The next generation of 3-D video will be based on technology, where a viewer will be able to get different views of the scene by moving her head or walking around the display. This will involve dynamic depth cues that result from the viewer’s own motion, not just from the motion of objects in the scene.

Virtual Reality Technology

Explanation:

Virtual reality is a simulation based computer technology which imitates the real world and provides real life like experience. One of the key  applications of virtual reality is 3D video games where users use VR headsets and get immersed into the world of simulated reality. VR technology also incorporates sensory inputs from the user, their physical movement gets translated in real time and they can move around and interact with various features. They can also sense dynamic depth which provides a real world experience.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
