This exploratory study provides a platform for extending the body of knowledge associated with the nature of perceived invasiveness toward biometric technologies. This analysis of perceived invasiveness was conducted via consideration of situational factors which may influence an individual's willingness to use such technologies. Specifically, this research validated a proposed conceptual model and tested hypotheses which evaluated if the eye was viewed as a significantly more sensitive or invasive area of the person than the hand when subject to appraisal by biometric devices. The primary outcome of the study indicated that, within the air travel security instance, the factors of use context, preference, and proxemic sensitivity are correlated with an individual's perceived invasiveness toward eye-based biometric technologies. The results also indicated that only the factor of proxemic sensitivity was correlated with individual's perceived invasiveness toward hand-based biometric technologies. Consequently, only the factor of proxemic sensitivity was indicated to be correlated with individual sentiment of perceived invasiveness toward biometric technologies, regardless of the class of biometric technology under consideration.
