## Abstract

A device for generating a projected image based on an activity related parameter includes a first sensor for detecting the activity related parameter, a second sensor for detecting an orientation of the device, a processor coupled to the first sensor for creating information from the detected activity related parameter, a light source for emitting a light beam from the device to project the created information as an image onto a surface outside the device and at least a first actuator for adjusting a relative direction of the light beam with respect to the detected orientation of the device. The surface outside the device is a ground surface and a distance between the device and the projected image is a function of the detected activity related parameter.
