In this paper we analyze pointing techniques for simple remote control of nearby and distant objects in an outdoor environment, using a mobile phone. In an experiment we determine the accuracy of pointing at targets from a few meters to a few hundred meters away, either by focusing the phone's camera on a target or holding the phone at waist level in the direction of the target. We describe a simulated network application in which users can activate and control one or more responsive objects using either interaction technique.
