KIT724 Assignment3 -VR

1. Introduction

The application depends on VR technology to interact with museum scenarios. The goal of this application is to help museum visitors to use simulation museums to improve the user experience, then they can through the interaction to better understand the collections information. Meanwhile, visitors can use this application at home to have a good experience.

2. Description of the application 

The application uses VR technology to exhibit the museum collections. The application creates a museum simulation to help the Cleveland Museum to display the neck-amphora 3D virtual vase. Also, visitors can take Oculus Quest to join the application immersive museum to view the 3D virtual vases and information when they are at home, and they can interact with the collections when they are not in the museum. In addition, the application includes 3 main areas which are voice introduction area and vases dragging comparation area and different light vases comparation areas, and visitors can negative to each area to have a different interaction experience.

The application can help visitors to better understand collections in the simulation museum.   The collection's real size can be understood by this application.  Visitors only can view the computer screens size of museum collection when they visit the website. However, this application can display a similar scale of 3D model, and the light shadow can be displayed, and visitors can wear Oculus Quest to experience these features in simulation museum. Also, the virtual wall and floor are in the simulation museum, and walls display the information which is better than website description because the immersive experience can improve the collection comprehending. In addition, this application designs the voice and grab and light interaction areas to simulate the real museum, then visitors can negative to different areas to interact with the collections to improve understanding interest of the collections.

VR technology can improve the application usability and user experience. This application improves usability because VR technology can give us virtual hands and it can design 3D models such as walls and vases, then visitors can use the controllers to easily grab the 3D vases to view the details of collections. Also, VR improves the application simulated experience and immersive experience. VR is a simulated experience that users can base on pose tracking and 3D near-eye to have an immersive feel in the virtual world (Wikipedia). This application depends on VR to provide simulation museums, and visitors can have an immersive tour to interact with different collections. 

3.Interaction Design 

This application can help visitors to interact with the simulation museum collections at home.

The application designs 3 main interaction areas. The audio introduction area designs the audio interaction, and the shape comparation area includes the grab interaction, and the light comparation area includes the light button interaction. 

These interactions simulate the real museum audio introduction, and it can improve the usability because visitors can interact with different area to easily comprehend the vase information, and it can improve the immersive and simulation experience because audio feeing is same as the real world.

3.1 Storyboard

Audio interaction introduces the vase information. Visitors can listen to the vase introduction when they negative to the 3D model vases about 0.5 meters, and they are in the audio interaction area. Also, the neck-amphora introduction audio surrounds the number 1 vase (Cleveland Museum), and the vase history audio surrounds the number 3 vase (Mayfair Gallery Guides).

Grab interaction helps visitors interact with vases. Visitors can grab the vase to shape comparation area to compare the different vase shapes and patterns, and they can grab it to the light comparation area to compare the vases patten performance under the different light.

Light interaction helps visitors interact with light.  They can close the light button to turn on or turn off the red light in the light comparation area, then it will display the different vases pattern performance under the yellow and red light. This interaction will help visitors to realize the vases art design like under the real museum light.

4. Technical Development

The application uses the Oculus VR interface technology. The development includes the OVRPlayerController and OVRCameraRig. The OVRPlayerController can control the player movement during virtual reality, and the users bechaviour can be inherited (Meta Quest). Also, the OVRCameraRig is the camera rig is head-tracked stereoscopic camera rig of virtual reality, and it can provide the transform object to represent the tracking space of Oculus (Meta Quest). In addition, the application grab interaction uses the GrabManager and cube 3D models Rigidbody and Distance Grabbable technology, and it uses direct interaction such as finger poking and grab and rotation and move of the vase. Also, audio interaction uses the cube audio source function, and the Toggle Light Switch Behaviour is used for light button function.

5.Descriptions of 3D Models

5.1 Floor display cases are developed by the cube (image 5.1). They are on the floor to display the vases in different areas.

5.2 A-101 Vase is simulated the neck-amphora collection 3D models. Visitors can view the details of it.

5.3 A-102 Vase is simulated to the comparation vase. Visitors can drag it to compare with other collections.

5.4 Comparation area vases. They are changed shapes and colour by A-101 and A-102 Vases.

5.5 Light button is designed by the cube. Visitors can turn on or turn off the light.

5.6 Walls display the instruction for visitors. The museum different areas are created by them.

5.7 The roof is created the space of museum.
