## Appendix E Coding Scheme Revised  
Below are the coding guidelines we recommend; Table A9 contains the phase-specific codes, and Table A10 contains the codes that can be applied in multiple phases. We based these on the Phased Framework [9] and refined them based on our study. Many codes have (+/\(-\)) following their name indicating that that specific code can be used as a positive or negative version of that code to better distinguish quotes during the coding process. In Table A9, codes can appear in several sections and are rewritten to capture these nuanced evolutions appropriate to each section. For example, Use 1.0: Exploration occurs in the Adoption2 phase; users spend time exploring the technology itself. In the Adaptation3 phase, Use 2.0: Incorporation evolves into user exploring how they might use the technologies in the context of their own lives and routines. Non Use phase and codes are not new to literature but new in their relation to this framework [55; 57; 64; 65; 66]. Finally, we chose a broad language to make this coding scheme applicable to any technology during the acceptance process instead of just robots. \begin{tabular}{p{14.2 pt} p{142.3 pt}} \hline
**Experience** & **Description** & **Rationale for Changes** \\ \hline \multicolumn{3}{c}{**Phase 1: Expectation Phase—All codes report to a mindset PRIOR to ENCOUNTERING the technology. **} \\ \hline \multirow{5}{*}{Predictions (+/ -)} & Users predict activities and uses for the technology upon its future arrival. Users consider what they will or might use it for in the (near) future. For example, considering how they intend to use it: Where it will be placed in their home; How it will fit into their daily life; Includes expectations about if they will become emotionally attached, and valence of attitudes they expect to have. \\ \hline \multirow{5}{*}{Association (+/ -)} & Users associate the technology with prior knowledge from their personal experiences and encounters. They associate or connect the technology to something they are already familiar with. Users may cite similarities or differences. This can be relevant to real life experiences (e.g., \"It is like my brother's Roomba\") or knowledge (e.g., \"It is a bit different from Big Dog I saw on the news\") as well as science fiction (movies, television, books). It does not need to be an association related to technology. For example, they may say, \"I don't like new things\"--thus associating it with something new. Associations can also be from other experiences with similar technologies. \\ \hline \multirow{5}{*}{Physical Preparation} & Users physically prepare their homes for the technology's arrival. This might include preparing a safe and secure space for the technology as well as any possible needs it may have (Inter-net/charging ports/etc.). \\ \cline{2-2}  & **Phase 2: Adoption Phase—All codes report to a mindset POST to ENCOUNTERING the technology. ** \\ \hline \multirow{3}{*}{Novelty} & Users are enthralled with the novelty of the technology. Users find themselves amazed, shocked, intrigued, and excited about the new technology. \\ \hline \multirow{5}{*}{Use 1.0: Exploration} & Users spend time exploring the technology and becoming better acquainted with it. This differs from Curiosity as the users actively are exploring possible uses and controls of the technology rather than pondering it. \\ \cline{2-2}  & Users have explored the technology and have run into multiple errors during exploration. \\ \cline{1-1} \cline{2-2}  & **Phase 3: Expectation Phase—All codes report to a mindset PRIOR to ENCOUNTERING the technology. ** \\ \hline \multirow{5}{*}{Predictions (+/ -)} & Users predict activities and uses for the technology upon its future arrival. Users consider what they will or might use it for in the (near) future. For example, considering how they intend to use it: Where it will be placed in their home; How it will fit into their daily life; Includes expectations about if they will become emotionally attached, and valence of attitudes they expect to have.
