Google released Daydream Elements at this year’s I/O. It is basically a set of best practices and reusable code for some of the most fundamental things that one can do in VR. Some of the things include walking around and interacting with the environment.
Let’s have a look at few key elements-
1. Tunneling effect
When it comes to implementing VR in motion, one of a major problem that occurs is that Motion causes some people to feel uncomfortable in VR. The is because of the change in the field of vision and difference between the virtual world and the real world. Tunneling Element for Virtual Reality can be used during rotation or while virtually moving around. In a study, Google found out that the use of a stable grid was the most effective at reducing discomfort. Google also used this technology in Earth VR.
2. Chase Camera effect
Most of the current day VR use includes games. We often find a case where we have to chase a certain thing or follow some character in the game. If that happens automatically then it causes discomfort to users. Chase Camera Element emphasizes control and expectations. The users can determine their target destination with a touchpad click so that moving in that direction feels natural. It also avoids automatic camera rotation. Users can also manually rotate the camera with the touchpad but the Tunneling Element will turn on during the rotation.
3. Exciting Teleportation feature
Teleportation allows users to easily explore a large virtual environment. When any user touches the touchpad, an arc is drawn to the teleportation target. The users just have to click that arc to get teleported to that location. You might think that the instant switch will require some time delay to get our surrounding right but it is not so. Users can avoid this by using fast wrap effect which quickly flies to a new location.
4. New Rendering technology
There are many more elements like the swipe menu or the click menu. The ultimate goal of Google Daydream elements is to make VR design easily available to developers who want to develop creative VR content.
