Both of these patents are related to haptic feedback VR gloves. According to the description, haptic feedback gloves implant so-called 'Tendons' (similar to the muscles of human muscles) into the weighting device to simulate touch in the VR world. Tendons are on the user's back At the top of the line, when you touch an object, it generates resistance, which means that when you complete a variety of tasks, such as pressing a button and picking up something, it feels more real.
However, from the point of view of documentation, it seems that there are only two Tendons on the glove, which means that each finger may not support touch feedback. This design may be considered because we use the thumb and index finger more often.
