Tangible user interfaces (TUIs) may allow users to have more direct interaction with systems when compared to traditional graphical user interfaces (GUIs). However, the full range of applications where TUIs can be utilized in practice is unclear. To resolve this problem, the benefits of TUIs must be analyzed and matched to an application domain where they hold advantages over more traditional systems. Since TUIs require users to use their hands in order to interact with the system, there is the possibility for these systems to leverage motor leaning to perform specific tasks.
This work explored how motor learning can be used to create a tangible password system. A novel tangible password system was created and a small study conducted in order to identify future research objectives. Results show that users were successful in using the system to input their password and were able to recall their password after being removed from the system for a brief period of time.
