Welcome to the first issue of SBC Journal on Interactive Systems in 2018.This edition starts with a special issue dedicated to Human-Computer Interaction. More specifically, it contains extended versions of five of the best full papers presented at the 14th Brazilian Symposium on Human Factors in Computing Systems (IHC’15). Our guest editors are Prof. Andreia Libório Sampaio, from the Federal University of Ceará (UFC), and Prof. Clodis Boscarioli, from the Western Paraná State University (UNIOESTE). We would like to thank them for preparing this special issue. You are invited to read their Guest Editors’ Note in the following.This issue also has a regular paper presenting the results of a joint work from groups of three Brazilian Universities: UFSCar, UNICAMP, and UFES. The paper is entitled “Applicability and evaluation of the GestureChair virtual game: comparison between people with and without spinal cord injury”, and produced evidence of relevant aspects of the use of VR games among people with spinal cord injury sequelae and a comparative group of people without injury.We hope you enjoy this issue of JIS and it encourages you to send us your own contributions.

Virtual Game

Introduction: Spinal cord injury rehabilitation requires updating from professionals regarding the possible interventions that can enhance recovery. Virtual reality (VR) games have become evident as a resource used in the rehabilitation process. Their effectiveness is based on the theory of neuronal reorganization, mediated by mirror neurons, responsible for motor imagery. Objectives: To test the applicability and evaluation of the virtual game Gesture Chair by people with and without spinal cord injury, to identify users' perceptions about the characteristics and demands of the VR game after its use and compare the immediate effects of the game on motor performance components in both groups. Method: We analyzed upper limb range of motion (ROM) after performing a practice using the exergame in a sample of five subjects with spinal cord injury and a comparative group with five other participants. The game was applied for 15 minutes, counting periods of activity and rest, while the subject remained seated. Results: The number of subjects in the sample does not allow statistically significant results on changes in shoulder ROM; however, factors that interfered with performance, perceptions about initial contact with the activity, presence of muscular fatigue and pain that may be present related to the increase of energy expenditure during the action were identified. Regarding the interest, there were reports of demotivation and disinterest, but there were also reports considering the activity motivating. Conclusion: The study implies the importance of the process of choosing individualized resources during the rehabilitation process and the need for adaptation among users of novel technologies. Future studies will be able to analyze the enhancement of the game with different users.
