Concepção de Artefatos Digitais (CAD)

CIN0131 is the digital product design course at CIn, taught by Alex Sandro Gomes. Giordano Cabral took part as second professor in the three semesters following the postdoctoral period, with the engagement content (the reason someone would return to using the product) and the corresponding gamification repertoire: Octalysis, by Yu-kai Chou, and the "Fourteen forms of fun".

Three co-taught editions: 2024.2 (40 hours by Giordano Cabral), 2025.1 and 2026.1 (20 hours each).

A four-stage design thinking process, each with a formal submission: empathize and define (immersion, interviews, personas, competitor analysis, a review of current research and technology); ideate; create low-fidelity prototypes and storyboards; evaluate usability. The final submission is a video of up to ten minutes covering all stages, so that each student's contribution can be reviewed. Readings range from IDEO's Design Kit and Stanford's HCI classes to the literature on persuasive design; in 2025.1, AI tools for secondary research (Scite, Elicit, Consensus, Perplexity).
