To stop erroneous button presses, allow users to add a deadzone between the button via the Settings > General > System menu > Touch Dead Zone. The configuration was chosen this way: the touchpad has the same DPI in both direction so the setting applies the same on both the X and Y axis. The setting ranges from 0 to 100 and is internally multiplied by 2 giving a maximum deadzone of 2*100 = 200 around each button, which account for 400 total (once around each button), effectively reducing each virtual button from 1000x600 to 600x200 when using the maximum value.
