This paper presents a study of mobile data usage in South African townships. In contrast to previous studies, which have studied mobile data usage in developing regions (including South Africa), we focus our study on two townships in South Africa; the extremely resource-constrained nature of townships sheds light, for the first time, on how people in these communities use mobile data. We perform a mixed-methods study, combining quantitative network measurements of mobile app usage with qualitative survey data to gain insights about mobile data usage patterns and the underlying reasons for user behavior concerning mobile data usage. Due to the limited availability of public free Wi-Fi and despite the relatively high cost of mobile data, we find that a typical township user's median mobile data usage is significantly more than Wi-Fi usage. As expected, and consistent with observations of mobile data usage in parts of South Africa with better resources, users tend to favor using Wi-Fi for streaming video applications, such as YouTube. Interestingly, however, unlike users in less resource-constrained settings, township users also consume significant mobile data to update mobile applications, as opposed to relying on Wi-Fi networks for application updates. These behaviors suggest that network and mobile application designers must pay more attention to data usage patterns on cellular networks to provide mobile network architectures that provide more cost-effective mechanisms for tasks such as application update.

The pandemic of lifestyle-related chronic diseases has led to an advent of personal health informatics, often using mobiles and gamification to persuade individuals to adopt healthful lifestyles. However, this approach can constrain benefits to younger, more technically literate beneficiaries, despite the higher need for PHI in older populations. In prior work, we proposed that children in the household aid in reaching beneficiaries, targeting intermediated use. This study compares the use of two versions of a nutrition and exercise monitoring app in 14 households. One supported logging and occasional SMS reminders while the other added gamification elements. We measure self-determination with respect to each version using pre- and post-tests, also drawing on observation and interview data. Our findings suggest that virtual rewards can enhance use of such systems through intermediaries, via benefits such as increased perceived competence. We highlight the challenges and design implications involved in fostering engagement in our system.

In recent times, migrating from touch-based input devices to touchless input devices has become one of the major research problems considering the health hazards exposed in public usages (e.g., information kiosk) of the touch-based devices. The problem still remains mostly open, since a solution having the properties of being low-cost, low power consuming, robust, and easy-to-use, is yet to be proposed in the literature. As a remedy to this situation, in this paper, we propose a visible light based touchless input device (named Sporshohin), retaining all the properties mentioned above, for ensuring ubiquitous usage. Sporshohin recognizes predefined gestures performed by the user, through an underlying mechanism that exploits well-known reflection model over the visible light spectrum. The underlying mechanism is intelligent enough to guarantee robustness against varying environmental lighting conditions and undefined noisy gestures. Real implementation, involving interaction with diversified users, confirms high accuracy and usability along with existence of all the above mentioned properties. We show the emulation of Sporshohin as an input interface for an information kiosk. The attributes of Sporshohin exhibit its prospect of being used in diversified applications going beyond information kiosks.

Cutting edge communication technologies such as smartphones remain far from prevalent in most of the settings with the greatest need for improved health and development programs. As a result, designers of ICT4D initiatives often weigh difficult tradeoffs between the usability of smartphone applications for structured data collection versus the battery life, durability, cost and familiarity of basic phones. However, as this paper and our deployment experiences demonstrate, such tradeoffs are not always necessary. Most mobile network operators in sub-Saharan Africa offer value added services via simple, menu-driven applications that run directly from the SIM card. While conventional SIM applications can only be accessed by mobile network operators, this paper describes the design and implementation of a 'thin SIM' approach that does not require mobile network operator involvement. We have implemented this tool with more than 3,000 health workers and describe particular deployment experiences in Kenya, Benin, Nepal and Guatemala. We then reflect on a number of important limitations of the thin SIM approach, and opportunities for further development and deployment. Ultimately, we argue that there is an important role for SIM applications as one part of a configurable data collection toolkit for supporting global health and development programs.

