Method and body garment for pose-driven determination of a location of a body include: selecting a predetermined location of the body; determining a mode of locomotion of the body as the body moves; inferring the movement of the body and direction of the movement over a time period by combining physiological information of the body with calibration data; calculating a path travelled by the body from the predetermined location; capturing spatial environment of the body and its features, and a current location of the body within the spatial environment, by performing simultaneous localization and mapping (SLAM) on the path travelled by the body; and calculating navigation information of the body without using a location determining device.
