The four AR device categories have been selected as a potential tool to be applied by the firm for developing their own AR-based solution: haptic and force feedback devices could be used to sup- port operators about how to perform a specific task in restricted spaces (see Fig. 3 ), HMD and projectors could provide flexible sys- tem for providing operations sequences of maintenance tasks as well as data about equipment ( Bueno Espindola et al., 2013 ). The aim of the analysis is to evaluate how different technological fea- tures characterizing each AR device could be “measured”in terms of process based requirements.
