“…Recent studies showed that utilizing tangible objects that the elderly are familiar with and providing a tangible interface with simplified elements may facilitate learning of using these technologies among elderly (Apted et al, 2006;Hung et al, 2016;Garcia-Sanjuan et al, 2017;Wang et al, 2017;Guneysu Ozgur et al, 2018). Furthermore, making the learning of using these devices easier might be crucial, since the lack of familiarity and the steep learning curve of using training devices may reduce the training efficiency among elderly users (Aarhus et al, 2011;Gerling et al, 2011;Guneysu Ozgur et al, 2018). Direct contact via touch interfaces is proposed to provide lower cognitive loads and a more suitable and intuitive alternative, especially for aging users (Garcia-Sanjuan et al, 2017;Guneysu Ozgur et al, 2018).…”
