This article investigates digital and non-digital traces reused beyond the context of creation. A central idea of this article is that no (reused) dataset is perfect. Therefore, data quality assessment becomes essential to determine if a given dataset is "good enough" to be used to fulfill the users' goals. Biases, a possible source of discrimination, have become a relevant data challenge. Consequently, it is appropriate to analyze whether quality assessment indicators provide information on potential biases in the dataset. We use examples representing two opposing sides regarding data access to reflect on the relationship between quality and bias. First, the European Union open data portal fosters the democratization of data and expects users to manipulate the databases directly to perform their analyses. Second, online behavioral advertising systems offer individualized promotional services but do not share the datasets supporting their design. Quality assessment is socially constructed, as there is not a universal definition but a set of quality dimensions, which might change for each professional context. From the users' perspective, trust/credibility stands out as a relevant quality dimension in the two analyzed cases. Results show that quality indicators (whatever they are) provide limited information on potential biases. We suggest that data literacy is most needed among both open data users and clients of behavioral advertising systems. Notably, users must (be able to) understand the limitations of datasets for an optimal and bias-free interpretation of results and decision-making. [ABSTRACT FROM AUTHOR]

This article attends to age stereotypes and ageism in contemporary tech. In academia, little attention has been devoted to this topic. Therefore, we intend to initiate a discussion around ageism in tech by studying perceptions of age in the tech industry. Our study is based on interviews with 18 tech workers around the world of varying age. According to our interviewees, tech workers over 35 are considered old in the tech industry. Older tech workers are expected to become managers, thought to become less interested in new technology, and expected to have more challenges when learning new software. We also look at how tech workers of different age groups experience entrepreneurial values of the company as a playground, staying hungry, and changing the future with technology, and how these values influence their professional careers. We conclude that ageism is reinforced in contemporary tech through several stereotypes related to age.

Digital systems can track every activity. Their logs are the fundamental raw material of intelligent systems in big data approaches. However, big data approaches mainly use predictions and correlations that often fail in the prediction of minorities or invisibilize collectives, causing discriminatory decisions. While this discrimination has been documented regarding, sex, race and sexual orientation, age has received less attention. A critical review of the academic literature confirms that structural ageism also shapes big data approaches. The article identifies some instances in which ageism is in operation either implicitly or explicitly. Concretely, biased samples and biased tools tend to exclude the habits, interests and values of older people from algorithms and studies, which contributes to reinforcing structural ageism.

A major challenge in dentistry is the replacement of teeth lost prematurely due to trauma, caries, or malformations; especially in growing patients. The aim of this study was to assess the accuracy of CAD-CAM surgically guided tooth autotransplantation in cryopreserved cadaver mandibles using guided templates and custom-designed osteotomes. Cryopreserved human cadaver heads were digitized and scanned using an intraoral optical scanner and a large-volume cone beam computed tomography device. First, virtual surgical planning was performed to create a 3D tooth replica, 2 surgical guides, and a custom-made osteotome for each single-rooted tooth autotransplantation procedure/case. Surgical sockets were created in the selected mandibles using guided tooling consisting of an initial guided osteotomy with implant burs and a final guided osteotomy using custom osteotomes. After tooth autotransplantation, second large-volume cone beam computed tomography images of the 5 cadaver mandibles were obtained. The discrepancy in mm within the 3D space (apical and mesiodistal deviations) between the final position of the autotransplanted teeth and their digitally planned 3D initial position was calculated and analyzed statistically (P <.05). All donor teeth were placed without incident within their newly created sockets in the real mandibles. The mean difference between the digitally planned root apex position and the final tooth position was 2.46 ± 1.25 mm. The mesiodistal deviation of the autotransplanted teeth was 1.63 ± 0.96 mm. The autotransplantation of single-rooted teeth with custom-designed and 3D-printed surgical tooling provided promising results. The technique was able to create surgically prepared sockets that could accommodate transplanted teeth in mandibles. [ABSTRACT FROM AUTHOR]

