Indoor Path Tracking using Inertial Measurement Unit(IMU)sensors

Overview: This is a device that would show the real time position of a person wearing the device. This device should have high accuracy as it deals with indoor path tracking, the error rate should only be up to 0.5mts or 1mts at max. This is a device which would be worn on the hand of the person whose position has to traced, for eg: if a person is wearing this device and moves from point A to point B the path along which the person travels has to be traced on the device. The components of this device would be a display of about 4.7 inch with the electronic part connected to it. The device should work on a battery which would run the device for a minimum of 4 hours. The skill set required for the making of this device are: knowledge on IMU sensors(sensors such as accelerometer, gyroscope, magnetometer), python/c/c++, basic electronics, Raspberry pi, node js and GUI. This device should depict a 3D or a 2D representation of the movement of the person on the device, the map or the grid should be a plane graphical representation of the person in a space this means that the visual to the person wearing it should be his location in an open area in real time. And as he starts moving his path should be traced, the view on the device should be a top view representation.
