Abstract
A device for providing spatial information to a user. The device includes a camera configured to detect image data. The device also includes an accelerometer configured to determine step data. The device also includes a processor connected to the camera and the accelerometer and configured to determine a distance travelled per step of the user based on the image data and the step data. The processor is also configured to determine a distance to a reference point based on the image data. The processor is also configured to determine a number of steps corresponding to the distance to the reference point based on the distance travelled per step of the user. The device also includes an output unit connected to the processor and configured to output the spatial information indicating the number of steps corresponding to the distance to the reference point.
