In the past decade, Augmented Reality (AR) has been applied in several professional practice areas, including but not limited to autism therapy. AR supplies virtual information to the visual perceptions of users, giving the user new tools to ensure that knowledge for many processes and in many environments are comprehended efficiently. Usually, AR applications depend on virtual reality headset (VR-box) to overlay virtual objects and text on the surrounding environment of the user.People with autism spectrum condition (ASC) especially children are often found lacking in social interaction, including facial expres-sion and understanding of other minds which make social communication more difficult for them. This paper aims to use AR system to assist children with (ASC) in better understanding facial expressions by overlaying suggested 3d objects over the physical environment. Results of AR treatment found higher engagement and more effective compare to a non-AR system.This paper utilizes Vuforia to create an AR environment for the treatment of children with ASC. Vuforia is a software development kit that provides AR capabilities to smartphone devices.

In general, most of the current augmented reality systems can combine 3D virtual scenes with live reality, and users usually interact with 3D objects of the augmented reality (AR) system through image recognition. Although the image-recognition technology has matured enough to allow users to interact with the system, the interaction process is usually limited by the number of patterns used to identify the image. It is not convenient to handle. To provide a more flexible interactive manipulation mode, this study imports the speech-recognition mechanism that allows users to operate 3D objects in an AR system simply by speech. In terms of implementation, the program uses Unity3D as the main development environment and the AR e-Desk as the main development platform. The AR e-Desk interacts through the identification mechanism of the reacTIVision and its markers. We use Unity3D to build the required 3D virtual scenes and objects in the AR e-Desk and import the Google Cloud Speech suite to the AR e-Desk system to develop the speech-interaction mechanism. Then, the intelligent AR system is developed.

Difficulty in understanding the feelings and behavior of other people is considered one of the main symptoms of autism. Computer technology has increasingly been used in interventions with Autism Spectrum Disorder (ASD), especially augmented reality, to either treat or alleviate ASD symptomatology. Augmented reality is an engaging type of technology that helps children interact easily and understand and remember information, and it is not limited to one age group or level of education. This study utilized AR to display faces with six different basic facial expressions—happiness, sadness, surprise, fear, disgust, and anger—to help children to recognize facial features and associate facial expressions with a simultaneous human condition. The most important point of this system is that children can interact with the system in a friendly and safe way. Additionally, our results showed the system enhanced social interactions, talking, and facial expressions for both autistic and typical children. Therefore, AR might have a significant upcoming role in talking about the therapeutic necessities of children with ASD. This paper presents evidence for the feasibility of one of the specialized AR systems.

This paper presents a new method for public and blind watermarking of 3D objects and hiding information of various types in virtual reality and augmented reality environments. In particular, the virtual scene is transformed to a tree-based model using constructive solid geometry (CSG). The tree of the virtual 3D objects is composed of nodes and leafs. Each tree node contains a set operator (union, intersection or difference) whereas the tree leafs consist of geometric primitives such as spheres, cylinders and cubes. The proposed method allows embedding invisible watermarks that can hide different security information types. The proposed method ensures unlimited capacity and absolute invisibility of the hidden information with robustness to affine transformations. Thanks to these unique properties, it is possible to implement all the security infrastructures needed for a virtual and augmented reality system. Finally, the performances of the proposed method are shown using 3D models of different types and scenes.
