Physical participatory system for Lambeth Council / Digital / Service Design / User Experience / User-centred Design
November 2016

I worked with students coming from multidisciplinary backgrounds into solving a real world design problem for the Lambeth Council in London, one of the most multicultural and diverse areas in the city and in England.

Lambeth is currently going through major changes that bring positive and negative reaction from their population. The council provides online open data to inform their residents, however fails in making it accessible and easy to understand for a wider population.

The design challenge was focused into generating a technological approach that could help the Lambeth residents become informed about the changes happening in their neighbourhoods, as well as providing suitable feedback from the residents for the Council to analyse in order to take action.

My group and I conducted a User Centred Design approach focused in ethnicity centred areas of Lambeth impacted by controversial development projects. This approach involved understanding about the council and the borough on one side, and on the other conducting User Research by interviewing 26 residents living close to these projects. From this approach we could condense people’s perspectives into 4 main personas to design for.

From the main requirements researched, my group and I brainstormed ideas about possible design solutions in communication between the council and residents, conducting storyboard evaluation with 16 users and upon iteration and refinement of ideas we conducted 20 mockup evaluations. This research allowed designing the Lambometer, a network of easy to read contextual data and feedback devices installed on traffic lights poles around specific areas of Lambeth.

The feedback received from residents is sent wirelessly to an open source digital platform for the community and council members to consult and use. These would be deployed in specific places of Lambeth, during a specific amount of time. The data sets and devices can be customised as well.
Placing them on traffic lights takes advantage of the queuing time of passers-by.

This project was presented to a member of the Lambeth Council and received an excellent feedback and enthusiasm around the idea, specially the mix between physical, digital and online connectivity.
