The checklist presented in this paper was designed to be useful for both researchers and practitioners. It combines pertinent information from relevant standards like ISO 9241-210 with results from current research literature and experience from several AR projects in industrial contexts. It can be applied both in collaboration with AR experts, where it helps to prepare relevant information for the collaboration and thus streamlines the process, or stand-alone, as a guideline for the evaluation of different options by a design team. }}, author = {{Paelke, Volker and Büttner, Sebastian and Mucha, Henrik and Röcker, Carsten}}, booktitle = {{Advances in Ergonomics of Manufacturing: Managing the Enterprise of the Future.}}, editor = {{Trzcielinski, Stefan}}, isbn = {{978-3-319-60473-2}}, issn = {{2194-5365}}, keywords = {{Augmented reality, Displays, Evaluation, Checklist, Context of use, Human-Computer interaction}}, location = {{Los Angeles, California, USA}}, pages = {{225--234}}, publisher = {{Springer}}, title = {{{A Checklist-Based Approach for Evaluating Augmented Reality Displays in Industrial Applications}}}, doi = {{10.1007/978-3-319-60474-9_21}}, volume = {{606}}, year = {{2017}}, } @inproceedings{4373, abstract = {{Today, usability measures for the evaluation of systems and interfaces are mostly assessed in an isolated way.

For the evaluation of emotions, we used verbal methods (PAD Semantic Scale and a questionnaire) and a nonverbal method with EmoCards.

For this reason the objective was to examine mental models in terms of anthropomorphic perception of smart home environments and its relation to trustworthiness. Two studies (N=36) were carried out in the Future Care Lab, a simulated intelligent home environment. We used the teach-back method to help participants to talk about the smart home environment technology and asked to generate a metaphor of an experienced home-monitoring scenario. Finally, we applied linguistic analysis of responses to detect anthropomorphic characteristics. In general, results demonstrate inspiring metaphors related to the personal assistance system, e.g. "like an airbag…" or "like a family member…", which might be useful for future interface designs and approaches of communication in the context of smart home environments. However, no relation of anthropomorphism and trustworthiness could be found.

Instead, it is argued, that the trade-off is not of fundamental nature, but caused by neglecting elementary aspects in the design process.

To verify the validity of the conceptual approach, several evaluations were conducted.
