35	35	Then we were introduced to scenario-based design and its benefits in reflecting the current situation (problem scenario) and the envisioned future (design scenario). We used our personas and value stories to formulate the problem and design scenario which would then be formalized into our main Use Case.

58		-My teammates presented the Foundation and Specification of our project. Our presentation was focused on detailing the environment, stakeholders, and persons for our system. We further dived into our problem and design scenarios, and our design plan for a robotic intervention for people with dementia through interactive storytelling, backed by scientific sources. The question/answer session helped provide a third-person view of how our design was perceived by others and how we could improve it. We got valuable feedback for the presentation, specially around designing our evaluation study for what was feasible for our scope.

77		-We worked on building the IDP by exploring how the different actors in our scenario could and should interact with each other. This shaped the TDP for our main use case of the interactive storytelling session. Through this process, I learnt the importance of pattern-based design in identifying recurrent/generalizable problems within a context and defining structured descriptions for the solution to it.

82		-We also learnt about how evaluations should be planned for our prototype. The purpose of the evaluations is to assess the claims at the task level and check the usability of the interaction design. We were introduced to various approaches, like qualitative analysis to formulate hypothesis and quantitative analysis to test the hypothesis.
83	83
84		-We explored the formative and summative evaluations that could be conducted for our system. We decided to focus on the summative evaluation to assess the overall effects of the system. Also, a formative evaluation would not have been feasible within the limited time.

86		-For our measurements and metrics, we used the Godspeed questionnaire for a standardized assessment of our robotic agent. It address factors like being interactive, inert, animate, etc which were relevant for our use case. For the effects, we prioritized measuring the following: the mood of the patient post activity (subjective) and whether the patient finished their meal and in how much time (objective). However, we identified that due to the practical issue of not being able to test with actual dementia patients, the objective measures would not be collected accurately.

95		-The focus of this week was implementing our prototype and testing it out within our group. We used Interactive Robots to program the Pepper robot with two pre-filled story templates - Picnic and Thanksgiving - for the testing of our Interactive Storytelling session use case. During this process, we built two versions of each story, non-interactive: one with simple narration and another, interactive: with inbuilt prompts to spark conversations. We planned to gauge the usefulness of the interaction design in our evaluations through comparison of the experimental interactive scenario with the control non-interactive scenario.

98		-With implementation, we faced some challenges with the Pepper robot in using its tablet and getting it to recognize our speech and touch input. We were able to mitigate them by coming up with alternatives such as touch action on remote laptop screen through clicks, in order to preserve the flow of interactions. Working with the Pepper robot and being able to self-test the functionality we envisioned to build was quite interesting and further helped refine the design we had been building through our incrementally iterative design process.

103		-The focus of this week was conducting the evaluation for our prototype with participants and analyzing the results. We had prepared the participation consent form and the measurements questionnaire along with the prototype on the Pepper robot. Since we had limited time and a limited number of participants, we decided to conduct a within-study evaluation, wherein we would have each participant evaluate both the control and the experiment scenario. We also decided that for half of the total evaluation sessions, we would present the participant with the control scenario first, and for the other half, we would present the experimental scenario first. This strategy was employed in order to mitigate carry-over bias.
104		-
105		-For each evaluation session, the participants first signed the consent form. Then they engaged in the first storytelling session, filled in the questionnaire, engaged in the second storytelling session, and filled in the questionnaire again. It was really interesting and informative to see how the participants responded to our interaction design, and how our system was perceived by them. Further, participating in other groups’ evaluation sessions also provided a broader view of the kind of effects our peers were trying to have with their design and what they considered worthwhile to measure.
106		-
107		-With the evaluation completed, we analyzed the results through a statistical test to determine significant results. With this, our claims around improving the mood of the person with dementia through interactive storytelling were confirmed. The entire process taught me a lot about how to assess a system design in terms of the claims it makes for the effects it wants to achieve.

112		-We compiled our project work and the results from the evaluation and I along with two of my teammates presented them to the class. We received interesting questions from our peers and the professors, which further helped us critically reflect on our design decisions. I also had an interesting discussion about designing the system in a way such that it minimises the possible negative effects that it could also have.
