User Manual on Augmented Reality for Installation and Maintenance of the V-Brakes System of a Mountain Bike

Abstract

Until now most traces of AR in applications related to mechanic and maintenance tasks has been performed in very specific systems which could be regarded as quite complex in the field they have been applied to (aircrafts, military equipment, etc.) In this paper we intend making this technology approachable for task and applications more common to everybody. We propose making one of the most frequent maintenance tasks in mountain bikes which is the installation of the brakes system and cartridge shoes as well as adjustment of the tension cable. They are not difficult tasks but making them the first few times may be quite tough for the average user. Therefore, we propose an easy interface based on augmented reality which fitted to the bike handlebars will guide the user step by step through installation of the V-brakes system, change of cartridge shoes and adjustment of tension cable. Interface is based in several cards containing markers with codified sequences based in 3D models for performing maintenance. User will use a mobile phone with camera or a head mounted display (HMD) connected to a PC so he may visualize the animated 3D models of pieces and tools needed for this operation. Virtual objects will be superimposed over the real ones so positions of each piece can be identified by the user before handling them. Final target is including the markers interface with the bike or brakes in their original purchase or making it available for download from a PC via web or as a mobile application.
