Immersion and interaction in the 3D World
This section covers the ergonomics of immersive environments available to a user in such an environment, without using the interface of Accel VR Pilot or VSN player.
Creating an Immersive Sensation
Multiple elements work together to create a sensation of immersion for a user, including:
System calibration,
Shuttle position,
The use of tracking devices,
Appropriate preparation of the database to be used.
The user in an immersive environment is particularly sensitive to the position of his feet with regard to what he perceives as the ground in the virtual world. Make certain that his feet are on the same level as the virtual ground by positioning the exploration shuttle at the level of the ground.
Camera Animations
Camera animations, when they are available in your database, can be used to increase the immersive sensation in multiple ways. Depending on the experience you are aiming to create, different locks and camera animation options will be required.
Interaction Devices
Various devices improve the feeling of immersion by facilitating interaction with the immersive environment.
It is possible to add in the immersive system a device that lets you interact with the virtual world such as a Fly Stick or the Apex by VICON. These devices allow surfaces to be indicated with a virtual laser beam. Based on the active interaction mode, you can then use the device's buttons to interact with the indicated surface or object.
For this to work, three conditions must be met:
The model must have first been correctly configured in Patchwork 3D to be interactive.
A tracking system of the position and the orientation of the user's head.
One or two tracked interaction devices (left hand and right hand).
Tip
If your device is not tracked (e.g, a gamepad), please use the following path Manipulators > Device > Gamepad interactions from Advanced system settings. You can then set your interaction device to be 0.4m (40cm) below the head tracker, which will place it approximately as though it were held at the stomach-level by an adult user.
