in new ways. The aim of such computing approaches is to enhance routine physical work, thus it is important to identify specific design requirements. We studied healthcare professionals in an emergency room and developed the computer-augmented environment NOSTOS to support teamwork in that setting. NOSTOS uses digital pens and paper-based media as the primary input interface for data capture and as a means of controlling the system. NOSTOS also includes a digital desk, walk-up displays, and sensor technology that allow the system to track documents and activities in the workplace. We propose a set of requirements and discuss the value of tangible user interfaces for healthcare personnel. Our results suggest that the key requirements are flexibility in terms of system usage and seamless integration between digital and physical components. We also discuss how ubiquitous computing approaches like NOSTOS can be beneficial in the medical workplace.

Abstract [en]

Despite the introduction of computers in most work environments, the anticipated paperless workplace has not yet emerged. Research has documented that material objects are essential in the organization of thought and that they support everyday collaborative processes performed by staff members. However, modern desktop computing systems with abstract graphical user interfaces fail to support the tangible dimension. This work presents a novel approach to clinical computing that goes beyond the traditional user-interface paradigm and relieves clinicians of the burden of the mouse and keyboard.

The activities of people working in an emergency room were examined empirically to ascertain how clinicians use real paper objects. The results showed that the professionals arranged their workplaces and created material structures that increased cognitive and collaborative performance. Essential factors in these strategies were the availability of physical tools such as paper-based patient records and forms that could be spatially positioned to constitute reminders and direct the attention of the team, and to form shared displays of the work situation.

NOSTOS is an experimental ubiquitous computing environment for co-located healthcare teams. In this system, several interaction devices, including paper-based interfaces, digital pens, walk-up displays, and a digital desk, form a workspace that seamlessly blends virtual and physical objects. The objective of the design was to enhance familiar workplace tools to function as user interfaces to the computer in order to retain established cognitive and collaborative routines.

A study was also conducted to compare the tangible interaction model for clinical computing with a traditional computer-based patient record system with a graphical user interface. The analysis suggests that, in ordinary clinical environments, cognitive and collaborative strategies are better supported by the tangible augmented paper approach and a digital desk than the traditional desktop computing method with its graphical user interfaces. In conclusion, the present findings indicate that tangible paper-based user interfaces and basic augmented environments will prove to be successful in future clinical workplaces.
