1		-When it comes to human-robot collaboration and interaction, social factors governing human-human interaction apply equally [1]. This means that often human-human interaction models need to be considered and simulated to make the interactions feel natural and well-received. This means aspects such as gaze, tone, eye contact, and expressions need to be incorporated and these comprise essential parts of human-robot collaboration. Both communication channels and cues are also important [1]. This means that not only are the robot's own communicative abilities important when it comes to human-robot collaboration, but also the robot's ability to interpret and take in cues and communication given or displayed by the human counterpart in any way.

3		-This is central to our project also. Usually, these communications are aided if the robot looks more humanoid, which for elderly care and for PwDs is very likely to be a central aspect, to make sure that interacting with the robot feels natural and does not stray away from regular human-human interaction. We have taken this into account primarily because the older population tends to be less familiar and comfortable with technology on average and to make it a more natural experience that does not necessarily require the PwD to act in any particular way that might not feel comfortable to them.

5		-It is crucial to consider how exactly these ques will the taken in by the robot and what kind of sensors and cameras will be responsible for this. This is also something we need to consider in our design, especially with the Pepper robot who also potentially has the tablet option of communication.
	5	+- Many relevant things about evaluation methods in human-robot interaction studies were described. Not only were different examples of studies highlighted, but also how these were evaluated. The key takeaways here are that: "It is essential to use three or more methods of evaluation to establish study validity. Additionally, it is important to determine the appropriate sample size necessary to obtain statistically significant results." Evaluation methods are also very important for us to consider as we go forward with our design.

7		-===== Regarding conducting studies in Human-Robot Collaboration, we have considered the following: =====
	7	+- In order to conduct a successful HRI study the planning and design stages are also really important. It is essential to determine what type of study will be conducted and what kind of study it will be. For our own study, either within-subjects design or between-subjects design is probably preferred. Which one it will be is not quite settled, since we are still considering the time, learning effect and potential frustrations from similar interactions with the robot. The between-subjects design might be cleaner in this regard, but the results could potentially be affected by the differences among the participants to a larger extent.

9		-Firstly, focusing on the paper //Conducting Studies in Human-Robot Interaction, //many conclusions could be drawn when it comes to relevant evaluation methods in human-robot interaction studies. The relevant takeaways for our study regarded that it is essential to use three or more methods of evaluation to establish a study's validity and that additionally, it is also important to determine the appropriate sample size necessary to obtain significant results. [2] At this stage in our research, evaluation methods are really important to consider and this definitely aids us going forward.
	9	+- Another aspect that this study highlights the study location and environment. It is mentioned that it is important that the study reflects the environment where the application is meant to be used and that conditions should be simulated accordingly. This also ties into the choice of robots for the study. In our case it is important that we try to simulate movement of the robot and the human together and how that could work, which means we need a space that allows for some travel and some movement together with the participant.

11		-Further, in order to conduct a successful HRI study the planning and design stages are really important. Here, we tried to consider what type of evaluation and what kind of study would fit our objective the best and we have considered either within-subjects design or between-subject design. We are still considering the time, the learning effect, and potential frustrations that might come if participants have too many similar interactions with the robot. The between-subjects design might be preferable in this regard, but the results could potentially be affected by the difference among the participants to a larger extent [2].

13		-Another important aspect highlighted in this study is location and environment. It is mentioned that it is crucial that the study reflects the environment where the application is meant to be used and that conditions should be simulated accordingly and that this also ties into the choice of robot for the study [2]. In our case, it is important that we try to simulate the movement and walking of the robot together with the person. This means we need to consider a space that allows for some movement of the robot and participant together. Our goal is to simulate a walk in the garden and it is therefore important that we can mimic these conditions of a walk as closely as we can.

15		-Furthermore, the exemplar study provided [2] was very useful to see a complete structure of a study, performed according to the guidelines. Conducting proper and successful studies is really important for the general field of HRI, since it is rather new, and these studies are always an important step in further normalizing and accepting robots as a part of society and as a helpful component in our lives [2], which is important to remember and hopefully something we can make a small contribution to through completing this course.
