The application of immersive virtual reality for students with ASD: A review between 1990–2017

We live in a society where Technology has an important position in our diary activities. Everybody wants to have the last device to be in contact with his family and friends. Additionally, these took are being applied in other fields such as Education. One of these tools is: Virtual reality that can respond the need of our students. It allows the designer an important control of the system that can be useful for students with Autism Spectrum Disorder. These students can use Virtual Reality as a support to practice social situation that can be generalized in real environments. Therefore, our research provides a state-of-the-art review of what studies have applied Immersive Virtual Reality to students with Autism Spectrum Disorder. The sample of study has been 12 papers in the period 1996–2017. To analyse these research, it has been proposed these variables: participants’ features, research questions, instrument, type of activities, results, and limitations. These study variables have been chosen because they are the most repeated in all research using the experimental method. According to the results gathered: it has been worked with small sample, without control group and interactive activities. Moreover, the vast majority of the studies are focused on social skills.

New Educational Challenges and Innovations: Students with Disability in Immersive Learning Environments

In today society, one of the most demanded challenges faced by the current educational system is the educational response to diversity in the various educational contexts. University lecturers are opening new lines of research focused on issues as social demand and current reality of produced new learning environments. The general aim of this study was to design learning environments using immersive virtual reality and evaluate improvements produced by this tool in relation to the difficulties show by the participants. From that point, an action plan was created to recreate school situations with a high degree of realism and interaction using IVRSystem. In this way, we want to obtain answers according to the dysfunctions of educational system to work with these students. This was done by a mixed design. On the one hand, a quasi-experimental methodology was used with a control group and an experimental group. On the other hand, direct and observation and applicative methodology made possible the development of educational intervention in immersive learning environments. The results obtained throughout these years have given a response to the initial problem-question raised: Can immersive virtual learning environments serve as a support tool for working disabilities of students, which have a visual learning style, such as students with autism spectrum disorders?

Control of Redundant Joint Structures Using Image Information During the Tracking of Non-Smooth Trajectories

Visual information is increasingly being used in a great number of applications in order to perform the guidance of joint structures. This paper proposes an image-based controller which allows the joint structure guidance when its number of degrees of freedom is greater than the required for the developed task. In this case, the controller solves the redundancy combining two different tasks: the primary task allows the correct guidance using image information, and the secondary task determines the most adequate joint structure posture solving the possible joint redundancy regarding the performed task in the image space. The method proposed to guide the joint structure also employs a smoothing Kalman filter not only to determine the moment when abrupt changes occur in the tracked trajectory, but also to estimate and compensate these changes using the proposed filter. Furthermore, a direct visual control approach is proposed which integrates the visual information provided by this smoothing Kalman filter. This last aspect permits the correct tracking when noisy measurements are obtained. All the contributions are integrated in an application which requires the tracking of the faces of Asperger children.
