The inner glove is designed to be detachable from the motorized feedback mechanism so it can be washed/replaced. It does have some attachment components, so the gloves should be hand-washed and not put in a washing machine.
The SDK reads the data from the five sensors and does all kinematic calculations for you. From there our software generates the rotations for all the knuckles in the hand. This can easily be hooked up to hand models that are rigged for animation. The SDK will ship with an example pair of hands to make devlopment as easy as possible,
The SDK is designed for easy integration. We also have pre built scripts to make objects squishy, breakable, or rigid, or you can write your own scripts for any unique material properties and profiles.
VRgluv will simulate the surface of the wall/table and restrict forward motion, but only in the fingers. Currently the glove can not restrict arm motion, although we would love to develop the technology further in the future!
We use neither IMUs or flex sensors for finger tracking. We have found that IMUs tend to drift and require constant re-calibration and flex sensors have a limited lifetime. Our proprietary finger tracking and force feedback technologies are closely integrated, and the word will be out when we ship our first units later this year.