In what ways do mobile communication practices change through later life? To what extent do sociodemographic characteristics, country of residence, and well-being relate to these changing practices? To answer these questions, we used an online, longitudinal study targeting internet users aged 60 and over in six countries (Austria, Canada, Israel, the Netherlands, Spain, and Romania). The focus is on the 3,125 respondents who declared using a mobile phone in every wave (2016, 2018, and 2020). Results show an increasing usage diversification already before the Covid-19 pandemic. A latent class analysis identified three different styles of mobile practices. The most sophisticated relies on almost all the analyzed functions, while the most unsophisticated is limited to voice calls, texting (mainly SMS), and photographs to a lesser extent. Finally, a multinomial analysis provided a picture of the individual characteristics related to the usage styles in the period. The most relevant dimensions were country of residence and age, followed by internet use intensity. The country of residence is relevant to explaining usage because the telecommunications price structure determines the priority given to the mobile phone in (senior) individuals' everyday lives. The article contributes nuanced evidence of the trajectories of digital practices in later life. At the same time, the findings support and better inform country-based policies, services, and products for more effective inclusion of the older population in today's hyper-digitized societies.

Physical manipulatives, such as rods or tiles, are widely used for mathematics learning, as they support embodied cognition, enable the execution of epistemic actions, and foster conceptual metaphors. Counting them, children explore, rearrange, and reinterpret the environment through the haptic channel. Vision generally complements physical actions, which makes using traditional manipulatives limited for children with visual impairments (VIs). Digitally augmenting manipulatives with feedback through alternative modalities might improve them. We specifically discuss conveying number representations to children with VIs using haptic and auditory channels within an environment encouraging exploration and supporting active touch counting strategies while promoting reflection. This paper presents LETSMath, a tangible system for training basic mathematical skills of children with VIs, developed through Design-Based Research with three iterations in which we involved 19 children with VIs and their educators. We discuss how the system may support training skills in the composition of numbers and the impact that the different system features have on slowing down the interaction pace to trigger reflection, on understanding, and on incorporation.

Older adults are increasingly using smartphones. Researchers have identified demographic, attitudinal factors and social outcomes related to inequalities in access, skills, and activities of internet use. While this research has been ongoing for years, studies about the digital inequalities related to the use of smartphones by older adults are still scarce, and they rarely have undertaken sociocultural comparisons of usage. This article builds on an analysis of tracking data of older adults' (pp. 55–79) smartphone use, to explore digital inequalities around traditional axes of inequality and sociocultural factors that shape older adults' smartphone use. It adds a comparative perspective for understanding emerging inequalities related to sociocultural contexts to the existing literature. The results show that differences cannot be explained solely by sociodemographic factors, but also possibly by national policies and culture. Particularly, age, on its own, is not able to explain the differences reported. Older adults engage in a range of different activities on their smartphones, and differences between groups across the traditional axes of inequalities do not mirror exactly the differences found in previous research on internet use. This is important considering the risk of emerging new inequalities and the ongoing revisiting of policies to mitigate them. [ABSTRACT FROM AUTHOR]

The accelerated pace of digital innovations represents a challenge to some individuals, particularly for older people with low digital skills. Several studies focused on information and communication technologies (ICTs) education programs in institutional settings, yet the provision of informal support in the family context is a critical element in the digital literacy of older people. This study examines the familial intergenerational dynamics that facilitate or hinder the digital literacy of grandmothers and carries out a comparison in different cultural contexts. Focus groups were conducted with grandmothers aged 65 and over in Colombia, Italy, Peru, Romania and Spain, followed by thematic analysis. The results show that the grandmothers involved in the study acquire new digital skills through explicit and non-explicit learning dynamics. Grandmothers first resort to their children and grandchildren for explicit requirements, although facing various emotional and attitudinal challenges that hamper this learning. Otherwise, non-explicit learning dynamics emerge in their everyday interaction with offspring and include enactive, immersive, vicarious, and collaborative learning. Thus, intergenerational dynamics are key for grandmothers to keep updated with the continuous flux of innovations. Moreover, the explicit and non-explicit dynamics described should be considered in policies related to digital literacy of older women. [ABSTRACT FROM AUTHOR]

