Serious games to cognitively stimulate older adults: A systematic literature review
Palumbo V., Paterno F.
With the increasing number of older adults in today's population, it is important to promote active ageing in order to offer them better life conditions, and enable them to be autonomous as long as possible despite the problems arising from aging. To guarantee active aging, physical, social and mental conditions must be considered. In this research we mainly focus on the cognitive functions implicated in aging. To cope with the cognitive impairments, many proposals have been put forward that exploit digital interactive technologies in interdisciplinary projects. An area that has high potential is the use of serious games supported by some interactive technology because of their potential attractiveness and engagement. We report on a systematic literature review that has been carried out in order to explore and analyse the various proposals in this field and, on the basis of the results, identify the interactive devices that have been considered, the results achieved in terms of cognitive support, and current trends in this area.Source: PETRA '20: The 13th PErvasive Technologies Related to Assistive Environments Conference, pp. 199–208, June, 2020

The transparency of automatic accessibility evaluation tools
Parvin P., Palumbo V., Manca M. Paternò F.
Several web accessibility evaluation tools have been put forward to reduce the burden of identifying accessibility barriers for disabled people. One common issue in using accessibility evaluation tools in practice is that the results provided by different tools are often variable. Such variability may confuse the users who may not understand the reasons behind it, and thus limits the possible adoption of such tools. Hence, there is a need to shed light on the tools' actual functioning, indicate what criteria they should adopt to be transparent and to help users better interpret their results. In this communication paper, we discuss such issues, analyse how they have been addressed by a representative set of tools, and provide useful indications for obtaining user-centred accessibility evaluations.Source: W4A '21: 18th Web for All Conference, Ljubljana, Slovenia, 19-20/04/2021

Micogito: a serious gamebook based on daily life scenarios to cognitively stimulate older adults
Palumbo V., Paterno F.
With the increase in the number of people aged 60 years and older, it becomes essential to promote active ageing. Adequate cognitive training activity can preserve older adults' health conditions, allowing them to live autonomously longer. However, older people often have difficulties with the use of digital technologies and risk being excluded from these. For this reason, this work proposes a solution that introduces older adults to new technologies while maintaining a familiar appearance to them. The solution proposed is Micogito, a web serious game that exploits the book metaphor for cognitive stimulation of older adults. It supports tasks which replicate daily living activities, and has been conceived, and designed to stimulate the most implicated cognitive functions in ageing and particularly in mild cognitive impairment. In its design and implementation, guidelines useful to make web applications accessible and usable for the target users were considered. We also report on a first user test with older adults, to assess the effectiveness of this approach, which provided useful and encouraging feedback, and discuss some lessons learnt.Source: GoodIT 2021 - ACM International Conference on Information Technology for Social Good, pp. 163–168, Rome, Italy, 9-11/09/2021

The transparency of automatic web accessibility evaluation tools: design criteria, state of the art, and user perception
Manca M., Palumbo V., Paternò F., Santoro C.
Several Web accessibility evaluation tools have been put forward to reduce the burden of identifying accessibility barriers for users, especially those with disabilities. One common issue in using accessibility evaluation tools in practice is that the results provided by different tools are sometimes unclear, and often diverging. Such limitations may confuse the users who may not understand the reasons behind them, and thus hamper the possible adoption of such tools. Hence, there is a need for tools that shed light on their actual functioning, and the success criteria and techniques supported. For this purpose, we must identify what criteria should be adopted in order for such tools to be transparent and to help users better interpret their results. In this paper, we discuss such issues, provide design criteria for obtaining user-centred and transparent accessibility evaluation tools, and analyse how they have been addressed by a representative set of open, license-free, accessibility tools. We also report on the results of a survey with 138 users of such tools, aimed at capturing the perceived usefulness of previously identified transparency requirements. Finally, we performed a user study with 18 users working in the Web design or accessibility fields with the goal of receiving more feedback about the transparency of a selected subset of accessibility tools.Source: ACM transactions on accessible computing (2022). doi:10.1145/3556979
