Design Process

Design Process

​As we are building a product in a relatively short period, we followed the structure of 'Design Sprint':






​Understand Needs

​Given the situation that Global Game Jam was on the weekend right before Chinese New Year, we wanted to create an experience for audience to enjoy the festival vibe; at the same time, we want to use the game format to have more audiences appreciate the culture in a way of 'duality'. Politically, there is a duality happening in around the world; however, for the festivals, we are sharing the same mood.

Main goals of the piece will be: interactive, fun to play, easy to execute, culture-oriented.

​Based on our observation of social platforms, we concluded that filters on social platforms are a fascinating way for audiences to share their experience and emotions with their friends and family; Spark AR is a powerful tool to develop a piece with executable scope within 48 hours. So we narrowed down and aimed our final design product as a piece of AR filter (game).

Ideate and Decide

​We came up with three design ideas:

Considering music is one of the most powerful media to arouse emotional resonance, we decided to further develop the second idea 'Music + Oriental / Western'.


Interaction Built in Spark AR

Prototype from Sketch to High Fidelity

We made a list of possible facial motions (which can be recognized in Spark AR), combined each of them with a music note respectively. Once the user trigger one or more motions, the filter will play the music note(s) and display the notes according to recognization. UI for 'Oriental' vibe is designed with traditional Chinese name of the notes (different from western ones, Chinese only have five as standard).

Testing and Iteration

We conducted a series of testing, got feedback from both team members and 'naive' users, and iterated to finalize the design. One of the major changes is fix the recognition process with programing method, distinguish closing eyes from unintentional 'twinkle' (twinkle would not trigger any interaction)

Art & UI Assets

UI and graphics are done with Adobe Illustrator; 3D models are designed and animated with Maya, textured with Substance Painter (co-work with Eiko).
