Abstract
An elongated member is provided with one or more imaging sensors, location sensors, and a switch in its bottom end. For example, in an embodiment the elongated member may be a walking stick and the one or more imaging sensors may be one or more cameras Such a walking stick takes pictures of its surrounding environment and keeps records of its location when the switch touches the ground, so that the pictures and location information can be used to create a virtual simulation of the area that a user of the walking stick has walked through.
