## 3 Experimental Environment and Results
### Findings from the Interviews  
The results from the interviews are organized into five main themes: adaptability, usage areas, development, interaction and behavior, and credibility. Each theme includes sub-themes that provide additional insight into participants' perceptions and experiences with the robots. Adaptability. This theme addresses the importance of a robot's flexibility to adapt to various situations, aligning with [PERSON]'s [7] concept of situativity--how a robot's behavior adapts to its environment, influencing user engagement and perceived realism. Participants expressed that robots should adapt to different user needs and preferences, with one envisioning that robots could perform different tasks with simple configuration adjustments, as exemplified by the statement, \"A robot should be able to do several different things; you could change it just by pressing buttons so that it can do this task instead\". These findings highlight the perceived importance of adaptability for enhancing the acceptance and accessibility of robot technology across multiple environments. Usage Areas. Participants suggested that adaptable robots could serve a variety of purposes, from performing simple chores like cleaning to providing guidance at airports or customer service in healthcare. Examples included support in nursing homes, assistance with documentation in construction, and aiding new employees in companies. A common theme among participants was that robots could best handle tasks that do not require human interaction. One participant stated, \"There are tasks where there is no need for human contact but where things need to be fetched or information conveyed\", reflecting a general perception of robots as ideal for routine, low-interaction tasks. Development. The development theme emphasizes participants' desire for robots to exhibit a more \"human touch\" in their interactions, a feature they felt would improve user experience. One participant suggested that for robots to be widely accepted, they should offer a more human-like experience, remarking, \"[...] they need to be developed a bit more so that it feels like a human encounter, as it seems that many highly value this\". Another participant highlighted technical improvements, suggesting that communication enhancements would aid interaction, particularly for users with hearing difficulties. This theme underscores the need for ongoing development in both technical performance and human-like qualities. Interaction and Behavior. This theme explores participants' ease or challenges in interacting with the robots, referencing [PERSON]'s [7] ideas on interactivity and proxemics, which describe the influence of interaction quality and physical proximity on user comfort. Participants generally found the robots, especially [PERSON], helpful, noting that [PERSON] displayed positive, welcoming behavior and responded well to feedback. One participant observed, \"Yes, the other robot [[PERSON]] was better at that. It seemed like it perked up when told it had done a good job\". However, some participants experienced confusion around where to position themselves relative to the robots, especially when [PERSON] was slow to respond, creating uncertainty. This feedback highlights how the robots' response times and movement speed could impact user experience. Gestures and Body Language. Participants noted that [PERSON]'s gestures and body language varied in perceived human likeness, with some finding its movements \"cute\" and others \"uncomfortable\". While some participants felt [PERSON]'s expressive gestures made it more human-like, others found these gestures disconcerting. For instance, one participant remarked, \"The white one [[PERSON]] was uncomfortable...too much hand, neck, and waist movement to be reasonable for a robot\". This divergence in perception underscores the impact of gestures and body language on users' comfort levels. Interaction. Participants had mixed responses to the robots' perceived emotional capabilities.
