Nowadays, many modern mobile computing devices such as smartphones are equipped with GPS hardware but using it is rather energy demanding. The systems' uptime strongly depends on the frequency of performed positioning requests. Especially if applications require a continuous location determination (navigation system, tourist guides, etc.), energy becomes an important and limiting factor. Most of these applications do not need exact position data, but less precise (semantic) location information. In this paper, we discuss the idea of postponing position measures until the location could have changed. We focus on walking pedestrians. We present the theoretical framework and implementation aspects. The evaluation results show that our approach requires less energy than GPS polling, but offers a suitable precision.
