SYNERTIAL

7, 13 or 16 sensors

Each glove includes a choice of 7 sensors, 13 sensors or 16 sensors.

 

 

7, 13 or 16 Sensors

  • Stand-alone, bundled with a suit, or multiple pairs for use with optical rigs
  • Self-calibrating sensors to adapt to magnetic environments
  • User-configured kinematic structures
  • Instant calibration (configurable calibration poses)
  • Replace batteries and continue capturing where you left off without SW restart or recalibration in MoBu, Unity, etc.
  • Occlusion free
  • Extremely accurate clock in the sync system for Optical rig integration (Vicon, Motion Analysis, Optitrack)
  • RealTime in Motionbuilder, Unity, Unreal, and Siemens Jack
  • Free user-friendly SDK and samples included with MoCap SW
  • Detachable electronics; change sizes in minutes
  • Short and long-fingered glove cloth types available

 

 

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.

Revolutionary Palm Flex Sensors

The new Cobra 4th generation gloves have incorporated a second sensor on the palm to manage pinky and ring metacarpals.  

Putting sensors on metacarpals have always proved impossible due to the fact that metacarpals were joined with other anatomy, not independent like finger phalanges, and accordingly impossible to MoCap without unwanted data artifact.

New Synertial technology allows collection of data not only on particular axis of local coordinates (configurable by the user), but it also can scale to portions of such data.

The new sensor provides part of the pinky metacarpal and half as much of the ring metacarpal; these amounts are user-controlled.

The results are clearly visible when the palm is caved-in or when fanned-out...

Perfect Sync with Optical Rigs

Synertial's best-in-class finger capture solutions were designed specifically for Vicon's Blade and Optitrack's Motive in mind:

  • Palm Flex:  Recently added second palm sensor provides never before data collection of palm flex

  • Glove Combinations:  Combined 7, 13, and 16-sensor gloves into any appropriate combinations

  • KINEXACT HAND: Use Kinexact-Hand software for exact individual phalanx measurements

  • Instant Calibration:  Synertial's Calibration Mittens force hands into optimum posture during instant calibration 

  • Peace of Mind:  Wear under passive markers for extra security and peace of mind 

  • 4 Pairs on 1 PC:  Manage up to four pairs of gloves on one 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 named automatically (as their corresponding optical take names)

  • Change Batteries:  Change batteries without restart or recalibration in MoBu

Synertial's Patent-Pending Calibration Pipeline

  • Key components for a precise IMU system calibration are:
    • Measurement: Correct length measurement of segments corresponding with each sensor (which is 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 the only solution in the market that provides automated length measurement of phalanges using its patent-pending solution: the KINEAXCT-HAND.  Use any ordinary scanner, save in png format, feed it to the software, and receive an output in MoBu or a Synertial-based format skeleton file with exact phalanges and measurements in minutes.

 

 

 

 

 

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.

 

 

 

 

 

 

 

 

 

What The Competition Does Not Understand

  • Initialization is the Key to Accuracy; other systems will not be able to duplicate initialization in a repeatable and accurate way.
  • Everybody's finger sizes and skeleton structure is different; the competition's kinematics are hard-coded and do not account for the differences in size and structure.
  • Sensors cannot be displaced from the skin after initialization.
  • Sensors need to be as far away from the knuckles as possible.
  • Gloves cannot be loose, but tight gloves cut off circulation.
  • Accurate finger capture without naked fingers is highly impractical.
  • Without palm flex sensors, across-the-board finger capture accuracy is next to impossible.
  • Calbiration poses need to be custom-made.
