TTC Labs - Consent


São Paulo

25th Aug 2017 at Facebook

The context

Latin America is witnessing the emergence and growth of a new species of companies that is transforming its business landscape: Tecnolatinas, technology-based private companies born in the region. Most of them are entrepreneur-driven digital ventures with an international footprint. Many of these are based in Brazil and the country is in a unique place to create the framework that enhances and protects both privacy and its innovation ecosystem.

Draft privacy legislation in Brazil will require that consent is “unequivocal, free, informed and specific” - which creates both a design challenge as well as an opportunity for businesses implementing practical changes to how user experiences will work.

To make the new standard a success we must interpret the new standard in design in an innovative, creative and user-centric way.

The challenge

To design innovative solutions that show how a more innovative approach to consent can both provide more meaningful control for people over their data as well as a better, more contextualized and more fluid user interface.

Who participated

We welcomed experts from a variety of disciplines, including the São Paulo design community as well as public bodies, law practitioners and industry.

What did they say
"Delivering meaningful control over personal data requires co-ordination, communication and understanding between digital citizens and the digital services that they use"

Richard Gomer, Research Fellow on the Meaningful Consent Project at the University of Southampton

What happened?

Below is an outline of the stages and exercises that took place at this Design Jam. For everything that you need to facilitate your own workshop, please follow the links to the relevant part of our toolkit.


On the morning of the Jam, participants were welcomed and Introduced to Design Jamming. They then took part in discovery exercises around stations, including Understand users to explore the role of personas in building empathy, as well as the exercises Design for transparency and Design data-use notices.

On the morning of the Jam, participants were welcomed and Introduced to Design Jamming. They then took part in discovery exercises around stations, including Understand users to explore the role of personas in building empathy as well as Deconstruct transparency and Analyse transparency in context.


Participants were addressed by subject matter experts on how best to design in response to legal principles. Ana Bialer, legal expert, explained the background to data laws and consent rules. Richard Gomer, from the University of Southampton, explored questions around meaningful consent. Chris Downs, from Normally, told a story about requesting his personal data and what it means in today's world.

All participants worked to Identify opportunities by writing How Might We's on Post-Its during these presentations, and these notes were collected by the facilitation team who placed them on the wall of the day, grouping them into key thematic areas. Some of the unique groupings of questions that emerged from this Design Jam included ideas on how might we:

  • be reassuring and empowering?
  • enable scalability?
  • build confidence and empower user choice?
  • design for accessibility?
  • make it educational and enjoyable?
  • ask only for what's needed?
  • demonstrate the benefits of the value exchange?

The discovery phrase also explored criteria to evaluate people's experiences with regulatory controls, based on happiness, engagement, adoption, retention and task success. These criteria prompted design guidelines to provide human-centric controls. For instance, as the experience of consent sets people's expectations, designs should minimise surprises and provide useful information to drive meaningful choices. Design should acknowledge that in-app interactions shape behaviour. And appropriate metrics should be chosen to measure the success of designs.

Ideate & Prototype

After lunch, the wall of the day was reviewed before moving into the Team kickoff. The facilitators Set brainstorming rules and introduced the teams to Sketching ideas.


Each multidisciplinary team focussed on imagining consent-focussed design patterns for different areas of fictional mobile apps:

  1. Kin - Social Media Network - personal sharing
  2. MyMed - Government Medical Services - personal health info
  3. Fanfare - Music - personal taste and preferences
  4. Chariot - Car Sharing - location sharing and tracking travel
  5. Oink - Banking - sensitive personal data and security issues
  6. Mucnhbox - Food Delivery - location sharing


Teams moved from sketching ideas and receiving Feedback from other teams to Building digital prototypes of a single idea. Each team Ceated a pitch, telling the story of their design patterns back to the whole group and receiving Feedback from experts at the end of the day.
