本文使用心理学用户体验的研究方法，探究影响唱歌水平的因素，并针对在KTV情境中提高唱歌水平提供概念化的歌曲推荐解决方案。 在研究探索过程中，本文使用了情境研究的方法让30名被试分为6组置身于真实的KTV社交情境中。研究者通过参与现场实验研究，观察和记录被试在KTV情境中的表现，并让被试在KTV参与了与唱歌相关的焦点小组讨论研究。（1）在参与式观察研究中，研究者观察记录KTV情境下的用户行为，分析了KTV中不同类型的人群在KTV中的表现，并产出了三类KTV典型用户画像。（2）在焦点小组研究部分，研究者引导被试讨论“影响KTV点歌的因素”和“影响KTV唱歌发挥的因素”两个话题。焦点小组的亲和图分析与词频分析共同得出对唱歌影响最多的是现场的其他参与者、环境氛围和个人能力等。 针对用户研究中发现的目标用户痛点和需求，研究者设计了有测评、推荐与练习功能的KTV社交歌曲推荐的概念产品。设计主要从三个方面帮助用户：1）基于个人声音条件、性格特点和音乐喜好帮助用户选择合适的歌曲；2）为不同的KTV社交目的推荐合适的歌曲；3）帮助练习歌曲提高目标用户自信心。产品吸引力评估问卷的结果表明，研究者设计的产品概念对目标用户及潜在目标用户均有吸引力。此外，根据测评结果和参与情境进行的个性化推荐功能对目标用户的吸引力显著高于潜在目标用户。
