Abstract
The expectations related to the use of information and communication technologies, which their production and usage areas have become widespread rapidly, in education have been increased and so new approaches revealed in this context. One of these approaches is to use these technologies in special education. Individuals with special needs have difficulties in using technology. On the basis of this need, it has been stated that the use of natural user interface is helpful to increase daily life quality by removing difficulties on the use of technology that individuals with special needs meet (Turkoglu, 2010). The focal point of this research consists of motion-based technologies which provide natural interaction with the user and of the use of these technologies for individuals with special needs. There are many motion-based technologies but the most popular one is Kinect technology which involves perceptional interaction variations such as image processing and skeleton detection system. It is thought that motion-based technologies support the learning that they provide ease for the use and control for individuals who show typical growing and also who are special needed (Morency, Sidner, Lee and Darrell, 2007). In this sense, literature review about the use of motion-based technologies for acquisition of daily life skills and training of individuals with special needs have been made. At the end of the literature review, an analysis and a synthesis about what features motion-based technologies need to have and how they need to be used, as these technologies would be used for individuals with special needs by the determination of their positive and negative aspects for the use. A method which can be controlled by body movements has been determined as being more effective than traditional method, on the study that some of questions are demanded to be answers to evaluate a system that they use keyboard, mouse and body movements (Morency, Sidner, Lee and Darrell, 2007). When this case is evaluated especially for disabled individuals, it reveals how important such systems are. It can be provided that disabled individuals can find places that they look for, with the aid of perceptional interfaces which are haptic and perceive sounds for visually impaired persons (Zeng, Miao and Weber, 2015). Zhou, Qu, Jiao and Helander (2014) defense that audible warnings are as effective as visual stimulus. In this context, it is thought that the use of user interfaces perceiving sound would be beneficial for especially visually handicapped groups. It has been determined that methods which would be controlled by body movements are more effective than methods that tools such as mouse and keyboard are used, as methods provide natural interaction (Libardi, Traina and Rodrigues, 2014; Tong, Zhou, Pan and Yan, 2012). In this respect, it is thought that motion-based technologies' use will support learning by providing ease for the use and control for healthy and also disabled individuals. Colak, Yuksel, Sunguray and Gumus (2013) think that learning performance would increase as providing the involvement of students into education kinesthetically. It has been emphasized on how perceptional experiences of human beings would work, how machines would change their perception and how they would improve it, as being a point that requires to be considered (Reeves and Nass, 2000). Although many advantages of motion-based technologies have been mentioned in the literature about facilitating life of disabled individuals, limitations may be met to use this technology with its some aspects. The use of different factors which will arouse different feelings of individuals together increases the awareness of students on environment and makes them feel themselves in safe (Moll, Sallnäs, Pysander, Eklundh and Hellström, 2013). Accordingly, it can be thought that motion-based technologies are beneficial to increase and reinforce learning that it arouses more than one sense of individuals. But it should be paid attention not to cause cognitive load for the user as using any unnecessary factors together. Moreover, perceptional user interfaces which would refer to five senses should be developed in order to increase learning performance and usability. One of the limited aspects of Kinect technology is that it is restricted with perceiving 20 articulation points of a human. Moreover, if the act is not one that the users make as registered one, it is not perceived by the system (Tong, Zhou, Pan, and Yan, 2012; Suzen and Tasdelen, 2013). When it is considered especially for disabled individuals, it may not be possible to define each movement. This case reduces usability of the product. One of the limitations of Kinect is that this technology has a capacity of perceiving only to a certain distance (Hsu, 2011). When it is considered that movements of disabled individuals are restricted, this case has a great importance. When the results of examined researches are reviewed, motion-based technologies can facilitate life of individuals with special needs in many different handicapped groups and make their learning more efficient as they are designed to be appropriate for needs of them (Zeng, Miao and Weber, 2015; Suzen and Tasdelen, 2013). As we increase the interaction with the user, so the technology will provide benefit to the user in this scale (Preece, Rogers and Sharp, 2002). In this context, a deep needs analysis should be made to determine on what the users with special needs would need, before the production of this technology. Additionally, the interaction of individuals with special needs and these products should be followed and it should be paid attention on that this interaction is to be at maximum level.
