How to Improve Tracking & Performance

Improve Tracking & Performance

Here are a few tips that can help improve tracking and performance of the Merge Cube:

  • Use the Merge Cube in a well-lit area
  • Make sure a full side of the Cube is visible
  • Give the Place tool enough visual data

Use the Merge Cube in a well-lit area

Your device's camera needs a clear view of the Merge Cube in order to overlay the science simulation or digital teaching aid and accurately track the cube’s motion. Dark or dim lighting might interfere with your device’s ability to pick up on the cube, so be sure to use Merge EDU in a well-lit area.

For iOS Devices: If you can’t increase the lighting in your room, be sure to turn on the flashlight inside the Merge EDU apps by following the steps below. 

In Merge Explorer:

  1. Open a topic card and press the play button to begin any of the simulations
  2. Tap the 3 dot menu in the upper left corner of the screen
  3. Toggle the flashlight to the on position (it will turn green when on)

In Merge Object Viewer: 

  1. Select any of the digital teaching aids 
  2. Tap the flashlight icon in the upper left corner of the screen 

Make sure a full side of the Merge Cube is visible

When getting started with Merge EDU apps, be sure your device’s camera scans a full side of the Merge Cube. Once the simulation or teaching aid appears, you can rotate and turn the cube to see the object from every angle.

Try not to cover too much of the sides of the cube with your hand. Covering too much of the Merge Cube might cause your device to lose tracking.

Give the Place in World tool enough visual data

The Place in World tool uses your device’s camera to estimate the distance and size of the surface you are scanning. If your device camera doesn't have enough visual information, for instance a blank white wall or floor then the tracking will not be very good. The more visual data - that is, things and textures in the foreground and background of the image - your device has, the more accurate it will be at placing objects in 3D space.

If you are having trouble with placed objects flickering or not staying where they were placed, it may be because your device does not have enough visual information of that area. You can help give your device more to work with by putting a physical object like a rug in the foreground or background of the surrounding area or by moving locations.
