Head-mounted displays and ot her wearable devices open up for innovative types of interaction for wearable augmented reality (AR).\nHowever, to design and evaluate these new types of AR user interfaces, it is essential to quickly simulate undeveloped components\nof the system and collect feedback from potential users early in the design process. One way of doing this is the wizard of Oz (WOZ)\nmethod. The basic idea behind WOZ is to create the illusion of a working system by having a human operator, performing some\nor all of the system�s functions.WozARd is a WOZ method developed for wearable AR interaction. The presented pilot study was\nan initial investigation of the capability of the WozARd method to simulate an AR city tour. Qualitative and quantitative data were\ncollected from 21 participants performing a simulated AR city tour. The data analysis focused on seven categories that can have\nan impact on how the WozARd method is perceived by participants: precision, relevance, responsiveness, technical stability, visual\nfidelity, general user-experience, and human-operator performance. Overall, the results indicate that the participants perceived\nthe simulated AR city tour as a relatively realistic experience despite a certain degree of technical instability and human-operator\nmistakes.
