Brain injury such as traumatic brain injury (TBI) and stroke is the major cause of long-term disabilities in many countries. The increasing rate of brain damaged victims and the heterogeneity of impairments decrease rehabilitation effectiveness and competence resulting in higher cost of rehabilitation treatment. On the other hand, traditional rehabilitation exercises are boring, thus leading patients to neglect the prescribed exercises required for recovery. Therefore, we propose game-based approach to address these problems. This paper presents a rehabilitation gaming system (RGS) for cognitive rehabilitation. The RGS is developed based on a proposed conceptual framework which has also been presented in this paper.

Recent studies have found that imbalanced motor skills (hand-eye coordination) among autism spectrum disorder (ASD) or autistic children cause lower efficiency in daily routines. Autistic children need long-term rehabilitation programs to improve their abilities. However, problems with a lack of motivation to participate in conventional therapy and the high cost of therapy sessions arise over time. Autism children are necessary to do repetitive activities every time through therapy sessions. Repetitive activities cause children having less interest to participate in ongoing therapy sessions. Besides, the therapy process usually requires a long time to be implemented that cause the relatively high cost had to be paid by the patient's family. The use of technology is seen as more effective and less annoying for a child with autism. However, the use of games technology requires the gamer to hold a game controller. Proposals for motion-based toothless games using NUI technology, such as the Kinect Xbox 360, to be used in rehabilitation are exciting for patients, but the design elements do not meet the requirements of autistic people. Hence, this research proposes a Kinect game based on design elements for autistic rehabilitation. The objective of this research is to identify a symptom of eye-hand coordination problem and develop a severe game using Kinect technology as the solution to the problem faced by autism children. This technology provides a low-budget solution costs of therapy and games base on the 3D sensor without the use of control equipment which must behold or touch by hand. Moreover, Kinect does not need a controller or additional body-worn attachment during play time. A game prototype was developed and measured, and evaluation resulted in positive feedback from the user and therapists, thus meeting the objective of this study.

Natural User Interface (NUI) is a new approach that has become increasingly popular in Human-Computer Interaction (HCI). The use of this technology is widely used in almost all sectors, including the field of education. In recent years, there are a lot of educational games using NUI technology in the market such as Kinect game. Kinect is a sensor that can recognize body movements, postures, and voices in three dimensions. It enables users to control and interact with game without the need of using game controller. However, the contents of most existing Kinect games do not follow the standard curriculum in classroom, thus making it do not fully achieve the learning objectives. Hence, this research proposes a design model as a guideline in designing educational game using NUI. A prototype has been developed as one of the objectives in this study. The prototype is based on proposed model to ensure and assess the effectiveness of the model. The outcomes of this study conclude that the proposed model contributed to the design method for the development of the educational game using NUI. Furthermore, evaluation results of the prototype show a good response from participant and in line with the standard curriculum.
