Query: Segmented and Directional Impact Detection for Parked Vehicles using
  Mobile Devices   Mutual usage of vehicles as well as car sharing became more and more
attractive during the last years. Especially in urban environments with limited
parking possibilities and a higher risk for traffic jams, car rentals and
sharing services may save time and money. But when renting a vehicle it could
already be damaged (e.g., scratches or bumps inflicted by a previous user)
without the damage being perceived by the service provider. In order to address
such problems, we present an automated, motion-based system for impact
detection, that facilitates a common smartphone as a sensor platform. The
system is capable of detecting the impact segment and the point of time of an
impact event on a vehicle's surface, as well as its direction of origin. With
this additional specific knowledge, it may be possible to reconstruct the
circumstances of an impact event, e.g., to prove possible innocence of a
service's customer.
