Book Worm: An On-Demand Book Printing Vending Machine Prototype
As part of a university group project, we developed Book Worm — a high-fidelity, interactive prototype for a public vending machine that allows users to custom-print books on demand.
Inspired by the challenge to create an interface suitable for public spaces like train stations or airports, our solution focused on accessibility, personalization, and ease of use.
Built in response to a detailed user-centered design brief, the Book Worm system enables users to browse an extensive online catalogue, choose book format (e.g., print size, colour or greyscale, hardback or softback), and pay using multiple methods including card, cash, or mobile phone.
Key Project Elements:
- High-Fidelity Interactive Prototype (Figma):
Designed a fully interactive user interface showcasing smooth navigation, accessible design, and support for various user scenarios — including browsing by genre, scanning book barcodes, and receiving personalised recommendations.
- 3D Model with AR Integration:
Created a 3D model of the vending machine and enabled Augmented Reality (AR) placement using mobile devices to simulate real-world deployment.
- Usability Testing & Evaluation:
Conducted both a heuristic evaluation and a System Usability Scale (SUS) questionnaire to assess user experience and interface efficiency, gathering valuable feedback on visibility, control, and error handling.
Highlights & Outcomes:
- Emphasised ease of access for all users, including first-time customers in fast-paced environments.
- Explored user recognition via credit card or mobile number for personalised recommendations.
- Included queue management and real-time printing status updates in the design.
- Delivered a comprehensive prototype backed by testing results and design documentation.
Impact:
Book Worm demonstrated how custom-printing technology can merge physical and digital experiences, offering a practical and innovative solution for public engagement with literature.
The project combined UX design principles, accessibility standards, and AR technology — earning strong feedback for its creativity, functionality, and real-world application.
