BitBarista
Bitbarista is an internet-connected coffee machine designed to make the hidden data transactions behind everyday devices visible, rather than concealed. Most smart devices work hard to hide their complexity, but this can breed suspicion once people realise data is moving behind the scenes. Bitbarista does the opposite: it displays raw data about coffee-producing countries (climate, politics, prices, working conditions) and uses this to offer four choices for its next coffee supply—best quality, lowest price, lowest environmental impact, or highest social responsibility. Customers pay with bitcoin, and afterwards see how their choice fits into the pattern of everyone else’s recent decisions.
In a study with 42 people, most found the experience increased their awareness of coffee supply chains and made them feel more connected to producers—many said it would change how they thought about purchases even outside the machine. People were generally comfortable sharing data that felt relevant (coffee preferences, buying principles) but uneasy about anything that felt unrelated (phone numbers, social media, bank details).
Interestingly, almost everyone assumed the machine was secretly gathering far more personal data than it actually was, revealing how normalised invasive data practices have become. Most also saw the machine as a passive “conduit” rather than a genuinely autonomous decision-maker.
The key takeaway: making data transactions visible, rather than hiding them for the sake of simplicity, can build trust—even if it means more visual complexity and information that’s usually considered “unnecessary.”
