Do you ever want to touch the Virtual Objects

Scientists from EPFL and ETH Zurich have developed an ultra-light glove

It will be shown at the upcoming ACM Symposium on User Interface Software and Technology (UIST).

Key Features of Ultralight gloves

  • Ultralight gloves are made up of nylon with thin elastic metal strips.
  • It weighs less than 8 grams per finger that enables a person to sense and control virtual objects.
  • Runs on a very small battery.
  • Its system provides extremely realistic haptic feedback.
  • Allows nonparallel freedom from movement.
  • It is able to create up to 40 Newtons of holding force on each finger with just 200 Volts and only a few MilliWatts of power.
  • Has a thickness of only 2mm.

Working procedure of this Glove

Ultra light Gloves  made up of nylon with thin elastic metal strips running over the fingers. There is an insulator between the strips. , the controller applies a voltage difference between the metal strips when the user’s fingers come into contact with a virtual object which causes them to stick together by means of an electrostatic attraction – this generates a braking force that restricts the finger’s or thumb’s movement. The low power does not create the movement but blocks one.  Once the voltage is removed, the metal strips glide smoothly and the user can once again move his fingers freely.

Applications

  • These gloves have a huge scope in healthcare applications for training surgeons.
  • Gaming will be the biggest market.
  • Transparency in scientific models.

Herbert Shea, head of EPFL’s Soft Transducers Laboratory (LMTS) said that we wanted to develop a lightweight device with no bulky cables  and exoskeleton

Shea  explains Human sensory system is highly enlarged and highly composite. A human body has a very different kind of receptors at a very high density in the joints of our fingers and embedded in the skin. Our upcoming step will be scaled up the device on other parts of the body.

As a result, providing realistic feedback when interacting with virtual objects is a very demanding problem and is currently unsolved.
