Augmented reality and virtual reality in the educational sector are rising more than ever. While there are challenges AR and VR are facing like the question of cost, effectiveness and health both educator and student benefit from these new technologies which bring interactivity and are currently developing and expanding their availability.
AR and VR in education provide the learner or student with a variety of functionalities at one time and bring a greater experience through immersion and overall visualization. A lesson does not consist of listening and looking at something because with these technologies students experience a topic and participate in a given subject. Travelling through cities, showing the anatomy of a human body or technical systems excite the students and are more memorable, tangible, understandable and learnable after all.
Students can see 3D objects and disassemble them instead of seeing a single 2D picture which is limited to viewing just one perspective and does not include the option to interact with the object itself. In general AR accelerates a higher preoccupation with the topic. Information can be absorbed better if it is perceived visually and students learn in a more efficient way especially if 3D models are designed appealing and they are engaged in the process.
Looking on the possibility of showing the signing gesture-movement of the visual language learners might also select specific parts of the body to concentrate on the movement of only one hand or the specific facial expression (like disassembling an engine into small pieces). To oversee every single aspect in the signing movement which comes within a short time the selection of specific parts, the possibility to slow down the movement and viewing it from the side would benefit the learning process. The complex signs which work through the movement of the whole upper body with fingers, hands, arms, shoulders, torso, head and the face could be understood and learned more easily and intuitive. This is more effective and understandable than reviewing 2D videos or pictures taken from one perspective which are aligned to show the whole complexity of a sign, phrase or sentence.
