Instagram 应用程序动效设计Instagram Application Motion Design

课程要求在既有移动应用视觉语言中寻找交互反馈机会。项目以当时的 Instagram 界面为基础，选择三个高频动作进行重新设计。

The assignment explored opportunities for better feedback within an established mobile product. Three high-frequency actions in Instagram's 2018 interface were selected for redesign.

在不破坏原有界面识别度的前提下，让刷新、进入上传功能和发布进度更容易理解，并增加连续、具有触感的视觉反馈。

Make refresh, upload entry and publishing progress easier to understand while preserving the recognizable interface and adding continuous, tactile feedback.

动效以“色彩与颜料扩散”为主题：下拉刷新模拟颜料流动，上传按钮通过扩散与收束表现页面切换，上传进度条在完成后扩展为时间线中的新博文。

The motion language uses color and pigment diffusion: refresh behaves like flowing paint, the upload control expands and contracts between views, and a completed progress bar grows into the newly published timeline post.

最终完成三组交互动效演示。原 GIF 已在本档案中转换为静音循环视频，并保留静态封面以支持低动效偏好和加载过程。

The final outcome is a set of three interaction demonstrations. The archived GIFs are presented here as silent looping video with static posters for loading and reduced-motion contexts.
