    Fingerprint Quality: a Lifetime Story
    (BIOSIG 2018 - Proceedings of the 17th International Conference of the Biometrics Special Interest Group, 2018) Galbally, Javier; Haraksim, Rudolf; Beslay, Laurent
    Currently, it is a largely accepted fact that biometric sample quality is the most determinant factor to achieve high recognition accuracy in biometric systems. However, even in extensively researched characteristics such as fingerprints, there is still a lack of evidence on how quality evolves throughout the life of an individual. For instance, how does the quality of children fingerprints compare to that of adults or elders? Do these changes imply any age limits for the use of fingerprints with current technology? The present paper addresses this key problem based on a database of over 400K fingerprints coming from more than 250K different fingers. The database was acquired under real operational conditions and contains fingerprints from subjects aged between 0 and 98 years. Such a unique set of data has allowed us to analyse for the first time how fingerprint quality changes through life.

    Tangible Coding Board: A Steping Stone to Computing and Fabrication for Children
    (Mensch und Computer 2017 - Workshopband, 2017) Root, Erika; Ananthanarayan, Swamy; Heuten, Wilko; Boll, Susanne
    Computational thinking is increasingly important in today's world and teaching children this skill is important for their future. Teaching children programming is one way to develop computational thinking skills. HCI researchers have already explored different construction kits for teaching programming to different age groups. But, there is a trade-off between functionality and easy of use for newcomers. In this paper, we present the design of a Tangible Coding Board for children between the ages of 10 to 12 years which could help children to get into fabrication and minimal programming. With our toolkit, children can potentially program sensors and actuators in a tangible way to make their own interactive designs and fabricate personally meaningful artifacts.
