Calibration

The video above shows the earlier four-step calibration. From MANUS Core 3.2.0 the flow continues with four pinch steps, described below.

It takes 8 short steps to calibrate Metagloves Pro to your hands.

During the calibration, MANUS Core determines the dimensions of your hand skeleton and how to map the glove sensor data onto your digital fingers. The first four steps capture your hand pose and finger motion. The four pinch steps that follow tell MANUS Core how your thumb meets each finger, which is what makes pinching in your digital hand line up with pinching in the real one.

Calibration Steps

Step 1

Place your hand on a horizontal non-metal surface.

Step 2

Make a fist.

Step 3

Open and close your fingers continually.

Step 4

Touch your knuckles with your thumb.

Pinch steps

The last four steps are pinch poses, one for each finger. Holding a pinch shows MANUS Core exactly where your thumb tip is when it touches a fingertip. Each pinch is held for about three seconds.

Pinch lightly, tip to tip

Touch the very tips of your thumb and finger together, as if you were picking up a grain of rice, and hold still. Do not press hard. Pressing squeezes the fingertips into each other well past where they would really touch.

Step 5

Pinch your thumb and index finger.

Step 6

Pinch your thumb and middle finger.

Step 7

Pinch your thumb and ring finger.

Step 8

Pinch your thumb and little finger.

After finishing the calibration steps for your left hand, follow the same steps for your right hand.

Calibrating both hands is worth doing even if you only intend to use one glove: once the second hand is finished, MANUS Core compares the two hands and refines both thumbs together, which is more accurate than either hand on its own.

Visual inspection

With both calibrations finished, you can visually inspect the calibration result in MANUS Core.

For the best result, we recommend calibrating your gloves for every use.

Manual Measurements

In addition to the automated calibration process, Metaglove Pro users have the option to manually refine their calibration using manually acquired hand measurements.
This allows for precise adjustments in cases where the automated calibration does not fully capture the user’s anatomy, or when higher accuracy is required for specific applications.

With manual measurements you can:

  • Adjust individual finger segment lengths and thicknesses.
  • Correct for variations in glove fitment specific to the user.
  • Save and reuse calibration profiles for consistency across sessions.

A full set of measurements is rarely needed: when the calibration performs well overall but fingertips do not quite meet when pinching, adjusting only the Tip to casing values is usually enough.
