Background and Context
As part of an internal playtest for an upcoming multiplayer Nintendo Switch party game, the development team identified potential usability challenges for younger players, particularly those aged 4-8. While the game is designed as a social experience where children can learn through observation and guidance from parents or other players, concerns emerged about whether the tutorials and motion controls were intuitive enough for this age group.
The producer and game designers requested a clearer understanding of these issues to determine if usability improvements were necessary before release.
Target Audience: Children (4-8 years old) & Young Adults (9-18 years old)
Research Objectives
The primary questions guiding this study were:
Are there usability issues for young children (4-8 years old) when playing the game?
How do children perceive and interact with different game modes (RPG vs. Party Mode)?
What improvements can be made to tutorials, motion controls, and AI behaviors to enhance the experience?
My Role and Methodology
As the Project Owner, I reported directly to the Game Project Manager and was responsible for:
Research planning and study design
Participant recruitment and coordination
Conducting observations, interviews, and data collection
Analyzing findings and deriving actionable recommendations
Presenting results to stakeholders for implementation
Methodology
To understand young player behavior accompanied by his or her parents , we employed a mixed-methods approach combining observation, interviews, and questionnaires.
The playlets session is about 1h, starts with the presentation of game, then gameplay for 40-45min and ends by a questionnaire for parents. All sessions are filmed with permissions.
Participant Recruitment
We recruited six families in Shanghai through screening questionnaires. Families were selected based on criteria that included at least one parent working in the gaming industry, with preference given to households where both parents worked in related fields.
Key Findings and Insights
Tutorial Clarity and Simplicity
Issue: Children, especially those under eight, found the initial tutorials overwhelming.
Evidence:
Many players skipped instructions entirely, relying instead on trial-and-error approaches
Parents frequently had to explain basic mechanics multiple times during sessions
Younger children showed visible frustration when confronted with text-heavy instructions
Recommendation: Simplify tutorials by using visual-only cues with minimal text. Introduce interactive onboarding with guided mini-games before progressing to full gameplay.
Motion Control Usability
Issue: Motion controls using the Joy-Con controllers proved too complex for young children.
Evidence:
Frequent incorrect inputs were observed (for example, swiping instead of tilting)
Controls often didn't respond as expected, leading to repeated failed attempts
Children frequently looked to parents for assistance with basic motions
Recommendation: Adjust motion control sensitivity specifically for younger players. Implement a training mode with gradual difficulty progression to help children build confidence with the controls.
AI Behavior and Engagement
Issue: Artificial intelligence characters were either too aggressive or underutilized in the gameplay experience.
Evidence:
Some AI opponents defeated child players too easily, causing immediate frustration
Other AI characters weren't properly introduced, making them feel irrelevant to the gameplay
Children showed confusion about the role of AI characters in both RPG and Party modes
Recommendation: Balance AI difficulty by implementing adaptive difficulty that adjusts based on player skill level. Improve AI storytelling by giving characters clearer roles and better introductions in Party Mode.
Actionable Takeaways
Based on these findings, the team should prioritize:
Redesigning tutorials to focus on visual simplicity and interactive learning
Optimizing motion controls specifically for younger players through sensitivity adjustments
Refining AI behaviors to balance challenge and engagement appropriately
Testing improvements with children first in future iterations to validate changes
Conclusion
While the game is designed as a social experience where children can learn from others, clear usability barriers still exist for younger players. By simplifying tutorials, improving motion controls, and refining AI behaviors, the game can become more inclusive and enjoyable for its full target audience.
