Here's an interesting walking-related project that combines a pedometer (step-sensor) with a camera, to create visual documents of walks, from an unusual point of view (POV). It could provide a way to appreciate and reflect on our surrounds in greater detail and depth. This makes me think you could also explore different narratives and commentaries applied to these images as a slide show, or interactive map, play back afterwards.
Every Step allows a participant to create a short experimental animation while they walk. Each participant is given an armband with a mounted camera and pedometer. The pedometer is mounted inside the armband and is connected to the camera. The camera is mounted on the armband and points towards the sky. The pedometer acts as a trigger for the camera and an image of whatever is above the participant is taken every time a step is made.
