Oculus Rift Plug-in can also cooperate with HMD. Though basic functions that enable the immersion to 3D space is the same as HTC VIVE, a large difference between HTC VIVE and Oculus Rift is the size of immersion range. While Oculus Rift provides the area of about 2.4 m at diagonal line, HTC VIVE does up to about 5 m. That is, you can have a VR experience in wider range with HTC VIVE than Oculus Rift.

▲ Required spec for HTC VIVE

▲ View seen with HMD (display by Steam VR)

1. Model display at the position of controller
   A 3D model you set is shown on the display and it moves according to the motion of the controller. It is useful to see the scale of motion in VR space since a model can be displayed at the position of sensor too.


2. Function to move the point of view
   The reference point of view can be moved with the controller buttons. The VIVE provides a playing space of 5m in the diagonal, and moving the reference viewpoint lets users move around a wider VR environment.


3. Scenario / Script menu
   In the case of the previous version, users had to take off the HMD temporarily and operate the software to play scenarios and scripts. In this version, users can display the menu and execute them from a controller.

▲ Operation menu of VIVE plug-in

Event function linked with the VIVE device has been added to the scenario function. The activation and invalidation of the connection with HMD, reset view, and controller vibration setting are available. Since users can select which device vibrates, it is possible to vibrate the device at the arbitrary timing or to switch the HMD connection during driving in scenario.

▲ Scenario event setting

In addition to by operating buttons and pad on controller, users can shift scenario events by using the trigger for the collision between models displayed in UC-win/Road and ones displayed on controller, tracker, HMD, or sensor. This function allows users to ride on the vehicle when the controller buttons are pressed, when the controller model contacted with the vehicle model, etc.

▲ Setting of scenario trigger

The VIVE tracker is a device that imports objects in VR space as an object that is motion-tracked. Different from the controller, the VIVE tracker is used by attaching on body or object.

Set 3D model is displayed at the position of the VIVE tracker and moves along the motion of tracker. Several trackers can be recognized at once. It can be used for the work simulation by attaching to tools at construction sites, for the motion capture by attaching to hand or leg, and for other usages.
