Concept Test of a Smoking Cessation Smart Case.

Abstract

Background: Wearable/portable devices that unobtrusively detect smoking and contextual data offer the potential to provide Just-In-Time Adaptive Intervention (JITAI) support for mobile cessation programs. Little has been reported on the development of these technologies. Introduction: To address this gap, we offer a case report of users' experiences with a prototype "smart" cigarette case that automatically tracks time and location of smoking. Small-scale user-experience studies are typical of iterative product design and are especially helpful when proposing novel ideas. The purpose of the study was to assess concept acceptability and potential for further development. Materials and Methods: We tested the prototype case with a small sample of potential users (n = 7). Participants used the hardware/software for 2 weeks and reconvened for a 90-min focus group to discuss experiences and provide feedback. Results: Participants liked the smart case in principle but found the prototype too bulky for easy portability. The potential for the case to convey positive messages about self also emerged as a finding. Participants indicated willingness to pay for improved technology (USD $15-$60 on a one-time basis). Discussion: The smart case is a viable concept, but design detail is critical to user acceptance. Future research should examine designs that maximize convenience and that explore the device's ability to cue intentions and other cognitions that would support cessation. Conclusions: This study is the first to our knowledge to report formative research on the smart case concept. This initial exploration provides insights that may be helpful to other developers of JITAI-support technology.
