The next partner playing VR games should always be able to see 3DoF and 6DoF, so what do they really mean?
The so-called DOF is the abbreviation of the English degree of free, Chinese translated as: degrees of freedom. Substituting it into a VR game console, we can simply understand the degree to which players can move freely in VR games.
1, 3DoF, that is, can do a translation movement on 3 coordinate axes means that players can simply, forward/backward, up/down, and left/right in the VR game console.
In the VR experience of 3DOF, all the base point of observation comes from the perspective of the head, and the user is like a camera that can be rotated arbitrarily on a pole.
Whether you are a strong man or a petite girl, your perspective will be forcibly pulled back to the preset height - 3DOF, all beings are equal.
3DOF's head interaction is mainly through ray casting. The principle is that a beam of radiation is shot from the center of the calibrated field of view directly in front of it, and the rays intersect with the interface in space.
2, 6DoF, that is, in addition to 3DoF plus 3 kinds of rotational motion
Players can do three kinds of rotational movements in VR consoles: Roll, Pitch, and Yaw. Therefore, 6DoF equals 3 types of translational motion + 3 types of rotational motion.
6DOF is 6 degrees of freedom, in addition to the ability to rotate on the X, Y, Z three axes, but also has the ability to move on the X, Y, Z three axes. In this way, 6DOF VR devices can simulate almost all head dynamics. Moreover, using the displacement data, it is also possible to calibrate the user's height.
In 6DOF, in addition to environmental perception, the main role of the headset is to enhance many active behaviors, such as: micro-movements (tilting the head, shrinking the neck, leaning forward halfway forward, etc.), the main body movement (can walk, jump, squat or even lie down).
At present, the conventional handle of the 6DOF has an infrared emitter embedded in it, and although the key design is also very similar, the grip and key-value mapping are very different.
The grip of the entire handle is more ergonomic, using dozens of sensors + hand fixation structure, and more emphasis on guiding users to take natural gestures in the real world such as grasping and finger touch. The purpose is to further encourage users to forget the handle, release their hands as much as they want, and use their fingers flexibly.
Do you know both 3DoF and 6DoF for VR consoles?