Recent rise in aged population and chronic diseases, is placing increasing pressure on health care expenditure. Ubiquitous health care is regarded as a potential driver in reducing such health expenditure. Advancement in wireless communication and sensor technologies permits real-time acquisition, transmission, and processing of critical medical information for ubiquitous health-care applications. Hence, medical body area networks (MBANs) emerge as a key technology to facilitate ubiquitous health-care services. However, energy restriction of micro-battery of a sensor device holds back the development of MBANs and also makes MBANs vulnerable to different malicious attacks. In this paper, we introduce a new attack entitled Power Attack exploiting power constraint of the sensor devices. Power attack forces a sensor to die off due to lack of power supply. Besides, we also propose countermeasure for the presented power attack. Finally, we exhibit efficacy of our proposed countermeasure using experimental evaluation.

This paper argues for a virtual tech hub design ontology which would be the closest representation of the tech-innovation ecosystem. Many physical tech hubs seek to bring to one place actors and agents within the tech-innovation ecosystem. The tech-innovation ecosystem has been a primary aspect of discussion around the success or failure of many tech innovations in developing countries. Existence of an enabling ecosystem which absorbs and sustains technology innovation solutions is necessary. The question of understanding appropriate technology context as ecosystem has led to many approaches and definitions, many of which have the limitation of focusing only on a given aspect rather than the whole ecosystem of actors and their inter-relations. The paper addresses and proposes a definition of the tech-innovation ecosystem, and proposes the use of the virtual tech-hub as a useful tool to measure the intensity of tech-innovation. Starting from the premise that each locale presents its own unique physical ecosystem, this paper proposes a method of representing that ecosystem in the virtual sphere through ecosystem virtualization and representation. The virtual tech hub will be the ultimate hub without limitations of space, access or tenancy. It shall allow for uninhibited engagement of innovators and ecosystem enablers and stakeholders. The virtual hub can help policy makers to correctly measure actors and their interactions, and effectively accelerate ecosystem development, through focused intervention. This paper describes a virtual hub which attempts to achieve an entire ecosystem virtualization by offering through a single window, a collaborative integrated platform.

Homelessness is a large problem in the United States. One of the best solutions for this large population of unsheltered individuals lies in affordable housing, as it allows for individuals to gain substantial footing on a life free from poverty in a safe environment. However, affordable housing complexes are not only very scarce, but also the organizations that own them do not communicate frequently. Because of this, application windows are scattered and the housing applications are extremely fragmented, with each application containing different questions. Our team has designed a mobile solution in collaboration with Catholic Charities to simplify the process of finding and applying to affordable housing in Santa Clara County. The Android application allows users to find affordable housing and apply to any number of housing complexes with one unified application that combines questions from individual applications.

The rise in the number of deaths in Bangladesh owing to different female genital cancer, specifically ovarian cancer, emphasizes the need of having effective measures to aware women, specially the rural women about the prevention of ovarian cancer. Therefore, in this paper, we propose a mobile phone based application called Prottasha to provide diversified services regarding ovarian cancer for rural women of Bangladesh. Prottasha will provide a potential prediction on the risk of having ovarian cancer based on different demographic characteristics such as age, marital status, and the presence of common symptoms, exploiting efficient and effective data mining techniques. We also propose a model for low cost portable ultrasound scanner, which allows the rural women to have frequent screening at their home.

This paper presents an application designed for interfacing the farmers and the communications and control systems when automated irrigation is used. The proposed application allows visualization and compilation of the data collected by the sensors used in a smart agriculture system. The objective is to minimize the farmers' direct interaction with the technical apparatus. It also aims to allow the farmer or an authorized third party to modify the irrigation parameters without knowledge of the irrigation hardware system, given them control back of the irrigation when required. In this design, GSM communications networks are used due to their widespread implementation in developing countries, their extended coverage and relatively low cost in these countries.

Twitter has largely become a central online social network for arguments on various global controversial topics. Detecting and analysing such topics could prove to be beneficial in understanding the sentiments of trending topics in developing regions. In this paper, we perform a systematic sentiment study of trending controversial topics on Pakistan's Twitter user-base. From the data collected we build retweet graphs, partition graphs into communities, measure community influence, and label the communities as 'for' or 'against' per topic. To the best of our knowledge this is the first work to categorise and study sentiments attached to controversial topics in a developing region.
