Book Worm Case Study: On-Demand Book Printing Kiosk

Book Worm is a high-fidelity university group prototype for a public book-printing vending machine. The concept allows users to browse a catalogue, customize print options, pay through multiple methods, and collect a freshly printed book in a public setting.

Problem

A kiosk in a station, airport, or other busy public space needs to support quick decisions, accessible navigation, clear error recovery, and confidence around payment and order status. The design challenge was to make a complex custom-printing workflow feel simple for first-time users.

Role

As a Developer on the group project, I contributed to the interactive prototype, user-flow design, technical presentation, and evaluation work that helped validate the interface concept.

Architecture

User Flow: Browse, search, scan, customize, pay, and track print status from a single public kiosk interface.
Personalization: The concept explores recommendations and recognition flows for returning users.
Physical Prototype: A 3D model and AR placement helped communicate how the kiosk could work in a real environment.
Evaluation: Heuristic review and SUS-style usability feedback informed the final design direction.

Stack

Figma interactive prototyping, 3D modelling, AR presentation, user-centered design methods, heuristic evaluation, and SUS questionnaire analysis.

Media

The project page includes the main kiosk image, AR and 3D model screenshots, additional interface visuals, and a full-width prototype video in the media gallery.

Outcome / Impact

Book Worm demonstrates practical UX thinking for public interfaces: accessibility, queue visibility, payment clarity, and prototyping beyond a flat screen. The result is a detailed concept supported by interactive design and evaluation evidence.
