Information and communication technology (ICT) tools can have a catalytic effect in advancing both educational access and learning outcomes for children with disabilities. Despite tremendous potential, a gap exists between technology advancements and their large-scale application in educating children with disabilities in low- and middle-income countries. This landscape review of ICTs for disability-inclusive education by the Inclusive Education Initiative seeks to understand the current status and trends in the practice of educational technology (EdTech) and the use of ICT in improving the educational participation and outcomes of children with disabilities. The review explores what factors enable or restrict this improvement within the wider EdTech ecosystem.

STEP-UP: Enabling Low-Cost IMU Sensors to Predict the Type of Dementia During Everyday Stair Climbing

Catherine Holloway, William Bhot, Keir X. X. Yong, Ian McCarthy, Tatsuto Suzuki, Amelia Carton, Biao Yang, Robin Serougne, Derrick Boampong, Nick Tyler, Sebastian J. Crutch, Nadia Berthouze and Youngjun Cho

Posterior Cortical Atrophy is a rare but significant form of dementia which affects people's visual ability before their memory. This is often misdiagnosed as an eyesight rather than brain sight problem. This paper aims to address the frequent, initial misdiagnosis of this disease as a vision problem through the use of an intelligent, cost-effective, wearable system, alongside diagnosis of the more typical Alzheimer's Disease.

STEP-UP: Enabling Low-Cost IMU Sensors to Predict the Type of Dementia During Everyday Stair Climbing

Posterior Cortical Atrophy is a rare but significant form of dementia which affects people's visual ability before their memory. This is often misdiagnosed as an eyesight rather than brain sight problem. This paper aims to address the frequent, initial misdiagnosis of this disease as a vision problem through the use of an intelligent, cost-effective, wearable system, alongside diagnosis of the more typical Alzheimer's Disease. We propose low-level features constructed from the IMU data gathered from 35 participants, while they performed a stair climbing and descending task in a real-world simulated environment. We demonstrate that with these features the machine learning models predict dementia with 87.02% accuracy. Furthermore, we investigate how system parameters, such as number of sensors, affect the prediction accuracy. This lays the groundwork for a simple clinical test to enable detection of dementia which can be carried out in the wild.

Transforming a Monolithic Sheet of Nitinol into a Passive Reconfigurable Tactile Pixel Array Display at Braille Resolution

Tigmanshu Bhatnagar, Nicolai Marquardt, Mark Miodownik, Catherine Holloway

Shape changing materials create a unique opportunity to design reconfigurable tactile display actuators. In this paper, we present a method that transforms a single thin monolithic sheet of Nitinol into a passive reconfigurable tactile pixel array at Braille resolution. We have designed a 27x27 tactile pixel array in which each pixel can be selectively actuated with an external source of heat. The pixels rise 0.4mm vertically with a peak blocked force of 0.28kg and have an average blocked force of 0.23kg at room temperature. After cooling, the pixels can be mechanically reconfigured back to their flat state for repeatable actuation. We demonstrate this actuator’s interactive capabilities through a novel erasable tactile drawing interface.

Disability Design and Innovation in Low Resource Settings: Addressing Inequality Through HCI.

Giulia Barbareschi, Dafne Zuleima Morgado-Ramirez, Catherine Holloway, Swami Manohar Swaminathan, Aditya Vashistha, and Edward Cutrell.

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.

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.

A right to the frivolous? Renegotiating a wellbeing agenda for AT research

Giulia Barbareschi & Tom Shakespeare

Assistive products (APs) are broadly defined as “any product (including devices, equipment, instruments, and software), either specially designed and produced or generally available, whose primary purpose is to maintain or improve an individual’s functioning and independence and thereby promote their wellbeing” (Khasnabis et al., 2015). Although the concept of wellbeing is extremely slippery and researchers have yet to agree on a single definition for it, as individuals we instinctively develop mental models about what does, and does not, promote our happiness and wellbeing. Considerations about values, wellbeing and happiness are extremely personal and are shaped by a variety of factors ranging from our age and socio-cultural background to our life experiences (Schwartz & Bardi, 2001).

