III. AUGMENTED REALITY
AR combines the real and virtual worlds and complements the real world in real time with computer-generated virtual objects. According to one of the most widely used definitions, AR has three main requirements: the combination of real and virtual objects in the real environment, the coordination of real and virtual objects with each other, and the real-time interaction. It is a technology that we have. You can combine real and virtual element-like potential classifications. The continuum moves from a completely realistic environment to a completely virtual environment.
DG2: Defense Grid 2 and Defense Grid 2:
Enhanced VR Edition
Defense Grid 2 is a tower defense strategy game developed by Hidden Path Entertainment. Players view the game from a top-down perspective while acting as an army commander defending the base from alien waves. Over time, players acquire resources by killing aliens. The resources will be used to build a tower that shoots aliens as they approach the base. There are different types of turrets, such as cannons and laser turrets, each with different strengths and weaknesses. In addition, there are various aliens. Some are very slow and difficult to kill, others are weak and fast. You can upgrade your tower to increase its strength and customize the path of your aliens. For example, at one level it gives players the opportunity to place towers to divert aliens, and at another level it gives players space to build towers that determine the diversions of aliens.
Participants played the game on a 24-inch computer monitor and a consumer version of the Oculus Rift VR headset. The Oculus Rift is a VR headset with features such as 3D, position tracking, accelerometer, and gyroscope (Nield, 2016). Oculus Rift provides high graphic fidelity to create more attractive virtual environments. Players can use their head movements to look around and immerse themselves in a virtual world. DG2: Defense Grid 2 was a monitor-played game, and Defense Grid 2: EnhancedVR Edition was a version played on Oculus Rift.
Defense Grid 2 was chosen as the game for this study because the game has a VR version and a non-VR version.
The game version of is almost the same, except for minor changes to the VR edition UI. For example, in the VR edition, the tower build menu was displayed as a grid with icons for each tower type above the selected tower location. In the monitor version, a turret construction menu with details on turret attack damage, range, and rate of fire was displayed on the left side of the screen. The similarity between the two versions was the reason for choosing it as a game. This is because some games in the VR version only switch to motion control or don't have enough similarity to compare. I played both versions of the game using my Xbox one controller.
Those student are participants contest providing consent form for video game Defense Grid 2 using oculus Rift or desktop computer. The first portion completed the game player are guess desktop computer they continued to play second defense grid 2 completed the game again oculus Rift. The within design an experiment was chosen to provide a comparison between two version of the game.
The participant would continue play instead of restarting from the starting point game that make them easier and boring also and affect satisfaction also but complete game. Taken 2 hour rest for game and student then after played that game.The game exciting
Add new mission more and increase weapons and student made satisfaction and enjoy game.
