Introduction: Virtual Reality (VR) has been found useful for numerous rehabilitation applications, but has some intrinsic constraints such as the need for a visuospatial transformation when guiding movements. Augmented Reality (AR) is a new approach to human-computer interaction that enables patients to interact directly with virtual objects. The current study compared AR and VR in a stroke rehabilitation setting. METHODS: The Fruit Ninja game simulates a rehab setting by having subjects perform repeated goal-directed wrist/hand reaching tasks. Subjects held a cup-shaped color-marker in the paretic hand, then reached for a virtual fruit target that sliced in 2 when reached. This game was implemented in both AR and VR settings, with identical movement demands across the two. The target plus real-time visual feedback on hand movements were provided by a computer monitor in VR, and by a projection onto a tabletop in AR. After undergoing baseline assessments (arm motor Fugl-Meyer scale (FMA) and Box and Blocks (B&B)), 10 patients with hemiparetic stroke >6 mo prior and age >18 yr played three 1-min rounds each of the AR and VR games; 4 other subjects who were unable to hold the color-marker object were excluded from current analysis. RESULTS: Of the 10 patients, age = 59±10 yr (mean±SD), FMA score = 57±11 (range 31-66), Hand/Wrist FMA subscore = 22±3 (range 15-24), and B&B score = 41±13 (range 16-58). When playing the exact same Fruit Ninja game, all 10 patients scored significantly (p<0.0001) higher in the AR setting (60±9 targets, range 48-78) as compared to the VR setting (48±8 targets, range 37-64 setting. Also, AR scores were stronger correlates of FM Hand/Wrist (rho=0.68, p<0.04) and B&B scores (rho=0.70, p<0.03) than were VR scores. CONCLUSIONS: This study shows promising results with use of Augmented Reality in a patient-computer interface. Results also suggest advantages as compared to use of a Virtual Reality approach, possibly due to the fact that moving the hand requires a visuospatial transform in the VR setting but not in the AR setting. Compared to VR, AR scores were higher and correlated better with clinical scores, suggesting great potential for the use of Augmented Reality in a patient-computer interface during stroke rehabilitation.

In this paper, rehabilitation tools are proposed and implemented to assist patients with stroke and body dysfunction via auxiliary physical activity. By integrating the entertainment of games and the needs of rehabilitation and utilizing motor assessment scale (MAS) as the building blocks, we propose a game system developed for assessment of stroke rehabilitation by using augmented reality (AR) technology. By means of application of AR Markers and based on related parameters of Wii remotes, various assessment games have been implemented, and vivid pictures can be presented to users via a head-mounted display by seamless combination of real environment and virtual objects. This game system takes various assessment scales into consideration, and each scale is specifically designed and individually integrated to enable the relevant capacity for assessment of motor functions. According to the experimental results, the accuracy rate of the users in successfully following the game steps is 91.2%, and the accuracy rate of the system in assessing the MAS categories is as high as 94.6%, which confirms the feasibility of our proposed and implemented rehabilitation game system.

Augmented reality is defined as the technology in which virtual objects are blended with the real world and also interact with each other. Although augmented reality applications are used in many areas, the most important of these areas is the field of education. AR technology allows the combination of real objects and virtual information in order to increase students’ interaction with physical environments and facilitate their learning. Developing technology enables students to learn complex topics in a fun and easy way through virtual reality devices. Students interact with objects in the virtual environment and can learn more about it. For example; by organizing digital tours to a museum or zoo in a completely different country, lessons can be taught in the company of a teacher as if they were there at that moment. In the light of all these, this study is a compilation study. In this context, augmented reality technologies were introduced and attention was drawn to their use in different fields of education with their examples. As a suggestion at the end of the study, it was emphasized that the prepared sections should be carefully read by the educators and put into practice in their lessons. In addition it was also pointed out that it should be preferred in order to communicate effectively with students by interacting in real time, especially during the pandemic process.

The concept of education for children is important. The aspects that must be considered are methods and learning media. In this research innovative and alternative learning media are made to understand fruits for children with Augmented Reality (AR). Augmented Reality (AR) in principle is a technology that is able to combine two-dimensional or three-dimensional virtual objects into a real environment and then project it. This learning media combines picture cards and virtual reality. Markers contained on picture cards will be captured by the mobile device camera, processed and will 3D animated pieces appear on the mobile screen in realtime. By using the concept of combining real world, real images on cards and virtual, applications can stimulate imagination and sense of desire in children and motivation to learn more and more. 3D fruit estimation created using the 3D Blender application and the Augmented Rea process lity is made using Unity and the Vuforia SDK library. The application of fruit recognition has been applied to several child respondents and has been tested on several types and brands of Android-based mobile phones. Based on research trials, 86% of 30 respondents stated that the application which was developed very effectively as a medium for the introduction of fruits.

In recent years, the assistive technologies and stroke rehabilitation methods have been empowered by the use of virtual reality environments and the facilities offered by brain computer interface systems and functional electrical stimulators. In this paper, a therapy system for stroke rehabilitation based on these revolutionary techniques is presented. Using a virtual reality Oculus Rift device, the proposed system ushers the patient in a virtual scenario where a virtual therapist coordinates the exercises aimed at restoring brain function. The electrical stimulator helps the patient to perform rehabilitation exercises and the brain computer interface system and an electrooculography device are used to determine if the exercises are executed properly. Laboratory tests on healthy people led to system validation from technical point of view. The clinical tests are in progress, but the preliminary results of the clinical tests have highlighted the good satisfaction degree of patients, the quick accommodation with the proposed therapy, and rapid progress for each user rehabilitation.
