An evaluation model for interactive gaming furniture design based on parent-child behavior

This study takes the parent-child game behavior of children aged 3~6 and their parents as the research object, and extracts and summarizes the user behavioral needs of parents and children when they use game-based furniture together by using the questionnaire research method, observation method, and interview method. Based on the KJ method, 16 behavioral demand indicators were compiled by five furniture design students to construct a user behavioral demand system. In addition, AHP and entropy weight method were used to solve the user behavioral demand weights from subjective and objective perspectives in this study. Twenty experts and designers in this research field scored the indicators two by two and solved the subjective weights of user behavioral requirements according to the AHP algorithm. A seven-level Likert scale was used to design the questionnaire and distribute it to the parents of children aged 3–6 to fill in, and the 121 valid questionnaires obtained were used as raw data for entropy weighting to obtain the objective weights of user behavioral needs representing the opinions of interactive game-based furniture users. Finally, with 0.4 as the proportion coefficient of subjective weights, the subjective and objective weights were weighted to get the comprehensive weight value of each demand. The results show that the eight items with higher weights for user behavioral needs include: firm and stable, safe in use, comfortable for both parents and children, holding behavior by human-machine dimensions, able to sit on the ground and play, able to play face-to-face, easy to find for picking up, and sufficient operating space. In general, parent-child interactive game furniture firstly needs to meet the user’s needs for safety and comfort, and secondly needs to meet the user’s needs for the state of the game posture and the furniture size to meet the needs of the fetching and storage posture and the game space. The fuzzy comprehensive evaluation model established based on these needs can take into account the opinions of design experts and users at the same time and put the needs of children and parents in an equally important position so that the design of children’s play furniture can tend to meet the needs of parents and children when they use it together, and to promote parent-child interaction and the healthy growth of children.
