Our domain research study is improving the collaboration between all generations of people using the game recommendation feature provided by Nintendo Switch technology. We knew that some of the old generations may have trouble choosing a game since they are not familiar with Nintendo Switch technology and games. Our target user is the old generation of people. By conducting various usability tests about using a game recommendation feature, our group focuses on which parts of the feature to be changed or improved to be easily used by users, especially old generations of people. We observed how users use our game recommendation feature by providing an interactive prototype of the feature, and this leads to the research insights on which parts of the feature the user is having a hard time using since they are not familiar with the technology or the design of the product interface.
