## 4 Identifying Challenges in RSA: User Interview Study
### Challenging Indoor Navigation Experiences  
All our interviewees commonly mentioned that indoor navigation was more challenging for them, as well as for the agents. Interviewees' indoor experiences with RSA indicate that it usually took much longer for the agent to locate and find targets in indoor spaces.  
\begin{table}
\begin{tabular}{p{142.3 pt} p{142.3 pt}} \hline \hline
**Outdoor Scenarios** & **Indoor Scenarios** \\ \hline
1. Going to mailbox & 1. Finding trash cans or vending machines \\
2. Taking a walk around a familiar area (e.g., park, campus) & 2. Finding architectural features (e.g., stairs, elevators, doors, exits, or washrooms) \\
3. Walking to the closest coffee shop & 3. Finding a point of interest in indoor navigation (e.g., a room number, an office) \\
4. Finding the bus stop & 4 *. Navigating malls, hotels, conference venues, or similarly large establishments \\
5 *. Crossing noisy intersections without veering & 5. Finding the correct train platform \\
6. Calling a ride share and going to the pick-up location & 6. Navigating an airport (e.g., security to gate, gate to gate, or gate to baggage claim) \\
7 *. Navigating from a parking lot or drop-off point to the interior of a business & 7. Finding an empty seat in theaters or an empty table in restaurants \\
8 *. Navigating through parking lots or construction sites & \\ \hline \hline \end{tabular}

Table 2: All 15 scenarios were reported by all RSA users. Scenarios with * occurred more frequently than others. Additionally, participants perceived these as more challenging than others.  
[PERSON] shared her challenging experience of spending about 20 min with an RSA agent only to find a store (\"Bath and Body Works\") from another store in a big mall. Another interviewee, [PERSON], recounted the longest and the most challenging time she had with an agent when trying to find the luggage section in a department store, Kohl's.  
Finding the entrance (or exit) of a building and navigating to a pick-up point from the interior of a building to meet the ride-sharing driver are examples of other challenging experiences that our interviewees shared with the RSA agents.  
Users' Understanding of Problems: Insufficient Maps, RSA's Unfamiliarity of Area, and Limited Camera View  
All interviewees mentioned that the absence of maps or floor plans and the inaccuracy and scarcity of the map were the primary reasons why RSA agents struggled to assist them in both indoor and outdoor places. Most interviewees also mentioned that the RSA agent's unfamiliarity with a place and its location is a significant challenge.  
Several interviewees' accounts also suggested that poor and limited visibility caused by the narrow camera view creates challenges for the agents. [PERSON] talked about using stairs in her school and showed her understanding of the agent's visual challenge caused by the limited distance that the camera feed can show. She also introduced another visual challenge that the current camera's capability cannot solve, and [PERSON]'s comment implies the same issue.
