This document summarizes a presentation on the determinants of untact service use. It conducted 13 semi-structured interviews to explore this topic. The key determinants identified were convenience, limits of personal contact, type of product/service, familiarity with technology, and openness to technology. The study provides a first theoretical perspective on the determinants of untact services and their impact on experience co-creation. However, it has limitations like a small sample size and focus on one technology. Further quantitative research is needed to confirm these findings.
