Beside designing the graphical interface of mobile applications, mobile phones and their built-in sensors enable various possibilities to engage with digital content in a physical, device-based manner that move beyond the screen content. So-called mobile device-based interactions are characterized by device movements and positions as well as user actions in real space. So far, there is only little guidance available for novice designers and developers to ideate and design new solutions for specific individual or collaborative use cases. Hence, the potential for designing mobile-based interactions is seldom fully exploited. To address this issue, we propose a design kit for mobile device-based interaction techniques following a morphological approach. Overall, the kit comprises seven dimensions with several elements that can be easily combined with each other to form an interaction technique by selecting at least one entry of each dimension. The design kit can be used to support designers in exploring novel mobile interaction techniques to specific interaction problems in the ideation phase of the design process but also in the analysis of existing device-based interaction solutions.
