The Story

A Large Group of Friends, or a First Date?

A Large Group of Friends, or a First Date?

Our branded tabletop experience "Serenitea", subtly informs guests of social behaviors based on the position and movement of their teacups.

This table top responds in real time based on various inputs from tea cups on the table.

Primary Interaction

Learn Your Tea's Cultural Origins

Learn Your Tea's Cultural Origins

Customer interviews revealed a lack of interest in discovering new types of tea despite a selection of over 100+ types.

With a diverse selection of tea, an introductory interaction celebrates the origins of each. Guests feel more encouraged to try different teas to gain more mini cultural narratives.

Passive Interaction

Using computer vision, the projected pattern responds to the movement of tea cups by turning towards it.

Passive Interaction

Make Ripples When Teacups Move

Make Ripples When Teacups Move

Our team observed social behaviors around the movement of tea cups, such as how guests place cups when they are actively socializing versus a lull in the conversation.

Micro Interactions

A series of subtle shifts in pattern that inform the real-time input of guests around the tea table.

Audio Input

As conversation flows around the table, a slight color change occurs to indicate the sides with more volume

Lifting and Placing Cups

While taking sips, ripples occur when cups are picked up and placed down onto the table.

Stationary Cups

When your cup rests on the table, it will "sink" over time, with the pattern moving out and away from the cup.

Proximity

You might sit closer to a friend, or trade drinks. A blossom appears when cups are close.

Visual System

Distilling Brand and Complementing Space

Distilling Brand and Complementing Space

The mosaic waterlily motif represents the brand essence of the tea shop, and complements its geometric interior design.

User Journey

Designing for Different Stages of Emotion

Designing for Different Stages of Emotion

Based off of customer interviews, mapping interactions, their modality, and emotional journey over a typical guest experience.

Tech Diagram

How it Works

How it Works

The tech system implements a camera, computer, and projector to track tea cup location, send location input, and manipulate the animation

Process Snapshot

Making it Work

Making it Work

A main struggle we had was creating a surface that was transparent enough to detect the cups, but opaque enough to see the projection clearly.

We also iterated several versions to create burst animations that were both concise and informative.

Reflection

Creating a Branded Physical Artifact

Creating a Branded Physical Artifact

I enjoyed the process of designing a branded interactive experience, with focus on maintaining visual consistency and interviewing customers to define interactions to reflect.
