Synertial’s IGS Cobra gloves feature their brand new IMU technology, completely new software & SDK based on 20+ years of mocap know-how. The result is the most accurate and comfortable occlusion free finger-capture equipment to date.
Synertial’s new Hybrid position sensors easily augment any of our new Cobra Gloves for accurate wrist position tracking in real-world space. Large optical mocap suits consider the Optinertial Cobra Gloves to be the best possible solution for simultaneous occlusion-free mocap that happens during massive multi-person capture. The data Synertial produces is perfectly synchronized and ready to use immediately after the take. Yes, you’ve got that right. The raw data is well-done.

In short
7-Sensor Gloves: (Yellow from the above image) Our 7-sensor gloves use interpolation to approximate the untracked finger joints on all but 6 phalanges, which use IMU (Inertial Measurement Unit) sensors; the 7th sensor is for the palm. The 7-sensor gloves are the state of the art in axis-scaling technology, which is proprietary to Synertial. The reason no one has succeeded in providing a usable 7-sensor glove, is that no one has been able to scale individual axis of a sensor before (they can only scale the whole sensors or nothing). Our gloves not only interpolate each axis independently, but they also allow the user to modify its rate for a perfect fit (not hard-coded).
13-Sensor Gloves: (Yellow and Green from the above image) Our 13-sensor gloves only leave the finger tips (distal phalanges) for interpolation. The 13-Sensor glove is an all-arounder, satisfying most applications, except for when the application of force to the fingertips disrupts natural interpolation values, as tendons are forced backward.
16-Sensor Gloves: (Yellow, Green and Orange from the above image) All pure data except for the pinky fingertip.
Optional Lower Arm and Upper Arm Sensors: (In Blue in the above Image) As many glove applications require arm data.
What is Unique?
- Instant calibration using savable files (no Wrestling involved)
- Change cloth sizes in minutes (detachable electronics)
- Same electronics used for the left and right gloves
- New pinky and ring metacarpal sensors (Palm Flex)
- First ever Hollywood production-grade sync system
- Patent-pending finger-sized measurement system
- Patent-pending Calibration Mittens
- Umbrella editing of all takes with skeleton-modification
- Minimize down-time through user-friendly sensor HW replacement methods
- User controlled scaling of sensor-data per each axis
- Calibration poses can be custom-made using Synertial's SynDash
- Naked fingertips even for 16-sensor systems
Revolutionary Palm Flex Sensors
The 13 and 16-sensor motion capture gloves now include an additional palm-flex sensor for greater positional accuracy of base and tips of fingers. No other motion capture gloves provide such a thorough measurement of palm-flex.
Better palm-flex measurements are one of many ways Synertial's IGS gloves outperform any existing mocap gloves.
Perfect Sync with Optical Rigs
Synertial's best-in-class finger capture solutions were designed specifically for Vicon's Blade and Optitrack's Motive software in mind:
- Occlusion-free finger capture: Fingers are almost always occluded during multi-person optical takes; Our Optinertial mocap gloves provide pre-solved hand and finger data that is perfectly synchronized with the optical data.
- Glove Combinations: Intermix pairs of 7, 13, and 16-sensor gloves as needed
- KINEXACT HAND: Use Kinexact-Hand software for exact performer hand-skeleton measurements
- Instant Calibration: Synertial's Calibration Mittens place hands into the optimum posture during instant calibration
- Peace of Mind: Can be worn underneath optical markers
- 4 Pairs on 1 PC: Manage up to four pairs of gloves per PC
- Device Driver: All glove pairs on the same device driver inside MoBu
- Sync Software: Separate sync HW powered by processing hub (no additional sync power needed)
- Jam-Sync: Low-drift sync HW (jam-sync once or twice per session)
- From Inside Blade or Motive: Start and stop glove takes triggered from inside Blade or Motive
- Frame Time-Stamps: Precise frame time-stamps down to 1/100 of a sec and up 1000 FPS (29.97 standard)
- Takes Named Automatically: Glove-takes automatically share the same name with the corresponding optical names)
- Hot-Swappable Batteries: Change batteries without needing to restart or recalibrate
Synertial's Calibration Pipeline (Patent Pending)
- Key components for exacting IMU system calibration:
- Measurement: Correct measurement of finger bone length, almost impossible to determine manually, and
- Structure: Exact matching of the geometric structure of an actor's skeleton to the geometric structure pre-configured in the matching calibration file, at the instance of initialization
Phalanx Length Measurement
Synertial has a tool to provide automated length measurement of phalanges: KINEXACT-HAND. Kinexact uses a hand scan to output a MoBu or a Synertial-based format skeleton file with correct joint positions and angles.
User and Calibration File Matching at Initialization
The second key component to precise calibration is to hold the user's segments in the same pose as the pre-configured calibration file for the initialization process.
In theory, once the two are identical (in addition to accurate phalanx lengths), the streaming process can begin accurately.
This matching of the two poses consistently is practically impossible without a mechanism to hold the user's finger-skeleton in such a pose. Hence Synertial has developed calibration jigs, Synertial's Patent-Pending Calibration Mitten, which forces the user's hands to match a pre-configured template.
In addition to the Synertial's Calibration Mitten locking in the required hand-pose locally, the actor uses the spirit levels on the Mitten to orient the hands globally in reference to gravity, to provide sub-degree accuracy in initialization.
These tools help professionals count on repeatable and precise calibrations, taking the guess-work out of successful initialization processes.
