A movement compensation system is described herein that compensates a user interface and received touch input based on detected external motion affecting a mobile computing device. The system uses the integration of accelerometer data to either offset screen rendering or adjust screen size to improve readability. The system may also improve touch target selection by offsetting received touch coordinates to compensate for device shifting. Offsets can be applied to either the screen rendering offset or can be applied to the touch coordinate input. The system may increase font size or the size of other user interface elements in response to detecting external motion. The system may also receive tuning parameters to account for device mass, dampening filters on accelerometer integrations, latency effects, and user responsiveness to motion effects. Thus, the system allows users to continue to use devices under high motion environmental conditions.
