Robot teleoperation has become increasingly crucial for extending human capabilities in inaccessible or hazardous environments and facilitating human–robot collaboration. While significant advancements have been made in teleoperation interfaces, the success of these systems critically depends on how effectively humans can interact with and control robotic systems across diverse manipulation tasks. However, existing research primarily evaluates interfaces within specific tasks or applications, lacking systematic assessment across different manipulation scenarios. This limitation leads to suboptimal interface selection that can compromise task efficiency in critical domains and impede the collection of high-quality demonstrations for robot learning. To address these gaps, we first introduce a novel two-axis Robotic Manipulation Task Taxonomy that systematically categorizes manipulation tasks based on their fundamental control requirements: Motion Type (translation-dominant vs. rotation-dominant) and Engagement Type (rigid vs. non-rigid object interactions). We conducted a comprehensive user study ( \(n=30\) ) evaluating three distinct teleoperation interfaces (Gamepad, 3D Mouse, and Virtual Reality (VR) Controller) based on this taxonomy. Our results indicate that the Gamepad and 3D mouse significantly outperformed the VR Controller in task completion time across all task categories. In contrast, the VR Controller showed higher first-attempt success rates but caused significantly greater cognitive load across all NASA Task Load Index (NASA-TLX) subscales compared to the Gamepad interface, and specifically higher mental demand, physical demand, and effort compared to the 3D mouse. Our results also indicate that although prior familiarity with an interface lowered perceived workload and enhanced perceived performance, it did not translate into improvements in actual task success rates or completion times. These insights provide valuable guidelines for optimizing teleoperation interfaces based on task requirements and highlight the importance of considering both cognitive demands and user experience in interface design.

Imitation Learning, inspired by observational learning theory in cognitive psychology, is a promising approach for teaching robots to perform complex manipulation tasks. However, most imitation learning datasets exhibit biases by focusing on a single interface or modality when capturing human demonstrations. This limitation fails to fully capture the multimodal nature of how humans learn skills through demonstration. To bridge this gap, we introduce the M2RL dataset, a multimodal and multi-interface dataset collected from non-expert users across diverse manipulation tasks from four task categories using three distinct teleoperation interfaces. The M2RL dataset comprises RGB+D data from three camera perspectives (robot’s wrist and two exo-views), ego-view and gaze data from the human teleoperator’s perspective, and the robot’s proprioception data. Our extensive evaluation of state-of-the-art imitation learning algorithms on the M2RL dataset highlights the importance of multimodal and multi-interface data for learning robust policies for the robot. Additionally, the results indicate clear performance improvements when training on data from diverse interfaces and utilizing inputs from multiple camera streams. Our dataset and code are publicly available at: https://github.com/M2RL/m2rl-dataset.

The challenge of designing against child sexual abuse becomes more complicated in conservative societies where talking about sex is tabooed. Our mix-method study, comprised of an online survey, five FGDs, and 20 semi-structured interviews in Bangladesh, investigates the common nature, location, and time of the abuse, post-incident support, and possible combating strategies. Besides revealing important facts, our findings highlight the need of decentering the design from the victims (children and/or guardians) to the community. Hence, building on the theory of transformative justice, we prototyped and evaluated ‘ShishuShurokkha’ – an online tool that involves the whole community by allowing anonymous bystander reporting, visualizing case-maps, connecting with legal, medical, and social support, and raising awareness. The evaluation of ShishuShurokkha shows the promise for such a communal approach toward combating child sexual abuse, and highlights the needs for sincere involvement of the government, NGOs, the legal, educational, and religious services in this.

Financial technology (FinTech) platforms often exclude certain countries from their services due to global political conflicts. As a result, immigrants from these neglected countries struggle with transferring money to and from their homeland through formal mechanisms. Instead, they get involved in informal transnational transactions that, while flexible, are often risky and full of hassles. We looked into this issue through an online survey (n=127) and engaged with multiple stakeholders (n=16), including the Iranian immigrant community in Canada, to co-design an application called ?Kabootar' that matches senders and receivers of money across borders. In this application, a sender-receiver pair is matched with a pertinent pair sending money in the opposite direction. By facilitating two intra-national transactions in local currencies instead of two relatively complicated inter-national transactions, the need for money to cross borders is eliminated while staying within the boundaries of the law. Our user study (n=13) revealed several tensions in users trusting such informal transnational transactions. This work contributes to CSCW, HCI, and social computing's growing scholarship in personalized and collaborative computing technologies by advocating for a novel design approach based on collaboration and informality and extends their scope to the domain of FinTech for politically marginalized communities.

