I worked with an HCI team to investigate and design a mobile version of PICOLA (Public Informed Citizen On-Line Assembly). PICOLA is an extension of James Fishkin's idea of deliberative polling, in which stakeholders in a public policy or political issue are brought together to make informed decisions through deliberation and dialog. Mobile PICOLA's goal is to make this delibration much more accessible by using mobile devices and video. After affinity diagramming to identify our foci, we studied and modeled how people communicate remotely using Contextual Inquiry on teleconferencers - as an example here is our consolidated Flow Model. Using these models, we paper-sketched what a mobile interface would look like, iterating from lo-fi sketches to medium fidelity ones and then to hi-fi, detailed layouts with which we did KLM (Keystoke Level Modeling), Heuristic Evaluations, and Thinkaloud testing. Our final deliverable was a working Flash version (screenshots 1, 2, 3) of the Mobile PICOLA interface, which was handed off to the project's developer to be implemented on Pocket PC devices under a Microsoft grant. The work was presented at ACM's MobileHCI '06. Our summary of the redesign is here.
