Introduction

Use zView to share a zSpace session. Normally, only the person at the zSpace can see the application in stereoscopic 3D. zView projects the user’s experience onto a screen or a second monitor. You can use zView to share the application in real time, record the zSpace session, or both.

Modes

zView provides two different modes:

  • Augmented Reality View shows the application from a fixed viewpoint, without head tracking. This mode requires a camera.

  • Standard View shows the application with head tracking. Use this view to demonstrate how the application adjusts the viewpoint as the user’s head moves. This mode does not require a camera.

Requirements

zView has minimum requirements for Standard view and additional requirements for Augmented Reality view.

Standard View requirements:

  • zSpace System Software
  • zSpace 200: Version 4.0 or later
  • zSpace 300: Version 5.0 or later
  • zView-enabled application
  • A second display for the zView application window

Augmented Reality View additional requirements:

  • A webcam that supports HD resolutions (1280x720 or 1920x1080) at 15 frames per second (FPS) or higher. zView works well using the Logitech C920 and Microsoft LifeCam Pro webcams.
  • A zSpace camera mount or a tripod.

You can purchase a zView kit from zSpace that includes a webcam and a camera mount to attach the webcam to the zSpace display.

The zSpace application you want to view must be enabled for zView. All zSpace STEM applications are enabled and have zView controls embedded in them. If you are developing your own application, you can enable it using the zView Unity plug-in.

Compatible zSpace Applications

zView works with the following zSpace applications. More are applications are being added:

  • Newton’s Park
  • Franklin’s Lab
  • Studio
  • Euclid’s Shapes

Set Up zView

zView runs on the same hardware required for zSpace applications. You must attach a second monitor to use zView. You need a webcam to share and record zSpace sessions.

Connect a Second Display

You can connect the zSpace computer to a second monitor, a projection screen, or a TV. For more information, see Display Configurations - Managing Multiple Displays at zSpace Support.

Set Up the Camera

If you are only using the Standard View, you can skip this section.

Refer to the documents for your system when setting up the tripod or camera and mounting kit. Here is additional information on connecting the zView armature and camera.

Plug the webcam USB cable into your PC. On the zSpace 300, use the USB 2.0 port on the back of the zSpace.

Note: On many PCs, the webcam functions best in a USB 2.0 port instead of a USB 3.0 port.

Configure zView

When you start zView, if it does not appear on your secondary display, drag the zView window to that display.

  • If you are using Standard View, you do not need to configure zView.
  • If you are running zView in Augmented Reality View, which includes sharing the head-tracked experience, you must configure zView to work with your camera. You can configure zView from the Setup menu.

Augmented Reality View

Make adjustments to the camera position during Setup. This includes making sure that the camera captures the user’s expression, if desired, and that lighting does not cause a glare on the zSpace. If you adjust the camera later, you must run Setup again.

Note: Make sure the camera is connected to the zSpace and facing the zSpace display.

Follow these steps to run Setup. Additionally, we have a video which walks a user through the camera setup process. The camera setup is about 2 minutes into the video.

  1. Start zView.
  2. Click image28.jpg Setup to start the configuration.
  3. From the USB Camera Setup dialog box, select your USB webcam. Choose the recommended resolution.
  4. Click Next to continue.
  5. zView Display Detection dialog box appears and is semi-transparent. image29.jpg

    Six test patterns appear on the zSpace. Check the zView window. At least two markers must be outlined in red before you can continue. zView also outlines the zSpace screen in red.

  6. For the best results, adjust the camera until zView detects all six markers and the outline turns green, then click Next
    Note: If zView cannot detect the display, make sure the camera view includes all four corners of the zSpace display. Next, try lowering or adjusting the lights to avoid glare on the camera and zSpace.
  7. Click Finish.

Adjust the Overlay

You can adjust how the zView-enabled application displays in Augmented Reality View.

Complete the following steps:

  1. Open a compatible application in zView.
  2. When the application appears in the zView window, select Tools > Show Display Bounds. This makes it easier to check the fit of the zSpace display in zView.
  3. In zView, select Tools > Adjust Overlay.
  4. If the application does not fit in the zView window correctly, make the following adjustments:
    • To move the display right or left, enter a positive or negative number in the X Offset text box.
    • To move the display up or down, enter a positive or negative number in the Y Offset text box.
    • To adjust the size of the display, enter the percentage to scale the display as a decimal number in the Scale field.

      The following figure shows an overlay out of position.

      image30.jpg

      The following figure shows an overlay correctly adjusted.

      image31.jpg

  5. When the overlay is correctly adjusted, hide the display bounds by clearing the Tools > Show Display Bounds menu option.
  6. Click OK.

When you run zView again, the system prompts you to reuse the current settings or run the Setup Wizard again.

If the application you are running includes zView controls, the next time you run the application you can launch zView from within the application. However, if you move the camera you must repeat these configuration steps.

When you are done configuring zView, you can share or record a zSpace session. See the next section for more information.

Share and Record zSpace Sessions

When you are done configuring the system as described in Configure zView, you can share and record zSpace sessions.

Share a zSpace Session

Using zView, you can share a zSpace session in real time. To share a zSpace session, start zView then launch your zSpace application.

Tip: The zSpace STEM applications are integrated with zView. Once you complete configuration, you can start zView by clicking on the zView icon in the STEM application’s Control Bar.

If needed, use the following steps to fine-tune the zSpace display in zView.

  1. Make sure you can see your zSpace session in zView. Move the zView window from the zSpace display to your second monitor if necessary.
  2. Choose Standard View or Augmented Reality View as described in Configure zView. You must have a webcam for Augmented Reality View.
  3. Set zView to full-screen mode, if desired, using the toolbar button or by pressing F11. Full-screen mode is recommended if you are projecting onto a large screen.
  4. For Augmented Reality View only, adjust the overlay as described in the Adjust the Overlay section.
  5. When the zSpace display is correct, choose Share Screen from the toolbar.

Record a zSpace Session

Using zView, you can record a zSpace session. You can record in either Standard View or Augmented Reality View.

Tip: The zSpace STEM applications are integrated with zView. Once you complete configuration, you can start zView by clicking on the zView icon in the STEM application’s Control Bar.

Record your session as follows:

  1. Make sure you have turned off the display bounds by deselecting the Tools > Show Display Bounds menu option.
  2. Select Settings > Video Quality from the toolbar to adjust the quality of your recording. A higher quality results in a larger video file.
  3. To start recording, select the Start button from the toolbar. You can also use the keyboard shortcut Ctrl R.

    When you start recording the Record button is replaced by the Stop button.

  4. You can select the Pause button from the toolbar to pause while recording.
  5. To stop recording, select the Stop button. You can also use the keyboard shortcut Ctrl T.
  6. By default the video is saved in the Users\Public\Public Videos folder. The system prompts you for a file name when you stop recording.
Note: Choose Cancel to discard the video without saving.
