Figure 1: We are targeting the problem of attention guiding in assembly and picking tasks (left). To be able to systematically and device independently evaluate own designs (bottom right) and established designs (e.g. arrow, top right), we simulate the application context and the AR device in virtual reality (middle). ABSTRACTA limiting factor of current smart glasses-based augmented reality (AR) systems is their small field of view. AR assistance systems designed for tasks such as order picking or manual assembly are supposed to guide the visual attention of the user towards the item that is relevant next. This is a challenging task, as the user may initially be in an arbitrary position and orientation relative to the target. As a result of the small field of view, in most cases the target will initially not be covered by the AR display, even if it is visible to the user. This raises the question of how to design attention guiding for such "off-screen gaze" conditions.The central idea put forward in this paper is to display cues for attention guidance in a way that they can still be followed using peripheral vision. While the eyes' focus point is beyond the AR display, certain visual cues presented on the display are still detectable by the human. In addition to that, guidance methods that are adaptive to the eye movements of the user are introduced and evaluated.In the frame of a research project on smart glasses-based assistance systems for a manual assembly station, several attention guiding techniques with and without eye tracking have been designed, implemented and tested. As evaluation method simulated AR in a virtual reality HMD setup was used, which supports a repeatable and highly-controlled experimental design.

Using video game elements to improve user experience and user engagement in non-game applications is called "gamification". This method of enriching human-computer interaction has been applied successfully in education, health and general business processes. However, it has not been established in industrial production so far.After discussing the requirements specific for the production domain we present two workplaces augmented with gamification. Both implementations are based on a common framework for context-aware assistive systems but exemplify different approaches: the visualization of work performance is complex in System 1 and simple in System 2.Based on two studies in sheltered work environments with impaired workers, we analyze and compare the systems' effects on work and on workers. We show that gamification leads to a speed-accuracy-tradeoff if no quality-related feedback is provided. Another finding is that there is a highly significant raise in acceptance if a straightforward visualization approach for gamification is used.