Abstract

A right to the frivolous? Renegotiating a wellbeing agenda for AT research

Assistive products (APs) are broadly defined as “any product (including devices, equipment, instruments, and software), either specially designed and produced or generally available, whose primary purpose is to maintain or improve an individual’s functioning and independence and thereby promote their wellbeing” (Khasnabis et al., 2015). Although the concept of wellbeing is extremely slippery and researchers have yet to agree on a single definition for it, as individuals we instinctively develop mental models about what does, and does not, promote our happiness and wellbeing. Considerations about values, wellbeing and happiness are extremely personal and are shaped by a variety of factors ranging from our age and socio-cultural background to our life experiences (Schwartz & Bardi, 2001).

However, when it comes to assistive technology (AT) research, our focus seems to be primarily geared toward values and activities in the domains of education, employment, transport or health, often framed according to an outcome driven perspective that is heavily influenced by what is seen as useful (often what is measurable), vs what is frivolous (less tangible social or emotional aspects).

This disparity parallels the priorities of the disability rights movement and disability studies research that have helped to shape the research agenda around disability and AT. Often influenced by labor movement politics, or feminism, there appears to have been more concern with public and practical aspects of social life as opposed to the more private and sensitive ones (Shakespeare, 2014). The focus on the public utilitarian function of AT becomes even more evident when we consider AT research carried out in the Global South. In this context the success of an intervention is usually assessed using measures of outcome and impact which can be somehow linked to economic improvement (Alkire, 2016).

In this editorial, we are not suggesting that enabling people with disabilities to gain a good education, obtain a fulfilling job or be able to vote are not important goals for the APs we develop and research. But are those the only worthwhile goals? Should we not also enquire whether existing and future APs could help people with disabilities to develop meaningful friendships, enjoy fulfilling sex lives with their partners of choice, cook sociable dinners, or engage in their favorite hobbies? Although sporadic publications focus on the role of APs in the context of personal relationships, sexuality, or fun and play for people with disabilities do exist, these are rare, and often framed around utilitarian goals. For example, research around AT and play is largely focused on children and often examined in connection to learning outcomes. Similarly, sex and sexuality are often explored solely in connection to dysfunction, abuse or sexual health (Shakespeare & Richardson, 2018).

These unbalanced narratives show how the AT research agenda is dictated by a set of universal priorities that are largely focused on global measurable goals that do not necessarily match the everyday values of people with disabilities. We invite researchers and practitioners to consider ways to find a better balance between public and private aspects of life, and between utilitarian and emotional values. Both approaches have a significant impact on the lives of people with disabilities.

Ultimately, as AT researchers we need to actively engage with people with disabilities to uncover their priorities, understand what different people with disabilities most value in life, and identify how current and future APs might help to make a positive impact on wellbeing. Aspects of life such as friendship, socialization, sexuality, love and play might indeed be more frivolous than practical ones such as education, health, employment and civil rights, but they are inherent to our shared humanity and fundamental to our happiness.

What difference does tech make? Conceptualizations of Disability and Assistive Technology among Kenyan Youth: Conceptualizations of Disability and AT

In this paper, we examine how young Kenyans without disabilities view people with disabilities and AT users. Findings show that while the portrayal of disability is often shaped by negative emotion, participants felt that many of the barriers affecting people with disabilities were created by society. Perceptions of AT differed –devices were not only seen as a mark of disability but also as a sign of access to resources. Therefore, what we see is an emergent picture where social barriers can be reinforced by poverty, and where poverty reinforces social barriers faced by people with disabilities. We conclude that access to appropriate technology alongside societal interventions tackling incorrect beliefs about disability can help to overcome the stigma faced by people with disabilities.

Abstract

What difference does tech make? Conceptualizations of Disability and Assistive Technology among Kenyan Youth: Conceptualizations of Disability and AT

Most research which investigates stigma towards with people with disabilities and the use of Assistive Technology (AT) are based in the Global North and focus on the experiences of people with disabilities and the consequences that stigma has on choices surrounding AT. However, stigma is a societal construct rooted in the attitude and beliefs that people without disabilities hold on disability and AT. Furthermore, the portrayal of people with disabilities and AT is dependent on the social context. In this paper, we examine how young Kenyans without disabilities view people with disabilities and AT users. Findings show that while the portrayal of disability is often shaped by negative emotion, participants felt that many of the barriers affecting people with disabilities were created by society. Perceptions of AT differed –devices were not only seen as a mark of disability but also as a sign of access to resources. Therefore, what we see is an emergent picture where social barriers can be reinforced by poverty, and where poverty reinforces social barriers faced by people with disabilities. We conclude that access to appropriate technology alongside societal interventions tackling incorrect beliefs about disability can help to overcome the stigma faced by people with disabilities.
