Hidden things and implicit interaction
José Cezar de Souza Filho, Andréia Libório Sampaio, Eduardo Luzeiro Feitosa · 2022
Invisibility in Ubiquitous Computing (UbiComp) and Internet of Things (IoT) systems refers to the merge of technology in the environment or the interaction workload decrease so that users can focus on their daily activities. It has been a fundamental attribute for these systems since the UbiComp advent and has received different names and definitions over time. However, there is a lack of retrospective studies investigating how these perspectives contributed to the current concept of Invisibility. Therefore, this paper aims to understand how Invisibility evolved as a quality-in-use attribute. We applied the snowballing method to search for literature evidence about the attributes and interaction evaluation approaches related to Invisibility. We identified eight related attributes: Intelligibility, Accuracy, Control, Customization, Non-obtrusiveness, Diffusion, Transparency, and Understandability. Also, we observed that the existing evaluation approaches consider only part of these attributes. Our findings suggest opportunities to improve the approaches and for future research.
