Health care professionals regularly require access to information systems throughout their daily work. However, existing smart devices like smartphones and tablets are difficult to use at the point of care, because health care professionals require both hands during their work. Following a design science research approach including ethnographic fieldwork and prototype tests with focus groups, we find that Augmented Reality smart glass applications offer potential for service innovation in the health care sector. Our smart glass prototype supports health care professionals during wound treatment by allowing them to document procedures hands-free while they perform them. Furthermore, we investigate the use of audio based and physical interaction with the smart glasses in a within-subjects design experiment.

Digitization in the health care sector is striving forward. Wearable technologies like smart glasses are being evaluated for providing hands-free and septicsafe access to information systems at the point of care. While smart glasses hold the potential to make service processes more efficient and effective, it is unclear whether patients would opt-in to treatments involving smart glasses. Patients are not active users of smart glasses but are nevertheless affected of outcomes produced by the symbiosis of health care workers and smart glasses. Using an online survey with 437 respondents, we find that it is important to properly explain to patients why smart glasses are being used and to proactively address data privacy concerns. Otherwise, smart glasses can significantly increase risk perceptions, reduce patients' estimates of health care workers' abilities, and decrease patients' willingness to opt-in to medical procedures.
