We report a deployment aimed at employing voice-based, telephone services to conduct automated, structured interviews of low-literate users and to advertise relevant development-related services to them. Survey calls were placed to 67,000 vocational training recipients to validate their phone numbers and to find out their current job status. Of these, 45,500 answered these calls and 11,500 (25%) responded to the survey questions. Manually conducted follow-up interviews found more than 70% of the survey results to be consistent and also revealed the impact of phone sharing (among family members), call timing, simplicity of interface and surveyor-participant interpretation mismatch regarding certain survey questions on participant involvement and the validity of survey results. The paper discusses the use of IVR to collect information, possible system design considerations and factors affecting the accuracy of gathered information.","PeriodicalId":204042,"journal":{"name":"Proceedings of the 7th Annual Symposium on Computing for Development","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130953069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their interactions with the technology are explicitly and implicitly affected by their political, cultural, infrastructural and socio-economic environments. In this poster, I present findings from ongoing sets of interviews with eGranary intermediary donors and agents, operating in ten sub-Saharan countries. eGranary is an offline library collection of open-source Web material, designed for use in environments with irregular or no Internet connectivity. However little is known of the ICT's impact on communities, users' knowledge practices, or its wider effects, e.g. on pedagogy. Prior to establishing communications with end users, this study takes a preparatory step of consulting with Mediators in the field. These interviewees are familiar with eGranary's technology and their users' contexts, expectations and needs. Findings from this research will better inform the structure, content and tone of planned future communications and questionnaires.","PeriodicalId":204042,"journal":{"name":"Proceedings of the 7th Annual Symposium on Computing for Development","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133824273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We combine energy-efficient hardware acceleration optimizations with algorithmic tuning of signal processing and machine-learning routines to deliver a platform for insect classification. The use of low power accelerator blocks in cheap embedded boards such as the Raspberry Pi 3 and Intel Edison, along with performance tuning of the software implementations enable a competitive implementation of mosquito classification task on standard datasets. Our approach demonstrates a concrete application of embedding intelligence in edge devices for reducing system-level energy needs instead of simply uploading sensory data directly to the cloud for post-processing. For the mosquito classification task, we are able to deliver classification accuracies as high as 80% with Intel Edison processing times as low as 5 ms per set of 8K audio samples and an energy use of 5 mJ per sample (2 months of continuous non-stop use on an AA battery with 2000 mAh capacity or longer depending on insect activity). We envision a network of connected sensors and embedded/IoT platforms deployed in vulnerable such as construction sites, mines, areas of known mosquito activity, ponds, riverfronts, or other areas with standing water bodies. In our experiments, targeting a 20% packet loss rate, we observed the ad-hoc WiFi range for mesh networks using the Raspberry Pi 3 boards to be 14 m while the Photon board connecting to infrastructure WiFi router nodes can stretch this to 35 m.","PeriodicalId":204042,"journal":{"name":"Proceedings of the 7th Annual Symposium on Computing for Development","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134379064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Projects and systems are frequently based on the Arduino framework, examples include ODK's FoneAstra [3], the Open Energy Monitor [7], and the Grove system of sensors [5]. The Arduino platform is targeted because of its ease of use, community support, and low cost as a data collecting device compared to other off-the-shelf sensors. However, there is a need for a framework suitable for microcontrollers that enable ease of integration into other data collection systems. This includes the ability to synchronize data with collection and aggregation devices designed to work offline as well as the ability to track sensors and describe data sources for other machines and users. To address the issue, we propose a solution based on an existing small database usable on the Arduino platform that would integrate into the Mezuri [6] data collection system. The database is designed to fit within the running memory constraints on a microcontroller to store sensor data with relatively few fields per reading on flash media. This framework, with explicit support for metadata, enables users in emerging regions to directly measure physical quantities as well as indirectly measure human behavior in future development projects involving direct sensing. The database can be used by a non-expert. In particular, we investigate the qualities that a technically inclined social scientist would look for when storing such data on microcontrollers. To enable Mezuri integration we will support metadata as a first class object accessible with additional utility functions and native synchronization support.","PeriodicalId":204042,"journal":{"name":"Proceedings of the 7th Annual Symposium on Computing for Development","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123617873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
