In our final year design project, we worked on 'Studies in application of Augmented Reality in Chemistry E-Learning courses' while taking Solid States as our case-study topic. The projects was carried out in two parts: (i) Design and Prototyping, and (ii) Comparative Study



Design and Prototyping
Teachers interviews were conducted to validate the need of 3d visualizations and AR in Solid States chapter and decide upon the content of the initial version of application. On the basis of this study, design suggestions to be considered while designing AR based solutions in the field of solid state chemistry are proposed. Incorporating these suggestions, we then conceptualized and developed an AR application for mobile and tablet devices using Unity3D in conjunction with Qualcome Vuforia AR SDK. 3d models were created in sketchup which were imported in Unity afterwards. This application uses standard XII NCERT textbook images as markers/reference to augment dynamic 3-dimensional content. Its initial feedback session with students indicated its acceptance.
  
Process Followed
Augmented Chemistry 3d models onto NCERT book pages






Comparative Study
The next phase was focused on testing this application through a comparative study with existing e-learning style web and mouse based 3d navigation tool. Aim of the study was to identify strengths and weaknesses of the AR based tool. These two were compared on different parameters: content learnability (through self-made quiz), effect on spatial rotation skills(PSVT: R) and technology acceptance (TAM questionnaire). Only aid in spatial rotation was found to significantly better (both accuracy and time taken) for web-based tool. From our learning of this study, we proposed guidelines which one should consider while designing interactions, interface and instructions etc. for such AR based pedagogical tool.
