We propose spatial correspondence targeting to support interaction between devices in multi-device environments when network connectivity fails. In spatial correspondence targeting, for a given target on surface A, an end-user envisions the relative position of that target on surface B and interacts on surface B without any visual depiction of the target on surface B. The targeting task relies on human spatial visualization ability, i.e. the ability to relate the spatial position of objects on one display to their scale-invariant position on another display. We provide experimental evidence that demonstrates that users may be able to target up to 25 discrete targets using a smartphone screen even in the absence of a depiction of the target on the smartphone screen. We argue that the accuracy of spatial correspondence targeting is sufficient for the technique to have many practical applications.
