 Brief bio:

 

Indrani Medhi Thies is a Researcher in the Technology for Emerging Markets Group at Microsoft Research India in Bangalore. Her research interest is in the area of User Experience Design, and Technology for Global Development. Her primary work has been in User Interfaces for Low-Literate and Novice Technology Users. Indrani has a Masters degree in Design from Institute of Design, Illinois Institute of Technology (IIT-ID), Chicago, USA. Currently, she is also a 5th year Ph.D. candidate at the Industrial Design Centre, Indian Institute of Technology, (IIT Bombay), India.

In 2010, Indrani was listed in the Massachusetts Institute of Technology-Technology Review’s MIT TR35 2010 world’s top 35 innovators under the age of 35; featured in the list of "50 Smartest People in Technology" by Fortune magazine; and won the "Young Indian Leader" award from CNN IBN.

Indrani was born and raised in Guwahati, Assam, and has been living in Bangalore since mid 2005.

 

 Projects

 

 1) UIs for Low-Literate Users

 

  

One of the greatest challenges in developing Information and Communication Technologies for global development is that 41% of the population in the least developed countries is non-literate (UNESCO 2007) and even the literate among the poor are only novice users of technology. “Text-Free UIs” are design principles and recommendations for computer-human interfaces that would allow a first-time, non-literate person, on first contact with a PC or a mobile phone, to immediately realize useful interaction with minimal or no external assistance. Through an ethnographic design and iterative prototyping process and rigorous user evaluations, involving more than 700 hours spent in the field and 570 study participants from low-income, low-literate communities across India, the Philippines and South Africa, we established design principles that use combinations of voice, video and graphics (ToCHI’11, CHI’09). We have applied these principles to designing three PC and mobile phone-based applications:

- Job-search for the informal labor market (CHI’08, ITID’07)

- Health-information dissemination (WWW’07)

- Mobile-phone-enabled banking and payments (CHI’09, HCII’09).

Rigorous user evaluations with test participants confirmed that our non-textual designs were strongly preferred over standard text-based interfaces and that first-time, non-literate users were, in fact, able to navigate through our UIs meaningfully (ToCHI’11, ITID’07).

We have also observed that non-literacy is not just about the inablity to read, but seems to be coorelated with a variety of cognitive skills, such as ability for transfer of learning and understanding hierarchical navigation. In current work we are studying design implications for UIs for low-literate users given their cognitives skills (CHI'13, ITID'12).

 

2) VideoKheti

 

VideoKheti (CHI'13, DEV'13) is a multimodal video search system for low-literate farmers that combines local language speech, graphics and touch interaction to help find and watch agriculture extension videos (of digitalGreen), in the farmer's own language and dialect. We investigate if the complementarity of speech, graphics and touch lead to a better experience for low-literate and novice users? And if it is even worth the extra cost in engineering (to build automatic speech recognition) and bandwidth for sustained use? Among other things results from our usability studies show that speech works best where there is a long list of choices and selections comprise of short familiar words and expressions. A video demo here.

 

3) Mobile Data Collection:

 

In rural settings within developing countries where digital devices are not pervasive, all written records are maintained on paper forms which take a long time to aggregate and process data, resulting in corresponding delays in remedial action. We study this problem in the context of malnutrition treatment of rural children in Madhya Pradesh through ethnographic interviews and contextual inquiries, and present a health data record management application on a low-cost digital slate prototype (UX'12) built through iterative prototyping. The solution directly accepts handwritten input on ordinary paper notebooks placed on the digitizing pad of the slate, and provides immediate electronic feedback on the display of this device. This simultaneously generates a paper and digital record of the data. The digital slate’s micro SD card can be transferred to a mobile phone and the data sent to the backend database via GPRS. The server is updated at the end of each day, and the summary of the data is made available to the decision makers.

We also conduct a case study of dimagi's CommCare (NordiCHI'12), a health data collection and record management system deployed on low-cost mobile phones. Through a three-month unsupervised field trial in rural Madhya Pradesh with ten health workers we report data management gains in terms of data quality, completeness and timeliness for 836 recorded patient cases, and demonstrate strong preference for the system by rural health workers.
