Manual assembly tasks require workers to precisely assemble parts in 3D space in parallel steps. Often, additional time pressure further increases the complexity of these parallel tasks (e.g. in adhesive bonding processes). The performance in parallel tasks is heavily influenced by the capacity of the working memory, which is often overwhelmed if r...
Conference Paper
Stress is a risk factor in safety-critical environments. It increases the probability for errors, which in turn can possibly be detrimental to human health and damaging to materials. While some industries have already turned to stress training in virtual reality (VR), the nursing profession still finds itself in the early stages of adopting the tech...

Augmented Reality (AR) devices and applications are gaining in popularity, and-with recent trends such as Pokemon Go-are venturing into public spaces where they become more and more pervasive. In consequence, public AR displays might soon be part of our cityscapes and may impact on our everyday view of the world. In this work, we present ChalkboARd...
Conference Paper
Nurses in intensive care units (ICU) are often exposed to noise pollution, especially a high number of acoustic patient alarms. One widespread consequence of these alarms is a condition called alarm fatigue. This means a desensitization and a resulting decreasing response time to alarms. To reduce the number of alarms, many interventions have been...

Navigation systems for cyclists are commonly screen-based devices mounted on the handlebar which show map information. Typically, adult cyclists have to explicitly look down for directions. This can be distracting and challenging for children, given their developmental differences in motor and perceptual-motor abilities compared with adults. To add...
Conference Paper
With increasing ubiquity, wearable technologies are becoming part of everyday life where they may cause controversy, discomfort and social tension. Particularly, body-worn "always-on" cameras raise social acceptability concerns as their form factors hinder bystanders to infer whether they are "in the frame". Screen-based status indicators have been...

Current head-mounted displays (HMDs) have a limited field-of-view (FOV). A limited FOV further decreases the already restricted human visual range and amplifies the problem of objects receding from view (e.g., opponents in computer games). However, there is no previous work that investigates how to best perceive moving out-of-view objects on head-m...

Everyone who has visited a patient in an intensive care unit will still remember the constant noise emitted from a number of highly sophisticated technical systems. For critical care nurses this creates a working environment in which about 350 alarms per patient are issued and each care taker is responsible for several patients at the same time. Al...
Conference Paper
Bystanders have little say in whether they are being recorded by "always-on" cameras. One approach is to use gestural interaction to enable bystanders to signal their preference to camera devices. Since there is no established gestural vocabulary for this use case, we explored gestures to explicitly express consent (Opt-in) or disapproval (Opt-out)...
Conference Paper
Full-text available
Knowing the locations of spatially distributed objects is important in many different scenarios (e.g., driving a car and being aware of other road users). In particular, it is critical for preventing accidents with objects that come too close (e.g., cyclists or pedestrians). In this paper, we explore how peripheral cues can shift a user's attention...
