Artificial Intelligence (AI) in Education has been said to have the potential for building more personalised curricula, as well as democratising education worldwide and creating a Renaissance of new ways of teaching and learning. Millions of students are already starting to benefit from the use of these technologies, but millions more around the world are not. If this trend continues, the first delivery of AI in Education could be greater educational inequality, along with a global misallocation of educational resources motivated by the current technological determinism narrative. In this paper, we focus on speculating and posing questions around the future of AI in Education, with the aim of starting the pressing conversation that would set the right foundations for the new generation of education that is permeated by technology. This paper starts by synthesising how AI might change how we learn and teach, focusing specifically on the case of personalised learning companions, and then move to discuss some socio-technical features that will be crucial for avoiding the perils of these AI systems worldwide (and perhaps ensuring their success). This paper also discusses the potential of using AI together with free, participatory and democratic resources, such as Wikipedia, Open Educational Resources and open-source tools. We also emphasise the need for collectively designing human-centered, transparent, interactive and collaborative AI-based algorithms that empower and give complete agency to stakeholders, as well as support new emerging pedagogies. Finally, we ask what would it take for this educational revolution to provide egalitarian and empowering access to education, beyond any political, cultural, language, geographical and learning ability barriers.

Extracting useful information from the user history to clearly understand informational needs is a crucial feature of a proactive information retrieval system. Regarding understanding information and relevance, Wikipedia can provide the background knowledge that an intelligent system needs. This work explores how exploiting the context of a query using Wikipedia concepts can improve proactive information retrieval on noisy text. We formulate two models that use entity linking to associate Wikipedia topics with the relevance model. Our experiments around a podcast segment retrieval task demonstrate that there is a clear signal of relevance in Wikipedia concepts while a ranking model can improve precision by incorporating them. We also find Wikifying the background context of a query can help disambiguate the meaning of the query, further helping proactive information retrieval.

Disability interactions (DIX) is a new approach to combining cross-disciplinary methods and theories from Human Computer Interaction (HCI), disability studies, assistive technology, and social development to co-create new technologies, experiences, and ways of working with disabled people. DIX focuses on the interactions people have with their technologies and the interactions which result because of technology use. A central theme of the approach is to tackle complex issues where disability problems are part of a system that does not have a simple solution. Therefore, DIX pushes researchers and practitioners to take a challenge-based approach, which enables both applied and basic research to happen alongside one another. DIX complements other frameworks and approaches that have been developed within HCI research and beyond. Traditional accessibility approaches are likely to focus on specific aspects of technology design and use without considering how features of large-scale assistive technology systems might influence the experiences of people with disabilities. DIX aims to embrace complexity from the start, to better translate the work of accessibility and assistive technology research into the real world. DIX also has a stronger focus on user-centered and participatory approaches across the whole value chain of technology, ensuring we design with the full system of technology in mind (from conceptualization and development to large-scale distribution and access). DIX also helps to acknowledge that solutions and approaches are often non-binary and that technologies and interactions that deliver value to disabled people in one situation can become a hindrance in a different context. Therefore, it offers a more nuanced guide to designing within the disability space, which expands the more traditional problem-solving approaches to designing for accessibility. This book explores why such a novel approach is needed and gives case studies of applications highlighting how different areas of focus—from education to health to work to global development—can benefit from applying a DIX perspective. We conclude with some lessons learned and a look ahead to the next 60 years of DIX.

Globally persons with disabilities have lower employment rates compared to the general population due to systemic barriers particularly in the formal sector. In developing countries, 80 percent to 90 percent of people with disabilities of working age are unemployed. There has been limited research in low-income and middle-income countries focused on the barriers to access and retain formal employment for persons with disabilities. The aim of this paper, based on desk research, is to analyse the barriers to access and retain formal employment of persons with disabilities which are framed in three categories according to where the barriers primarily manifest: 1. In the workplace among employers and co-workers without disabilities, 2. Among persons with disabilities seeking or engaged in formal employment and 3. In the wider social, physical and policy environment. Although the study mainly focuses on Kenya and Bangladesh other countries’ literature on access to and retention of employment of persons with disabilities were reviewed where relevant. In the current context where the global pandemic is breaking barriers to remote working one part of the solution will be to empower persons with disabilities with appropriate access to Information and Communication Technology, assistive devices and services, digital skills, creating more accessible and inclusive digital platforms for persons with disabilities which also hold the potential to improve working conditions and productivity for the whole workforce as well as enhancing resilience to potential future shocks.

The emerging possibilities of multisensory interactions provide an exciting space for disability and open up opportunities to explore new experiences for perceiving one's own body, it's interactions with the environment and also to explore the environment itself. In addition, dynamic aspects of living with disability, life transitions, including ageing, psychological distress, long-term conditions such as chronic pain and new conditions such as long-COVID further affect people's abilities. Interactions with this diversity of embodiments can be enriched, empowered and augmented through using multisensory and cross-sensory modalities to create more inclusive technologies and experiences. To explore this, in this workshop we will explore three related sub-domains: immersive multi-sensory experiences, embodied experiences, and disability interactions and design. The aim is to better understand how we can re-think the senses in technology design for disability interactions and the dynamic self, constructed through continuously changing sensing capabilities either because of changing ability or because of the empowering technology. This workshop will: (i) bring together HCI researchers from different areas, (ii) discuss tools, frameworks and methods, and (iii) form a multidisciplinary community to build synergies for further collaboration.

Approximately 15% of the world's population has a disability and 80% live in low resource-settings, often in situations of severe social isolation. Technology is often inaccessible or inappropriately designed, hence unable to fully respond to the needs of people with disabilities living in low resource settings. Also lack of awareness of technology contributes to limited access. This workshop will be a call to arms for researchers in HCI to engage with people with disabilities in low resourced settings to understand their needs and design technology that is both accessible and culturally appropriate. We will achieve this through sharing of research experiences, and exploration of challenges encountered when planning HCI4D studies featuring participants with disabilities. Thanks to the contributions of all attendees, we will build a roadmap to support researchers aiming to leverage post-colonial and participatory approaches for the development of accessible and empowering technology with truly global ambitions.