Through Facebook "Group" feature, users often sensitize communionships, join different Facebook groups, and establish imagined communities with known people and strangers. In our interview study with 32 admins and users of Facebook groups, we explored the influential factors of such communionships, the challenges the Facebook group admins face while managing these communities, and how they resolve those. Our findings show that admins set rules for the entry and maintenance of the groups, monitor members' activities, and often limit their actions or mute them during conflicts. Thus, the members and admins of the groups together grow a sensibility of sovereignty within the community on Facebook. While the imagined sovereignty in Facebook groups is empowering, this empowerment may not be perceived and experienced evenly by everyone in such online communities. To explain this, we build on the concept of "Imagined Communities' by Benedict Anderson [16 ] and argue that there is a tension between Facebook admins' perceived sovereignty and other users' empowerment in practice. Our work joins the body of CSCW literature that aims at designing more sustainable and collaborative tools for specific communities on Facebook groups and other similar platforms.

Women in the global south often seek justice to their online harassment through unveiling the harassers and the screenshots of their sent harassment texts and visual contents before the relevant authorities. Nevertheless, such evidence is often challenged for their authenticity. Our survey (n=91) and interview (n=43) with Bangladeshi online gender harassment victims revealed the depth of the problem, and we set design goals to collect evidence from Facebook Messenger with ensured authenticity. Building on the ‘shame-based model’ of gender justice [12], we designed ‘Unmochon’, a tool that captures authentic evidence and shares with victims’ intended group. Our user-study (n=48) revealed that diminishing authenticity problem may still leave the victim and online gender justice entangled with mob-sentiment, hegemonic legal consciousness, and several privacy aspects. Our findings open up a new discussion on how HCI-design should address online gender justice in such a complex social setting.

Inability to read and understand the information on medicine packaging is a problem for many people across the world, especially in the Global South. As a solution to this, many of them reportedly often memorize the names and looks of their medicines. However, they often fail to distinguish between registered and unregistered/duplicate medicines and consume them without realizing, which further deteriorates their health conditions and even may lead to death. They frequently seek help from family members and friends to supervise their medicine intake, however, such helpers might still struggle to distinguish between registered and duplicate medicines if the texts written on the medicine’s packaging seem similar. To address this problem, we designed an android mobile-phone application, ‘Oshudh Poro’ scans medicine packaging, captures images of its unique registry number, matches the number to a database of registered medicines in the country, retrieves the relevant details upon finding the medicine as registered, converts them to Bengali audios and plays the details aloud. Thus, the users know which medicine are they taking, whether it is registered or unregistered and its details. Thus, low-literate users would gain more autonomy in managing their personal medication. We argue that this application would lead wellbeing-HCI to more sustainable design solutions as the application is built on existing skills of users and integrates only the existing features available to the intended users. Thus, our design contributes to wellbeing-HCI, sustainability research, and HCI4D.

Marginalized communities’ access to and use of ICT have long been a concern in HCI4D and social computing. Many works in this domain have pointed out that the challenges to access to ICT often go beyond limited computing resources and skills and frequently include many other socio-cultural factors. In this paper, we report three of the factors that arose while studying rural Bangladeshi women’s access to ICT: stigma, rumor, and superstition. Through an eight-month-long mix-method study with 23 rural women in Jessore, we explored the forms of fear and resistance to use computing devices prevalent among this population, particularly among the women we studied. We report how their stigma, rumors and superstitions often entangled with each other and created a gender-specific resistance to women’s ICT use. This paper further discusses how this resistance was connected to a weak economy and insufficient legal and educational infrastructure in the rural community. We extend the discussion to implications for design, policy, patriarchy, and other social practices to address these human factors in HCI4D and social sustainability scholarship.

Facebook users often join Facebook groups to connect to the people with the same interest regardless of the fact that the other members take the same standing with them. Our study aims to investigate Bangladeshi users' motivation to join and strategies to manage their Facebook groups and identify the relevant challenges. In our ongoing work, we are conducting a survey and interviewing Facebook-group users to understand how Facebook groups are bringing the users of similar interest and agenda together on Facebook and providing the admins with imagined sovereignty. This poster presents some of our crucial findings. This set of findings will be useful in designing better tools for managing Facebook groups for empowering the admins and the users.

Previous Information and Communication Technology and Development (ICTD) research has shown that rural women's access to digital technologies in many Low and Middle Income Countries (LMICs), including Bangladesh, is challenging because of a number of reasons, including Techno-Phobia. With a view to mediating access for rural women, we designed an one-button communication box, and documented rural women's user-experiences with it. Drawing upon our discovery of the set of gender specific and culturally contextual problems, this paper also discusses several design and policy interventions to ensure a better Information and Communication Technology (ICT) access for the rural women in Bangladesh.
