We present an investigation into how hand usage is affected by different body postures (Sitting at a table, Lying down and Standing) when interacting with smartphones. We theorize a list of factors (smartphone support, body support and muscle usage) and explore their influence the tilt and rotation of the smartphone. From this we draw a list of hypotheses that we investigate in a quantitative study. We varied the body postures and grips (Symmetric bimanual, Asymmetric bimanual finger,

Our results showed that the body posture Lying down had the most movement, followed by Sitting at a table and finally Standing. We additionally generate reports of motions performed using different grips. Our work extends previous research conducted with multiple grips in a sitting position by including other body postures, it is anticipated that UI designers will use our results to inform the development of mobile user interfaces.
