Problems:
Coffee consumption on the go increasingly relies on self-service. Starbucks-style chain outlets make us stand in line to order; our workplace cafeteria requires us to operate an automated machine. While this optimizes the process for the organisation who sell the coffee, for the consumer, it becomes ever more tiresome. We spend longer queueing, are under pressure to speed up our order, and know very little about the product they will receive. This amounts to a dissatisfactory user experience, one which falls far short of traditional café service.

Idea:
Coffee Composer puts the fun back into self-service. This service design concept enriches the interaction for consumers, making the most of what humans do best: the creative and tactile parts of the process. A range of color-coded ‘tokens’ symbolize possible ingredients (such as milk and sugar), offering users greater transparency and autonomy to choose what ends up in their coffee. A glass cup makes it easy for users to comprehend the custom combination of ingredients as they are dispensed.

The selection process begins earlier, meaning queue time is used more effectively, as customers get to pick and stack their preferred elements to create their ideal hot beverage. The automated coffee machine intuitively ‘reads’ their order, converting each token into its corresponding ingredient in consecutive order. The communication between the automated machine and human user becomes more subtle and enjoyable.

Coffee Composer demonstrates that increased automation need not result in a banal and laboured interaction between user and machine - it should instead free us humans up to pursue activities we enjoy.

User Flow

Ingredients Module System


This modular system is considered to be scalable depending on diffenrent preference, region and various coffee culture.
Milk
Almond Drink
Soya Drink
White Sugar
Brown Sugar
Espresso
Foam
Hot Water
Oat Drink
and so on...



Each module represents an ingredient and has a bold-style graphic logo on it. The sideview of the modules visually makes the ratio between different ingredients much stronger. The color code serves as a supporting hint to help people recognize what module it is. They have different heights of 3mm, 5mm and 9mm.

Choosing Process


The choosing process starts earlier as soon as people join the queue. With a playful choosing experience, it makes waiting time seem shorter.

She chose 2x Milk and 1x espresso, the ratio is 2:1 (milk to espresso)
It might taste similar as cappuccino

Interacting with Machine


The machine starts to recognize the cup as soon as you take it.
The breathing LED light gives you a hint where to put your cup and modules. The biggest cup would be suggested to place onto the lowerst platform while the smallest cup will be suggested to the highest platform.
By placing the modules onto the surface, it can recognize the type and amount of the modules. In the end it maps the ratio into cup's volume.

An embedded NFC sticker makes it recognizable
