Art Tee Vending Machine

Insight

Study on the interaction design for an art T-shirt vending machine with a 7'' touch screen


Idea

Who
Commuters, people looking for a quick purchase, quick present or a replacement for a dirty or broken shirt
People killing time in an a waiting area (i.e. train platform)

Where
Public space, probably an area of high activity (i.e: train station, night club)
Requires very fast interaction, the steps for a purchase shouldn't be more than 3: choice, payment and collection
The payment issues are the usual for a public space: providing privacy for credit card payments and a mean of checking the surroundings (i.e. covered keypad and mini security back mirror)

How
The interface must encourage exploration and discovery
Quick and easy way to browse the catalogue in which the key elements are: design, gender, colour and size
Immediate error recovery and return to previous steps
A 7 inch screen is small to medium size: no overload with content, no fancy 3D or rotation effects that can also deviate the user from a quick purchase
The design must provide quick yet playful experience and the possibility to continue the purchase online if the waiting time is interrupted (i.e. train arrives)

Scenarios
Idle and Initialisation: the screen acts as an attractor loop
