E-Learning Tag der FH JOANNEUM 2019 N2 - Der Einsatz von Lernvideos ist aus zeitgemäßer Lehre kaum noch wegzudenken. Um adäquates, fachlich und didaktisch abgestimmtes Lehr-und Lernmaterial mit angemessenem Ressourcenaufwand zu ermöglichen, ist es für Hochschulen und fachliche ExpertInnen ein sinnvoller Weg, selbst Lehrvideos zu produzieren. Dieser Beitrag stellt ein Beispiel guter Praxis im Aufbau und Betrieb eines E-Learning Labors vor. Dabei werden die Infrastruktur und Technik, das Produktions-Prozedere sowie mediendidaktische und rechtliche Aspekte beleuchtet.

In order to contribute to active safety on the road, we propose in this work a low-cost Forward Collision Warning system that captures and processes images. Using cameras located in the rear section of a leading vehicle, this system serves the purpose of discouraging tailgating behavior from the vehicle driving behind. We perform in this paper the pertinent field tests to assess system performance, focusing on the calculated distance from the processing of images and the error margins in a straight line, as well as in a curve. Based on the evaluation results, the current version of the Tailigator can be used at speeds up to 50 km per hour without any restrictions. The measurements showed similar characteristics both on the straight line and in the curve. At close distances, between 3 and 5 m, the values deviated from the real value. At average distances, around 10 to 15 m, the Tailigator achieved the best results. From distances higher than 20 m, the deviations increased steadily with the distance. We contribute to the state of the art with an innovative low-cost system to identify tailgating behavior and raise awareness, which works independently of the rear vehicle's communication capabilities or equipment.
