A number of organizations in cultural tourism have started to explore the use of augmented reality (AR) to enhance visitor experience. While many studies have been conducted to identify adoption criteria of mobile AR applications, research exploring the adoption of augmented reality smart glasses (ARSG) is still limited. This paper contributes to the technology adoption literature by investigating attributes of visitor adoption of ARSG in cultural tourism. Twenty-eight interviews were conducted with visitors to a UK art gallery, where they experienced an ARSG application. Findings inform an ARSG adoption framework that integrates societal impact, perceived benefits, perceived attributes of innovation, and visitor resistance as the main themes of ARSG adoption in cultural tourism.