In this paper, we explore ageist depictions of both young and older people as they emerge from discourses addressing 'other people's' digital media usage practices. We carried out eight focus groups (four with teenagers, four with people aged 65 or older) in two southern European cities (Rome and Barcelona). By negotiating the affordances and constraints of (digital) tools and platforms, people develop their own usage norms and strategies, which might – or might not – be intersubjectively shared. Discourses surrounding usage practices and norms tend to refer to what people understand as an appropriate way of using digital platforms: these discourses proved to be powerful triggers for expressing ageist stereotypes; 'the others' were depicted, by both teenage and older participants, as adopting inappropriate usage practices (with regard to content, form, skills and adherence to social norms). These reflections proved to have broader implications on how other age cohorts are perceived: participants tended to take discourses on digital media usage as an opportunity for making generalised judgements about 'the others', which address their manners, as well as their attitude towards communication and social life. Inter-group discrimination processes and ageist stereotypes play a major role in shaping the strong moralistic and patronising judgements expressed by older and younger participants towards 'the other' age cohort.

This article analyzes the idioms of practice and media ideologies of adolescents and older adults regarding mobile digital media usage, and how they are negotiated within and between age cohorts. We formed aged-based focus groups in Rome and Barcelona (four groups of 16- to 19-year-olds and four of 65- to 85-year-olds). The comparison provides new insights on older individuals' communication practices, often overshadowed by the focus on youth. Participants of both age groups explained they do media in their own way, which is perceived as "the right" (or legitimate) way. Strategies and hierarchies differ with age, according to meanings and rankings attributed to media choices in a communicative environment of affordances, or polymedia. The results suggest that differentiated generation-based idioms of practice and media ideologies are in operation in each cohort while, in both cases, refer to adaptative and goal-oriented communications.

Ageism is the most invisible form of discrimination. While there is some awareness of gender, racial, and socioeconomic discrimination on digital platforms, ageism has received less attention. This article analyzes some tools that are frequently embedded on digital platforms from an old-age perspective, in order to increase awareness of the different ways in which ageism works. We will firstly look at how innovation teams, following homophilic patterns, disregard older people. Secondly, we will show how ageism tends to be amplified by the methods often used on digital platforms. And thirdly, we will show how corporate values contradict the usability issues that mainly affect people with a low level of (digital) skills, which is more common among older people. Counterbalancing the abusive power control of the corporations behind digital platforms and compensating for the underrepresentation of groups in less favorable situations could help to tackle such discrimination.

This paper addresses a gap in the Participatory Design (PD) literature, wherein more research on the long-term impact of design projects is warranted. This paper reflects on a 10-year study that intertwined ethnography and 2 PD projects in a community of older learners. Although the goal of our study was to design new digital technologies, the process of designing them presented us with opportunities that gave rise to new non-digital practices, which turned out to be the legacy and most significant outcomes of the PD projects. This result invited us to review the trajectory that led to these outcomes. Our analysis shows that the most important legacy aspect of the projects arose from unexpected forms of user—driven participation that we allowed to co-exist together with those practices more related to the design goals of the PD projects. Drawing upon our results, this paper posits that engagement with PD participants that unfolds over an extended period of time is instrumental in facilitating the development of participation, understanding more deeply long-lasting project outcomes, and legitimising forms of participation that are not directly related to project/design goals.

While wearable technologies, such as smartwatches, are seen as an opportunity to solve some problems often related to older people (65+), e.g. emergencies, physical activity, or isolation, little is known about how older people would domesticate such new technologies. In this study we provided eleven older individuals with smartwatches and tracked their expectations and initial experiences using two interviews. According to our preliminary findings, previous experience with ICTs along with optimistic attitudes toward technology were key to initial domestication of the new technology and overcoming initial problems. Moreover, use was closely related to expectations and personal habits. Participants in this study used smartwatches in similar ways to to those described in previous studies with adults (18-64), including managing notifications and sports' tracking. Additionally, users reported that the smartwatch provided a boost in social status (associated with attributes such as cool, snobbish, young) and created some fashion opportunities and/or concerns.

