16 families of Haptic Feedback:

TeslaSuit: The Teslasuit is built around neuromuscular stimulation, where the conductive smart fabric delivers tiny mild electric pulses to various part of the body.

Simulation: vary from wind or rain sensations to shots and touches

NullSpace:  It allows a user to interact physically with the virtual world around them. The Hardlight suit provides 16 families of vibro-tactile feedback using technology similar to the vibrate function of most cell phones.

AxonVR – HaptX: a thin, flexible haptic textile made up of an array of microfluidic actuators. By varying pressure and temperature at each actuator, HaptX creates sensations ranging from the brush of a butterfly’s wings to the impact of a punch. From the warmth of a cup of coffee to the chill of a snowball. HaptX can bring the sense of touch to any surface.

I’m not very sure about this microfluidic actuator. Looks like it is stimulus-active polymers and composite materials change shape or exert mechanical force on surrounding fluids in response to electric, magnetic, light, thermal, or water/solvent stimuli.

GloveOne:

  • 10 vibrotactile actuators
  • Hand orientation with 1 IMU

Manus VR glove:

  • Vibration motor for haptic feedback
  • Each finger contains two sensors that track its movement.
  • each glove contains a gyroscope, accelerometer and magnetometer to measure the orientation.

Gest:

Motion tracking with multiple IMUS

 

In a nutshell,

tech for tracking fingers: IMUs, Flex sensor

tech for haptic feedbacks: Vibrations, neuromuscular simulation, physical shape change.
