15 Jan, 2015 : Lecture on Design thinking for affordable and frugal innovations by Prof. Tapan Parikh from UC Berkeley

Date: 15-01-2015

Time: 15:00 - 17:00

Venue: Wing-11, IIM Ahmedabad

Representation Technologies Information technologies are essential tools for the representation and communication of human knowledge. However, many groups are still inadequately represented on the Internet. My research group developed Avaaj Otalo, a phone-based voice message board allowing small farmers in rural India to ask, answer and browse agricultural questions and answers. Avaaj Otalo has been deployed for over four years, and receives hundreds of calls every week. I report on recent results from this deployment, including evidence of impact on farmer decision-making, reducing the use of less effective and potentially harmful pesticides, through a randomized controlled trial (RCT). While Avaaj Otalo illustrates the importance of designing appropriate user interfaces for representing knowledge from underrepresented groups, knowledge must still be translated to structured, quantitative forms for aggregation and policy decision-making. Local Ground is a data collection, mapping and information visualization tool that helps youth develop data skills by making connections between different representations of empirical phenomena. Students begin by collecting open-ended qualitative data, in the form of free-hand drawings, pictures and audio interviews. Based on these observations, students can design of structured data collection instruments for more systematic inquiry and analysis. These various forms of data are combined into narratives that can articulate youth perspectives to a variety of stakeholders. Local Ground has been used to involve youth the planning of a public park, ground-truth civic data about food access, and document air quality issues across the BART transportation system. Within these projects, I explore several themes in my work, including the design of more accessible interaction techniques allowing new populations to author content, the importance of bottom-up data for planning and valuating development projects, and how we can employ participatory computing technologies to improve learning and human agency.

Bio of Prof Tapan Parikh: Tapan Parikh is an Associate Professor at the School of Information at the University of California, Berkeley. Tapan's research interests include human-computer interaction (HCI), mobile computing, paper and voice UIs and information technologies for education, governance and international development.
