Let’s begin the basic element that required to capture the Gesture.
Gestures are the physical actions that convey some meaningful information. It includes movement of the hands.
The primary goal is to capture the bending information of the fingers through the gesture that conveys some messages.
Hence we need a sensor that can be attached to the fingers and then it can be able to capture the bending details.
The most suitable sensor that can be used to detect bending is Flex Sensor.
A flex sensor or bend sensor is a sensor that measures the amount of deflection or bending. This flex sensor is a like variable resistor. The resistance of the flex sensor increases as the component bends. Since the resistance is directly proportional to the amount of bend.
Here are some photos that depict the flex sensor working
The reading of the multimeter shows the resistance of the Fex Sensor when it is straight and while bending.
