The user location information represents a core dimension as understanding user context is a prerequisite for providing human-centered services that generally improve quality of life. In comparison with outdoor environments, sensing location information in indoor environments requires a higher preci...

Federated Learning (FL) is a new technology that has been a hot research topic. It enables training an algorithm across multiple decentralized edge devices or servers holding local data samples, without exchanging them. There are many application domains where large amounts of properly labeled and c...

Stack Overflow is a popular question answering site that is focused on programming problems. Despite efforts to prevent asking questions that have already been answered, the site contains duplicate questions. This may cause developers to unnecessarily wait for a question to be answered when it has a...

Federated learning (FL) is a promising way to use the computing power of mobile devices while maintaining the privacy of users. Current work in FL, however, makes the unrealistic assumption that the users have ground-truth labels on their devices, while also assuming that the server has neither data...

In this paper, we consider a social-aware unmanned aerial vehicle (UAV) assisted mobile crowd sensing (MCS) system for disaster relief networks, and investigate how to recruit suitable UAVs to perform sensing tasks in stochastic and dynamic environments (both UAVs and tasks arrive stochastically). W...

Practices of technology repair in developing country contexts play crucial and often overlooked roles in supporting ICTD goals of access and sustainability. They also constitute complex and neglected sites of technical skill, knowledge, and learning. Building on original ethnographic fieldwork, this...

Mobilized telemedicine is becoming a key, and even necessary, facet of both precision health and precision medicine. In this study, we evaluate the capability and potential of a crowd of virtual workers—defined as vetted members of popular crowdsourcing platforms—to aid in the task of diagnosing aut...

While repair work has recently been getting increasing attention in HCI, recycling practices have still remained relatively understudied, especially in the context of the Global South. To this end, building on our eight-month-long ethnography, this paper reports the electronic waste (`e-waste', henc...

In a mobile crowdsourcing system (MCS), a platform outsources sensing tasks to numerous mobile worker devices. The collected data are analyzed and the processed information is shared among many other interested users. The platform pays the workers for the sensing data and earns money from the users ...

The objective of this study is to explore the factors that are keys for an idea to be implemented on an online crowdsourcing platform. A data set of 320 implemented ideas from My Starbucks Idea – an online crowdsourcing platform – has been analyzed. We find that only one out of 500 users’ submitted ...

Sexual harassment of women in public places (e.g., foot-paths, buses, and shopping malls) of major cities in developing countries is a growing concern. These harassments can happen in various forms ranging from commenting, catcalling, and staring to touching and groping, to attacking and raping. Tho...

This paper presents an analysis of the privacy issues associated with the practice of repairing broken digital objects in Bangladesh. Historically, research in Human-Computer Interaction (HCI), Information and Communication Technologies for Development (ICTD), and related disciplines has focused on ...

The excessive use of speed breakers on national highways distracts vehicle drivers. In addition to that, drivers often can't recognize the appearance of unmarked speed breakers and loose control of the vehicle, causing serious accidents and loss of lives. In the literature, there exist a few methods...
