This study probes the ethics of intrusive technologies for experimental research in tourism, through the lens of collaborative ethnography. Amidst the increasing uptake of technology to assess participant responses, the role of ethics in an experimental setting has received scant attention in tourism and hospitality. While intrusive technologies such as eye tracking, skin sensors and neuroscience headgear become more ubiquitous, the ethical boundaries of using such equipment are increasingly blurred and inconsistently approved. Seeking convergence of ethics concerning intrusive technologies is complicated when framing political spaces, target audiences and management of data obtained. Rather than view the role of intrusive technologies as a dichotomous outcome of ethical or unethical approaches, this paper argues that ethics needs to be contextually embedded with increased collaboration and co-creation in the application preparation and approval process.
