User Interface
The Medicalholodeck user interface consists of the main control pad, the
object pad, the library panel and object markers.
1. Main control pad
The primary tool for navigating Medicalholodeck.
A
Library

to your desired location. Select again to disable the function.
C
4D Record
Creates immersive VR recordings. Select it with the trigger to start
recording and again to stop. The recording will then appear in the
RecordXR section of the library.
D
Team XR

G
Reset workspace
Clears all models and data from the workspaces.
H
Undo
Reverts your last action in the VR environment. Press repeatedly with
the trigger to undo multiple actions in order.
I
Redo
Restores previously undone actions. Press repeatedly with the trigger
to redo multiple actions in order.
J
Exit
Closes the application. Press it with the trigger to exit.
K
Capture a movie
Records your VR experience. Press it with the trigger to start and
again to stop. The video will be saved to your desktop. Only active on
the PC-VR mode. In standalone mode, press the Oculus button and open
the camera icon from the menu. Then select “Record Video” or “Take
Photo.”
L
Take a photo
Captures an image of your VR experience. Press it with the trigger to
take a photo. The screenshot will be saved to your desktop. Only
active on the PC-VR mode. In standalone mode, press the Oculus button
and open the camera icon from the menu. Then select “Record Video” or
“Take Photo.”
M
Handle
Repositions the panel. Select it with trigger and release to set it to
a new position.
2. Object pad
The object pad provides tools for manipulating, measuring, and
annotating datasets. It appears when a dataset is loaded from the
library.
A
Cutter
Enables precise cuts through the datasets. Select it with the right
trigger to activate the cutter on your left controller; press again to
switch it to the right. Move your hand into the model to see a live
cut. Pull the left trigger to fix the cut. To remove it, point your
laser at the red X. Use the marker’s cut visibility button to
show/hide cuts.
B
Laser
Turns on the laser, by default on your right controller. Use the laser
to point at interface elements, and press the trigger to select or
activate them.
C
Masking
Lets you focus on specific regions of a DICOM dataset by modifying
their visibility. Use your controller like a brush to 'paint' areas in
the 3D image - depending on the selected mode, the marked region will
be hidden, isolated, or highlighted. Pressing the mask button with the
trigger opens an additional panel and displays a red ball at your
controller’s fingertip. Masking requires a lot of rendering power so
it is recommended for PC-VR setup.
A
Mask size
Adjusts the red ball’s size. Use the slider to set the desired
width.
B
Mask mode
Allows switching between different masking modes.
- Isolate: keeps only the selected area visible
- Hide: hides parts of the dataset
- Highlight: visually emphasizes selected areas.
C
Mask mode
Restores masked areas. Point at the region, hold the trigger to
unmask, then release.
D
Mask channel
Let you organize and separate different masked areas within your
DICOM dataset. Switch channels to apply and manage varied masking
effects.
E
Mask volume
Shows the volume of the masked area on the selected channel.
D
Measure area
Allows area measurement. Press it with the trigger and a black cone
will appear at your controller’s fingertip. Press the trigger to place
points and outline your shape. To close the shape, move the cone near
the first point and press the trigger when the click to close the
shape prompt appears. The surface area will then be displayed in
square millimeters (mm²).
E
Measure distance
Allows distance measurement. Press it with the trigger and a black
cone will appear at your controller’s fingertip. Press the trigger to
set the start point, move to the endpoint, and press again to display
the distance in millimeters.
F
Delete
Removes objects like measurements, shapes, or drawings from the
workspace. A red X will appear on your controller - aim at the object
and press the trigger to delete it.
G
Scale
Resizes the active dataset. Press it with the trigger to enter scaling
mode. Move the controller up or down while holding the trigger to
adjust the size, then release the trigger to set it.
H
Move
Repositions the active dataset. Aim at the button, hold the trigger to
move the dataset, and release to place it.
I
Move backward
Adjusts the dataset’s distance. Aim at the button, hold the trigger
and move the controller up or down to bring it closer or farther while
holding the trigger. Release to set the position.
J
Frame rate
Displays performance in FPS, helping you monitor app smoothness.
K
Remove dataset
Deletes the active dataset. Press it with the trigger to remove it
from the scene.
L
Light on/off
Controls dataset lighting. Press the trigger to toggle the light on or
off. In Medical Imaging XR, lighting is available only in PC-VR mode
due to performance limitations.
M
Measure angle
Measures angles in VR. Press the trigger to set the angle’s vertex,
then define the two line endpoints. The angle in degrees appears
instantly once both lines are placed.
N
Draw
Enables drawing. Aim your laser at the button, press the trigger, and
move your controller to draw lines. An additional panel will appear.
Release the trigger to stop drawing.
A
Stroke width
Use the stroke width slider to adjust the line thickness. Aim your
laser, pull the trigger, and adjust the size to your preference.
B
Color
Select your desired color and press the trigger to update the
drawing tool's color.
O
Marker
Places visual markers in the scene. Aim your laser at the button,
press the trigger, and a colored arrow will appear at your
controller’s fingertip. Move it to the desired location and press the
trigger to place the marker.
P
Rotate horizontally
Rotates the active dataset left or right. Hold the trigger while
moving the controller horizontally, then release to set the angle.
R
Rotate vertically
Tilts the dataset up or down. Hold the trigger and move the controller
vertically, then release to set the angle.
S
Handle
Repositions the panel. Select it with trigger and release to set it to
a new position.
3. Library panel
The library panel is the main hub for accessing datasets. It includes
five sections: saved scenes, Medical Imaging XR, RecordXR and
Dissection Master and Anatomy Master.
A
Saved scenes
Captures and stores your current VR setup. This lets you resume
later with all settings and positions preserved.
A

