Increasing Intelligibility in the Speech of the Autistic Children by an Interactive Computer Game

Autism is a disorder of neural development which affects about one in every 150 kids on average. One of the major complexities regarding autistic children in social communication is the speech disorder. The problems related to speech disorder fall into different categories and unintelligibility in speech is one of them. Although there is no definite medicine or treatment for autism, doctors, therapists, and special teachers can help kids with autism overcome many difficulties by different physical and psychological therapies. In this paper we have demonstrated our newly developed interactive computer game which will be helpful in increasing intelligibility in the speeches of autistic children and can be used as a therapy besides the traditional approaches. During our five months of intervention with the autistic children of Autism Welfare Foundation (AWF) at Dhaka, we checked the effectiveness of this therapy and got some encouraging results.

Learning, innovation, and sustainability among mobile phone repairers in Dhaka, Bangladesh

Acts of technology maintenance and repair constitute important and often overlooked moments in the operation of complex interactive systems. They also provide fresh insight on a series of problems -- innovation, learning, and sustainability -- long core to HCI concern. This paper builds on original ethnographic fieldwork in the repair markets of Dhaka, Bangladesh to advance three basic arguments: first, that repair activities in such locations reveal novel and significant forms of craft-based knowledge and innovation; second, that repair work is embedded in local and transnational flows that connect local practices to global networks and institutions; and third, that taking repair work seriously can cast new light on problems of learning and sustainability in the design and operation of complex interactive systems. We conclude with observations that relate our repair-based findings back to problems in interactive systems research and design.

Residual Mobilities: Infrastructural Displacement and Post-Colonial Computing in Bangladesh

This paper explores discrepancies between the founding assumptions of mobile and ubiquitous computing in the western world, and the starkly different experiences of mobility and infrastructure to be found in many post-colonial environments. Based on a field study of forced mobility and technology use among populations displaced by the Hatirjheel waterfront development project in Dhaka, Bangladesh, we make two basic arguments. First, we point to the partial nature of assumptions around mobility that frame the imagination of mainstream HCI research, and argue that different and heretofore residual experiences of mobility must also be accounted for in post-colonial and other marginal computing environments. Second, we document four forms of infrastructural experience -- dispossession, reconstitution, collaboration, and repair -- that characterize real-world engagements with infrastructure in such settings. We conclude with implications for HCI research and design, and reflections on how HCI researchers might better account for such experiences in their work.

A Computer Game Based Approach for Increasing Fluency in the Speech of the Autistic Children

Autism is a complex developmental disability that typically appears during the first three years of life. This is the result of a neurological disorder that affects the functioning of human brain. Children diagnosed with autism often are self-absorbed and seem to exist in a private world where they are unable to successfully communicate and interact with others. Sometimes they have difficulties in developing speaking skills and understanding what others say to them. Lack of fluency in the speech is one of the most frequently found problems with autistic children. The traditional methods for increasing fluency were found to be monotonous and hence, not much successful during our three months of observations over the participants of Autism Welfare Foundation (AWF) at Dhaka. Therefore, we developed an interactive computer game for the autistic children for improving the fluency in their speech. Our game produced encouraging results over a participant during three months of observation. In this paper, we describe our project and the outcomes.

Learning to fix: knowledge, collaboration and mobile phone repair in Dhaka, Bangladesh

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 paper explores the explicit, tacit, and social knowledges that shape practice and expertise in the mobile phone repair markets of urban Bangladesh. We document forms of learning and collaboration central to the production and innovation of repair skills and knowledge, and show how these processes operate at the intersection of global knowledge flows and local efforts to access, contextualize and situate that knowledge. We conclude by arguing for repair as an underappreciated site of third-world technical practice and expertise, and reflecting on how ICTD research might better take such practices into account.

Refugees and HCI SIG: The Role of HCI in Responding to the Refugee Crisis

The recent refugee crisis has escalated and expanded in to a global challenge. In their flight from hostility, refugee populations face challenges in accessing services that are often compounded by political and social tensions. The urgency and complexity of the situation calls for HCI researchers to contribute to the management of this crisis. This SIG aims to bring to the surface the challenges faced by refugees and elicit the experiences of the authors. It also calls for forming a collaborative network of researchers that have an interest in innovatively addressing issues surrounding refugee populations.

Teaching intelligible speech to the autistic children by interactive computer games

Autism is considered to be a disorder of neural development which affects about 1 in every 150 kids. Specifically, some children with ASD are not fortunate enough to acquire the ability to communicate in their own language. Since speech is an important media of communication, socialization, and interaction with the world, these children need assistance while delivering speech to communicate to the world. Without proper speaking skills, these autistic children face difficulties in expressing their needs and emotions, too. Doctors, therapists, and special teachers usually help kids with autism to overcome many difficulties. However, the traditional methods of teaching clear speech to the autistic children suffer from being monotonous, laborious and not successful in many cases. Hence, we developed an interactive computer game which will be helpful to increase intelligibility in autistic children. During our five months of intervention with the autistic children of Autism Welfare Foundation (AWF) at Dhaka, we checked the effectiveness of this therapy and got some encouraging results.

Cutting a Cornered Convex Polygon Out of a Circle

The problem of cutting a convex polygon P out of a piece of paper Q with minimum total cutting length is a well studied problem in computational geometry. Researchers studied several variations of the problem, such as P and Q are convex or non-convex polygons and the cuts are line cuts or rays cuts. In this paper we consider yet another variation of the problem where Q is a circle and P is convex polygon such that P is bounded by a half circle of Q and all the cuts are line cuts. We give a simple linear time O(log n)-approximation algorithm for this problem where n is the number of vertices of P.

OpenStreetMap for the disaster management in Bangladesh

OpenStreetMap (OSM) is a world-wide campaign for developing open source maps. The prospect of such open source maps is very bright in commercial, educational and political points of views. With the burgeoning growth of mobile phones, the necessity of location based services is increasing day by day. Starting from the 3G mobile applications to cheap SMS-based services, we need maps everywhere. Various applications of digital maps are also seen in different national and international issues. Hence, OSM has been growing at a rapid pace in different parts of the world. However, it is a bit challenging task to develop this sort of voluntary efforts in the developing third world countries, like Bangladesh. In this paper, we discuss the possible fields of disaster responses in Bangladesh where OSM can play a vital role. We also discuss about the problems we face while developing OSM for this region. Finally, we talk about a number of ways which can be instrumental while trying to make free open source maps avoiding all the difficulties.

Privacy in Repair: An Analysis of the Privacy Challenges Surrounding Broken Digital Artifacts in Bangladesh

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 design and development of new interventions or technologies. As a result, the repair of old or broken technologies has been an often neglected topic of research. The goal of our work is to improve the practices surrounding the repair of digital artifacts in developing countries. Specifically, in this paper we examine the privacy challenges associated with the process of repairing digital artifacts, which usually requires that the owner of a broken artifact hand over the technology to a repairer. Findings from our ethnographic work conducted at 10 repair markets in Dhaka, Bangladesh, show a variety of ways in which the privacy of an individuals personal data may be compromised during the repair process. We also examine peoples perceptions around privacy in repair and its connections with broader social and cultural values. Finally, we discuss the challenges and opportunities for future research to strengthen the repair ecosystem in developing countries. Taken together, our findings contribute to the growing discourse around post-use cycles of technology in ICTD and HCI.