This paper analyzes how older people, living in Spain, use smartphones and smartphone applications. Using a mixed methods approach, we compare quantitative results obtained by tracking mobile app usage amongst different generational samples with qualitative, focus-group discussions with active smartphone users. A sample of Spanish smartphone users were tracked during one month in the winter of 2014 (238 individuals, aged 20 to 76 years-old). This was followed by three focus group sessions conducted in the spring of 2015, with 24 individuals aged 55 to 81. As we learned, WhatsApp is currently the most popular application used by people of all ages, including older adults. Smartphones increasingly are playing a central role in the life of older participants, although the frequency of app access is negatively correlated with age. On the other hand, as our data indicates, older adults also use a number of different types of apps that are distinct from that of younger users. Older participants access personal information manager apps (calendar, address book and notes) more often than other age groups. And comparatively, older participants use the smartphone less often in stable locations (home, office, relatives' home) with Wifi than somewhere else and with mobile data. As we argue, differences in age seem to reflect the evolution in personal interests and communication patterns that change as we grow older. Our study captures new trends in smartphone usage amongst this cohort. It also indicates how a combination of methods may help to assess the validity of the log and qualitative data. We highlight the relevance of conducting careful generational studies in smartphone use and some of the potentials and limitations of making predictive studies of ICT use as we change throughout the life course. Finally, we assert the value of the inclusion of older representatives within research, which ultimately may influence public decisions and the design of new technologies. [ABSTRACT FROM AUTHOR]

While older people tend to be regarded as actual, or potential, players of digital games within literature on game studies, human–computer interaction, and gerontechnology, they are also often considered nonavid users of digital technologies. This contradiction prompted us to conduct a literature review, which revealed (a) insufficient involvement of older people within the design of games targeted toward this group and (b) insufficient understanding of their everyday digital gameplay. In this article, we present the conceptualization, design, and evaluation of digital games that active older people found to be sufficiently appealing, playable, and meaningful. A 6-month ethnography of the play experiences of 170 older people helped us to conceptualize these games, which were codesigned through playful everyday activities. To facilitate the development of these games, we designed and evaluated an online game creation platform, which enabled 99 older people with different cultural backgrounds to create, play, and contribute to games.

This paper discusses the evocative power and play value of the Wearable Sounds Kit (WSK), a movement-to-sound interaction accessory. Whilst movement-to-sound interaction is attracting growing research attention in HCI, very little of it has been conducted in the context of free-play with children. This paper presents a participatory design study of the WSK with 20 school-aged children (7-12 years old) in a free-play scenario, and an evaluation of the WSK in a playground at Ars Electronica Festival with over 70 school-aged children. The evaluation addressed three research questions: can school-aged children incorporate the WSK into their free-play? What free-play patterns are encouraged by the WSK? Which design features of the WSK influence the free-play experience? By conducting qualitative and quantitative data gathering methods and analyses, which include first-hand observations and video-coding, this paper shows that school-aged children can effectively incorporate the WSK into their free-play, and that the accessory encourages different types of free-play. The results also show differences in the free-play mediated by the accessory depending on the age group and sex of the player, and these differences reinforce the play value of the WSK. Some implications for designing technologically-oriented playful toys are also discussed. [ABSTRACT FROM AUTHOR]

Involving older people through co-design has become increasingly attractive as an approach to develop technologies for them. However, less attention has been paid to the internal dynamics and localized socio-material arrangements that enact this method in practice. In this paper, we show how the outcomes that can be achieved with user involvement often pertain to learning, but their content can differ significantly based on how the approach is implemented in practice. Combining explorative, qualitative findings from co-design conducted in four countries (Canada, the Netherlands, Spain, and Sweden), we illustrate how different types of learning occurred as design workshops engaged the experiences and skills of older people in different ways. Our findings make visible how learning can be a core outcome of co-design activities with older adults, while raising awareness of the role of the power relations and socio-material arrangements that structure these design practices in particular ways. To benefit from the full wealth of insights that can be learned by involving older people, deeper knowledge is needed of the implicit features of design, the materials, meanings, and power aspects involved.
