The Human Side of Computing


Historically, computing has been envisioned as a way to enhance what we, as humans, are able to do. Nowhere is such a computing goal more evident than in the field of accessibility where we seek to create devices and software to address needs of people who have disabilities. In creating accessible technology and novel accessibility tools, research has not only facilitated digital interactions and quality of life needs for many, but also has served to advance the field of computing more generally. The needs of users can and should inform the agenda for emerging research in areas such as augmented memory, physical interactions, and human communication.


Vicki Hanson is a Distinguished Professor at RIT within the HCI and Accessibility research groups. She also is Chair of Inclusive Technologies at the University of Dundee where she leads multiple efforts related to inclusion of older adults and individuals with disabilities. From 1986 – 2009 she was a Research Staff Member and Manager at IBM’s T. J. Watson Research Center in New York, founding the Accessibility Research Group in 2000.
Her work on accessibility stemmed from language and educational access questions and over the years has grown to include development efforts to support the aging population and people with diverse abilities. For these efforts she has been recognized both by industry and academic honors, including an IBM Corporate Award, the Wolfson Research Merit Award from the Royal Society, the Social Impact Award from ACM SIGCHI and the ACM SIGCACCESS Award for Contributions to Computing and Accessibility.
She currently serves as the ACM Vice President and as a member of the ACM-W Europe Executive Committee. She is Past Chair of SIGACCESS and was Co-Founder and Editor-in-Chief of ACM Transitions on Accessible Computing. She serves on Fellows Committees for ACM and the Royal Society of Edinburgh and has been active in conference organizing and program committees for ASSETS, CHI, and several other ACM conferences.
She is a Fellow of the ACM, a Chartered Fellow of the British Computer Society, and a Fellow of the Royal Society of Edinburgh.

Changing Services in a Changing World


In our days ICT technologies change very fast and are quickly taken up by the market. Digital natives, digital immigrants and nonliner describe digital socialization paths and lead to different user groups. It is very obvious that the ways of information and communication through technology have changed substantially with an immense impact on society. Private communications and interactions are run in social networks, e-commerce and e-government amend and replace traditional means. Services are available on the move and embedded in ambient intelligent environments through smartphones and data transfer options. At the very same time our societies are ageing, with less children, less people in gainful employment and a growing number of older people. Taking these two important trends together the question arises how to make best use of the available human and technological resources.
Most people agree that best use of human resources means to engage people in human oriented tasks with low physical burden, little negative stress and minimal risk for accidents, illness and death. Further, activities shall be connected to social interaction, support of wellbeing and health and a meaningful life. Best use of technological resources can support these objectives in various ways, by easing, simplifying, assisting tasks and jobs. They themselves shall not create damage or disadvantage to people. Everyone shall be able to use technological services or decide to continue in acquainted ways.
One problem is the exclusion of people from benefitting from new technological services. Main aspects here are required knowledge and skills, education, physical and cognitive abilities, affordability and data security issues. Availability of devices, infrastructures and services particularly in rural areas comprises another thread. Universal design and design for all provide concepts for overcoming these issues. ICT contains a huge potential for the implementation of such concepts.
Relating to the ageing population with changing physical, sensorial and cognitive abilities technological support also offers a lot. Traditionally, we have separated such support technologies as technical aids in a medical system often in a regulated health care market. Suitable and good functionalities have been offered to people, but often at high cost, with a need to accept to be old or having a disability and often with stigmatizing patterns. Now, carrying a mobile device, with computing power, with data connection to the cloud, connectivity to other devices and various sensor options, we have everyday technology at hand which can take over many of the traditional functionality of technical aids.
In order to unlock the inherent potential, we need to rethink the ways of interaction of the players, the market organization and support frameworks. Several initiatives have been started towards this and in this talk examples will be presented. Aspects of ongoing developments and discussions are taken up and reflected.

Advanced signal processing perspectives towards innovative human assistive technology


The proposed lecture will present advanced achievements in the field of affective computing towards more enhanced human-computer-interaction interfaces, presenting advanced signal processing techniques and implementations applied to Electroencephalogram (EEG) recordings. In particular, the way emotions are ‘reflected’ in our brain signals, the way actions (both in explicit and implicit way, e.g., gestures in music) are combined with internal representations in our brain (involving mirror neuron system activation), and how our brain decides if it likes or not the perceived music will be presented and discussed. Moreover, potential implementations of the findings in the field of human assistive technology will be shown, including innovative ways of pain management and Alzheimer’s community support.

The Accessible, the Mobile and the Web


Being accessible means to provide a good experience to users, independently of their capabilities at the moment of use. Even in its most restricted definition, this implies that an accessible interactive system should address the needs of all. It encloses thus a universal implication. Mobility, when applied to these systems, means that a user should be able to use it wherever he stands and whatever he is doing. Implicitly, and the reality reinforces it, it encloses a notion of omnipresence, a different but yet related universal stance. It is not strange, therefore, that situational impairments often emerging from mobility should, at least for some, be considered under the accessibility umbrella. Finally, what could be more universal than the web? As the previous concepts it infolds, here by reality, intent or misconception, the perceptions of omnipresence, omniscience and egalitarianism.
This unequivocal similitudes imply for sure interrelated preoccupations for those developing interactive systems. As a consequence, systems, applications, frameworks and techniques, share related ideas and solutions. Moreover, at the fusion of these concerns, on mobile accessibility, mobile web, web accessibility, and of course mobile web accessibility, lies an extraordinary challenge to the designers that could actual provide universal solutions. Synergies, merged solutions, and holistic views will be contemplated hopefully raising awareness to a broader perspective of accessibility.
