Many researchers have been concerned with social media and possible negative impacts on the well-being of their audience. With the popularity of social networking sites (SNS) steadily increasing, psychological and social sciences have shown great interest in their effects and consequences on humans. Unfortunately, it appears to be difficult to find correlations between SNS and the results of their works. We, therefore, investigate Facebook using the tools of HCI to find connections between interface features and the concerns raised by these domains. With a nod towards Dark Patterns, we use an empirical design analysis to identify interface interferences that impact users' online privacy. We further discuss how HCI can help to work towards more ethical user interfaces in the future.

This workshop paper presents two proxy objects for high fidelity interaction in virtual reality (VR): a paper map and a smartphone. We showcase how our virtual paper map can increase interactivity and orientation, while our virtual smartphone extends the use of a proxy object, as it allows for actual touch input on a real phone leading to an almost infinite set of possible (inter-)actions (e.g. snapping pictures in the virtual world). Observations showed that participants were very precise in holding and interacting with both the paper map and the smartphone even though they did not see their hands in VR. The interaction in general was very intuitive which was mostly attributed to the realistic size of the virtual objects. Using our findings we discuss the trade off between adaptivity and high fidelity of proxy objects in VR.
