“…One of the characteristics of usability is learnability, or the ability to learn quickly. User-friendliness is described in previous studies [11,12] as the ease with which a user may start and discover new aspects of the system. The ease with which a user can use a product or system (learnability) shows how simple it is for the user to use the product or system and whether the user can readily understand how to use it.…”

The flipped classroom model enables students to acquire fundamental knowledge outside of class time; thus, include reading materials or video lectures. This will be able to free up class time for knowledge application, student engagement in active learning, and higher-order thinking. The flipped classroom model is increasingly being adopted in competency-based medical education. However, the potential of flipped classrooms for enhancing medical education has not yet been proven and it poses a major challenge to students who have not mastered self-regulated learning strategies. Thus, they may not be able to understand the information presented in the course materials or to strategically use learning resources outside of class. In this project, we have created a mobile augmented reality (AR) application for students studying anatomy to help them grasp the idea of the AR flipped classroom. Students were instructed to use the same three mobile augmented reality (MAR) applications with different design and approach. The three types of MAR applications are — those with markers and notes on printed notebooks (BARA1), those with markers and notes are on a website (BARA2), and those with all notes in the MAR application and the marker are a tangible 3D object (BARA3). From the series of experiment, we found out that most students favour the BARA3, meanwhile the medical lecturers essentially prefer the BARA1. In this research three things have been considered: interface design, the usefulness of Augmented Reality (AR), technical problems with the use of AR applications, and educators training on the use of AR applications. Without a well-designed interface and guidance for the students, AR technology can be too complicated to use, especially for those who are not familiar with the technology.

In this paper, we introduce a bare-hand interaction method for controlling an augmented virtual character. Our method is utilizing a dynamic hierarchical structure of virtual buttons on the natural marker of the environment. Unlike the existing virtual button method, the proposed method can be used to select a very fine level. This method is adequate for controlling an augmented virtual character with a users' various intentions. We implemented several examples of manipulating an augmented virtual character such as guiding the character, selecting part of the character, and selecting a target object for the character. We also compared the performance of full arrangement and dynamic hierarchical arrangement of virtual buttons. Our method outperforms the full arrangement method, especially in the low index of difficulty. In the user study with 15 participants, the users responded that the proposed method was significantly better than the existing full arrangement method regarding efficiency and satisfaction in the case of the fine level selection.

“…Also, use of another phone as an external hardware device as controller have been proposed in few researches [2,7,10] these controller phones are used with HMD device or another Mobile phone, these controller phones allow to use additional sensor and UI interface but such implementation will not get to large audience. there some interaction technique such as touch screen-based gesture which makes the users screen cluttered with UI elements or hand gesture should that needs additional depth sensor for it to work properly, Also for Virtual based controller used of Virtual buttons [1,4,8] but are not so interaction and used for showing some few animations on a same image target this can be used with multiple image target to enhance the interactive experience. This technology has various Application area like, manufacturing, military, medical, education, gaming, etc.…”

Mobile phones have made the Augmented Reality technology easily available to large audience and people are developing applications for it but the interaction with mobile AR is limited by touchscreen gesture, hand-based gesture can be used but it needs additional sensors like depth sensor and better processing power to work properly and lower end mobile phone devices cannot handle it and also external hardware can be build but around it but it adds to additional cost and is also not affordable to everyone. In this project a prototype application is developed to demonstrate the use of image targets to design a virtual controller that can be used to interact with AR content and implement basic tasks such as touching and moving virtual objects available in the AR space with the help of virtual controller and further the paper discusses about the benefits and drawbacks of such implementation and its future usage.
