Self-Reflection: In this course, we designed a prototype of a robot that helps patients with dementia to recall their memory and enhance their well-being. I enjoys the process of discussing with my team members to make our goal clear, brainstorm an ideas and finalize a prototype that we all aggred on. I am mainly responsible for creating coherent personas and stories used for evaluation of the robot. Besides, I also help other groups' evaluation with their prototype, and participate in hosting our own evaluation, and in the end presents our results. In this course, I learned a lot about the human-robot interaction, and how to design a robot prototype that can help to increase human's happiness; Besides, I also become familiar with the procedure of evaluation that needs people to involve, including get their consents and keep their privacy.
