Emotional Response Evaluation of Users in Ubiquitous Environments: an Observational Case Study

Ubiquitous systems can be characterized as providing transparency, while being context-sensitive and dynamically interactive. Evaluating ubiquitous environments involves challenges ranging from multidisciplinary areas to environmental simulations. However, few studies have been carried out on the users feelings and moods in these environments, i.e. within mental contexts. This paper undertakes an observational case study which involves evaluating emotional responses in ubiquitous environments. A number of volunteers were exposed to stimuli with the aim of changing their mood through colors and images, in accordance with their initial emotional state. Emotional responses were evaluated by means of a hybrid approach that entailed employing different evaluation instruments at different periods of the interaction and which took account of different stakeholders. The results suggest that the approach is appropriate, although some adjustments are required for the evaluation instruments, as well for the interaction time with the environment so that it is possible to collect further data about the users experience.

Re-evaluating the First Five Years of the GrandIHC-Br-Challenge 3: Ubiquity, Multiple Devices and Tangibility

Aiming to re-evaluate the actions of the Brazilian academic community to meet the challenges proposed in 2012 in the GrandIHC-BR, a discussion panel were proposed in 2017. This paper, part of the panel, presents a reassessment of the main contributions made by the Brazilian community to the advancement of the GranDIHC-BR Challenge 3. This challenge highlights the development of new devices through emerging technologies such as ubiquitous systems, multiple devices, and tangible user interfaces. We list and comment on papers published in the Brazilian Symposium on Human Factors in Computing Systems, since 2012, about these topics. Two artifacts of the Organizational Semiotics were used to support the identification of stakeholders and problems and possible solutions for the advancement of the Challenge 3. Finally, the main advances and suggestions for the continuity of researches are presented.
