In this paper we explore how screen-based smartphone
interaction can be enriched when designers focus on the
physical interaction issues surrounding the device. These
consist of the hand grips used (Symmetric bimanual,
Asymmetric bimanual with thumb, Single handed,
Asymmetric bimanual with finger), body postures (Sitting at
a table, Standing, Lying down) and the tilting of the
smartphone itself. These physical interactions are well
described in the literature and several research papers
provide empirical metrics describing them. In this paper, we
go one step further by using this data to generate new screenbased
interactions. We achieved this by conducting two
workshops to investigate how smartphone interaction design
can be informed by the physicality of smartphone
interaction. By analysing the outcomes, we provide 14 new
screen interaction examples with additional insights
comparing outcomes for various body postures and grips.
