Interactive worker assistance: comparing the effects of in-situ projection, head-mounted displays, tablet, and paper instructions
TLDR
This paper aims to close the gap between HMD instructions, tablet instructions, and baseline paper instructions to in-situ projected instructions using an abstract Lego Duplo assembly task and shows that assembling parts is significantly faster and locating positions is significantly slower using HMDs.

Using a touch-sensitive wristband for text entry on smart watches
TLDR
This paper proposes a text entry technique using a touch sensitive wristband and argues that the inexpensive sensors enable the integration in low cost wearable watches that require text entry occasionally. Expand
The Design Space of Augmented and Virtual Reality Applications for Assistive Environments in Manufacturing: A Visual Approach
TLDR
A visual approach towards assessing the design space of industrial augmented and virtual reality keeps diversifying is proposed and an interactive, community-driven tool is presented which supports interested researchers and practitioners in gaining an overview of the aforementioned design space. Expand
A benchmark for interactive augmented reality instructions for assembly tasks
TLDR
A standardized experiment design for evaluating interactive instructions and making them comparable with each other is proposed and a General Assembly Task Model is introduced, which differentiates between task-dependent and task-independent measures. Expand
Design approaches for the gamification of production environments: a study focusing on acceptance
TLDR
The results reveal that a pyramid design showing each work process as a step on the way towards a cup at the top is strongly preferred to a more abstract approach where the processes are represented by a single circle and two bars. Expand
Using Head-Mounted Displays and In-Situ Projection for Assistive Systems: A Comparison
TLDR
A user study at a manual assembly workplace reveals that both in-situ instructions and paper instructions lead to significantly faster task completion times and significantly fewer errors than HMDs. Expand
Pick from here!: an interactive mobile cart using in-situ projection for order picking
TLDR
A mobile camera-projector cart called OrderPickAR, which combines the benefits of both stationary and mobile systems to support order picking through Augmented Reality, and dynamically projects in-situ picking information into the storage system and automatically detects when a picking task is done. Expand
Comparing Tactile, Auditory, and Visual Assembly Error-Feedback for Workers with Cognitive Impairments
TLDR
A comparison of tactile, auditory, and visual error feedback in a user study with 16 cognitively impaired workers reveals that visual error Feedback leads to a significantly faster assembly time compared to tactile error feedback. Expand
ABBAS: An Adaptive Bio-sensors Based Assistive System
TLDR
ABBAS, a novel integration of four different bio-sensors into an assistive system, using in-situ projection for providing feedback and measuring workers' stress levels during assembly work tasks through bio-Sensors in real-time is presented. Expand
Towards a gamification of industrial production: a comparative study in sheltered work environments
TLDR
It is shown that gamification leads to a speed-accuracy-tradeoff if no quality-related feedback is provided and that there is a highly significant raise in acceptance if a straightforward visualization approach for gamification is used. Expand