with the trigger to restore it.
C
Delete
Removes a saved scene. Press the X in the top-right corner of the
scene’s button with the trigger to delete it.
B
Medical Imaging XR
It is section is for managing medical imaging data - upload, view in
VR, and adjust DICOM windowing with ease. For full guidance, see the
Medical Imaging XR manual.
C
RecordXR
A dedicated hub for spatial recordings - review, replay, delete, or
export them as RXR files. For details, see the
RecordXR manual.
D
Dissection Master XR
It is a virtual dissection lab with layered, annotated models from
real human bodies. Press the model with the trigger to load a
dataset into VR. For full guidance, see the
Dissection Master manual.
E
Anatomy Master 2
It is a 3D human anatomy atlas in virtual reality, featuring
detailed male and female models. Press a model with the trigger to
load it into VR. For full guidance, see the
Anatomy Master manual.
4. Object marker
In Medicalholodeck, each loaded dataset is marked by an object
marker on the floor - blue for active, grey for inactive.
A
Center
Allows moving the model around the workspace. To do so, click and
hold on it to select. Then point the laser to the desired location
and release it to drop in the new position.
B
Lock
Locks the model in its actual position
C
Delete
Deletes the model from workspace.
D
Groups
Allows grouping of data sets and overlaying them for comparison.
Particularly useful for analyzing different types of data from a
single patient.
E

Shows or hides the placed cuts.
5. Lighting
In Medicalholodeck, lighting can be toggled and angled to enhance
model visibility. It's visualized by a yellow sun and marker.
Light
A yellow sun represents the lighting and appears above the scene by
default. Aim and hold the trigger to move it and adjust the light
angle.
Light marker
This tool lets you move the lighting and toggle it on or off. When
off, the sun and marker turn blue. Aim at the marker and hold the
trigger to move it. Press the on/off button to toggle lighting.

8. Low framerate screen
When the frame rate drops below 10 FPS, a warning screen appears
to protect your device from crashing or overheating. You then can
choose to continue or remove all data to reduce load. After that
it is recommended to adjust quality settings to improve
performance. See
