Using the Leap Motion Visualizer
This article describes the Leap Motion Visualizer application that lets you view motion tracking data generated by the Leap Motion Controller.
The Visualizer application displays finger tip tracking data and is a good way to get a feel for the data produced by the Leap. Start the Visualizer from the Leap Motion menu on the Windows Taskbar or Mac Finder bar.
Now move your hands in the Leap Motion controller's field of view. You should see your fingers represented as colored pens with trails following your finger tip locations.
You can control the Visualizer with key commands. Press H twice to display the available commands.
- Esc — Quit the Visualizer.
- H — Display the Visualizer framerate, Leap Motion framerate, and key commands.
- S — Switch between windowed mode and fullscreen.
- Z — Flip the positive and negative directions of the z-axis.
- G — Toggle the coordinate grid.
- J — Switch between black and blue or white and gray (Jony mode).
- I — Toggle interpolation of finger tip trails.
- Y — Toggle artistic drawing of finger tip trails.
- L — Display tracking info, including labeled axes, field of view, finger tip coordinates, and processing latency.
- T — Toggles the display of fingers and tools between lines and cylinders. In cylinder mode, the cylinders are colored differently depending on whether the Leap Motion software recognizes the object as a tool or a finger. In line mode, a color is randomly assigned to each object when it is first recognized.
- N — Cycles the display of palm tracking data between fingers only, palm plane, and hand ball modes.
- O — Toggles the display of gesture indicators.
- P — Pauses and unpauses the visualization display.
- B — Displays screen location visuals. These visuals include a frame showing the computed area of the desktop and the projection of fingers and tools to the point where they intersect the screen. Set the location of a screen using the Leap Motion Settings dialog: see Leap Motion Application Settings.
- D — Mirrors the screen contents in the visualizer window (screen location visuals must also be displayed for the mirrored monitor to be shown).
The Visualizer displays finger tip trails in 3D space. You can control the camera with the following keys:
- = — Zoom the camera in.
- - — Zoom the camera out.
- V — Cycle the camera between the orthographic, front, top, and side views.
- A — Automatically pan the camera to keep tracked fingers in view when they move near the edges.
- C — Recenter the camera to place tracked fingers in the center of the view.
- Left and right arrows — Start and stop view rotation in orthographic view.
- Mouse click and drag — Rotate the camera in orthographic view.
- Mouse right-click and drag — Pan the camera.
