Abstract: 

While mobile phones have found broad application in reporting health, financial, and environmental data, there has been little study of the possible errors incurred during mobile data collection. This paper provides the first (to our knowledge) quantitative evaluation of data entry accuracy on mobile phones in a resource-poor setting.

Via a study of 13 users in Gujarat, India, we evaluated three user interfaces: 1) electronic forms, containing numeric fields and multiple-choice menus, 2) SMS, where users enter delimited text messages according to printed cue cards, and 3) voice, where users call an operator and dictate the data in real-time. Our results indicate error rates (per datum entered) of 4.2% for electronic forms, 4.5% for SMS, and 0.45% for voice.

These results caused us to migrate our own initiative (a tuberculosis treatment program in rural India) from electronic forms to voice, in order to avoid errors on critical health data. While our study has some limitations, including varied backgrounds and training of participants, it suggests that some care is needed in deploying electronic interfaces in resource-poor settings. Further, it raises the possibility of using voice as a low-tech, high-accuracy, and cost-effective interface for mobile data collection.

Abstract: 

The  usage  of  mobile  phones  is  abundant  in  our  daily  lives  in  various  aspects from making phone calls or sending text messages to checking e-mails or news updates to planning our activities or managing our budget. This project aims at making use of this wide spread usage of mobiles to help in the  data  collection  process.  It  designs  and  develops  a  web  based  system  called “MobiCollect”  that  is  used  for  creating  forms  or  questionnaires  to  be  later accessed  by  the  data  collectors  using  their  mobile  phone  web  browser  in  order fill in the form with the appropriate data. 
 
Once  the  system  design  and  implementation  is  completed  it  will be  tested  and evaluated to ensure the satisfaction of at least the minimum requirements of the proposed system.

Abstract: 

The FCC conducted a survey of 5,005 Americans in October and November 2009 in an effort to understand the state of broadband adoption and use, as well as barriers facing those who do not have broadband at home. Pages 21-23 contain data about mobile usage.

The report indicates that 86 percent of American adults own a cell phone, and 30% use their devices to access the mobile web. In contrast, 66% have sent or received text messages. The numbers are higher for minorities; 36% of African-American and Hispanic users use their devices to access the mobile web. There is also a generational gap; 48% of those 19-29 access the mobile web, compared to only 5% of those over 65.
