Integrated Web Accessibility Guidelines for Users on the Autism Spectrum - from Specification to Implementation

This research presented a compendium of web interface design guidelines and their implementation on a transport-planning website based on the needs and preferences of users on the autism spectrum. Results highlighted the importance of having simple navigation and meaningful headings, icons, labels and text to facilitate understanding and readability; these findings offer guidelines for the design of web user interfaces to continue improving the web experience of autistic users, and therefore of the whole community

Affective Medicine: a review of Affective Computing efforts in Medical Informatics

Background: Affective computing (AC) is concerned with emotional interactions performed with and through computers. It is defined as “computing that relates to, arises from, or deliberately influences emotions”. AC enables investigation and understanding of the relation between human emotions and health as well as application of assistive and useful technologies in the medical domain. Objectives: 1) To review the general state of the art in AC and its applications in medicine, and 2) to establish synergies between the research communities of AC and medical informatics. Methods: Aspects related to the human affective state as a determinant of the human health are discussed, coupled with an illustration of significant AC research and related literature output. Moreover, affective communication channels are described and their range of application fields is explored through illustrative examples. Results: The presented conferences, European research projects and research publications illustrate the recent increase of interest in the AC area by the medical community. Tele-home healthcare, AmI, ubiquitous monitoring, e-learning and virtual communities with emotionally expressive characters for elderly or impaired people are few areas where the potential of AC has been realized and applications have emerged. Conclusions: A number of gaps can potentially be overcome through the synergy of AC and medical informatics. The application of AC technologies parallels the advancement of the existing state of the art and the introduction of new methods. The amount of work and projects reviewed in this paper witness an ambitious and optimistic synergetic future of the affective medicine field

Overcoming barriers and increasing independence: service robots for elderly and disabled people

This paper discusses the potential for service robots to overcome barriers and increase independence of elderly and disabled people. It includes a brief overview of the existing uses of service robots by disabled and elderly people and advances in technology which will make new uses possible and provides suggestions for some of these new applications. The paper also considers the design and other conditions to be met for user acceptance. It also discusses the complementarity of assistive service robots and personal assistance and considers the types of applications and users for which service robots are and are not suitable

WiBAF into a CMS: Personalization in learning environments made easy

Adaptivity has proven successful in reducing navigation and comprehension problems in hypermedia documents. Authoring of adaptive hypermedia documents and especially of the adaptivity in these documents has been problematic or at least labour intensive throughout AH history. This paper shows how the integration of a CMS with an adaptive framework greatly simplifies the inclusion of personalization in existing educational applications. It does this within the context of European project Autism&Uni that uses adaptive hypermedia to offer information for students transitioning from high school to university, especially to cater for students on the autism spectrum as well as for non-autistic students. The use of our Within Browser adaptation framework (WiBAF) reduces privacy concerns because the user model is stored on the end-user's machine, and eliminates performance issues that currently prevent the adoption of adaptivity in MOOC platforms by having the adaptation performed on the end-user's machine as well (within the browser). Authoring of adaptive applications within the educational domain with the system proposed was tried out with first year students from the Design-Based Learning Hypermedia course at the Eindhoven University of Technology (TU/e) to gather feedback on the problems they faced with the platform

Can Computer-Assisted Training of Prerequisite Motor Skills Help Enable Communication in People with Autism?

Our and others' research indicates that in fully a third of people with autism who lack communicative speech, the communication deficit may actually be a deficit in motor skills necessary to move the mouth and the vocal tract. These individuals have difficulties in fine, gross and especially oral motor skills, and a disparity between impaired expressive language and relatively intact receptive language: that is to say, they can listen but not speak. Because involvement in research and receipt of the fullest educational, occupational and other services demands ability to interact verbally and to control one's movements and actions, these people get the short end of the stick when it comes to scientific enquiry and pedagogic and therapeutic practice. Point OutWords, tablet-based software designed in collaboration with autistic clients and their communication therapists, exploits the autistic fascination with parts and details to motivate attention to learning manual motor and oral motor skills essential for communication. Along the way, autistic clients practise pointing and dragging at objects, then pointing at sequences of letters on a keyboard, and even speaking the syllables represented by these letters. Whereas many teaching and learning strategies adapted from methods for non-autistic people end up working against autistic cognition by asking people with autism to do what they cannot easily do, Point OutWords works with autistic cognition, by beginning from the autistic skill at manipulating parts and details. Users and their parents or guardians can opt into collection of data on motor interactions with Point OutWords; these internal measures of motor skills development are complemented by external, standardised tests of motor, oral motor and communicative development. These quantitative measures are collected alongside reports on Point OutWords's acceptability to users, and users' fidelity to a recommended treatment regime, so as to evaluate feasibility of a larger randomised controlled trial

Distributed Cognition as a framework for accessible design

In order to navigate the world, humans have historically made tools that allowed them to exploit their environment in ways beyond their natural physical and mental capacities. This continues to be true in the information age. Being able to use digital tools in this age affords the individual agency to influence and participate in the world and so it is critical that this capacity is equally available to all people. Current standards of accessibility attempt to create accommodations for overlooked populations in the form of guidelines, but these rely on a flawed approach to accessibility that is surface-level and lacks understanding of the populations to which it caters. However, distributed cognition offers an approach through which we can understand users through their interaction strategies with technology and through which we can understand technology as an extension of the mind. This paper explores the short-comings of current approaches to accessible design, how distributed cognition has been used to describe human-computer interactions and how this can be extended to understand accessible design. A case study of how a distributed cognition approach may transform accessible design for individuals with Autism Spectrum Condition is developed and discussed

A tablet computer-assisted motor and language skills training programme to promote communication development in children with autism: development and pilot study

Autism is a heterogenous condition, encompassing many different subtypes and presentations. Of those people with autism who lack communicative speech, some are more skilled at receptive language than their expressive difficulty might suggest. This disparity between what can be spoken and what can be understood correlates with motor and especially oral motor abilities, and thus may be a consequence of limits to oral motor skill. Point OutWords, tablet-based software targeted for this subgroup, builds on autistic perceptual and cognitive strengths to develop manual motor and oral motor skills prerequisite to communication by pointing or speaking. Although typical implementations of user-centred design rely on communicative speech, Point OutWords users were involved as co-creators both directly via their own nonverbal behavioural choices and indirectly via their communication therapists’ reports; resulting features include vectorised, high-contrast graphics, exogenous cues to help capture and maintain attention, customisable reinforcement prompts, and accommodation of open-loop visuomotor control

Accessible and usable websites and mobile applications for people with autism spectrum disorders: A comparative study

Accessibility, usability and inclusion represent desirable challenges of current research in the field of universal design: in some cases, these features require adaptive behaviours and specialised customisations, while, in general, it is possible to identify common and hareable guidelines. We focus our attention on hildren with autism spectrum disorders. Many studies show the positive impact of using computer technologies for supporting the lives of these users. Despite that, just a restricted part of the current websites and apps is accessible and usable for people with ASD. In this paper, we present general and shared guidelines and best practices for accessibility and usability for all; and we propose specialised guidelines for designers and developers of websites and mobile applications for users with ASD. We then present a review of many of the existing websites and applications, in order to check which comply with all, or parts of these guidelines
