For improving a future UI design, a set of data is analyzed. A data in a first subset of the set includes (i) a description of a UI layout including a description of a UI element in a first area of a touch-sensitive device, the first area having a below a level of sensitivity, the data, and (ii) a second area of the touch-sensitive device having a second sensitivity at least equal to the level of sensitivity. A characteristic of the UI element is extracted. A threshold number of data in the first subset include some UI element with the characteristic. For a first area in each data in the subset, the characteristic is determined to cause a sensitivity to reduce to below the level of sensitivity. Accordingly, an instruction causes a UI design tool to move a UI element in the future UI design to a second area.
