There are many effects that happen like this on your phone currently, and when subtle, greatly improve usability. Take your phone and flip it upside down, and don't allow the device to flip orientation using a lock in software (iOS has the control panel orientation lock switch). You can start to see subtle differences in ease of tapping buttons, targets, etc. The software here is adjusting for how a user actually touches the screen in comparison to where they think they're touching, etc. Here's we're seeing extreme examples, which probably wouldn't work well in practice. But slight integrations could do wonders.
