啪嗒是专门为视障人士打造的一款实体音乐游戏，包括各种可组合的发声模块和语音评价系统。它有特殊的触觉反馈机制：不同于传统的触觉信号，而是通过磁铁的相互作用力来为视障人士提供一个信号，起到传达信息的作用。啪嗒最具特色的地方在于每个不同的声效对应的都是不一样的模块，用户可以自行选择自己喜爱的音效，组成自己的专属套装。 我们还利用软件制作了一个可以采集音乐重音鼓点的评价系统，可以在游玩时实时做出评价。

     Magmu is an entity music game designed for visually impaired people，including a variety of composable sound modules and voice evaluation systems.Special tactile feedback mechanism: In each module, we appealed a special tactile feedback mechanism to them, which is giving feedbacks through the interaction force between magnets. In this way, we hope it can be easier for our users to get signals through their hands. Modularized music game: Magmu is modularized, which means that different forms of the sound-making module are corresponded to different sounds, users can choose whatever they like and make their own playing set.Voice evaluation system: We use software to develop a system that can catch the pitch and beat of a music, and in the meanwhile give real-time feedbacks in sound.
