Abstract
Technologies for directional wayfinding include a mobile computing device having one or more local location sensors to generate data indicative of movement of the mobile computing device. The mobile computing device captures first sensor data indicative of movement of the mobile computing device along a path and determines a series of waypoints based on the first sensor data. The waypoints may describe movement data of the mobile computing device, including length and direction of movement. The mobile computing device determines a series of directional instructions to guide a user of the mobile computing device back along the path in the reverse order and presents the directional instructions to the user. The mobile computing device may monitor the sensor data to determine whether the user has arrived at each waypoint while reversing the path. The sensors may include an accelerometer, gyroscope, magnetometer, or altimeter. Other embodiments are described and claimed.
