Interactive projections have been around for more than a decade. We measured their potentials for augmented workplaces in production. For this purpose we built the prototype of an assistive system projecting instructions directly into the workspace (in situ). While it can be applied in every production environment, the system was first implemented and tested where it is needed the most: in a sheltered work organization employing persons with impairments.It could be shown that the assembly times could be slightly reduced by the augmented system. However it had a "catalytic" effect on the test subjects' work quality: While some seem to be overwhelmed by the new information density and perform worse, others perform much better than the control group and significantly reduce error rates. The qualitative results show that although impaired persons retain a critical perspective on systems directly changing the way they have been working for years, all users would like to retry working with the system. When looking at additional aids like the projection of a real-sized model in the workspace, the users invariantly accept its benefits for their assembly work.

A worker performing a physical task may need to ask for advice and guidance from an expert. This can be a problem if the expert is in some distant location. In this paper, we describe a system which allows the expert to see the workplace from the worker's point of view, and to draw annotations directly into that workplace using a pico-projector. Since the system can be worn by the worker, these projected annotations may move with the worker's movements. We describe a method for sticking these annotations to the original positions thereby compensating for the movement of the worker. We call this 'StickyLight'. We conducted a user study to evaluate the performance and user preference for the system in 'sticky' and freehand ('non-sticky') modes. We also compared the system on two platforms: helmet mounted and tripod mounted. Results indicate that freehand conditions took less time than sticky, and that tripod conditions took less time than helmet. However, participants reported preferences for sticky over non-sticky, likely due to the relative discomfort of keeping the helmet steady. This echoes the findings of several recent similar investigations..

“…In order to do that, they had to pick up the correct objects -among the objects distributed around the room-and place them in the correct positions on a grid. The tasks selected for this study have the following properties: Accordingly, we selected this particular puzzle activity from the nine categories for manual tasks referenced in [11], however we normalized it to assess the quality of non-sequentially and spatial distribution of situated micro-displays. The independent variable of the study is the number of micro-displays.…”

Abstract. Most activity-aware systems designed to support mobile workers in dynamic environments, such as hospitals or industrial plants, typically consider the use of mobile devices and large displays. However, we envision potential benefits of using ubiquitous micro-displays as support of mobile workers activities. Particularly, in this paper we show how the use of situated micro-displays, as a mechanism for embedding information into a physical environment, can contribute to improve the performance and experience of mobile workers in those scenarios. The article also describes the prototype of a micro-display network designed to support people performing spatially distributed activities. It also presents a user study that helps understand how the spatial distribution of situated micro-displays impacts on the mobile workers performance.Keywords. Situated micro-display, activity-centric system, mobile work. IntroductionAdvances in wireless communication, sensor networks and ubiquitous computing have made possible the interaction between people and numerous devices that are interconnected and physically distributed in the environment [1]. These advances have promoted the evolution of single-monitor setups towards multi-display environments [2], where it is possible to have displays embedded in a physical ambient and also in everyday objects. Several studies on workplaces have shown how instrumented environments and everyday artefacts support people cognition and collaboration [3,4]. Researchers have emphasized the need to deliver task-centric information in dynamic workplaces, such as hospitals or industrial plants, as a way to support the activities performed by mobile workers [5,6]. Typically, situated information systems [7] provide information of the physical environment to mobile workers, and activity-aware systems [8] infer the workers' activity context in order to offer them suitable supporting services. Most of these systems types rely on the use of mobile devices and large displays [9]. However, recent researches [10] advocate for the use of micro-displays to provide situated information in activity-aware systems and offer activity-specific guidance. These micro-displays are mobile and adaptive. They are distributed across the environment and provide simple visual representations of human activities that are linked to physical entities -such as objects and people-and integrated in the environment.
