It should be worn close to the Chest Skin, and it starts analyzing our posture with its point of view according to the Degree of Walking, Heartbeat and many more similar factors like that. The Gadget can be worn as a Locket in a chain or can be placed using stick pads, or even attached to the Bra Straps.
