    This paper presents initial results from the design and evaluation of one-handed squeezing of a mobile phone: the application of force by each individual digit, and combinations of digits, of one hand as a means of interacting with a mobile device. As part of the evaluation we also consider how to alter the size of the interaction space to best suit the number of digits being used. By identifying which digits can accurately apply force both individually and in combination with others, we can then design one-handed, multi-channel input for mobile interaction. The results suggest that not all digits are equally accurate, and that some are more accurate when used in combination with others. Further, increasing the size of the underlying interaction space to suit the number of digits used improves user performance.
