    Guest editorial trustworthiness in social multimedia analytics and delivery
    (IEEE, 2019-03) Su, Z.; Fang, Q.; Wang, H.; Mehrotra, S.; Beğen, Ali Cengiz; Ye, Q.; Cavallaro, A.; Computer Science; BEĞEN, Ali Cengiz
    The papers in this special issue focus on trustworthiness in multimedia communications. Recently, social multimedia content is being delivered to users with a high quality of experience (QoE) with the advance of multimedia technologies and social networks. However, as a huge amount of social users have various demands to exchange and share multimedia content with each other, it becomes a new challenge for the current social multimedia analytics and delivery to deal with the various attacks perpetrated by malicious users or through spam contents. Therefore, the trust and risk management for social multimedia content based on the social tie of users become of prime importance to face the unpredicted threats and subsequent damage. This Special Section aims to provide a premier forum for researchers working on the trust-based social multimedia analytics and delivery. It also provides the opportunity for both academic and industrial researchers to discuss recent results and provide solutions to the above-mentioned challenges.

    The lived experience of child-owned wearables: Comparing children's and parents’ perspectives on activity tracking
    (Association for Computing Machinery, Inc, 2021) İlhan, Işıl Oygür; Su, Z.; Epstein, D. A.; Chen, Y.; Industrial Design; OYGÜR İLHAN, Işil
    Children are increasingly using wearables with physical activity tracking features. Although research has designed and evaluated novel features for supporting parent-child collaboration with these wearables, less is known about how families naturally adopt and use these technologies in their everyday life. We conducted interviews with 17 families who have naturally adopted child-owned wearables to understand how they use wearables individually and collaboratively. Parents are primarily motivated to use child-owned wearables for children's long-term health and wellbeing, whereas children mostly seek out entertainment and feeling accomplished through reaching goals. Children are often unable to interpret or contextualize the measures that wearables record, while parents do not regularly track these measures and focus on deviations from their children's routines. We discuss opportunities for making naturally-occurring family moments educational to positively contribute to children's conceptual understanding of health, such as developing age-appropriate trackable metrics for shared goal-setting and data refection.
